Whitening is the most-requested cosmetic dental treatment in Anchorage, and for good reason — it's fast, conservative and affordable compared to veneers. But not all whitening is equal. Drugstore strips use lower concentrations and ill-fitting trays that can irritate gums, while professional whitening is calibrated to your enamel and the stains you actually have.
Your Three Real Options
In-Office Whitening (~$450–$650)
One 60–90 minute visit. We isolate your gums, apply a high-strength peroxide gel, and activate it with a curing light. Results are immediate — typically 4–8 shades lighter.
Custom Take-Home Trays (~$300–$450)
We take impressions and fabricate trays that fit your teeth exactly. You wear them with prescription gel for 30–60 minutes a day over 1–2 weeks. Gentler and great for maintenance.
Drugstore Strips (~$25–$60)
Convenient but limited. Strips don't cover the curved surfaces of back teeth well and can cause sensitivity in patients with thin enamel or receding gums.
What About Sensitive Teeth?
Sensitivity is the #1 reason at-home whitening fails. In a professional setting we can pre-treat with desensitizing varnish, use a lower peroxide concentration, and stop early at the first sign of irritation — options strips don't give you.
Stains That Whitening Won't Fix
- Tetracycline antibiotic staining from childhood
- Trauma-darkened teeth (often need internal bleaching or a veneer)
- Existing crowns, veneers and tooth-colored fillings
- Deep fluorosis spots
For these, veneers or bonding are usually the better answer. Dr. Kennedy will tell you honestly before you spend money on a treatment that won't deliver.
Frequently Asked Questions
How long does professional teeth whitening last?
Results typically last 1–3 years depending on your diet (coffee, red wine, tea), smoking and oral hygiene. Touch-ups with take-home trays every 6–12 months keep your smile bright.
Will whitening damage my enamel?
No. Professional whitening at clinically-tested concentrations does not weaken enamel. The peroxide breaks apart stain molecules without altering tooth structure.
Can I whiten my teeth if I have crowns or veneers?
Crowns, veneers and tooth-colored fillings do not change color. We'll plan whitening before replacing restorations, so the new ones match your brighter shade.
How white is too white?
We aim for a shade that complements your skin tone and the whites of your eyes. Going further than that starts to look artificial. Dr. Kennedy will guide you to a natural, age-appropriate result.
