[Dental erosion and nutrition]

Abstract

Dental erosion is the chemical dissolution of tooth tissue by the attack of acids stemming from either the stomach or the diet. The organic acids produced by plaque bacteria are inducing dental caries. Risk factors for dental erosions are the frequent use of acidic foodstuffs (e.g. citrus fruits) and acidic drinks (e.g. cola's, fruit juices and sport drinks). As a risk factor from saliva has been detected: a low salivary secretory rate combined with a low pH and low buffer capacity. Prevention from dental erosion can be attained by 1. reducing the number of acidic moments during the day, 2. shortening the contact time and intensity in the oral cavity, 3. neutralizing a diet acid by drinking non-acidic milk (products), 4. regular fluoride application with a neutral gel and 5. pH-raising tablets e.g. bicarbonate- or urea-containing chewing gums, when the occlusal area is not eroded.
