Should i call the doctor for more antibiotics or will they last in my system for the next 3 weeks?!

I have a tooth that is infected and needs to be pulled, so the dentist put me on antibiotics for the infection.. I called the oral surgeon last week and they can't take me until July 28th and i just finish taking my antibiotic yesterday i took them for 7 days and now my tooth feels better.. I know they can't take a tooth out if it is infected and i'm afraid it comes back before my appointment to pull the tooth.. If anyone knows how long anitibotics stay in your system or continue to help please let me know.. I really would not want to take more antibiotics because it gave me a yeast infection, but i don't want the tooth to get bad again..Health Question & Answer
