It hurts to drink cold water, hot water and take a breath. What happened?

There are two reasons. First, tooth decay can only be treated by doctors. Will it get worse? Tooth allergies are getting more and more painful. Here are some simple ways to treat yourself:

1: Tooth chewing surface is allergic, so you can chew tea or walnut kernel.

2. Rubbing raw garlic on sensitive parts for 2 ~ 3 minutes can also play a certain desensitization role.

If you still feel uncomfortable, go to the hospital and let the doctor do desensitization treatment.
