If you have a gum or tooth infection, you want relief fast. And you may be thinking an antibiotic is the way to go.

As with most medical issues, however, the answer isn’t always that clear-cut. There are a handful of things you’ll want to consider and discuss with your doctor (and a dentist) before you try a prescription antibiotic.

Here are some insights from our network of 90,000+ doctors.

Antibiotics alone won’t cure a tooth infection

“The source of the infection has to be removed,” says Dr. Daniel Sampson. “This involves removing decay, sometimes a root canal or periodontal cleaning, or an extraction.”

For this reason, it’s best to see your dentist, or, if you’re waiting on an appointment, talk about your options with your Primary Care online doctor. Only a doctor or dentist can prescribe you antibiotics.

Don’t wait to see a dentist

Even if you’ve been prescribed antibiotics, we must reiterate the previous section: antibiotics alone won’t cure your tooth infection.

“Tooth pain won't go away without treatment and the infection may spread to your jaw, cheeks, sinus, and to other areas of your head, brain and neck,” says Dr. Paul Grin. “See your dentist ASAP.”

Antibiotics don’t always help

“If you have an abscess, the antibiotics treat the bacteria outside the tooth,” says Dr. Theodore Davantzis. “You will need root canal therapy to treat the bacteria inside the tooth.”

Dr. Gary Sandler agrees: “The combination of your dentist's treatment, your body's own defense mechanisms, and antibiotics in combination can resolve an infection.”
