Dentinal hypersensitivity: solutions exist!

The only contact of a cream against your teeth trigger you pain, acid eats gives you cold sweats. You have surely Dentinal hypersensitivity. No panic, solutions exist for the smile. Doctissimo is the point.

Dental hypersensitivity is a real problem. It is estimated that approximately 50% of patients consulting their dentist suffer. Women would be mainly affected, in a niche of age of 20 to 50 years, with a peak between 30 and 40. But how to prevent these headaches that interfere in the life of every day? The causes of dental hypersensitivity


Sensibility dentin ire First of all, a small point on the anatomy of our teeth. These consist of two parts: the Crown, the visible and the root, hidden under the gumline. Schematically, the Crown is composed of different layers: the enamel, dentin, and pulp containing vessels and nerves. Contrary to conventional wisdom, these fleeting pain have nothing to do with caries, and do not result from a lack of hygiene.

The first cause of the Dentinal hypersensitivity is the destruction of enamel. Dr. Christophe Lequart, surgeon dentist and editor of the publications of the UFSBD, explained as follows: “the dentin is crossed by canaliculated containing liquid that communicate between the inside and the outside of the tooth.” When the enamel is corrupt, contact with substances will cause dilatation or a retraction of the fluid in the canaliculated. “This active nerve endings, where the painful message”. Several events can alter the layer of enamel. The first: the brush in a horizontal direction, with a rigid brush. This type of washing eroding the tooth, making losing its protective properties. Too acidic foods can also generate small holes within the enamel see completely dissolve this protective layer, causing this type of phenomenon.

The second cause of the Dentinal hypersensitivity is the Gingival recession: “If the gum does not completely cover the tooth, then the dentine is found directly in contact with the substances” indicates the Dr. Lequart. In a phenomenon similar to the previous, the teeth become hypersensitive. The fight against the daily dental hypersensitivity

If you are hypersensitive, several solutions are available to you. At home, you can use toothpaste stamped “sensitive teeth”. They are obstructing the holes on the surface of dentine. Generally, these toothpastes pulp are chloride strontium or potassium salts: are these molecules which will play the role of “plugs” of the canaliculated. They require no prescription.

It may also involve some mineral baths of mouth to exposed dentin mineralization. Should review its methods of brushing teeth: forget horizontal brushing and do a roll “from red to white” movement. This allows to not irritate the gums and of damaging your teeth. These techniques are effective in the majority of cases. “But if, after two months of treatment, the disorders persist, is associated with a dental treatment” continues Dr. Lequart.

The treatment of hypersensitivity in cabinet

Several solutions exist. Always to butcher those Micros on dentin, the dentist may pass you a varnish area. The second technique is the use of product which “freeze” dentin proteins: this limits the phenomenon of dilation-shrinkage of painful influx. Finally, in the case of most important enamel loss, especially for nicks related to brushing, the preferred solution is the composite resin and so the partial reconstruction of the protective layer.

If all of these methods are ineffective, in the last instance, the dentist can suck you the offending tooth: more than nerves, so more pain. Where a retraction of the gingival is involved, can also propose a gingival graft. Here, the aim will be to make a small collection of gum to the ask, where the tooth needs to be better covered.

In all cases, if, as a large part of the French, you are Dentinal hypersensitivity, please speak with your dentist. He can advise you on a method adapted to your needs. That these small pain are more than a bad memory.
