Very often when a wisdom tooth is erupting into the mouth a small flap of gum tissue forms behind the tooth that traps food and bacteria and thus sets up a condition for a dental infection. Rinse with salt water or a mixture of hydrogen peroxide diluted half and half with water. Gently clean the area with a tooth brush and contact your dentist. There may also be dental decay or a cyst in the area which will need immediate attention.
