04 Common Questions

Dental implant FAQs

Will I have a gap while my implant heals?
Temporary tooth options depend on the location of the missing tooth and your treatment plan. At your consultation, our team will explain what may work during healing.
Could I need treatment in addition to the implant?
Some cases need an extraction or bone grafting. We assess your teeth and bone, explain any additional care recommended and include it in your personalized estimate.
What will I learn at my consultation?
We discuss your concerns, possible treatment options, expected timing and payment choices. Our team will explain any further examination or imaging needed to complete your plan.
Am I a candidate for dental implants?
Your dentist considers your oral health, bone support, medical history and healing risks. Smoking and some health conditions can affect outcomes. An examination is needed to determine suitability.
Can I get an implant after a tooth extraction?
Discuss replacement planning before an extraction when possible. Ask whether placement at the time of extraction or a later appointment would be appropriate, and what temporary tooth options you would have while healing.
Are dental implants better than a bridge or dentures?
The right choice depends on your remaining teeth, oral health, budget and preferences. Compare the proposed options, including maintenance, surgery and expected treatment time, with your dentist.
What should I know about recovery and risks?
Implants involve surgery. Potential complications include infection, injury to nearby structures and implant failure. Ask about comfort measures, recovery instructions and your individual risks. Contact your dental provider promptly if an implant becomes loose or painful.
How long will my dental implant last?
There is no guaranteed lifespan. Health, healing, daily cleaning and follow-up care affect long-term results. Ask about maintenance and whether the replacement tooth or other components may need repair or replacement.

Tooth Extractions in Renton, WA

Tooth Extractions
in Renton, WA

A damaged or painful tooth does not always need removal. At Epic Dental in Renton, we evaluate whether it can be saved before planning a tooth extraction.

A dentist explaining care during a patient consultation

01 Your Options

When is a tooth extraction needed?

We assess the tooth and surrounding bone before recommending removal. When appropriate, we discuss options to preserve the tooth and plan for replacement.

  • Severely damaged teeth
  • Teeth affected by infection
  • Impacted or crowded teeth

Before and after tooth removal

Simple or surgical extraction?

A visible, accessible tooth may be removed with a simple extraction. A broken or impacted tooth can need a surgical approach. Imaging helps us discuss the plan and whether a specialist is appropriate.

Protecting the healing area

Follow your written aftercare instructions to protect the blood clot. Contact the office for persistent bleeding, increasing pain or concerns about healing. Discuss any planned tooth replacement before removal when possible.

Explore dental implants after tooth removal.

Sedation options for your visit

Feeling nervous about dental treatment? Oral sedation and nitrous oxide sedation are available options. Talk with our team about which option may fit your needs.

02 What to Expect

Your tooth extraction appointment

  1. 01

    Evaluate

    Examine the tooth and review imaging and alternatives.

Tooth extraction cost & insurance

The fee depends on whether the tooth can be removed simply or needs a surgical approach. Imaging, sedation and bone grafting, if recommended, may affect the estimate.

We’ll explain the recommended treatment and expected patient portion. Deductibles, plan limits and covered services can affect what you pay.

How long does healing take?
Recovery varies with the tooth and procedure. We’ll explain what to expect.
Can I replace the tooth?
Depending on your needs, an implant or bridge may be an option.
Do you evaluate wisdom teeth?
We can assess wisdom-tooth concerns and discuss whether removal or referral for surgical care is appropriate.
Can I return to work after an extraction?
The procedure, sedation and your type of work affect timing. Arrange recovery time based on the instructions for your visit.
What if pain increases after a few days?
Contact the office. Increasing pain can need an examination; do not assume it is a normal part of healing.

Oral Sedation Dentistry
in Renton, WA

Dental anxiety can make it hard to schedule care. Ask Epic Dental in Renton about oral sedation and a treatment plan that takes your concerns seriously.

A dentist explaining care during a patient consultation

01 Your Options

Is oral sedation right for your visit?

Oral sedation uses prescribed medicine to help you relax. We review your health, medications and treatment before deciding whether it is appropriate.

  • Discuss dental anxiety
  • Review your health and medications
  • Receive clear preparation instructions

Oral sedation or laughing gas?

