Teeth are meant to last a lifetime. By taking good care of your teeth and gums, you can protect them for years to come. Tooth decay is not just a problem for children. It can happen as long as you have natural teeth in your mouth.

Tooth decay ruins the enamel that covers and protects your teeth. When you don’t take good care of your mouth, bacteria can cling to your teeth and form a sticky, colorless film called dental plaque. This plaque can lead to tooth decay and cavities. Gum disease can also cause your teeth to decay.

Fluoride is just as helpful for adults as it is for children. Using a fluoride toothpaste and mouth rinse can help protect your teeth. If you have a problem with cavities, your dentist or dental hygienist may give you a fluoride treatment during the office visit. The dentist also may prescribe a fluoride gel or mouth rinse for you to use at home.

Gum diseases (sometimes called periodontal or gingival diseases) are infections that harm the gum and bone that hold teeth in place. When plaque stays on your teeth too long, it forms a hard, harmful covering, called tartar, that brushing doesn’t clean. The longer the plaque and tartar stay on your teeth, the more damage they cause. Your gums may become red, swollen, and bleed easily. This is called gingivitis.

If gingivitis is not treated, over time it can make your gums pull away from your teeth and form pockets that can get infected. This is called periodontitis. If not treated, this infection can ruin the bones, gums, and tissue that support your teeth. In time, it can cause loose teeth that your dentist may have to remove.

If brushing or flossing causes your gums to bleed or hurt your mouth, see your dentist.

Your dentist also may prescribe a bacteria-fighting mouth rinse to help control plaque and swollen gums. Use the mouth rinse in addition to careful daily brushing and flossing. Some people with arthritis or other conditions that limit motion may find it hard to hold a toothbrush. It may help to attach the toothbrush handle to your hand with a wide elastic band. Some people make the handle bigger by taping it to a sponge or Styrofoam ball. People with limited shoulder movement may find brushing easier if they attach a long piece of wood or plastic to the handle. Electric toothbrushes can be helpful.

Dentures may make your mouth less sensitive to hot foods and liquids. They also may make it harder for you to notice harmful objects such as bones, so be careful. During the first few weeks you have dentures, your dentist may want to see you often to make sure they fit. Over time, your mouth changes and your dentures may need to be replaced or adjusted. Be sure to let your dentist handle these adjustments.

Keep your dentures clean and free from food that can cause stains, bad breath, or swollen gums. Once a day, brush all surfaces with a denture care product. When you go to sleep, take your dentures out of your mouth and put them in water or a denture cleansing liquid.

Take care of partial dentures the same way. Because bacteria can collect under the clasps (clips) that hold partial dentures, be sure to carefully clean that area.
