What to do: See your dentist or endodontist to save the tooth with root canal treatment. Symptom: Constant and severe pain and pressure, swelling of gum and sensitivity to touch. Possible problem: A tooth may have become abscessed, causing an infection in the surrounding tissue and bone.
Any trauma to a tooth can cause a tooth to need a root canal. Trauma can be grinding your teeth, having a filling done, injury ,biting on something hard, etc. Teeth have live tissue inside of them and this is what dies over time and sometimes suddenly. Kathy Frazar, DDS, FAGD.