Different ways to relax

Oral sedation uses prescribed medication, while nitrous oxide is inhaled through a nose mask. Your health, anxiety and planned treatment help determine the appropriate option.

Plan the whole day

Arrange a responsible adult escort and follow your written instructions about food, drinks and medications. Do not drive after oral sedation. Ask the team when you may resume work and other activities.

Compare nitrous oxide (laughing gas).

02 What to Expect

Preparing for oral sedation

  1. 01

    Plan safely

    Review your health and sedation options in advance.

  2. 02

    Prepare

    Follow your prescribed instructions and arrange a responsible adult escort.

  3. 03

    Rest afterward

    Allow time to recover and follow your discharge instructions.

03 Cost & Insurance

Oral sedation fees & coverage

Ask for sedation and dental treatment to be explained separately in your estimate. Insurance may limit sedation benefits, so coverage should be checked before the appointment.

Let’s review your estimate.

We’ll review the planned sedation fee alongside your dental treatment. Ask about coverage requirements and payment options before your visit.

04 Common Questions

Oral Sedation
FAQs

Will I be asleep?
Oral sedation is not the same as general anesthesia. Your level of relaxation can vary.
Can I drive afterward?
No. Arrange an adult escort and follow the office’s restrictions after sedation.
Is it the same as numbing?
No. Local anesthesia may still be needed for the dental procedure.
Can I choose sedation on the day of treatment?
Please discuss it in advance. A medical review, preparation instructions and an escort may need to be arranged.
Can I take my own anxiety medicine beforehand?
Tell the dentist about all medications. Do not add or change a dose for the visit unless instructed by the treating clinician.
Can sedation help if I have avoided the dentist?
It may be one part of your plan. Start by explaining what makes visits difficult so we can discuss practical comfort options.

in Renton, WA

Considering Invisalign in Renton? Explore removable clear aligners for crowding, gaps and selected bite concerns with the team at Epic Dental.

Dr. Koo discussing a digital dental scan

01 Your Options

What can Invisalign treat?

Invisalign uses a sequence of custom aligners to move teeth gradually. We evaluate your bite and goals to see whether aligners fit your needs.

  • Crowding
  • Spaces between teeth
  • Selected bite concerns

Living with clear aligners

Daily wear matters

Invisalign aligners are typically worn 20–22 hours a day, following your dentist’s instructions. Remove them for meals and cleaning. Consistency helps your teeth follow the planned movements.

Aligners or veneers?

Aligners move teeth; veneers change their visible surface. If your concern is crowding or bite alignment, discuss orthodontic treatment before deciding on a cosmetic restoration.

Compare veneers for tooth shape and color concerns.

02 What to Expect

How Invisalign treatment works

  1. 01

    Assess & plan

    Examine your bite and discuss your alignment goals.

  2. 02

    Follow your wear schedule and progress through each set.

  3. 03

Your estimate depends on the complexity and length of treatment. Ask whether retainers and any additional aligners are included, and whether your plan offers orthodontic benefits.

Let’s review your estimate.

Orthodontic benefits can have age restrictions or lifetime limits. Bring your insurance details so we can help you understand what may apply.

Insurance information Monthly payment options

04 Common Questions

Invisalign
FAQs

Can I remove the aligners?
Yes—for eating and cleaning. Consistent wear as prescribed is important.
How long will it take?
Timing depends on the movements needed and your progress.
Are aligners right for every bite?
Some cases need other orthodontic treatment. Your exam helps determine the best approach.
Will I need retainers after Invisalign?
Yes. Retainers help maintain your teeth’s new positions. Follow the wear schedule recommended after treatment.
Does Invisalign hurt?
Pressure or temporary soreness can occur when starting a new set. Tell the team if an aligner causes persistent irritation or does not fit.
Does dental insurance cover Invisalign?
Some plans include orthodontic benefits; others do not. Age restrictions and lifetime limits may apply. We can help check your plan.

Nitrous Oxide Sedation in Renton, WA

Nitrous Oxide Sedation
in Renton, WA

Looking for laughing gas during dental treatment? Epic Dental in Renton can discuss nitrous oxide to help you relax while remaining awake and responsive.

