I had a check with my dentist last week regarding my gum heaviness in upper right , they took OPD & told me that there is no problem in tooth but your gum has gone up by 1 to 2 mm & they suggested me to take STOLIN GUM ASTRINGENT  & massage gentley on gum twice a day for a month or two . Sometimes pain vanishes ...& sometimes it starts again..
Hello there, Thanks for writing your query, Swelling and heaviness in the gums is the sign of gingival inflammation known as GINGIVITIS. It is caused due poor oral hygiene, improper brushing and flossing that leads to accumulation of bacterial plaque and calculus deep in the gum pockets and root surfaces of the teeth.  Gingivitis presents with symptoms of redness, bleeding gums, swelling, pain, recession and sensitivity. It needs to be treated by thorough professional deep scaling of gums and root planing of the teeth to remove all the irritants, this will help in resolving the symptoms followed by a course of antibiotic and analgesics.  I would suggest you to go for symptomatic treatment at home like gargling with lukewarm saline water or antiseptic mouthwash like chlorhexidine or Betadine.  I hope this helps, take care.
