Enamel dissolution is permanent, enamel doesn't regenerate itself once dissolved. When the enamel is worn away, the dentin underneath is exposed, which may lead to pain and sensitivity. Every time one eats or drinks anything acidic, tooth enamel becomes soft for a brief period of time and loses some of its mineral content. Saliva will slowly neutralize this acidity in the mouth and restore it to its natural balance. However, if this acid attack happens too often, the mouth does not have a chance to repair itself and tiny particles of enamel can be brushed away. Acidic foods and drinks such as soft drinks can be particularly harmful to teeth.

It is important to remember that even the diet brands are still as harmful. It is important to properly care for one's teeth to prevent tooth decay. Brushing one's teeth is the simplest means of preventing tooth decay. It is recommended that teeth be brushed in the morning, after every meal, and before one goes to bed. Fluoride is also often recommended to protect against tooth decay and using toothpaste with a good amount of fluoride is essential. Dental floss should also be used in addition to brushing.

It's important that you floss between your teeth at least once a day. Most cavities and gum disease start between your teeth, where your toothbrush just can't reach. Flossing removes the plaque from between the teeth and below the gum line. Some foods help to make teeth strong and healthy. Eating raw carrots, celery, and apples helps to clean teeth. Milk, cheese and yogurt contain calcium which is a component of teeth, and calcium intake helps maintain the integrity of teeth.

Regular visits, every six months, to a dentist are also very important.
