Hi. Welcome to Chat Doctor. I read your query. The numbness in lip is not due to antibiotic. Since you mentioned Root canal treatment, you must have got anesthesia injections for it. This or root canal might have pricked nerve which has caused this numbness. This is usually temporary and goes away in 3-4 weeks or may take longer. Take good diet, lots of fluid. Take multivitamin one every day. If the numbness persists for more than that, consult your dentist. Hope the answer helps you. Thank you!
