1. Tooth sensitivity and easy to ignore dental problems
Tooth sensitivity, commonly known as "inverted teeth", and the scientific name is "dentin sensitivity", which refers to:Short, sharp pain from exposed dentin in response to external stimuli, this pain cannot be attributed to any other form of dental defect or disease, typical irritation includes:Temperature stimulation, insufflation stimulation, mechanical stimulation, osmotic stimulation, and chemical stimulation
Therefore, if dentin is exposed, whether you are eating a steaming hot pot or enjoying the beautiful snow scene outside, between hot and cold stimulation, it is easy to develop tooth sensitivity.
In addition, due toDentin sensitivity is an episodic, temporary painFor example, when we go to a dental institution, if we do not have symptoms of dentin sensitivity at that time, we may not mention it to the dentist in time.
2. A variety of factors can lead to tooth sensitivity
Dentin sensitivity occurs as a result of a single cause or a combination of causes. The main points are as follows:
Abrasion
Mainly incorrect oral hygiene measures such as:Excessive brushing force, use of a toothbrush with hard bristles, frequent brushing or extended brushing time, etcIt has an important relationship with dentin sensitivity;Brush your teeth immediately after eating acidic foods and drinks, which may remove hard tissue from the tooth surface that has been demineralized and softened;useToothpaste with high friction valueIt can aggravate the wear and tear of tooth enamel and dentin.
Abrasion
Tooth abrasion includes:Abnormal occlusion, bruxismWait.
Etching
Etching includes:Exogenous acids and endogenous acids。Exogenous acids are mainly used in acidic foods, beverages, drugs (such as vitamin C, aspirin) and working environments (such as battery industrial workshops, swimming pools disinfected with chlorine preparations, etc.).Endogenous acid** in the case of gastroesophageal reflux, pregnancy reaction, etc.
Gum recession
After gingival recession, the cementum is exposed and easily abrasive, leading to further exposure of dentin. Some dental diseases such as congenital anatomical defects, plaque build-up on the root surface, periodontal disease and improper periodontal disease**, orthodontics**, etc., can cause gum recession.
Use bleach
Bleach is a chemical that causes dentin sensitivityBleaching can easily cause dehydration of tooth tissue, resulting in persistent symptoms of dentin sensitivity
3. The "cheats" of dental care for people with sensitive teeth
The main causes of dentin sensitivity include:Home care and professional interventions。In home care,Brushing with anti-sensitive toothpastes is the preferred method for relieving dentin sensitivity, such as daily use of anti-sensitive toothpastes that contain ingredients such as strontium acetate, bioactive glass (novamin), potassium salts, or stannous fluoride, used 2 times a day for 4 to 8 weeks, can greatly relieve dentin sensitivity.
In daily home care, in addition to using anti-sensitive toothpaste, people with tooth sensitivity should also pay attention to the following:
Choose a toothbrush with round, blunt bristles and the correct brushing technique
If there are periodontal disease, bruxism, excessive tooth wear and tear and other related diseases, it is necessary to ** as soon as possible
Reduce your intake of acidic foods and beverages;If you rinse your mouth after eating, brush your teeth at least 1 hour later
Use teeth bleaching products sparingly.
WhileIf the symptoms are not relieved after 2 to 4 weeks of home care, you should choose to receive a professional ** in a regular dental institutionAt present, commonly used methods such as local drug desensitization, laser, etc.
It is important to note that tooth sensitivity does not only occur in winter, but can also occur in other seasons, soIt's important to stick to the correct brushing attitude and method on a daily basis, as is using an anti-allergy toothpaste to relieve symptoms, so that your teeth may not be so sensitive!
