No: Most tooth infections can be cured with oral antibiotics. When they can't, they may need surgery.

In ER yes, but..: It happens often that someone goes to the er for tooth pain and they don't know how to treat the actual problem so they give pain med and antibiotic. I have seen both given in injection form, but it is not the best way. A few daily dosages for more than a week is more common. You need to see a dentist for treatment of the problem besides antibiotics and pain meds.

Only if the: Tooth infection has extended past the local area of the tooth and caused systemic symptoms of swelling, fever, malaise. Oral antibiotics are much more common. If u are in the er and have significant swelling with other system wide symptoms, expect an injection. In the dental office, oral route is the typical first line of attack.

Not usually: Infections from dental sources such as teeth, gums & bone, require that the cause of the infection be eliminated. As an adjunct to this and to prevent further spread and help the body cope with the infection, antibiotics are essential. Oral antibiotics are almost always the typical method. However, im & less frequently IV antibiotics work quicker, are more effective and used in severe cases.
Dr. Babak Jouhari

Not often: Not often, majority of dental infections are treated with taking the medicine orally usually for 7 to 10 days. In cases with systemic problems or in cases that are not responding to oral medication the use of injection is indicated.

A 28-year-old female asked:

How can I get antibiotics for a tooth infection without having a doctor? Er and dentist are too expensive.

Options: There are many options for treatment aside from dentists and the er, including urgent care centers and free clinics. However, you need to have a medical professional take a look, because things other than tooth infections can cause mouth pain, and not all of them respond to antibiotics. I'd suggest calling your local health department for possible free clinics and urgent cares in your area.

Call your dentist: If the antibiotic that your dentist prescribed is not working, it needs to be changed. In addition, the tooth needs to be treated, since antibiotics do not repair damaged teeth.

Need to see x-ray: If the tooth needs root canal treatment that would clear up the problem. If the source is a gum abscess, draining and cleaning the abscess might help. However if you have an infection you should be on an antibiotic.

Antibiotics: In conjunction with definitive dental treatment and good oral hygiene is the cure. Depending on the severity of the infection, an I&D might also be recommended or performed.
