Hi.. Can understand your concern.. As per your complain swelling and pain in gums is a sign of gum disease causing inflammation of gums and is known as Gingivitis and when it involves deeper tissues it can cause destruction to the underlying bone and pocket formation between the gums and the bone and there is further proliferation of bacteria in the pockets causing deeper infection and the entire sequence is known as PERIODONTITIS.. In case of swelling of gums antibiotics like amoxicillin and metronidazole can provide relief.. For pain anti inflammatory painkillers like Advil or Ibuprofen can be taken.. Topical application of metronidazole containing ointments can help in local clearing of the infection.. Antimicrobial mouth rinses taken concentrated without diluting with water can be helpful.. Saline gargles cab be relieving.. Along with it deep scaling and root planing done by a dentist and the medicines taken orally can have a cumulative effect and can lead to faster healing.. Hope your query is solved.. If you find the answer helpful please write a positive review and click on the found this answer helpful as a token of appreciation.. Thanks and regards..
