There are about 540,000 small holes in a bare tooth called small dentin tubules. Healthy teeth have a layer of enamel that protects the dentin. It is smooth and hard. If you don't pay attention to protection, even the hardest organs of the human body, bacteria will enter the teeth through the dentinal tubules, causing many health hazards. So what are the common oral problems?
1 tooth stone
The calculus is commonly called "tooth rust", which is calcified plaque and oral cell debris. The calculus is often produced in the armpits and the like, which can irritate the gum tissue and cause gingivitis. After the calculus is formed, it is easily stained by smoke, tea, etc., which greatly affects the aesthetics of the mouth.
2 gum problems
The main manifestations of the gum problem are redness of the gums, bleeding of the gums, and the like.
The metabolism of bacteria in the mouth produces acid, which can erode the hard enamel and develop into a dental caries. It is a disease in which the hard tissues of the teeth are gradually destroyed. The onset begins in the crown. If it is not treated in time, the lesion continues to develop, forming a cavity, and the crown completely disappears. Untreated cavities do not heal by themselves, and the end result of their development is tooth loss.
4 sensitive teeth
Sensitive teeth are tooth pain caused by wear on the tooth surface or gum tissue. The most common cause of adult tooth sensitivity is the decay of the gums leading to root exposure. Because the roots lose the protection of the enamel, thousands of tiny holes appear in the teeth, exposing the nerve center of the teeth (the pulp). At this time, encounter cold, acid, sweet and other external stimuli, the stimulation will be quickly transmitted to the pulp through the dentinal tubules, causing a sore feeling.
5 tone problem
Bad breath is mainly caused by oral bacteria, which break down food amino acids and produce volatile sulfur-containing gases. Breaths can be caused by poor oral hygiene, periodontal disease, dry mouth, smoking, illness, or eating certain foods.
6 tooth stains
Tooth stains, also known as tartar, are stains attached to the surface of the teeth, mainly exogenous pigmentation, usually caused by the habits of everyday life.
Plaque refers to a population of microorganisms that adhere to the surface of the teeth or other soft tissues of the mouth. It is composed of a large number of bacteria, intercellular substances, a small amount of white blood cells, exfoliated epithelial cells and food debris. Do not remove it with a mouthwash or rinse with water. Therefore, plaque is now regarded as a complex ecological structure in which bacteria adhere to tartar, which is closely related to the occurrence of rickets and periodontal disease.
