It is most prominent on the grooved chewing surfaces of back molars, just above the gum line on all teeth, and at the edges of fillings. Plaque and calculus irritate the gums, resulting in gingivitis . Acids begin to dissolve tooth enamel within 20 minutes after eating, the time when most bacterial activity occurs. Untreated tooth decay can result in death of the internal structures of the tooth with eventual loss of the tooth. The type of carbohydrate and the timing of ingestion are more important that the amount.
Sticky foods are more harmful than nonsticky foods because they remain on the surface of the teeth.
Frequent snacking increases the time that acids are in contact with the surface of the tooth. Oral hygiene is the primary prevention against dental caries. If possible, brush the teeth or rinse the mouth with water after eating these foods. Minimize snacking, which creates a constant supply of acid in the mouth. Avoid constant sipping of sugary drinks or frequent sucking on candy and mints.
