Do your teeth hurt you when you drink your tea or when you eat a frozen sorbet? This may be a dental hypersensitivity.

This frequent condition is manifested by dental pain, which occurs in very special situations: with a food that is too hot or too cold, by rinsing the mouth or by brushing the teeth.

When the enamel covering, it is altered or the gingiva retracts (a gingival recession), dentin is no longer protected. Porosities (microholes) exist in the thickness of the dentine, and will communicate with the pulp of the tooth where the nerve and the blood vessels that irrigate the tooth are located. Also, at the slightest contact (brushing) or stimulus (hot or cold for example), the nerve endings are directly stimulated, and the pains appear.

To protect the enamel, it is necessary to avoid the consumption of acid foods or drinks because they gradually demineralize the teeth and increase the porosities, they become more friable. Avoid over-consumption of all acidic products, especially citrus fruits (lemon, grapefruit, orange …). Be careful also with light or not soft drinks, energy drinks and medicines with vitamin C and vinegar. Attention also to traumatic brushing, particularly supported with unsuitable brushes (hard or medium).

They act especially if you leave a slight lm on your teeth after brushing, on some very sensitive teeth do not hesitate to put on them a little toothpaste to let it act.