A dentist explaining care during a patient consultation

01 Your Options

How does laughing gas work?

Nitrous oxide is mixed with oxygen and breathed through a small nose mask. The team adjusts the flow and monitors you during treatment.

  • Breathed through a nose mask
  • Adjustable during your visit
  • Used alongside local anesthesia when needed

Know your dental comfort options

A nose mask, not a pill

You breathe a mixture of nitrous oxide and oxygen through your nose. The dentist adjusts it during treatment. Local anesthesia may still be needed to numb the treatment area.

After the mask is removed

The effects usually wear off soon after nitrous oxide stops. The team checks your recovery and gives discharge instructions, including whether you can drive based on all medicines used.

Explore oral sedation for dental anxiety.

02 What to Expect

Your visit with nitrous oxide

  1. 01

    Review

    Discuss your medical history and comfort needs.

  2. 02

    Relax

    Breathe through the mask while the team monitors you.

  3. 03

    Recover

    Allow the effects to wear off and receive discharge guidance.

03 Cost & Insurance

Nitrous oxide cost & insurance

The fee may be separate from the dental procedure. Ask how the duration of treatment affects the estimate and whether your insurance includes a sedation benefit.

Let’s review your estimate.

Ask whether laughing gas is covered for the procedure you need. Your plan and the treatment estimate help clarify the expected cost.

Insurance information Monthly payment options

04 Common Questions

Nitrous Oxide Sedation
FAQs

Is laughing gas general anesthesia?
No. You generally remain awake and able to respond.
Will I still need numbing?
Often, yes. Nitrous oxide does not replace local anesthesia for every procedure.
Can everyone use it?
Your health and ability to breathe through your nose affect suitability. Ask at your consultation.
How is laughing gas different from oral sedation?
Nitrous oxide is inhaled and adjustable during treatment. Oral sedation uses prescribed medicine and requires advance planning and an adult escort.
What if my nose is blocked?
Let the office know. A blocked nose can make it difficult to breathe through the mask.
Can I return to normal activities afterward?
Follow the team’s discharge advice. Your procedure and any additional medicines affect when it is appropriate to resume activities.

Refine tooth shape, color and small gaps with dental veneers in Renton. At Epic Dental, we start with your goals and the health of your natural teeth.

Dr. Koo discussing a digital dental scan

01 Your Options

What can dental veneers change?

Veneers cover the front surface of selected teeth. We review your goals, enamel and bite, then compare veneers with other ways to improve your smile.

  • Uneven tooth shapes
  • Selected chips or small gaps
  • Color concerns

Compare your smile options

Porcelain or composite?

Porcelain veneers are custom-made shells; composite uses tooth-colored resin. They differ in preparation, repair and maintenance. Ask which material suits your teeth and whether it is part of your proposed plan.

Veneers, crowns or aligners?

Veneers change a tooth’s front surface. Crowns cover more of the tooth when support is needed. Aligners change tooth position. Your enamel, bite and goals help guide the choice.

Explore Invisalign for crowding and alignment.

02 What to Expect

Let’s review your estimate.

Cosmetic treatment and medically necessary care may be handled differently by your plan. Review your written estimate before choosing treatment.

Insurance information Monthly payment options

04 Common Questions

Dental Veneers
FAQs

Are veneers reversible?
Preparation often removes enamel, so treatment is generally irreversible.
Do I need a veneer on every tooth?
No. The number depends on your goals and the visible balance of your smile.
Will veneers need replacement?
They may need repair or replacement over time. Cleaning and bite protection matter.
Can I get veneers if I grind my teeth?
Grinding can place stress on restorations. Discuss your bite and whether protection or a different treatment is appropriate.
Can veneers replace missing teeth?
No. Veneers attach to existing teeth. A bridge or implant may be considered for a missing tooth.
Does insurance pay for veneers?
Cosmetic veneers are often excluded. Any benefits depend on your plan and the reason for treatment.

A cracked, worn or heavily filled tooth may need more support. Explore custom dental crowns at Epic Dental in Renton, designed around your tooth and bite.

