Mouth sores can be painful and bothersome and can sometimes pop up out of nowhere. They are due to different reasons and come in many forms. Some are caused by bacterial, viral, or fungal infections. Other causes are loose orthodontic wires, improperly fit dentures, or sharp edges from a tooth or filling. Several kinds of mouth sores are signs of a certain disease or condition so getting any kind of oral sore that lasts over a week checked out by your dentist is very important. Common mouth sores are:
Canker Sores: They appear as small white or gray ulcers inside the mouth, usually around the inside of the cheek, lip, or gum. There can be only one or several and may often return. They are caused by a number of reasons including fatigue, stress, bacteria, viruses, or allergies.
Cold Sores: Also called fever blisters or Herpes Simplex. They come in groups of fluid filled blisters around the lips and mouth, and sometimes around the nose and chin. You must be careful if you have a cold sore because they are very contagious if caused by the herpes virus type 1. Once you have a cold sore outbreak, the virus stays in your blood and can cause occasional outbreaks.
Leukoplakia: This comes in a thick, white patch around the inside of the cheek, gum, or tongue They are caused by excess cell growth and can be common among smokers. These patches can progress to cancer so it is important to see your dentist immediately if you find this patch in your mouth.
Candidiasis: Also called moniliasis or oral thrush and is a fungal infection. Denture wearers may experience this condition as well as children, elderly, or those with weak immune systems.
