Why does the hole in the tooth become bigger and bigger? Will there be secondary caries after filling the tooth?

Everyone knows that dental health is very important. People with cavities in their teeth need to go to the hospital to fill them in time. If they don’t, their teeth will become more and more serious. Let’s take a look at why the holes become bigger after filling.

In simple terms, a filling is when a doctor uses professional instruments to manually grind away the black (decayed) part of your tooth with a dental drill, and during the grinding process, the hole is made into a specific shape (the specific shape depends on the location and size of your decayed tooth, etc.). Finally, it is filled with filling materials. If it is deep decay that has damaged the dental nerve, it is necessary to kill the nerve, do root canal treatment, and then fill it with filling materials.

Regardless of the material of the filling, secondary caries cannot be completely avoided. The appearance of secondary caries means that the tooth will be restored again, which also means that the tooth cavity will be polished again. It would be strange if the cavity does not get bigger and bigger. When the microcrack environment is appropriate, cariogenic bacteria in saliva will grow, resulting in secondary caries. Especially after the restoration of incisors and molars, the proportion of secondary caries is very high.

The main source of odor in tooth decay cavities is because food is stuffed inside, and the food will produce some corrupt odors under the fermentation of some bacteria. In this case, if the cavity is not very deep, we can first grind the decayed part clean, and then fill it with artificial materials.

1. The cavity in a tooth will become bigger as it is filled.

2. When filling a tooth, the tooth was drilled so big, and it was repeated over and over again until the whole tooth was gone.

3. After the filling is completed, the filling material will fall off, and you will need to fill it again after a period of time, and then the hole will become bigger and bigger.
