Hello, toothache. This kind of tooth fire is mostly liver water, and stomach fire is more common. You can use some drugs or foods that clear the liver and stomach. I suggest you use bitter gourd, wax gourd and soup for toothache. Spicy food, such as pepper, onion, mustard, green onion, garlic, etc. , should be avoided in diet. Because of their heat, it will stimulate the pulp and make it painful.

I hope I can help you, thank you!
