(Concern) Chaa is crying.

These days, my teeth often feel sensitive.

I received cavity treatment and a scaling at the dentist...

I heard that microcracks can form in teeth, so I received treatment again on the area I had previously treated. Now that I am in my 50s, I wonder if this is a natural phenomenon...

I changed my toothpaste, but I'm not sure if it's very effective. I don't smoke, but I do drink alcohol occasionally.

I'm wondering if I should also take supplements related to dental health.
