Having sensitive teeth is not a disease; it is normal and has its reason for being. As in any other part of the body the pain warns us that something is wrong, sensitivity in the teeth helps us to react to any aggression that could harm them. For example, if you accidentally bite a stone that is in the food, the healthy tooth will send to the brain a signal to stop tighten the jaw and the tooth will not break signals, the odds of devitalized tooth in this situation would be much higher.
The problem is when the tooth sensitivity becomes a chronic nature and causes discomfort us in our day to day, that is when we talk about dental hypersensitivity .These complaints are derived from the exposure of dentin to chemical, thermal or tactile stimuli that are not associated with any type of dental pathology.
Causes of dental hypersensitivity
The principal cause of tooth hypersensitivity is the destruction of enamel, dentin is permeated by small tubes that connect the exterior and interior of a tooth and a nerve ending containing fibrils Thomes calls. When you lack the enamel are nerve fibres are much more exposed to any external stimulus and this is what causes discomfort features of hypersensitivity.
Another cause of dental hypersensitivity is receding gums, if the gum does not entirely cover the neck of the tooth, then the dentin is exposed to any stimulus as in the previous case.
In some people hypersensitivity is tolerable, while in others it is a problem that affects their quality of life, oral hygiene habits and even your diet.
The lack of attention to sensitive teeth can lead to other oral problems, this happens when the pain cannot brush your teeth, and therefore are more vulnerable to developing cavities and gum disease. By having this type of condition you should consult a dentist to tell us the most appropriate treatment.
For the treatment of hypersensitivity are using different products such as toothpastes, gels, mouthwashes and sprays. In general the most successful treatments are those that have in their composition of potassium salts, especially potassium nitrate.
It is also essential to take preventive measures to help prevent hypersensitivity and further enhance treatment. One is to employ proper brushing technique is not traumatic to the gum or grinding to the enamel, which avoids the wear of the tooth and therefore exposure of dentin.
Another preventive measure is to avoid the consumption of acids in foods and beverages in certain predisposed patients may erode the enamel (yogurt, fruit, juices and acidic drinks, etc..).
If despite all the above measures do not yield the inconvenience necessary to visit our dentist.
