1. What is gingival atrophy?

The gingival margin retreats to the root, which leads to symptoms such as root exposure, dentin hypersensitivity, gingival bleeding, and even tooth loss.

Second, the symptoms of gingival atrophy?

1, "black triangle"

Visible to the naked eye, the teeth become longer, the gap between teeth becomes larger, the roots are exposed, and the whole teeth or individual teeth are out of line "from red to less black triangle" phenomenon.

2. Dentin allergy

Teeth are sensitive to cold, hot, sour and sweet foods. When brushing teeth and biting hard objects, the teeth will have temporary stinging and wedge-shaped defects will appear to varying degrees.

3. Dental caries

When gingival retraction occurs, the seam becomes larger first, which is easy to cause food impaction and adjacent caries. Excessive root exposure can also lead to root caries.

Third, the cause of gingival atrophy?

1, periodontal disease

Periodontal disease is one of the important causes of gingival atrophy. If not treated in time, periodontal abscess will recur, teeth will become loose, the gap between teeth will become bigger and thinner, and even teeth will fall off seriously.

2. The brushing method is incorrect.

If you brush your teeth with a saw, the bristles of the toothbrush are too hard and the brushing force is too strong, which will destroy the teeth and periodontal tissue.

3. Excessive orthodontic force

If the corrective force is too large and the teeth move too fast, it is easy to cause gingival atrophy, so the correction is not required to be fast.

Step 4 Grow with age

With the increase of age, the height of gum will decrease at the rate of 0,065,438+0.2 mm per year, which is one of the reasons why adult orthodontics is more likely to produce "black triangle" than teenagers.

5. Occlusal trauma

Abnormal bite force will cause trauma to gingiva and periodontal tissue, leading to gingival recession.

Fourth, how to prevent gingival atrophy?

1, brush your teeth correctly

Use a soft toothbrush and a brush head that fits your mouth. Brush your teeth with Pap method 2-3 times a day. At the same time, get into the habit of flossing and clean the hard-to-reach position of toothbrush.

Step 2 clean your teeth regularly

Wash your teeth every 6- 12 months to remove calculus and stains and keep your gums healthy. Patients who have used periodontal symptoms should receive systematic periodontal treatment in time.

3, don't covet cheap and convenient.

It is necessary to ensure that improper handling in standardized dental clinics or hospitals may easily lead to subsequent oral hazards and gingival atrophy.

If you find any abnormality, you should seek medical advice as soon as possible.

If you feel that some teeth move abnormally, you should go to the hospital in time for examination, early detection and early treatment to avoid gingival atrophy.
