If your teeth have become discolored, teeth whitening can restore your smile’s original brilliance.
If you dream of celebrity smile but you’re so hung up about the color of your teeth you daren’t open your mouth in public, tooth whitening could come to your rescue.
Tooth whitening (or bleaching) can be done either at the dentist’s or at home.
Either way, it involves lightening the color of your tooth enamel using a hydrogen-peroxide or oxygenated water-based gel.
The procedure is painless.
Dentist bleaching is carried out at a dentist’s in one or two sessions.
The dentist first creates a protective shield for your gums from a teeth impression and then applies the highly concentrated whitening gel to your teeth for between 20 and 90 minutes, depending on what condition they’re in.
In certain cases, a high-energy or laser light may be used to accelerate the whitening process.
Laser whitening treatment is also available.
At-home bleaching also requires a shield for your teeth, but the gel used is less concentrated and can be applied at home. You leave it on for between 15 minutes and an hour a day for 15 days. It’s also possible to have a whitening session at the dentist’s followed by a course of home whitening.
The results are good for an average of 4 years if you don’t expose your teeth to much tobacco or caffeine.
