Re: Dental Abscess: Failed Root Canal
The hardness with gradually go away. It may require a bit of time for the body to fully resolve it. Taking the FULL dose of antibiotic is very important. Not to do so will only "tickle" the bacteria, let them mutate, and then come back with a vengeance. The full dose will kill them all and the infection should then be gone.
Using warm salt water rinses (1/2 tsp to 8oz water) 4 or 5 times a day will also help with any residual swelling.
I'm so glad to hear that you are doing better. Good luck and Merry Christmas!
