Is this medication right for a toothache?

Yes, this is right. Once the antibiotics get going you won't have anymore pain. The ibuprofen should work the best b/c it is such a good antiinflammatory. You can alternate extra stregth tylenol between the ibuprofen for more help. The antibiotics DO help with pain. Teeth actually do NOT have pain receptors. The pain comes from the pressure that builds from the infection building up around your tooth. Once, the infection goes down, you will feel much better. If it is horrible you can even double up the antibiotics and take 2 pills 3 times a day instead of 1, but you should check with your doc or dentist first to be sure. For bad infections, we often have people double up the antibiotics the first few days until it feels much better. Also, Cephalexin IS recommended for tooth infections. It often works much better on teeth bugs than Amoxicillin. This is what we normally prescribe. We do normally prescribe 500mg tabs 1, (3) times a day.
