What to do if tooth decay bleeds when brushing? Timely treatment of tooth decay is the most important thing

The formation of tooth decay is related to many bad habits we usually have, such as not brushing teeth at night, not rinsing mouth after meals, often eating sweet foods, etc. The most important thing for tooth decay that causes bleeding when brushing is to treat tooth decay in time. You can use medication and pay attention to oral hygiene.

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 ammonium sulfate and sodium fluoride.

Treatment method: First, grind off the carious tissue as much as possible, and grind off the thin tooth slices at the edge of the hole to open the hole; use cotton strips to isolate saliva, wipe the tooth surface dry, and then use a small cotton ball dipped in ammonia silver nitrate solution to rub the carious tooth surface for 1-2 minutes, blow dry with a warm air gun and then apply again, do this twice, then use a small cotton ball dipped in clove oil to rub it to restore it to black, blow dry to complete the treatment. The reduced silver formed is precipitated in the dentinal tubules to block the dentinal tubules and prevent the development of caries. It is usually performed once a week, with 3-4 sessions as a course of treatment. Follow-up examination should be conducted after 3-6 months. Soft tissue burns should be avoided during treatment.

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.

(1) Basic principles of cavity preparation

Remove carious tissue and prevent secondary caries. One of the functions of cavity making is similar to debridement, which requires removing carious tissue so that the cavity can be established on healthy tooth tissue to prevent secondary infection.

Protect the pulp. The pulp is a living tissue with sensation and metabolism. Since the dentin and pulp are closely related, when cutting the tooth tissue, it will produce different degrees of stimulation to the pulp tissue. In severe cases, it can cause pulp congestion and inflammatory reaction. Therefore, attention should be paid to protecting the pulp during the operation. Prepare the resistance shape and retention shape.

Since teeth need to take on the chewing function after restoration, the filling and restoration should meet two requirements. On the one hand, it should be able to keep the restoration from loosening or falling off for a long time, that is, it should have a retention shape; on the other hand, the restoration and the remaining tooth tissue will not be broken due to the chewing force, that is, it should have a resistance shape. Both should be taken into consideration during cavity preparation.

3. Composite resin filling

Suitable for filling front teeth and back teeth cavities that do not bear chewing force. The key points of filling are:

①Prepare a certain hole shape

② Medium or larger cavities require a base

③ Mixing utensils should be clean and dry. Use a non-metallic mixing knife, pay attention to the ratio of the components, and mix thoroughly.

④ Prevent moisture during filling and avoid bubbles. Use polyester film or cellophane to press the material tightly, and finally shape and polish it.
