Moxclav 625 (Amoxicillin + Clavulanic acid) is an antibiotic used to treat bacterial infections, including dental or gum infections that cause toothache. However, not all toothaches are due to bacterial infection; some may result from tooth decay, nerve inflammation, or other dental issues. You should not take Moxclav 625 without a dentist’s or doctor’s prescription, as unnecessary antibiotic use can lead to resistance or side effects such as diarrhoea or stomach upset. It’s best to consult a dentist to identify the cause of the toothache and start antibiotics only if a bacterial infection is confirmed.
