Impacted wisdom teeth with inflammation,my dentist gives me cefradine capsules and tinidazole tablets to treat my wisdom teeth inflammation ,can i drink two kinds of antibiotics together?

Yes, sometimes used in combination to cover different bacterial groups. Unusual otherwise to use tinidazole instead of metronidazole for dental infections.

As both antibiotics are cephalosporins, and therefore have the same range of efficacy, I wonder about the necessity bro take both. In answer to your question, yes both can be taken together. I would also counsel that you consult with a wisdom tooth expert, a specialist Oraland Maxillofacial Surgeon who has up to 5 years additional formal training and who limits his/her practice.
