I have no insurance and have a tooth infection. what can i take without a perscription to clear up the infection?

Not much...: Even if you had a prescription for antibiotics, the meds do not fix your rotten tooth... you need to be treated by a dentist for that. Most patients do not have dental insurance, but they still fix their teeth. You'll have to set priorities and possibly finance some of your treatment. You can also seek reduced fee care at a dental school, clinic, or hospital program. All the best...
