Dentinal hypersensitivity,more than a nuisance

Cold ice cream, heat broth or simply the pressure that makes the language on the surface of the teeth, are simple gestures that can be more than a nuisance when we suffer from tooth sensitivity, a painful syndrome that affects between 25 and 30% of adults.

Besides the obvious discomfort it generates in many people, it can lead to other dental by preventing perform proper oral hygiene problems and thereby cause caries and periodontal problems such as gingivitis.

Such sensitivity is from exposure of the inside of the tooth, the dentin to external stimuli of thermal origin, chemical or touch that can not be associated with any other dental pathology.

In healthy teeth, on the gum line is a layer of enamel that protects the tooth crown in its part exposed to view. On the underside, under the gum line, the protective layer is called cement, which is less hard than the enamel and protects the tooth root. Below both layers, enamel and cement, it would be located dentin. This softer and less dense than enamel and cement, tissue contains microscopic tubules (hollow channels) and consists mainly of hydroxyapatite crystals, collagen fibers and water.

When dentin enamel loses protection or cementum tubules more easily transmitted to the nerves within the tooth of external stimuli such as temperature changes, the acidity of food or drinks. Hence the dental hypersensitivity, which causes the painful sensation we all know arises.

Dentinal hypersensitivity

What can cause tooth sensitivity?

There are multiple causes, but the most common are the cavities, broken teeth, a worn tooth enamel, fillings shabby and gum disease left exposed tooth root.

There are also dental treatments that can temporarily cause tooth hypersensitivities, such as whitening or professional hygienes mouth, but such hypersensitivity should not worry too much because usually disappears.

When the annoying dental hypersensitivity appears necessary, therefore, to go to our dentist to assess what is the origin of the condition and conveniently try to avoid worsening.

The noninvasive treatment would be performed with an appropriate toothpaste, which contains compounds that help block the transmission of stimuli from the tooth surface to the nerve. They may also contain particles of nano-sized hydroxyapatite can seal the exposed dentinal tubules. Also, fluoride gels are used to strengthen the enamel and dentin.

In the event that there is a defect on the tooth surface or a cavity, the treatment would pass through a filling or a crown.

If the problem hypersensitivity is at the root of the gums, loss of tissue, the dentist may opt for a gum graft surgery. Or performing some filling on the exposed root surface. And if the problem of sensitivity is as persistent and severe, and the patient has not responded to any other treatment, you can opt for a root canal in extreme cases.

Regardless of the many causes that can cause dental hypersensitivity, proper oral hygiene with specific products remains the main preventive weapon to prevent this condition. Similarly, among the experts recommend preventive measures to avoid excessive drinking and acidic foods that wear the enamel and dentin, eliminate bad habits like cleaning teeth with toothpicks or bruxism (teeth grinding or clenching involuntarily) brushed and avoid aggressive and abrasive toothpaste.
