Tooth enamel is tough, harder even than skeletal bone. But even with good dental hygiene, the enamel protecting teeth may show signs of decay for many reasons, such as:
Too little saliva: Saliva helps repair the earliest stages of tooth decay. It supplies high levels of calcium and phosphate particles that enhance protection of the tooth’s enamel surface. In addition, saliva protects the mouth by washing away food and the sticky film of acid-producing plaque that can cling to teeth.
Because of saliva’s importance, dry mouth symptoms should be evaluated by a care provider. Dry mouth can be caused by medical conditions or their treatments. Dry mouth is a common side effect of many prescription and nonprescription medications, including some antidepressants and anti-anxiety medications, antihistamines, medications for high blood pressure, anti-diarrheals, muscle relaxants and medications for urinary incontinence and Parkinson’s disease.
Inadequate fluoride: This mineral is an important enamel ally that can make teeth stronger and can enhance saliva’s remineralizing, anti-decay properties. Most people get adequate fluoride exposure through drinking fluoridated water and brushing twice daily with fluoride toothpastes.
But people who drink primarily bottled or filtered water may not be getting adequate fluoride. Even with adequate fluoride, dry mouth can throw off the normal balance teeth need to stay healthy.
A dentist may recommend fluoride treatment to protect and strengthen tooth enamel. Fluoride can be applied two to four times a year. Another option is nonprescription fluoride rinses available in drugstores.
Helpful tips: limiting tooth enamel contact with acids that come from many foods and beverages are a good start. Examples include citrus fruits, tart candies, diet and regular sodas or sports drinks, fruit juices and wine.
