Teeth whitening products can work, but sometimes they cause more trouble than they're worth. They can weaken enamel and leave your teeth in a condition where they can easily break or develop cavities. It's best to talk to your dentist about teeth whitening choices which they recommend for your needs.
Brush twice daily for best results. It's especially important right after a meal and an essential right before bed time. If you do not brush, your teeth will have many harmful bacteria which can cause many problems, including cavities.
Brush your teeth at least 2 times a day. This will help prevent tooth decay. You should make sure to brush after you eat and before you go to bed. Use a toothpaste that has fluoride each time you brush your teeth for the best protection against tooth decay.
