Book a Whitening Consultation
Newport Dental in Factoria offers professional teeth whitening using the Opalescence system from Ultradent. Unlike over-the-counter whitening strips and generic trays, Opalescence uses dentist-supervised concentrations that deliver noticeable results without unnecessary sensitivity. We offer both in-office chairside whitening and custom take-home tray kits so you can choose the approach that fits your schedule, your goals, and your comfort level.
Professional whitening is most effective on natural tooth enamel and works best when done after a dental cleaning. Crowns, veneers, and fillings do not respond to whitening agents, so your dentist will evaluate your teeth before recommending a treatment plan. We serve patients across Bellevue, Newcastle, Renton, and the Eastside. Call us at 425-641-5303 to schedule your whitening consultation.

Professional-Grade Whitening That Goes Beyond Strips and Store-Bought Kits
Over-the-counter whitening products use lower concentrations of bleaching agents and one-size-fits-all trays that do not seal properly against your teeth. This leads to uneven results, longer treatment times, and more gum irritation. Professional whitening at Newport Dental uses the Opalescence system with concentrations matched to your teeth and custom-fitted trays that keep the gel in place and off your gums.
Why Professional Whitening Works Better
The Opalescence system uses professional-strength hydrogen peroxide or carbamide peroxide gels that penetrate enamel more effectively than drugstore products. Your dentist selects the right concentration based on your current shade, your sensitivity history, and how quickly you want results. Custom trays ensure even contact with every tooth surface, which prevents the streaky or patchy results common with store-bought strips.
What Causes Tooth Discoloration
Teeth discolor over time from coffee, tea, red wine, tobacco, and certain medications. Age also plays a role as enamel thins and the yellowish dentin layer underneath becomes more visible. Professional whitening breaks apart these stain molecules within the enamel and dentin, restoring a brighter appearance. Your dentist will let you know what kind of results to expect based on the type and depth of your staining.
Who Is a Good Candidate for Whitening
Whitening works best on natural tooth enamel that has yellowed or stained over time. It is not effective on crowns, veneers, bonding, or fillings, which means patients with visible restorations on their front teeth may see uneven color after whitening. Patients with untreated cavities or gum disease should address those issues first. Your dentist will evaluate your teeth at the consultation and recommend the best path forward.
In-Office Whitening: Visible Results in a Single Appointment
For patients who want faster results, our in-office Opalescence chairside whitening can lighten your teeth by one to two shades per session. Each appointment includes three whitening sessions performed back to back, so you walk out noticeably brighter in about 90 minutes.
Custom Take-Home Whitening Trays for Gradual, Comfortable Results
If you prefer to whiten on your own schedule or have sensitive teeth, custom take-home trays with Opalescence gel in a lower concentration give you control over the pace and intensity of your whitening. The trays are made from impressions of your teeth for a precise fit that keeps the gel evenly distributed.
How Take-Home Whitening Works
Your dentist takes impressions of your teeth and has custom-fitted trays fabricated. You receive 10 pre-loaded Opalescence gel trays in a 10% to 15% concentration. You wear one tray per day for 10 consecutive days. The lower concentration works gradually, which reduces the chance of sensitivity while still delivering professional-level results. The custom fit ensures the gel stays on your teeth and away from your gum tissue.
Touch-Up Trays and Maintenance
If you finish the 10-day cycle and want further improvement, touch-up trays are available from our office. Many patients use a touch-up cycle once or twice a year to maintain their results after consuming staining foods and beverages. For patients who want additional shade control beyond the take-home trays, over-the-counter whitening products can be used as a maintenance step between professional treatments.
Take-Home vs. In-Office: Choosing the Right Option
Take-home trays work well for patients who want a more gradual whitening process, have sensitive teeth, or prefer the convenience of whitening at home. In-office whitening is better for patients who want immediate results or prefer a hands-off experience supervised by their dentist. Some patients start with an in-office session for a quick boost and then use take-home trays for ongoing maintenance. Your dentist will help you decide at your consultation.
Minimizing Sensitivity With Dentist-Supervised Whitening
Tooth sensitivity is the most common concern patients have about whitening. Professional supervision makes a significant difference because your dentist selects the right concentration, monitors your response, and adjusts the treatment plan if sensitivity develops.
