“How long does it take for amoxicillin to work for tooth pain?”

If you have too much infection then you need time; otherwise, it will take a few times.

There are a number of causes of tooth pain. If your tooth pain is due to a bacterial infection such as an abscess, then it generally takes 24-48 hrs to start to feel improvement in symptoms.

Amoxicillin has no direct effect on dental pain. It's an antibiotic - a medical "marvel" which is a compound that when placed in the human body by mouth or injection enters the bloodstream and attaches itself to bacteria and inhibits (stops) the proper reproduction of these bacteria. This is the classical nature of antibiotics in general. So within 48 to 72 hours multitudes of bacteria are prevented from growing in your body and your immune system - primarily your white blood cells - can kill them off and your body recovers from the bacterial infection. Amoxicillin is the classic antibiotic for the successful destruction of bacteria causing dental infection. In conclusion, the pain you feel is from the effects of the bacterial infection. Once the Amoxicillin "does it's thing" then the pain disappears. So as a rule it takes 2 to 3 days for this to occur. There's no short-cut there unless you want an injectable form of Amoxicillin done in a hospital. That's why dentists normally give 2 to 3 days of pain medication to work until the Amoxicillin has had time to work.

3 to 4 days

Amoxicillin is an antibiotic that helps remove infection and bacterial growth. It is not a pain reliever. Once the antibiotic starts taking effect, the pain should also subside as the infection clears away. This normally takes 24 to 72 hours of regular dosing for symptoms to start to reduce.

Antibiotics generally take a couple of days to start working. They will kill the bacteria of an infection. However, they do NOT eliminate the CAUSE of the infection. So... your tooth might stop hurting - for a while, but unless the tooth is taken care of, the infection, and the pain, will come back. And, if the tooth is not taken care of, the bacteria that were not all totally eliminated will be more resistant to the antibiotics and it will be more difficult for antibiotics to work next time. So, please, take care of whatever it was that caused the toothache in the first place. Sometimes, a patient is too infected to do a root canal, an extraction, or a deep scaling. So they will be put on antibiotics for a few days to allow the antibiotic to start to get everything under control. The dentist can then go in and get the patient numb to take care of the problem. I will assume this is the case, in which case you're reading this after the fact. Good luck and feel better.

It usually takes 24-48 hours to start to feel the effects of an antibiotic.

Hello,

It usually takes anywhere from 24-72 hours. Usually for severe infections, you are instructed to take 2 pills immediately at the beginning, which is what we call a loading dose, in order to give your body a surge and to make the antibiotics more effective in a shorter period of time.

48 hours
