When I get up and brush my teeth with cold water, my teeth suddenly get sore. After eating a few plum, he found that his teeth were weak and sour and could not bite the food. Many of us may have experienced this experience. This is a symptom of dentine hypersensitivity -- a specific acidic, "soft," and painful condition that occurs when the exposed dentin of the tooth is mechanically, chemically, or stablically stimulated.
And the main prevention method, or in the formation of daily oral health habits.
What is the cause of dentine hypersensitivity?
1. Loss of tooth enamel
We know that the outermost layer of teeth is a dense structure called enamel, which protects the inner dentin and pulp from external stimuli. However, due to long-term wear, acid erosion, tooth defects, mechanical stimulation and other reasons lead to shallow enamel, abnormal structure, or even missing, resulting in dentin exposure, once mechanical, chemical, temperature stimulation, fragile dentin can not withstand, irritable to the pulp will produce uncomfortable symptoms.
2, the influence of systemic conditions
When the body is in some special conditions, such as women in the menstrual period and pregnancy, or when the body resistance decreases, the sensitivity of the nerve endings of the pulp will increase, so that some stimuli that are not enough to cause pain and discomfort can also cause dental allergy symptoms.
3. Factors of dentin structure
In contrast to the dense enamel layer, the structure of the dentin layer is relatively loose, and there are "dentin tubules". External stimulation can stimulate the deep pulp cavity through the hydrodynamic conduction in these small tubes, causing discomfort symptoms.
So how do we judge ourselves based on symptoms?
Dentine sensitivity is mainly manifested as pain, acid distension and weakness after stimulation. After the stimulation is removed, the discomfort symptoms will be immediately relieved or disappear, among which mechanical stimulation is the most significant. When judging, a probe or the tip of a sharp hard object can be used to find one or several sensitive points or sensitive areas on the tooth surface, which will trigger the corresponding discomfort symptoms. In general, sensitive sites are most common in the occlusal surface of the tooth and in the neck area of the tooth near the gums.
The formation of daily oral hygiene habits
The main prevention method, or in the formation of daily oral hygiene habits.
First of all, to prevent dentin allergy, we should brush our teeth correctly, choose a qualified toothbrush, use the correct brushing method, recommend the use of "Pap brushing method", avoid brushing too hard;
Reduce the intake of acidic foods and drinks;
After eating acidic food and drink, should immediately use normal temperature water gargle;
If you already have symptoms of tooth sensitivity, you can replace regular toothpaste with a professional anti-sensitivity toothpaste. It is soothing and sensitive at the same time, can meet the daily cleaning effect of the mouth. And good abrasive, low friction coefficient, prevent tooth sensitivity to continue to deteriorate, such as 2-4 weeks after no obvious effect, it should be timely medical treatment.
How to relieve the symptoms of dentine hypersensitivity in an emergency?
Allicin has anti-bacterial and anti-inflammatory effects and has certain effect in the treatment of dentin hypersensitivity.
Rough walnuts contain a lot of tannic acid, it can make the protein in the dentin tubule coagulation, can also play a role in desensitization;
You can also gently chew fresh tea leaves directly into the sensitive part of your teeth. Studies have shown that tea is rich in fluorine and tea polyphenols and other components, tea polyphenols have the effect of disinfection, sterilization, it can not only inhibit the growth of dental caries bacteria, but also enhance the acid-fast ability of tooth enamel, and in the presence of fluorine, acid-fast ability will be unexpectedly enhanced. In addition, the fluoride ion in tea has a very good health care effect on the teeth, it has a great affinity with the calcium of the teeth, which is like adding a protective layer to the teeth.
Clinical principles of treatment
Treat the corresponding dental disease and cover the exposed dentin.
Adjust excessively high tooth tips to reduce stress damage.
Desensitization treatment for sensitive sites.
Tooth sensitivity caused by systemic stress increase, in addition to local treatment, you can use traditional Chinese medicine conditioning program, or use other ways to improve the body immunity.
