Tooth decay is an illness: bacteria destroy the tooth’s structure. Enamel and dentine progressively deteriorate, thus producing dental cavities or holes in the teeth. If untreated, this illness can cause pain, tooth loss or infection. Depending on the severity and location of the affected areas, different dental treatments allow teeth to be re-established in their form, their function, and aesthetic ideals, namely white fillingscomposite veneersporcelain veneers, and porcelain crowns. Other measures can be useful, for example better eating habits and the application of fluoride lacquer by a professional. This is why numerous dental health organizations from around the world recommend preventive measures and prophylactics such as regular dental and oral hygiene and a change in diet in order to prevent tooth decay.
