It is possible that there is a slight infection in the root left from having that particular tooth pulled. I would suggest putting about a teaspoon of coconut oil in your mouth and swishing for about a minute - spit, then rinse before putting your partial back in there. Coconut oil is a natural antibiotic and it could solve your problem.
I would be interested to know if it helps you.
Wishing you the best. P.S. Drinking the coconut oil won't hurt you...
a different tooth,not on the plate