Dr. Koo discussing a digital dental scan

01 Your Options

When does a tooth need a crown?

A crown covers a tooth that needs more support than a filling can provide. We assess the remaining tooth structure before recommending treatment.

  • Large areas of damage
  • Selected cracked teeth
  • Protection after root canal treatment

Understand your tooth restoration

Crown or filling?

A filling replaces a damaged area; a crown covers the tooth to provide broader support. The amount and location of remaining tooth structure help determine which option is appropriate.

While you have a temporary crown

A temporary crown protects the prepared tooth while the final restoration is made. Follow the office’s eating and cleaning instructions, and call if it becomes loose or your bite feels uncomfortable.

Learn about crowns after root canal treatment.

02 What to Expect

How a dental crown is placed

  1. 01

04 Common Questions

Dental Crowns
FAQs

Do I need a crown or a filling?
It depends on the size and location of the damage and the remaining tooth structure.
How do I care for a crown?
Brush, clean between teeth and keep regular dental appointments.
Will it look like my other teeth?
We discuss material and shade to suit the tooth’s location and your goals.
How many visits does a crown take?
A lab-made crown usually involves a preparation visit and a fitting visit. The team will explain the schedule for your plan.
What if my crown comes loose?
Call the office, keep the crown if possible and avoid chewing on that tooth. Do not reattach it with household glue.
Can a crowned tooth still get a cavity?
Yes. The tooth around the crown’s edges still needs daily cleaning and regular examination.

Lingering tooth sensitivity or pain when biting can need an exam. Epic Dental in Renton helps you understand whether root canal treatment can preserve your tooth.

A dentist explaining care during a patient consultation

01 Your Options

Signs a tooth may need root canal treatment

Root canal treatment removes inflamed or infected pulp, cleans the canals and seals them. A final restoration protects the tooth afterward.

  • Persistent tooth pain
  • Lingering temperature sensitivity
  • Inflamed or infected tooth pulp

Relieve the problem. Protect the tooth.

Root canal or extraction?

Root canal treatment aims to keep a tooth that can be restored. Extraction removes it. We assess the damage and supporting structures before discussing the options and any replacement needs.

After your appointment

Follow the aftercare instructions and complete the recommended restoration. Avoid chewing heavily on the tooth until it is protected. Contact us for worsening symptoms or problems with a temporary filling.

04 Common Questions

Root Canal Treatment
FAQs

Will I need a crown afterward?
Many treated teeth need a crown. The recommendation depends on the tooth and remaining structure.
Will I need a specialist?
Complex cases may be referred to an endodontist.
What about soreness afterward?
Some tenderness can occur. Follow your aftercare plan and contact us if symptoms worsen.
Is root canal treatment painful?
Local anesthesia is used for comfort. Some tenderness afterward can occur; tell your dentist about pain or swelling that worsens.
How many appointments will I need?
Treatment may take one or more visits depending on the tooth and infection. A final restoration may require another appointment.
Can antibiotics replace a root canal?
They do not remove damaged tissue from inside a tooth. The exam determines what treatment is needed for the underlying problem.

Missing one or more teeth? Explore a fixed dental bridge at Epic Dental in Renton and compare support from natural teeth or dental implants.

A dentist explaining care during a patient consultation

01 Your Options

How does a dental bridge replace teeth?

A bridge holds replacement teeth across a gap. We evaluate the supporting teeth, gum health and bite before comparing options.

  • One or more missing teeth
  • Support from teeth or implants
  • A fixed replacement option

Choose support that fits your smile

Tooth-supported or implant-supported?

A traditional bridge uses neighboring teeth for support. An implant-supported bridge relies on implants. We assess your bone, gum health and nearby teeth before comparing the choices.

Care beneath the bridge

The replacement tooth does not remove the need for daily cleaning. Ask for a demonstration of a floss threader, interdental brush or other tool suited to your bridge.

Compare dental implants for missing teeth.

02 What to Expect

03 Cost & Insurance

Dental bridge cost & insurance

The number of replacement teeth, material and supporting teeth or implants affect your estimate. Ask which components are included and how your insurance applies to the proposed bridge.

Let’s review your estimate.

