Can the antibiotic cephalexin cure a tooth abscess?

No. Antibiotics can decrease the size of the infection and give you temporary pain relief, but you cannot cure the infection without treating the tooth with the appropriate dental procedure.
Cephalexin a cure?? The short answer to this question is no. The antibiotics will help get your tooth abcess under control. However, it will not cure the cause of your abcess. The Cephalexin will reduce the swelling and the amount of bacteria in the area, but will not cure your abcess. Once you go off the antibiotics, in a short time the abcess will most likely reoccur. See your dentist!
NO antibiotic will. and cephalexin is not exception. However, it will not fix the underlying problem. You will need to see a dentist for definitive diagnosis, x-ray and drainage.

The test takes 40 minutes and most patients are found to no longer have allergy. Read more...

If your taking an antibotic for a tooth abscess can it still spread to your neck and brain.

Not likely. The reason you are taking an antibiotic is to kill all of the bacteria causing your infection. So that should not happen. But all antibiotics are not effective against all infections. If your pain and swelling are increasing, this means the antibiotic you are taking is not working against your infection. Call your dentist asap and let them know this and the antibiotic will be changed. Read more...
