Toothbrushes
A soft-bristled toothbrush can help prevent damage to your teeth and gums. Use a comfortable size and shape that reaches the surfaces of every tooth. Treat yourself to a new toothbrush every three to four months or sooner if the bristles become worn or frayed. Replace children's toothbrushes more often because they sometimes chew on their brushes, making them wear more quickly.


Teeth are protected by a hard layer of enamel but can become worn from improper brushing. To brush properly, place the brush at a 45-degree angle to the teeth and use a gentle back-and-forth motion. Remember to clean the back teeth, the tongue and inside teeth surfaces where plaque deposits are heavy.

Fluoride
Fluoride is a natural mineral that safely strengthens tooth enamel, the hard outer "shell" of the tooth. It stops cavities from forming and is found in many foods, community water supplies, toothpastes and some mouthwashes. Your dentist can tell you if you are getting enough, or whether a fluoride supplement in drops or tablet form should be taken. During the next dental visit, be sure to ask how much fluoride is right for you and your family.

Flossing
Flossing is very important to good oral care and should be done at least once a day. It removes plaque and food particles from under the gum-line and between teeth. Parents should start flossing their child's teeth when the sides of two teeth touch.

To floss, start behind the upper molars at one side of your mouth. Using about 18 inches of floss, wind most of the floss around each middle finger leaving an inch or two of floss to work with. Use your thumbs and index fingers to tighten the floss and slide it between your teeth. Take care not to snap it down on the gums.

Curve the floss around the tooth in a C-shape at the gum line and gently slide it up and down, making sure to floss beneath the gum line. Work around to the other side of your mouth and repeat on your lower teeth. Use clean sections as you floss the rest of your teeth.

Sealants
Pits and fissures in molars are difficult to clean because they are too narrow for toothbrush bristles and too deep for the normal flow of saliva wash to reach. Without protection, these back teeth are especially prone to cavities. Sealants protect them by sealing out decay.

A sealant is a plastic material applied to chewing surfaces and acts as a barrier that protects enamel from plaque and acids. Sealants are painted onto the tooth where they harden to protect against decay. They hold up very well under the normal force of chewing and usually last several years before another application is needed. Children and adults can benefit from having this protective coating applied to their teeth.
