Please don't hesitate to call us at (202) 920-1410
A brighter smile is one of the most immediate cosmetic improvements available in dentistry — and professional whitening delivers results that over-the-counter strips, trays, and toothpastes simply cannot match.
The difference comes down to concentration, precision, and clinical supervision. At Georgetown Advanced Dentistry, Dr. Sinclair Davis, DDS, offers professional whitening options tailored to the sensitivity level, lifestyle, and aesthetic goals of each patient. Whether you want a single-session in-office result with Philips Zoom!® or a supervised take-home protocol, the approach is calibrated to your specific situation — not a one-size-fits-all kit. We serve patients throughout Washington, DC, including Georgetown, Chevy Chase, Tenleytown, American University Park, Friendship Heights, and Northwest DC.
Shade Change That Shows
Professional whitening produces measurable shade improvement — not marketing improvement. Up to eight shades whiter in a single Philips Zoom!® session.
Professional vs. Over-the-Counter
Store-bought whitening strips can produce modest results — but the differences in concentration, safety, and outcome are significant.
Over-the-Counter
Store-bought strips and gels use low-concentration peroxide with no clinical supervision or gum protection.
- Typically 1–2 shades of improvement
- Results may take weeks to appear
- Higher risk of gum irritation or sensitivity
- One-size-fits-all approach
- Cannot address deeper staining
Professional Whitening
Clinical-grade concentrations applied under controlled conditions with protective barriers for gums and soft tissue.
- Up to 8 shades whiter, dramatic results
- Visible results in a single visit
- Monitored by dental professionals
- Personalized to your sensitivity level
- Custom take-home trays available
Choose Your Whitening Path
Whether you want dramatic results in one appointment or a gradual approach on your schedule — both paths are available.
In-Office with Philips Zoom!®
One Visit · Measurable Shift
Performed entirely at Georgetown Advanced Dentistry in a single appointment. After a professional cleaning to remove biofilm, a protective barrier isolates the gums, and clinical-strength hydrogen peroxide gel is applied to the teeth and activated by LED light in three 15-minute intervals. A fluoride gel afterward addresses any sensitivity.
Custom Take-Home Trays
Weeks · On Your Schedule
Custom-fabricated trays made from a precise digital impression of your teeth. Because the trays fit exactly to your smile, the whitening gel stays in contact with the tooth surface and away from the gum tissue — something generic strips cannot achieve. Ideal for patients who prefer gradual improvement or have sensitivity.
What Whitening Can & Cannot Fix
Not all discoloration responds equally to bleaching. Understanding which type of staining you have determines what will actually work.
What Whitening Handles Well
Extrinsic staining — discoloration on the outer surface of the tooth. Highly responsive to professional whitening.
- Coffee, tea, and red wine stains
- Food pigments (berries, tomato-based sauces)
- Tobacco staining
- Age-related yellowing
- Generalized dullness or discoloration
Where Whitening Falls Short
Intrinsic staining — discoloration inside the tooth structure. Better addressed with veneers or microabrasion.
- Tetracycline (antibiotic) staining
- Fluorosis discoloration
- Trauma-induced gray or dark teeth
- Certain developmental conditions
- Existing restorations (crowns, veneers, fillings)
Whitening First — Then Restorations
Whitening agents work only on natural tooth structure. Composite fillings, crowns, and veneers retain their original shade while surrounding teeth lighten. If you're planning cosmetic restorations, whitening should be completed first so restorations can be matched to your brightened smile. Dr. Davis factors this into any comprehensive cosmetic treatment plan.
Frequently Asked Questions
Straight answers to what patients ask most about professional teeth whitening.
Is professional whitening better than over-the-counter options?
Significantly, for most patients. Professional treatments use higher concentrations of hydrogen peroxide applied under clinical conditions with protective barriers that prevent gum irritation. The results are more dramatic, more predictable, and achieved faster. Over-the-counter products can produce modest improvement for mild staining but are not a substitute for professional treatment when meaningful shade change is the goal.
Will professional teeth whitening damage my enamel?
Clinical research consistently shows that professionally supervised whitening is safe for both tooth structure and systemic health. Any minor, transient effects on enamel surface properties are comparable to those from normal daily acid exposure — well within safe parameters. The key is clinical supervision: using the appropriate concentration, protecting soft tissue, and monitoring the process. That is what separates professional whitening from unsupervised home use of strong agents.
What exactly happens during a whitening appointment?
The appointment begins with a professional cleaning to ensure the whitening gel makes direct contact with the tooth surface. The gums and soft tissue are then isolated with a protective barrier. A clinical-strength hydrogen peroxide gel is applied to the teeth and activated by LED light in three 15-minute intervals. The gel is removed, the protective barrier is taken off, a fluoride gel is applied for sensitivity, and your shade improvement is assessed. The whole process takes approximately 60 to 90 minutes.
Can I get teeth whitening if I have sensitive teeth?
Yes — with the right approach. Georgetown Advanced Dentistry evaluates sensitivity before recommending a whitening protocol and can adjust accordingly. Options include desensitizing agents applied before and after treatment, lower-concentration gels used over a longer period via custom take-home trays, or laser-activated whitening that reduces chemical exposure time while maintaining effectiveness. Sensitivity is rarely a barrier to whitening; it's simply a factor that shapes which protocol is most appropriate.
How long do whitening results last?
Typically one to three years, depending on diet and lifestyle. Coffee, tea, red wine, and tobacco are the primary factors that accelerate re-staining. Custom take-home trays from Georgetown Advanced Dentistry make touch-up maintenance simple — a few nights of wear restores brightness without the need for another full in-office session.
