Filled teeth are broken again?
Many people have always thought that as long as the rotten teeth are filled, they can sit back and relax and eat and drink with peace of mind! However, the reality is often very cruel: the filled teeth have been used for 1~2 years, and they start to hurt again! What's the matter? Is it because the doctor didn't make up for it? Oral reminder to the doctor: Beware of secondary caries!
What is secondary caries?
According to dentists, secondary caries refers to a tooth that has already been filled, with new decay occurring at the edge or bottom of its filling material. Clinically, a change in the color of the tooth tissue around the filling material can be seen. Combined with oral x-rays, it can assist in assessing the cause and extent of secondary caries.
Causes of secondary caries
The material is not tightly filled
Dentists said that there are several main reasons for the formation of secondary caries, one is caused by poor material filling. This is because the edges of the filling material are fractured, the tooth tissue is broken, and the filling material shrinks and the edges are not sealed, which can lead to a gap between the tooth and the filling. If you don't pay attention to oral hygiene, it creates an opportunity for bacteria to grow, which can lead to secondary caries.

The cavities were not removed
The second factor in the formation of secondary caries is that the original cavities have not been removed, that is, because the original diseased tissue has not been removed and the filling is carried out, the cavities under the filling may still be in the original position, so the cavities continue to expand the lesion.
0 did not clean their teeth properly
The third factor in the formation of secondary caries is that the teeth are not cleaned properly, and many people do not brush their teeth and clean the adjacent surfaces of their teeth more carefully after filling their teeth. After a period of precipitation, bacteria will continue to attack our teeth, causing them to decay again.
Dentists remind: people with poor oral hygiene maintenance, children and people with high caries activity (a large number of caries) are prone to secondary caries!
What should I do if I find secondary caries?
The treatment for secondary caries is a refilling.
First of all, it is necessary to completely remove the previous filling, then remove the secondary decayed part, and then replace it again.
