Poor-Fitting Dentures
Generally, your gum becomes sore after getting your dentures. However, the soreness and pain may last for a long time due to improper fitting of the dentures.
Contact your dentist to fix your dentures if your gum remains sore for a long time.
Smoking or Tobacco Chewing
Studies show that smoking and chewing tobacco increases your risk of developing gum pain. It also makes you more susceptible to several health conditions, such as oral cancer, weakened immune system, and gum disease.
