Reports vary, but most whitening dentists trust you to whiten once a year chairside, with touchups on your own in between. If you are using exclusively at-home products, it is generally accepted that you can use them safely once a day—but only for two weeks at a time.
Our expert in teeth whitening in Northridge always recommends chairside service, since the chemicals are stronger and you can get many shades of brightness in one session. However, if you are on a budget or just prefer the DIY aspect of over-the-counter products, you may see some positive results on your own. Just remember, hydrogen peroxide can be extremely detrimental to your enamel if used incorrectly.
If you drink lots of coffee, you may need to whiten more often than someone who exclusively drinks water or clears. If you have problems with discoloring, you should schedule a dental exam and cleaning before making your next whitening appointment. Clean teeth always whiten better.
You can tell you are overwhitening if you start to have symptoms like increased tooth sensitivity or burning in your gums. If these occur, cease whitening treatments immediately and contact your Northridge cosmetic dentist.
