Causes of ulcers on gums

In fact, many people nowadays do not pay attention to their personal hygiene, especially now that there are many kinds of delicious food. In this case, you should pay more attention to your oral hygiene, otherwise it is very likely to cause ulcers on the gums. Let us now understand the causes of ulcers on the gums.

main reason:

1) Alkalinity of the environment

Saliva: Saliva contains soluble acidic calcium phosphate and acidic calcium carbonate. When saliva is secreted into the mouth, carbon dioxide escapes and the saliva becomes alkaline. The environment around plaque and soft scale becomes alkaline. When the pH rises, the soluble calcium salts become insoluble calcium salts and are deposited.

Bacteria: Bacteria in plaque and scale can decompose urea in saliva into ammonia, making saliva alkaline, increasing the pH and making calcium salts easily deposited.

2) Increased phosphatase: Normal gingival tissue contains phosphatase. During inflammation or trauma, the enzyme content increases. Dental plaque and desquamated epithelial cells can also release phosphatase, causing the deposition of phosphates in saliva. There is also a carbonic anhydrase that causes saliva to release carbon dioxide, promoting the deposition of insoluble calcium salts.

3) Escape of colloid protein: Saliva contains a colloid protein that can bind calcium and phosphorus ions, keeping the phosphate in the saliva in a supersaturated state. When the saliva stagnates on the tooth surface, the colloid settles, the supersaturated state cannot be maintained, and calcium phosphate is deposited.

4) Mineralized core: Mineral deposition must have a calcified core, and bacteria, epithelial cells and intercellular matrix in the plaque may become the main core materials. The matrix between plaque cells is mainly a proteoglycan complex, which can complex calcium salts from saliva to become calcification centers. The bacteria in the plaque are themselves a kind of matrix, such as Ciliate and Actinomycetes, which can form an organic scaffold and adsorb minerals and deposit them on the tooth surface.

The speed, shape and hardness of dental calculus formation vary from person to person. Generally speaking, new dental calculus needs

It takes twelve to fifteen hours. Rapidly formed tartar is softer and more fragmented than slowly formed tartar. All newly formed dental plaque is soft and will gradually harden after a period of calcification. Therefore, it is easy to remove dental tartar by using oral cleaning or brushing when it is just beginning to form, but it becomes difficult to remove once it has calcified.

The above article gives you a detailed introduction to the causes of ulcers on the gums. I believe you have a preliminary understanding of it, so in your daily life, you should pay special attention to your body hygiene.
