I am curious if antibiotics become resistant to the a tooth infection then how can you get it extracted?

Depends: If the bacteria causing the infection have become resistant to a particular antibiotic, a different medication may solve the problem. Sometimes the best approach is to block a nerve away from the infection to get good local anesthesia in the area and get the tooth removed to eliminate the source of the infection.

Many teeth that: Have active infection are extracted ever day all over the us. Very serious tooth related infections are treated with antibiotic prior to removal by some dentists. In general, if swelling is significant and you have fever, you need meds. However, it is not an absolute requirement for there to be a completely controlled tooth related infection prior to extraction. Consult w your dentist in this.

Switch meds: If antibiotic is not working due to resistance, the med may be switched to another antibiotic or regiment. Some infections can be drained thru tooth or gums to lessen pressure or irrigated. The extraction can be performed though the numbing may not be as profound and post-op complications like delayed healing may persist.

Change & extract: In extreme cases of resistant bacterial infections , the treatment probably well be to change to broad spectrum antibiotics , along with the extractions while under the antibiotics treatment should also assist in irradiation of the infection by taking the source (the tooth) out.

If: You can culture the infection to find out what antibiotics will work best. Your doctor may just switch antibiotics. Are you asking this as a general question or are you experiencing this situation? If it is the latter, then ask your oral surgeon what he recommends. If you are band-aiding your needed extraction with antibiotics, it is not a good idea, as the infection will always come back.
