Health Tip: If You Want Whiter Teeth

(HealthDay News) -- There are many over-the-counter toothpastes, gels and strips that can help brighten and whiten your teeth. There are also several procedures that your dentist can perform to remove stains and discoloration from your not-so-pearly whites.
Before you invest in any of these solutions, the American Dental Hygienists' Association (ADHA) recommends that you have a complete dental checkup to be sure your dental health is good.

Some tooth whitening methods have side effects, the ADHA says. Some may cause increased sensitivity in teeth or pain or irritation in the gums. Others may be particularly high in acid, which can damage the protective enamel on teeth.
Before you begin any at-home tooth bleaching or whitening system, talk with your dentist, the ADHA advises.
