Teeth Whitening
Professional whitening lightens tooth color using peroxide gels — either in the office in about an hour, or with custom take-home trays over one to two weeks.
Draft guide — written with AI assistance and pending review by a licensed dental professional. It is general information, not dental advice.

Who it's for
Adults with stained or discolored teeth. Whitening does not change the color of crowns, veneers or fillings, and is not recommended during pregnancy.
How it goes
- 1The dentist checks that your teeth and gums are healthy enough
- 2Shade is recorded before treatment
- 3Gel is applied in office, or custom trays are made for home use
- 4Results are reviewed and touch-up options discussed
Recovery: Temporary sensitivity to cold is common for a day or two. Results fade gradually and last longer if you limit coffee, tea, red wine and tobacco.
What's included?
A treatment total is usually several line items added together. This is why two quotes for “the same” treatment can differ. Not every component below is required for every patient — your plan should list only what your case needs.

- Per arch vs. both arches

Questions to ask your dentist
- “Is the price per arch or for both?”
- “Are take-home trays included?”
- “Will my fillings or crowns change color too? (They won't.)”
Insurance tips
Cosmetic, so almost never covered. Some offices bundle take-home trays free with new-patient cleanings.