We’ll explain the recommended treatment and expected patient portion. Deductibles, plan limits and covered services can affect what you pay.

04 Common Questions

Dental Bridges
FAQs

Bridge or implant?
Your bone, neighboring teeth, budget and preferences help guide the choice.
How do I clean under a bridge?
Use the cleaning tools your dental team recommends to reach beneath the replacement teeth.
Will nearby teeth need shaping?
A traditional bridge usually requires reshaping supporting teeth. Other designs differ.
Is a bridge removable?
A fixed bridge stays in place. It differs from a removable partial denture.
Can a bridge replace more than one tooth?
Sometimes. The length of the gap and strength of the available support determine what is appropriate.
How long will a bridge last?
There is no guaranteed lifespan. Oral health, bite forces and maintenance affect when repair or replacement may be needed.

Having trouble breathing or swallowing? Seek emergency medical care. Call 911 for a life-threatening emergency.

01 Your Options

Tooth pain, broken teeth & urgent concerns

An exam and any needed imaging help us identify the problem. We discuss immediate care, ways to protect the tooth and whether follow-up treatment is needed.

  • Persistent toothache
  • Cracked or broken teeth
  • Swelling or a lost restoration

What to do before your dental visit

Toothache or broken tooth

Avoid chewing on the affected side and call for advice. For a toothache, gently rinse with warm water; do not place aspirin on the tooth or gums. Tell us about swelling or fever.

Knocked-out adult tooth

Seek dental care immediately. Handle the tooth by the crown, not the root, and keep it moist in milk if you cannot safely replace it. Do not reinsert a baby tooth.

Let’s review your estimate.

We’ll explain the recommended next step after examining the tooth. Call first for urgent concerns; an online appointment request is not an emergency response.

04 Common Questions

Tooth Pain & Emergency Care
FAQs

What should I tell the team when I call?
Describe the symptoms, when they started and any swelling, fever or injury. Mention a lost crown or filling and medicines you have taken.
Does tooth pain mean an extraction?
Not always. Treatment depends on the cause and whether the tooth can be restored.
When should I seek emergency medical care?
Trouble breathing or swallowing, or rapidly spreading swelling, needs emergency medical care. Call 911 for a life-threatening emergency.
Do you offer same-day emergency appointments?
Call for today’s availability. We can tell you the earliest opening and whether your symptoms require more urgent care.
What if a crown or filling falls out?
Keep the restoration if you have it, avoid chewing on that tooth and call. Do not use household glue to put it back.
Will antibiotics fix a tooth infection?
Antibiotics alone may not treat the underlying dental problem. An exam helps determine whether drainage, root canal treatment or another procedure is needed.

04 Common Questions

Dental implant FAQs

Will I have a gap while my implant heals?
Temporary tooth options depend on the location of the missing tooth and your treatment plan. At your consultation, our team will explain what may work during healing.
Could I need treatment in addition to the implant?
Some cases need an extraction or bone grafting. We assess your teeth and bone, explain any additional care recommended and include it in your personalized estimate.
What will I learn at my consultation?
We discuss your concerns, possible treatment options, expected timing and payment choices. Our team will explain any further examination or imaging needed to complete your plan.
Am I a candidate for dental implants?
Your dentist considers your oral health, bone support, medical history and healing risks. Smoking and some health conditions can affect outcomes. An examination is needed to determine suitability.
Can I get an implant after a tooth extraction?
Discuss replacement planning before an extraction when possible. Ask whether placement at the time of extraction or a later appointment would be appropriate, and what temporary tooth options you would have while healing.
Are dental implants better than a bridge or dentures?
The right choice depends on your remaining teeth, oral health, budget and preferences. Compare the proposed options, including maintenance, surgery and expected treatment time, with your dentist.
What should I know about recovery and risks?
Implants involve surgery. Potential complications include infection, injury to nearby structures and implant failure. Ask about comfort measures, recovery instructions and your individual risks. Contact your dental provider promptly if an implant becomes loose or painful.
How long will my dental implant last?
There is no guaranteed lifespan. Health, healing, daily cleaning and follow-up care affect long-term results. Ask about maintenance and whether the replacement tooth or other components may need repair or replacement.
