1, reason
Commonly known as "inverted teeth." Due to excessive tooth wear or tooth decay (tooth decay), the outermost hard enamel (enamel) of teeth is destroyed, and the sensitive dentin in the inner layer is exposed. When gargling with cold water or eating cold, hot, sour, sweet and other foods, you will feel uncomfortable because the pulp nerve is stimulated.
Over time, there will be pulp congestion, which will develop into pulpitis, pulp necrosis, periapical periodontitis and other diseases, bringing great pain to patients.
2. Coping methods
Dentin allergy should be treated actively. First, special drugs or lasers can be used for desensitization. If teeth have decayed teeth or other defects, they need to be repaired in time. If the defect is large and the repair effect is not good, the full crown can be used for protection. If these methods can't solve the problem, we can finally inactivate part or all of the pulp and perform root canal therapy.
Extended data:
Methods of self-testing whether teeth are healthy:
1. Open your mouth in front of the mirror and observe whether there is food between your teeth and yellow tartar on your teeth.
2. Look for dental caries, black spots, calculus and pigmentation.
3. Tap the upper and lower teeth, or use a toothbrush to help observe whether the whole mouth teeth are stable and loose.
4. Feel each tooth with the tip of the tongue and check for missing, skewed, loose, sore and other problems.
5. Check the mouth for ulcers, peculiar smell or inexplicable swelling.
6. Observe the color of the gums to see if they are normal pink and there are no signs of redness.
7. When eating spicy, cold, sour, sweet and sour food and brushing your teeth with cold water, do your teeth feel sour, painful, soft and bleeding?
8. Swallow a mouthful of saliva and wait for another 30 seconds to feel whether the saliva secretion in the mouth is sufficient and whether there is a sense of dryness.
If you don't have the above problems, your teeth are healthy. If more than two items are not up to standard, we should pay attention to oral hygiene. If the three items are not up to standard, you need to see a doctor. ?
