I have a strong salt taste in my mouth after i had a emergency route canal done, but the taste is only on the one side of my tongue . please help?

Brush your tongue!: Your problem could be related to two situations: 1. If started to happen right after your root canal treatment, is very possible that some "liquid, medication, etc"spilled on your tongue and your taste papillae are reacting. Symptoms should disappear in a few days as you rinse frequently. 2. Injury to the lingual branch or nerve that runs by that area. Don't panic. Wait and see.

It might be: A coincidental feeling. I would consult back with your treating dentist. Hope this helps.
