When your toothpaste breaks, the best thing you can do is replace it

A reader writes, “I have been trying to fix a tooth for years, and had to replace the tooth in my car seat after I broke it in a car accident.

Since I have been out of the hospital for a while, I was looking for a new toothpaste to replace it.” 

What’s your toothpastes problem?

Do you have a more permanent problem?