How We Reduce Sensitivity Risk
Opalescence gels are formulated with potassium nitrate and fluoride to help protect enamel and reduce sensitivity during treatment. For take-home trays, we start with a lower concentration (10% to 15%) that is gentler on teeth while still being effective. For in-office whitening, a protective gum barrier is applied before the gel is placed, which prevents the higher-concentration formula from irritating soft tissue.
What If I Have Sensitive Teeth Already
Patients with existing sensitivity can often still whiten safely with the take-home tray option at the lower 10% concentration. Your dentist may also recommend using a sensitivity toothpaste for two weeks before starting treatment. If sensitivity develops during the 10-day take-home cycle, you can pause for a day or two and resume without affecting the final result. Every patient responds differently, and your dentist will tailor the plan to your comfort level.
Is Teeth Whitening Safe for Enamel
Professional whitening using ADA-accepted products like Opalescence does not damage healthy enamel when used as directed. The hydrogen peroxide and carbamide peroxide gels used in professional whitening have been studied extensively and are considered safe for supervised use. Over-whitening or using unregulated products purchased online can cause enamel erosion, which is another reason professional supervision matters.
Teeth Whitening Cost and Payment Options
Teeth whitening is classified as a cosmetic procedure by dental insurance companies and is typically not covered by insurance plans. However, the investment in professional whitening is significantly more effective and longer-lasting than repeatedly purchasing over-the-counter products.
What Affects the Cost of Whitening
The cost of professional whitening at Newport Dental depends on the treatment option you choose. In-office chairside whitening and custom take-home tray kits are priced differently based on the materials, chair time, and concentration involved. Your dentist will provide a clear cost estimate at your consultation so there are no surprises.

Teeth Whitening FAQs
How long does professional teeth whitening last?
Professional whitening results typically last six months to two years depending on your diet, oral hygiene, and lifestyle. Coffee, tea, red wine, and tobacco can cause staining to return more quickly. Touch-up trays from our office help maintain your results between treatments.
Does teeth whitening cause sensitivity?
Some patients experience temporary sensitivity during or after whitening, especially with higher concentrations. Opalescence gels contain potassium nitrate and fluoride to help minimize this. Take-home trays use a lower concentration (10% to 15%) that is gentler on sensitive teeth. If sensitivity develops, you can pause the treatment for a day or two and resume without affecting your results.
What is the difference between in-office and take-home whitening?
In-office whitening uses a 40% hydrogen peroxide gel applied by your dentist in three sessions during a single 90-minute appointment. You see results immediately. Take-home whitening uses custom trays with a 10% to 15% gel worn once daily for 10 consecutive days. Results are more gradual but the lower concentration is gentler on sensitive teeth.
Does insurance cover teeth whitening?
Teeth whitening is classified as a cosmetic procedure and is typically not covered by dental insurance. Newport Dental offers payment and financing options to make professional whitening accessible. Ask our front desk about available plans when you schedule your consultation.
Can I whiten my teeth if I have crowns or veneers?
Whitening agents only work on natural tooth enamel. Crowns, veneers, bonding, and fillings will not change color with whitening treatment. If you have visible restorations on your front teeth, whitening the surrounding natural teeth may create a color mismatch. Your dentist will evaluate this at your consultation and recommend the best approach.
How many shades whiter will my teeth get?
Results vary by patient. In-office whitening typically lightens teeth by one to two shades per session. Take-home trays produce gradual lightening over the 10-day cycle. The final result depends on your starting shade, the type of staining, and your enamel thickness. Your dentist will discuss realistic expectations at your consultation.
Is teeth whitening safe?
Professional whitening with ADA-accepted products like Opalescence is safe for healthy enamel when supervised by a dentist. The gels have been studied extensively and do not damage enamel when used as directed. Over-whitening or using unregulated products purchased online can cause enamel erosion, which is why professional supervision is recommended.
Should I get my teeth cleaned before whitening?
Yes. Professional whitening works best when done after a dental cleaning. Removing plaque, tartar, and surface stains allows the whitening gel to contact your enamel directly, which produces more even and effective results. If it has been more than six months since your last cleaning, schedule one before your whitening appointment.
