Dental erosion is a loss of enamel or dentin. It is a result of an acid or a mechanical attack of the hard tissues of the tooth.
The causes are numerous (sodas, coca cola and others, bad brushing technique or use of a hard toothbrush for example).
The patient perceives the erosions as a sharp pain resembling the pain provoked by caries.
Certain chocolates are known to trigger this pain.
The treatment will depend on the cause but it generally consists of applying fluorides and desensitizing gels. A laser treatment can also ease the pain.
Certain toothpastes also have a desensitizing effect. Ask your dentist or hygienist.
The sensitivity is sometimes linked to stress or to the flu, and it often recurs.
