Can brushing teeth remove dental calculus? thank you

Brushing your teeth can't remove dental calculus, but you can only solve this problem by washing your teeth. If calculus has formed, it is recommended to go to the hospital to wash your teeth early to avoid gingivitis or more serious diseases.

Dental calculus usually exists on the tooth surface at the opening of salivary gland (such as the lingual surface of mandibular anterior teeth and the buccal surface of maxillary posterior teeth) and the tooth neck, as well as the tooth surface where oral mucosa can not move. Dental calculus is soft at first, and will harden due to gradual calcification. It consists of 75% calcium phosphate, 15-25% water, organic matter, manganese phosphate, calcium inorganic acid and trace amounts of potassium, sodium and iron. Appears yellow, brown or black.

There are several reasons for its formation:

1. With the decrease of carbon dioxide concentration in saliva, inorganic salts are deposited on the tooth surface.

Second, it is formed because the phosphatase of degraded cells hydrolyzes organophosphorus to produce phosphorus precipitation on the tooth surface.

Thirdly, bacteria make saliva alkaline because of the increase of pH value, which leads to the decomposition of protein in saliva, releasing calcium salt and depositing it on the surface of teeth.

Fourth, it is related to the concentration of saliva. The higher the concentration, the easier it is to precipitate.

The speed, shape and hardness of calculus formation vary from person to person. Generally speaking, it takes 12 to 15 hours for new dental calculus to form. The rapidly formed dental calculus is softer and more broken than the slowly formed dental calculus. All newly formed dental calculus is soft and will gradually harden after a period of calcification. Therefore, in the early stage of dental calculus formation, it is easy to remove dental calculus by oral cleaning or brushing teeth, and it is not easy to remove it after calcification.

Dental calculus is a foreign body in the oral cavity, which will constantly stimulate periodontal tissue, oppress gums, affect blood circulation, cause bacterial infection of periodontal tissue, cause inflammation and atrophy of gums, and form periodontal pockets. When periodontal pocket is formed, food residues, dental plaque and dental calculus are more likely to accumulate, and this new accumulation will further destroy the deeper periodontal membrane. The result of this continuous vicious circle is that the periodontal supporting tissue is completely destroyed, and the teeth can't escape the bad luck of tooth extraction.
