If you’re allergic to amoxicillin or it’s ineffective, your dentist might prescribe clindamycin, a common alternative. This antibiotic targets a wide range of bacteria responsible for tooth infections. It’s typically administered orally.
Another option is metronidazole, particularly effective against anaerobic bacteria often involved in severe gum infections or abscesses. Metronidazole comes in pill or gel form, depending on the infection’s location and severity.
For penicillin allergies, azithromycin, a macrolide antibiotic, represents a viable choice. It covers a broad spectrum of bacteria and is usually well-tolerated. However, it’s less potent than some other options against certain bacteria.
The choice of antibiotic depends entirely on the specific bacteria causing the infection, your medical history, and potential drug interactions. Your dentist will perform a thorough assessment before recommending a suitable alternative.
| Clindamycin | Broad-spectrum coverage, oral administration | Potential for gastrointestinal upset |
| Metronidazole | Effective against anaerobic bacteria, oral or topical | May cause metallic taste, avoid alcohol |
| Azithromycin | Alternative for penicillin allergy, broad spectrum | May be less effective than other options against certain bacteria |
Remember: Always follow your dentist’s instructions regarding dosage and duration of treatment. Never stop taking antibiotics prematurely, even if you feel better. Contact your dentist or doctor immediately if you experience any adverse reactions.
