What are the factors that affect dental health?

1. Dentin allergy is manifested by eating some hot, cold, sweet and sour food, which makes his teeth extremely sensitive, and he has sharp pain and soreness. The reason is that the tooth tissue on the tooth surface is worn for a long time, which leads to the exposure of deep teeth closely related to the nerves in the mouth. Food stimulation is transmitted to the nerves along these channels, causing pain. Therefore, first of all, we should eat less food that is too irritating, secondly, we should use tools to eat food with too hard shells, and we should also get rid of the habit of brushing our teeth sideways. 2. Bad breath The mouth has a big breath or bad breath for a long time. If it is not caused by lung or stomach diseases, we should consider oral problems. First of all, tooth decay should be treated. After meals, you should floss your teeth. Occasionally, the gums are inflamed, and the teeth in the inflamed area should be flossed quickly. With proper medication, bad breath can be basically eliminated. 3. The tooth surface is dull and cracked. This is the expression of "tooth mineralization", which is the loss of enamel on the surface of teeth in oral acid environment, which will directly expose dentin to oral acid environment. In addition to brittle teeth, the surface of teeth will be discolored and dull. Young people need more careful maintenance and care in this situation. 4. Red and swollen gums bleeding teeth If the gums are red and swollen with bleeding, gingivitis can be judged. If you find bleeding when brushing your teeth or chewing food, you should also be vigilant. Gingivitis will develop into periodontitis if it is not treated in time. 5. Loose teeth If you touch your teeth while your gums are red, swollen and bleeding, or find that your roots are exposed, you can judge that you have suffered from periodontitis. Periodontitis is mostly due to poor oral hygiene and long-term accumulation of bacterial tartar, which will stimulate gums and cause inflammation. So pay attention to oral cleaning, brush your teeth in the morning and evening, rinse your mouth after meals, quit smoking and improve your oral environment. ?
