Myths about Oral Health in Older Adults

Is dry mouth a natural part of the aging process? Is tooth decay just kid stuff? Separate fact from fiction by reading this web page about oral health and growing older. Having the right information can help you keep your mouth healthy for a lifetime.

Tooth Decay (Cavities)

Tooth decay is not just a problem for children. It can happen as long as you have natural teeth. Dental plaque – a sticky film of bacteria — can build up on teeth. Plaque produces acids that, over time, eat away at the tooth’s hard outer surface and create a cavity. Even teeth that already have fillings are at risk. Plaque can build up underneath a chipped filling and cause new decay. And if your gums have pulled away from the teeth (called gum recession), the exposed tooth roots are also vulnerable to decay. But you can protect your teeth against decay. Here’s how:
  • Use toothpaste that contains fluoride. Fluoride can prevent tooth decay and also heal early decay. And it is just as helpful for adults as it is for children. Be sure to brush twice daily. This will help remove dental plaque that forms on teeth. Drinking fluoridated water also helps prevent tooth decay in adults.
  • Floss regularly to remove plaque from between teeth. Or use a device such as a special brush or wooden or plastic pick recommended by a dental professional.
  • See your dentist for routine check-ups. If you are at a higher risk for tooth decay (for example, if you have a dry mouth because of medicines you take), your dentist or dental hygienist may give you a fluoride treatment such as a varnish or foam during the office visit. Or, the dentist may tell you to use a fluoride gel or mouth rinse at home.

Dry Mouth

Myth: Dry mouth is a natural part of the aging process. You just have to learn to live with it. Fact: Dry mouth is not a part of the aging process itself; it’s important to find the cause of dry mouth so you can get relief.
Dry mouth is the condition of not having enough saliva, or spit, to keep the mouth wet. Without enough saliva, chewing, eating, swallowing and even talking can be difficult. Dry mouth also increases the risk for tooth decay because saliva helps keep harmful germs that cause tooth decay and other oral infections in check. Saliva also contains minerals (calcium and phosphate) that can help reverse early decay. If you have dentures, dry mouth can make them uncomfortable and they may not fit as well. Without enough saliva, dentures can also rub against the gums and cause sore spots. It’s important to know that dry mouth is not part of the aging process itself. However, many older adults take medications that can dry out the mouth. And older adults are also more likely to have certain conditions that can lead to oral dryness. Here are some causes of dry mouth:
  • Side effects of medicines. Hundreds of medicines can cause the salivary glands to make less saliva. Medicines for high blood pressure and depression often cause dry mouth.
  • Disease. Some diseases affect the salivary glands. Sjögren’s Syndrome and HIV/AIDS can cause dry mouth.
  • Radiation therapy. The salivary glands can be damaged if they are exposed to radiation during cancer treatment.
  • Chemotherapy. Drugs used to treat cancer can make saliva thicker, causing the mouth to feel dry.
  • Nerve damage. Injury to the head or neck can damage the nerves that tell salivary glands to make saliva.
If you think you have dry mouth, see a dentist or physician. He or she can try to determine what is causing your dry mouth and what treatments might be helpful. For example, if dry mouth is caused by a medicine, your physician might change your medicine or adjust the dosage. Your dentist or physician also might suggest that you keep your mouth wet by using artificial saliva, sold in most drug stores/pharmacies. Some people benefit from sucking sugarless hard candy or chewing sugarless gum.

Oral (Mouth) Cancer

Myth: If you don’t use chewing tobacco, you don’t need to worry about oral cancer. Fact: It’s not just smokeless tobacco (“dip” and “chew”) that can increase your chances of getting oral cancer….
Tobacco use of any kind, including cigarette smoking, puts you at risk. Heavy alcohol use also increases your chances of developing the disease. And using tobacco plus alcohol poses a much greater risk than using either substance alone. The likelihood of oral cancer increases with age. Most people with these cancers are older than 55 when the cancer is found. Also, recent research has found that infection with the sexually transmitted human papillomavirus (HPV) has been linked to a subset of oral cancers. It’s important to catch oral cancer early – because treatment works best before the disease has spread. Pain is usually not an early symptom of the disease. So be on the lookout for any changes in your mouth, especially if you smoke or drink. If you have any of the following symptoms for more than two weeks, be sure to see a dentist or physician:
  • A sore, irritation, lump or thick patch in the mouth, lip, or throat
  • A white or red patch in the mouth
  • A feeling that something is caught in the throat
  • Difficulty chewing or swallowing
  • Difficulty moving the jaw or tongue
  • Numbness in the tongue or other areas of the mouth
  • Swelling of the jaw that causes dentures to fit poorly or become uncomfortable
  • Pain in one ear without hearing loss
Most often, these symptoms do not mean cancer. An infection or other problem can cause the same symptoms. But it’s important to get them checked out—because if it is cancer, it can be treated more successfully if it’s caught early.
