Hi.. antibiotics and mouthwash are for initial relief and they are temporary. Permanent treatment is extraction. Regards

Hi. At your age the wisdom tooth should be extracted if the symptoms of pericoronitis are recurrent, if there is evidence or possibility of damage to the adjacent tooth or if it is likely that the wisdom tooth will not be able to come out fully from its current position. If the said factors, on the other hand, are favourable, you may try antibiotics and mouthwashes on a dentist's advice.
