I have a bad root canal and over weekend got gum boil.  Swished my mouth out with pure vanilla extract and the boil seemed to pop and my gum was numb.  Went to endontist this morning and he prescribed clindamycin.  From everything that Ive read, this anibiotic has some serious side effects.  Is there an alternative?  I believe that the only reaction I got from penicyllum was a rash and tightness in throat and that was when I was child.  Remember taking tetracycline after that.  Should I call endontist for alternative?
Thanks for using Chat Doctor. Read your query. Antibiotics are usually prescribed after the doctor has evaluated the condition of your tooth and its associated structures along with the general health. Had you mentioned the side effect of penicillin to the endodontist? If you are worried and do not want to take the prescribed medicine, call your dentist office and change the prescription provided you give the proper medical reaction history. Hope this was useful. Thanks and regards.
