A bright, white smile is one of the most requested cosmetic improvements by dental patients in Redwood City and across the Bay Area. Teeth whitening is among the safest, most affordable, and most dramatic cosmetic dental treatments available, but not all whitening methods are equal. This guide breaks down your options and helps you decide what's right for your smile.
Why Do Teeth Stain?
Tooth discoloration falls into two main categories:
Extrinsic Stains
Affect the outer surface of enamel, caused by:
- Coffee, tea, and red wine
- Tobacco use
- Highly pigmented foods (berries, tomato sauce)
- Poor oral hygiene
Intrinsic Stains
Occur within the tooth structure, caused by:
- Aging (enamel thins over time)
- Certain antibiotics taken during childhood
- Excessive fluoride during tooth development
- Trauma or root canal treatment
The type and depth of staining determines which whitening treatment will be most effective.
Your Whitening Options
Option 1: In-Office Professional Whitening
Fastest & Most EffectiveBest for: Patients wanting fast, dramatic results; those with a special event coming up; moderate-to-heavy staining.
- Strongest whitening agents available (35–40% hydrogen peroxide)
- Results are immediate, up to 6 to 10 shades brighter in one visit
- Supervised by a dentist for sensitivity management
- Customized to your shade goals
Cost: $499 for a single in-office session.
Option 2: Custom Take-Home Whitening Trays
Best ValueBest for: Patients who want professional results at their own pace; those with mild to moderate staining; ongoing touch-up maintenance.
- Custom trays ensure even coverage and prevent gel from contacting gums
- More affordable than in-office treatment
- Trays can be reused with refill gel for future touch-ups
Cost: $299 for custom trays + gel.
Option 3: Over-the-Counter Whitening
Budget OptionBest for: Maintaining results after professional whitening; patients with very mild surface staining.
- Widely available and affordable
- Good for maintaining results after professional treatment
Cost: $20–$60 for strips or trays.
Limitations: One-size-fits-all trays can cause gum irritation. Slower and less predictable results (1–3 shades over several weeks).
What About Whitening for Sensitive Teeth?
Tooth sensitivity is the most common side effect of whitening. If you have sensitive teeth, Dr. Dabak may recommend:
- Desensitizing gel applied before/after whitening
- A lower-concentration whitening formula used over more sessions
- Prescription fluoride treatments to strengthen enamel
What Whitening Cannot Fix
Bleaching agents do not whiten:
- Dental crowns, veneers, or bonding
- Teeth with significant intrinsic staining (tetracycline, trauma)
For these cases, Dr. Dabak may recommend porcelain veneers or dental bonding to achieve your desired shade.
