My 2 year and 8 months old son was broken his teeth in an incident about 10 months ago (20-feb-2015) and that time we consulted a dentist he found nothing abnormal but now pus formed on gum. Again we consulted the same dentist he examined and told a gum abscess has been delevoped and prescribed cefixime 50 for 10 days but no results. We took him to another dentist prescribed ofloxacin ornidazole suspension, serriopeptadise tabs and ornidazole ointment for 10 days. Earlier its improving but pus is forming again and again. Somebody suggested us for laser treatment please help me and suggest me what kind of treatment can be given in this case.
