Statistically, one in five German adults suffers from hypersensitive teeth.
Who does not know that, once inhaled cold air and already everything pulls together. An unpleasant, pulling pain that a sensitive tooth can trigger. The pain can sometimes be so great that even eating habits are restricted for fear of renewed irritation or even certain foods are avoided.
The cause can be an exposed tooth neck, which can be created in many different ways. As a result, the external protection of the tooth is lost in this area. Suddenly, stimuli such as heat, cold, sweetness or acid can cause pain to those affected.
Also, the mechanical contact with the toothbrush be very painful, whereby the oral hygiene is neglected precisely at these points.
Usually our teeth are perfectly protected by the enamel. However, if the gums go back, a very sensitive part of the tooth is exposed with a thinner enamel layer. This area has thousands of tiny channels, the so-called Dinkinkanälchen that lead directly to the pulp and thus to the nerve center. Stimuli such as temperature fluctuations or even pressure reach directly into the tooth via the dentinal tubules, where they can trigger pain.
The threshold for sensation of pain in heat at the enamel-dentin border is 47.7 ° C and is rarely reached in an intact tooth. The threshold for the sensation of cold pain, on the other hand, is 26.4 ° C, and is quickly undercut when eating ice cream. According to the hydrodynamic theory, the liquid (dentin cerebrospinal fluid) in the dentinal tubules (tubules) is set in motion by external stimuli when exposed to dentin, thereby irritating the fine nerve endings of the tooth nerve and triggering the sensitivity.
Other theories assume a direct irritation of the nerve endings by the acting substances. Furthermore, studies have shown that “sensitive” dentin has up to eight times more open dentinal tubules on the dentin surface than normal dentin.
Also, the diameter of the tubules is sometimes twice as large as in normal dentinal tubules, so that even mild stimuli cause an increase in the fluid flow in the tubules and thus triggering the pain.
Why does the gum disappear?
One of the most serious causes for the decline of the gums is a faulty cleaning behavior. Often the toothbrush is pressed too tightly and the teeth “scrubbed” with scrubbing, haphazard, even hectic cross and transverse movements. The protective gums are thus brushed further and further away and exposed to a strong mechanical friction for which it was not created. The consequences are injuries, the emergence of small wounds and a gradual decline of the gums, which exposes the necks of the teeth and makes the teeth sensitive to pain.
Another common cause of gum decline is gingivitis, called periodontal disease. If the inflammation is not treated, bacteria can penetrate ever deeper into the gums and at worst damage the anchorage of the tooth in the jaw. In the course of inflammation, the gums form back, the tooth neck and thus the dentinal tubules are then also free.
Other causes of sensitive teeth
Tooth enamel can also suffer massive damage due to incorrect brushing with too strong a toothbrush. These can then also lead to sensitive and pain-sensitive teeth.
Incorrect diet can lead to an ever thinner enamel layer. If the main acidic drinks and foods are consumed, then the enamel contained in them can attack the enamel. Over time, it becomes thinner and thinner until it finally decomposes completely and the tooth is no longer sufficiently protected.
The tooth suffers from a carious lesion. Caries bacteria attacked and partially destroyed the tooth enamel. External stimuli such as acids / sweetness penetrate into regions, which are then transmitted to the stimulus to the nerve.
An infestation of the tooth by caries is already so advanced that the nerve is already attacked. He reacts even with low stimuli, which would have no effect on a healthy tooth.
The patient suffers from bruxism, in which nocturnal gnashing of the teeth causes severe wear of the enamel. Also in this case, stimuli are transmitted to the nerve of the affected tooth.
The teeth and their chewing surfaces do not optimally fit the opposing teeth and thus experience an excessive mechanical stress that can irritate the nerve and cause sensitivities.
Fixed braces in children and adolescents, which are designed to correct the position of the teeth, can sometimes result in exposed tooth necks and jaw bones. Here, too, sensitive and pain-sensitive teeth can be the result.
That can change! Protect exposed dental necks with Dentcoat DS.
Depending on the findings, the dentist performs pre- and post-treatment with DENTCOAT DS to make the pain disappear completely and permanently.
After treatment with Dentcoat DS, you can also go back to the dentist without pain.
