How Often Should You Whiten Your Teeth?

Professional teeth whitening performed in the dentist's office is typically recommended once a year or every 18 months, depending on the duration of the results. Home kits can be used up to once every four to six months, but it's best to have your teeth whitened by a professional if you're going to buy several home kits and use them one after the other. Smile teeth whitening pens are the first patented revolutionary system that allows you to whiten, strengthen and rebuild enamel. If you are pregnant, have a known allergy to hydrogen peroxide or carbamide, or are under 16 years old, it's best to avoid professional teeth whitening. Home teeth whitening treatments, such as trays and strips, work very well when there are only a few shades of stain left to remove.

However, deeper discoloration responds better to professional teeth whitening treatment for more dramatic results. This is usually a system of strips to take home every 3 to 6 months, or just a few days on whitening trays to brighten your teeth. The results of professional teeth whitening are instant and usually last between four and six months. If you want to know how often you can whiten your teeth with strips, you might need something stronger. Even if you follow the manufacturer's instructions well, you may not get the results you're looking for.

If you whiten your teeth all the time and don't see the desired outcome, ask your dentist about professional in-office whitening treatment. Whether you use commercial whitening strips or a home kit from your dentist, most dental professionals recommend touching up every 3 or 4 months or after every dental cleaning.
