Fluoride has been shown to strengthen dental surfaces and reduce tooth fragility. In addition, it also helps to stop the progression of a carious lesion when it is in its initial stages, contributing to the deposition of new salts on the dental surfaces eroded by the action of acids. It is the most effective, safe and efficient means of reducing tooth decay. For this very reason, in many countries, water is deliberately fluoridated. The beneficial effect of fluoride is based on the "strengthening" of the tooth with fluoride during the development of the dentition, but also on the protection it offers later with the frequent contact of the teeth with it. The daily use of fluoride toothpaste is the most important factor in the effort to protect against tooth decay.
Dental fluoridation is an additional weapon to prevent tooth decay, especially in young children. Topical applications of fluoride are applied by the dentist 2 times a year.
