How to treat itchy teeth?

Do you mean your gums are itchy? Get some clove oil and rub on them. You can also use Anbesol, or Oragel. found in a drug store or online. There are different strengths. Anbesol Maximum strength https://www.walgreens.com/store/c/anbesol-maximum-strength-instant-pain-relief/ID=prod1464105-product

You could also talk to your dentist. An itch is actually a low form of pain.

Lastly, could it be due to medications you’re taking?

@snowberry I called a free nurse. He told me to drink cold water. It worked. He also wants me to see a dentist. I’m good for now. Will call in the morning.

Aloe?

I don’t think your teeth can be itchy @RedDeerGuy1 Like @snowberry asked, do you mean your gums?
