Self-examination of dental health for dentine hypersensitivity.
First of all, judging dentin hypersensitivity from these three points.
1. When eating, you will feel tingling when you encounter hot, cold, sweet and sour;
2. The toothbrush will hurt when it touches the teeth;
3. When teeth come into contact with toothpicks and flossing objects, there will be severe pain.
Second, the causes of dentin hypersensitivity
1. cracked teeth are tiny cracks on the surface of the crown, which are not easy to be found. Cracked teeth are caused by internal factors such as tooth structure and excessive chewing force.
2. If the teeth suffer from dental caries, there is a feeling of soreness when brushing teeth, drinking hot water and chewing food, indicating that the dental caries have developed to a moderate depth. When the dental caries develop to a depth close to the pulp, the sensitive symptoms will be obvious.
3. Wedge defect of teeth
In daily life, incorrect brushing methods will cause mechanical damage to the neck position of teeth, resulting in defects and external stimuli, especially sensitive symptoms when the temperature difference between hot and cold changes.
4. periodontitis
In the middle and late stage of periodontitis, alveolar bone is absorbed, which leads to gingival atrophy and bare root surface. The root surface that loses its protective effect is prone to sensitive symptoms under the stimulation of cold and hot temperatures.
Third, how to prevent and care for dentin allergy?
1. Brush your teeth scientifically and clean your oral hygiene. Pap brushing is the mainstream scientific brushing method.
2. Reduce the intake of acidic food. Most of the components of enamel are inorganic substances, which are easily corroded by acid, so it is necessary to minimize the intake of acidic substances. If you don't brush your teeth immediately after eating acidic foods and drinks, it is recommended to brush your teeth after one hour.
3. Timely diagnosis and treatment of periodontal disease. Dentine hypersensitivity is just a symptom, and only by treating the cause can the occurrence of dentin hypersensitivity be reduced.
4. Appropriate use of desensitizing toothpaste. Toothpaste can contain ingredients to relieve dentin sensitivity, which is helpful to relieve the pain of sensitive teeth; It also helps to block dentinal tubules, enhance the tolerance of teeth to cold, hot, sour and sweet stimuli, and further effectively relieve tooth pain and sensitivity.
