Have your teeth ever been soured?

Since the beginning of autumn, the heat has gradually subsided. The autumn wind has brought a hint of coolness, and the long-sleeved clothes in the closet have been taken out one after another to resist the gradually cold weather. Unexpectedly, the cold wind blew into the mouth, and the teeth felt sour and astringent, and goose bumps appeared all over the body. It takes courage to brush teeth and rinse mouth with cold water in the morning. Where does this annoying sourness come from? Let's talk about it today.

This phenomenon of short-term, sharp pain or discomfort that occurs when teeth are stimulated by hot or cold, sour or sweet, or friction is clinically called dentin hypersensitivity. It is a common oral clinical symptom that often occurs in premolars, which are the fourth and fifth teeth. About 40-50% of people suffer from this disease.

The mechanism of dentin sensitivity is that when the dentin is exposed to the external environment, cold, heat, sweetness, sourness, mechanical stimulation, etc. are transmitted to the pulp, stimulating nerve fibers and causing pain.

The factors that cause dentin sensitivity mainly include wear, abrasion, acid erosion, gingival recession and the use of bleaching agents.

Improper oral hygiene measures, such as brushing too hard, using a toothbrush with hard bristles, brushing too frequently, brushing for too long, brushing immediately after eating acidic foods, or using toothpaste with a high friction value, may increase tooth wear.

1. Tooth wear. Abnormal occlusion, bruxism and other conditions will aggravate tooth wear.

2 Tooth wear Eating acidic foods, drinks, and medicines, working in an acidic environment, and gastroesophageal reflux can cause acid erosion on teeth.

3 Tooth erosion and gum recession expose the cementum and make it easy to wear, which may lead to further exposure of the dentin.

4 Gum recession bleaching agent is a chemical substance that causes dentin sensitivity. Bleaching can easily cause dehydration of tooth tissue, leading to persistent symptoms of dentin sensitivity.

5. Use bleaching agents. In addition, if the teeth suffer from diseases such as caries, periodontal disease, cracked teeth and dental trauma, symptoms of tooth sensitivity to cold, hot, sour and sweet substances may also occur.

How can I prevent tooth sensitivity?

1. Choose a soft toothbrush with blunt bristles, use the correct brushing method (Bass method), and use fluoride toothpaste or anti-sensitive toothpaste with low friction value for daily brushing;

2. Timely diagnosis and treatment of dental caries, periodontal disease, bruxism, excessive tooth wear, dental trauma, tooth cracks and other related diseases;

3. Reduce the intake of acidic foods and beverages;

4. Rinse your mouth promptly after eating acidic food or drinks, and brush your teeth at least 1 hour later;

5. Patients with symptoms such as gastroesophageal reflux and acid reflux are advised to treat systemic diseases;

6. Use tooth whitening products with caution under the guidance of a doctor. Tooth sensitivity usually cannot heal itself. If tooth sensitivity is not treated in time, it will harm oral health. Once it occurs, you should go to a professional dental hospital for treatment in time.

Treatments for tooth sensitivity
1. Home Care

Brushing your teeth with anti-sensitive toothpaste is the first choice for alleviating dentin sensitivity. Use it twice a day for 4 to 8 weeks, which can greatly alleviate dentin sensitivity. If you cannot use toothpaste, you can use a mouthwash containing anti-sensitive ingredients, but the efficacy is uncertain. Effective anti-sensitive ingredients in anti-sensitive toothpaste/mouthwash include potassium salt products, stannous fluoride, calcium complexes, bioactive glass, strontium acetate, etc. When you buy it, you can check whether the product ingredients of the toothpaste/mouthwash contain the above materials.

2. Professional intervention

If symptoms are not relieved after 2-4 weeks of home care, professional intervention can be performed. Non-invasive or minimally invasive treatments such as local drug desensitization and laser treatment can be performed. If symptoms are not relieved after 2-4 weeks of treatment, resin filling, endodontic treatment or crown restoration can be considered to eliminate symptoms.
