Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern... As per your complain if you have painful swelling or boil in the area behind the front teeth and if there is decay in tooth leading to pain in tooth along with the swelling then in that case it can be a DENTAL ABSCESS due to pus formation below the root tips of the infected tooth as a result of infection in that area.. The pus perforates the bone and accumulates below the soft tissues leading to pain and swelling.. In this case confirmation can be done by a dentist by taking an x ray and performing root canal treatment or extraction depending on the condition of the tooth followed by antibiotics and painkillers.. In case if there is not tooth infection associated then it can be a gum boil caused by injury by some hard food leading to infection and bacteria entering the gum pocket and causing pus formation.. In this case localized cleaning of the area of the gums followed by antibiotics and painkiller will help.. In case if you have a poor oral hygiene then there can be formation of gingival or periodontal abscess due to deepening of infection in gums. In this case deep scaling followed by antibiotics, painkillers and gum paints can help.. As of now you can take Tramadol 50 mg at night for pain relief.. Hope this information helps.. Thanks and regards.. Dr.Honey Nandwani Arora..
