### Best Antibiotics for Tooth Infections The type of antibiotic recommended for tooth infections depends on the bacteria causing the infection and any allergies you might have. Common antibiotics include penicillin and amoxicillin. If you're allergic to penicillin, alternatives like clindamycin or erythromycin may be prescribed. Sometimes, metronidazole is used alongside penicillin to cover a broader range of bacteria. ### How to Take Antibiotics Antibiotics are usually taken for about one week, with doses ranging from two to four times a day, depending on the specific medication. Always follow the instructions provided by your dentist and pharmacist. It's crucial to complete the entire course of antibiotics, even if symptoms improve, to ensure all bacteria are eliminated. ### Over-the-Counter Relief While waiting for the antibiotics to take effect, you can use over-the-counter pain relievers like ibuprofen or acetaminophen to manage pain. Rinsing your mouth with warm salt water and using a cold compress can also help reduce pain and swelling. ### When to See a Dentist If you experience symptoms like persistent throbbing pain, swelling, or sensitivity to temperature or pressure, see a dentist as soon as possible. Untreated tooth infections can spread to nearby areas, including the brain, making prompt treatment essential.
