Chemical Taste: You may have leakage of the sterilant under the temporary filling. This is not uncommon and usually passes in a day or so. If the root canal was recently finished, it may be the oil of cloves that's part of the cement used for the gutta percha. This should also pass in a day or so. Call your dentist for further guidance.

It's Unusual: A chemical taste and burning--with or without recent dental work--is unusual and should be checked. The dentist/endodontist who did the root canal treatment for you should be able to help you figure out what's going on. Give him/her a call right away, just in case your infection isn't responding to therapy as planned. It may also be unrelated to the recent treatment. In any case, don't wait.
