Why Do My Teeth Hurt?

If you have ever had tooth pain, then you know it is something that you want to have resolved as quickly as possible. Pain in your mouth is not normal, and it is a sign that something is wrong. Don’t ignore pain, you should seek help if you are having continual pain. But you may be asking, “why do my teeth hurt?”

There are many reasons that your teeth can hurt, but we are going to list just a few of the most common.

  • Cavities are probably the most common cause of tooth pain. A cavity is decay in your tooth and it is caused by bacteria. The decay of the cavity could cause your teeth to feel sensitive. The longer a cavity goes unfilled, the worse it usually gets.
  • If you have had a filling in the past, and it has fallen out, then that also could be causing you pain. This is generally because your bite will change and this can lead to pain.
  • TMJ, grinding, and clenching of your teeth are all likely to cause pain. If you wake up with any pain in your teeth, then it probably because you are clenching or grinding your teeth while you sleep. You should discuss this with your dentist to determine solutions for preventing these issues.
  • An abscessed tooth can be incredibly painful. An abscess is an infection around the base of your tooth’s roots. You will have to visit a dentist to have this resolved. This is a perfect example of why you should not ignore pain.
  • When wisdom teeth are beginning to erupt most people will feel some level of discomfort. Talk to your dentist about what the best course of action is when it comes to your wisdom teeth. Many people don’t have room and will need to have them removed to prevent problems down the road.
  • It is common to feel some sensitivity when biting into a cold food. Usually, this isn’t a big deal and is caused by the layer under the enamel, called dentin, being exposed through cracks in the enamel on your teeth. However it could be a sign of something more serious, so if it starts all of a sudden, then we would suggest talking to your dentist.
  • Anyone who has had braces knows that there is normally some pain involved. Over the counter pain medication is usually all you can do to help with this type of pain.
  • An injury is an obvious cause of your teeth hurting. The possibilities from injury include bruising a tooth, discoloration, or even losing a tooth.
