Tooth enamel is the hard, external surface layer of your teeth that serves to secure against tooth decay. In fact, tooth enamel is viewed as the hardest mineral substance in your body, much stronger than bone. In spite of its strength, ordinary acids that develop from certain foods and beverages, especially those that are sweet or contain starch, can put your enamel in danger. Plaque microorganisms produce acids that can weaken and destroy tooth enamel. Acids can attack and soften the tooth surface.
Abrasion and Erosion are two types of damage to the teeth which can affect the tooth enamel. Abrasion is caused by something rubbing against the teeth. Brushing your teeth with a hard-bristled toothbrush, poking your teeth with toothpicks are possible causes of tooth enamel abrasion. Paradoxically, disintegration happens when the tooth polish is overexposed to dietary acids from specific foods and drinks, or acids in the stomach that are regurgitated. It also can be eroded due to the toxins that are released by the plaque bacteria that are around your gum line.
