In brief: Most of the times

Cephalexin could be an appropriate choice for uncomplicated tooth infections, as it has good activity against streptococci that live in the mouth and cause these infections.
However, Cephalexin lacks anaerobic activity, and some tooth infections (particularly abscesses) can be caused by anaerobic bacteria. If you are taking Cephalexin and your symptoms are not improving, visit your dentist.

In brief: Cephalexin a cure??

Cephalexin or Keflex can work for a tooth infection.
It really depends on what type of bacteria are causing the infection? It may bring down the swelling and infection, but it is not a cure. You should see your dentist to see what is causing this infection. Remember that antibiotics also have an expiration date. If you are using old antibiotics, they may not work as well.
