The tooth is hollow and black inside

Tooth decay is a common oral problem, especially among children. As we all know, human teeth are non-renewable. Once a tooth is empty due to tooth decay, the empty tooth will not grow again. Certain medical treatments are needed to make the teeth look normal. Below, we will introduce in detail the dangers, treatment methods and prevention methods of tooth decay.

1. Hazards

1. Harm of dental caries to adults

① It often causes inflammation of the root tip and other parts of the tooth. In severe cases, it causes local swelling. If pus and bacteria are absorbed, it may cause sepsis or bacteremia. ② Bad tooth roots make it impossible to chew food and increase the burden on the gastrointestinal tract. ③For the elderly, severe caries can cause most or all of their teeth to be lost, which is not conducive to their health.

2. 8 major hazards of dental caries in children

① Tooth defects involving multiple deciduous molars can reduce chewing function; ② Food residues are retained in caries cavities, bacteria accumulate, and oral hygiene deteriorates, affecting the occurrence of caries in permanent teeth; ③ Apical periodontitis of deciduous teeth affects the tooth germs that inherit permanent teeth, causing obstacles to their enamel development and normal eruption; ④ Premature loss of deciduous teeth due to caries causes the gap between permanent teeth to narrow, and positional abnormalities occur due to insufficient gaps; ⑤ The crowns of deciduous teeth that are damaged by caries are prone to damage local oral mucosal tissues; ⑥ Severe caries of deciduous teeth result in reduced chewing function, affecting children's nutritional intake and affecting growth and development; ⑦ Caries of deciduous teeth develop into apical periodontitis, which can serve as lesion teeth and cause lesion infections in other tissues of the body; ⑧ Affects aesthetics and correct pronunciation.

II. Treatment

1. Medication

Drug treatment is a method of using drugs to inhibit the development of caries on the basis of grinding away caries. It is suitable for shallow caries in permanent teeth that have not yet formed cavities, and shallow and medium caries cavities in deciduous front teeth. Commonly used drugs include silver nitrate and sodium fluoride.

2. Amalgam filling

For teeth that have already formed substantial defects, filling surgery is currently the most widely used and most effective method. The basic process can be divided into two steps: first remove the carious tissue and the weak tooth tissue that has lost its support, and then make the cavity into a reasonable shape according to certain requirements. Then it is filled with filling materials to restore its inherent shape and function. Suitable for filling cavities in back teeth and hidden areas of front teeth.

3. Composite resin filling

Suitable for filling front teeth and back tooth cavities that are not subjected to chewing forces.

4. Acid etching photosensitive composite resin filling

The indications are the same as those for composite resin filling, and it is also suitable for cases with many tooth defects, poor retention, and covering discolored teeth.

5. Inlay

A restoration made of metal or other materials that fits the tooth cavity and is embedded in the hole is called an inlay; the one that covers the occlusal surface is called a cap inlay. Applicable to: ① Those with larger cavities on the posterior occlusal surface or those with possible posterior teeth fracture; ② Those whose occlusal cavity fillings cannot restore the adjacent relationship with adjacent teeth; ③ As a semi-fixed bridge abutment.

3. Prevention

1. Brush your teeth in the morning and evening and develop a good habit of rinsing your mouth after meals;

2. Eat less acidic and stimulating food and do not eat snacks before going to bed;

3. Eat less foods high in sugar, such as sugar, chocolate, biscuits, etc.;

4. Do not eat too much hard food to avoid tooth wear;

5. Take part in physical exercise regularly and have regular oral examinations. Generally, people over 12 years old should have an oral examination once a year.

6. In daily diet, you should consume more nutritious foods rich in calcium, inorganic salts, etc., and eat high-fiber rough foods as much as possible.
