16Taking Care of your Teeth and Gums Brush your teeth after eatingFloss between your teethUse a soft-bristled toothbrush and toothpaste that contains flouride.Reserve starchy foods and foods high in sugar for mealtimes.Have regular dental checkups.
17Dental ProblemsEveryone-including you-has bacteria in his or her mouth. These bacteria make a sticky substance calles plaque, which coats your teeth. When the bacteria in plaque break down sugars in the foods you eat, acids form. These acids make holes, called cavities, in your tooth enamel.If a cavity isn´t treated, the hole spreads through the dentin to the pulp and then to the damaged portion of the tooth. The dentist then fills the hole with a hard material, and the tooth is saved.Plaque can cause other problems, too. If plaque is allowed to remain on the teeth, it forms a hardened material. This material can cause gengivitis, a gum disease in which the gums become red and swollen.
19OrthodontiaSome people wear braces, usually for several years, to straighten teeth. After the braces are removed, a person may wear another dental appliance, called a retainer. The retainer keeps the teeth from moving out of place.
20The straightening of crooked teeth is called orthodontia. Straightening teeth makes them easier to clean and helps:Prevent cavities and gum diseases.Prevent uneven wear of the teeth.Ensure that your teeth will last a lifetime.
