How do dental caries develop?

Dental caries is a chronic disease, when most people in superficial caries, usually not how to treat, because this time there is no obvious pain, but in fact, this is not desirable, because will continue to develop. So what exactly is the formation of dental caries? In adolescents, dental caries is a kind of disease, but also teenagers to bring some pain, so after the occurrence of dental caries will appear in what situation? Let us look down.
The cause of dental caries is the result of the influence of various internal and external factors. In recent years, with the development of medicine, the etiology of dental caries has been further explained. It is believed that dental caries is caused by the coexistence of three factors, namely bacteria, carbohydrate, food and the anti caries ability of teeth.
The role of oral bacteria. Streptococcus mutans and lactic acid bacteria in the mouth reproduce on food residues remaining in the mouth, which ferment and produce acid, which causes the teeth to corrode, soften, and decalcification. When the tooth is decalcified, it gradually forms a cavity.
Sugar is a necessary condition for dental caries. Carbohydrates play a decisive role in the development of dental caries. Especially, foods containing sucrose can increase the number of plaque on the tooth surface and increase the number of cariogenic streptococci.
The body's resistance to caries has a significant impact. The body's resistance includes the teeth and the body's anti caries ability, the body's internal factors can affect the occurrence of dental caries. Especially when the protein, minerals and vitamins are scarce, it can help the occurrence of dental caries.
The morphology, structure, location, oral hygiene, quantity and nature of saliva, nutrition, endocrine, genetic factors, systemic diseases, immune status and so on all affect the occurrence and development of dental caries. The teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, and teeth. Saliva viscosity, quantity, oral health, endocrine disorders, malnutrition, tuberculosis and other systemic diseases, trace elements deficiency are related to the occurrence of dental caries.
After the tooth decay occurs, there is no uncomfortable feeling at the beginning, only a small hole in the tooth. When the decayed tooth grows deeper and close to the sensory nerve endings of the pulp, the cold, hot, sour, sweet food is sore. Serious when can cause pulpitis or root inflammation caused by severe pain.
Generally speaking, the following hazards exist:
1. when the caries destroys the enamel and invades the dentin, the patient feels pain when it meets cold, heat, acid and sweet stimulation. The clinical examination shows that the cavity is formed on the tooth and is dark brown. In this stage, if untreated, the decay will gradually increase the pulp, caused by pulpitis, then there may be spontaneous pain, can also cause ipsilateral headache, restlessness patients. If not treated, the inflammation continues to develop to the root direction caused by periapical root swelling, pain, loose teeth, bite periodontal pus, severe facial swelling, have a fever, trismus, bacteria into the blood can cause bacteremia and even life-threatening.
2. dental caries is not treated in time, can be gradually developed severe periapical, will cause dysplasia, if due to caries early loss of deciduous teeth and permanent teeth will not only affect the schedule that will lead to the adorable, permanent teeth arranged in disorder, caused by malocclusion.
Permanent teeth due to caries early loss, missing teeth number, will affect the chew food, will increase the burden on the stomach, causing gastrointestinal disease.
1., serious caries caused by crown, residual roots, stimulate the surrounding soft tissue, causing ulcers, erosions, and even cancer. Can also become a focus of bacteria, the base camp.
2., the toxin of bacteria can flow to all parts of the body. Data show: caries lesions can cause iris, ciliary body inflammation, rheumatoid arthritis, nephritis, rheumatic heart disease or viral myocarditis, systemic pain and so on.
So, to prevent the occurrence of dental caries, which items should be paid attention to?

First of all, we should pay attention to oral hygiene, learn the correct way to brush teeth, and develop good habits sooner or later brushing teeth and mouthwash after meals. Toothbrush can use health toothbrush and fluoride toothpaste. Trace elements of fluoride can resist the acid corrosion of teeth.
Secondly, do not eat too much sugar, but also pay attention to nutritional supplements and physical exercise, in order to enhance the ability of disease resistant bacteria invasion.
Finally, it should also be noted that routine oral examinations should be conducted regularly so as to detect dental caries in time and to repair it as soon as possible.
The correct way is: the toothbrush should be along the long axis of the tooth vertical brush, the brush on the teeth from the top down brush, brush teeth from the bottom up under the brush, brush on the occlusal surface, press the bristles on the teeth, brush back and forth, brush the outside brush inside.
The above description has a very detailed, we believe that the friends of patients should have a more profound understanding, for it is not against dental caries, a short duration of time things, at the same time, the formation of dental caries is not a short duration of time, in daily life, always pay attention to, take good care of their teeth, because no one think so early and some nice to say goodbye.
