Teeth Whitening
Teeth whitening brightens a faded or discolored smile.
465 Laurel St, San CarlosHow whitening works
Whitening gels use peroxide to lift stains from the enamel. Coffee, tea, red wine and tobacco are the most common causes of staining, and teeth also darken naturally with age.
Dr. Sing checks your teeth and gums first, because whitening works on natural enamel only. Crowns, veneers and fillings keep their original color, so she plans around them.
Who it helps
- Stains from coffee, tea, wine or tobacco
- Teeth that have yellowed with age
- A smile you want brighter before a wedding, an interview or photos
What to expect
An exam first
Dr. Sing confirms your teeth and gums are healthy and notes any crowns or fillings that will stay their current shade.
The whitening
She recommends the whitening approach that fits your teeth and your schedule and tells you how much change to expect.
Afterward
Some people feel sensitivity to cold for a day or two. It passes without treatment.
Common Questions
How long does whitening last?
It depends on what you eat and drink and whether you use tobacco. A touch-up restores the shade when it starts to fade.
Is whitening safe for my enamel?
Professional whitening under a dentist's supervision is safe for enamel. Temporary sensitivity is the most common side effect.
Will whitening change my crowns or fillings?
Whitening changes natural enamel only. Crowns, veneers and fillings stay the color they are.
