Caries and periodontal disease.

I think it’s two major concerns in the mouth.

In general

Periodontal disease is less common in the mouth, which is prone to tooth decay

Periodontal disease is common in the mouth, which is less likely to cause tooth decay

It seems.

It seems that the cause is that the caries bacteria and periodontal disease bacteria are in a rivalry with each other and the bacteria that have taken the hegemony move predominantly in the mouth.

For those who are cavities and confident in their mouth

You may want to take a periodontal disease check.
