How can bulimia and anorexia affect teeth?

Does bulimia and anorexia affect teeth? Changes and dental damage in many people with bulimia are often easy to recognize. Frequent vomiting can cause the salivary glands and tissues of the mouth to swell and the tongue to become dry, red and sore.

A bulimic person is characterized by forced vomiting after eating as a result of a sickly obsession to maintain an extremely low weight with the idea of following the rules of image of today’s society.

Frequent vomiting can erode the enamel of the teeth, especially on the tongue side of the upper front teeth. The acids of the vomit can develop into many consequences, the acid can destroy the protection of your teeth. After this happens many types of bacteria can perforate the surface of the tooth and reach the root, causing the tooth to fall or also called tooth decay. By this way, the chewing process becomes impossible, and this damage can only be saved or solved with dentures or implants.

The erosion of the teeth increases the risk of decay in these areas and can cause these teeth to become sensitive to temperature variations.
