What causes gum decay?

The main causes of gum ulceration are local stimulation factors, poor oral hygiene, malnutrition, systemic diseases, drug factors, abnormal immune function, infection factors, etc. 1. Local stimulation factors Poor restoration, sharp cusps, dental calculus and other long-term stimulation of gums, easy to lead to local damage to gums, and then cause ulceration. For example, the edge of the bad restoration is not smooth, it will continue to stimulate the gingival tissue, so that it appears inflammatory reaction, if not treated in time, inflammation may lead to ulceration.2. Poor oral hygiene daily do not pay attention to oral hygiene, dental plaque, food residue, etc. accumulate in the gums, creating conditions for bacterial breeding. These bacteria can cause gum inflammation, inflammation to a certain extent may cause gum ulceration.3. Malnutrition lack of vitamin C, vitamin B and other nutrients, will affect the normal metabolism and repair ability of gum tissue, so that gums become fragile, prone to ulceration. 4. Systemic diseases Some systemic diseases such as diabetes, etc., will reduce the body's resistance, but also easy to induce gum ulceration. Diabetes patients due to poor blood sugar control, its periodontal tissue microvascular lesions, affecting the nutrient supply and resistance of the gums, resulting in gums more vulnerable to damage and infection and ulceration. 5. Drug factors Some drugs may cause gingival hyperplasia, and the hyperplastic gums are easily stimulated and ulcerated. 6. Abnormal immune function When the immune function of the body is disturbed, it may also lead to abnormal immune response in the gums, causing symptoms such as ulceration. 7. Infection factors Virus, bacteria, fungi and other infections may also lead to gum ulceration, such as herpes simplex virus infection can cause gum blisters, ulceration and other manifestations.
