Why can't decayed teeth be filled?

In daily life, many people develop cavities because of failure to maintain good oral hygiene, improper brushing, and a love of eating sweets, candies, sour foods, spicy and heavy-tasting foods. Often, if it does not affect your life, you will not pay much attention to this matter. As a result, when the tooth is seriously damaged, the doctor may tell you that the decayed tooth cannot be repaired for the time being. The general reason is that the decayed tooth is too corroded and involves the tooth nerve. Anti-inflammation must be taken first, and then consider whether to repair the tooth or just pull out the decayed tooth.

If a tooth is decayed, can't you just fill it? Why can’t I make up for it?

In fact, it is very simple. Once tooth decay reaches the dental nerve, the nerve will be stimulated and infected, which will produce an inflammatory response. The pressure in the pulp cavity will increase, causing unbearable tooth pain. Once the filling is directly done, the bacteria inside the tooth will continue to develop, the internal caries will occur faster, and the pulp inflammation response will be more intense. Therefore, once the tooth nerve is decayed, we usually recommend killing the nerve or performing root canal treatment instead of directly filling the tooth.

So which teeth can be filled directly? Which teeth cannot be filled directly?

Shallow caries (early mild tooth decay): brown or black spots or plaques that appear on the teeth in the early stages. There is no conscious pain and it is difficult to detect it by yourself at this time. Usually a doctor needs to use tools to check and discover it. At this time, you just need to remove the decayed part and fill it.

Moderate caries: usually refers to caries that has decayed to the dentin, and the teeth will feel irritating pain when exposed to cold, heat, or sweet things. At this time, the development of caries is very fast and must be taken seriously. When the pulp cavity has not been penetrated, just clean it and fill it.

Deep caries: This is a severe late stage of tooth decay. Because it was not treated in time in the early and middle stages, the decayed part has developed to the dental nerve, and then the symptoms of pulpitis appear. At this time, it cannot be repaired directly. The nerve needs to be killed and root canal treatment needs to be performed.

If I want to fill a mild tooth decay, which material is the most cost-effective?

At present, these two types are more commonly used. Choose according to your tooth decay situation:

Glass ionomer is a filling material with good biocompatibility. It has better adhesion to tooth tissue and can protect the dental pulp while releasing fluoride to prevent further tooth decay. This material is more suitable for filling children's deciduous teeth that are decayed.

Composite resin is a filling material that is close to the color of teeth, has good adhesion, and is particularly wear-resistant and corrosion-resistant. Most importantly, no traces of the filling can be seen after the filling, so it is suitable for both young and old.
