Why Does My Tooth Hurt?

There are many reasons why your teeth may hurt, but when you’re in pain, you want to know the exact answer for your situation. It’s always a good idea to see your dentist as soon as you notice a problem, but Dr. Nelson Kanning and his team at Kanning Dental in Lawson, MO can tell you the most common reasons why you might be experiencing tooth pain.

Teeth Grinding/TMJ

If you feel a lot of tension in the jaw or you often grind your teeth during the day, you probably also grind your teeth at night. Tooth grinding is called bruxism and can cause problems not just to the teeth, but can cause headaches, jaw pain, and toothaches. Dr. Kanning can provide solutions to save the teeth from wear and tear and solve the side effects of bruxism.

Temperature Sensitivity

Does your morning coffee make your teeth hurt? What about cold food or drinks, or even breathing in cold air? If your teeth are sensitive to temperature, there could be exposed dentin, caused by eroded enamel.


A cavity occurs when enamel is eroded due to tooth decay, which is caused by bacteria in the teeth. You might notice sensitivity to chewing and temperature with the affected tooth. It’s very important to treat cavities early on to avoid costly and painful dental procedures.

Lost or Damaged Filling

Fillings don’t always last as long as they should, and when they’re damaged or missing, the sensitive area of the tooth is exposed, leading to tooth pain. Dr. Kanning can check for further decay and re-seal the tooth to relieve your pain.

Wisdom Teeth

Humans have three sets of molars. The first two are finished erupting from the gums by 12 years of age, but the third set, called the wisdom teeth, don’t erupt until later in adolescence or early adulthood. Some people don’t have them at all, but other people have problems when the wisdom teeth start to come in. There isn’t as much room or flexibility for wisdom teeth to grow, so they can become impacted and painful. If you suspect a problem with your wisdom teeth, it’s important to schedule an exam to ward off a serious systemic infection.


Having braces adjusted or other orthodontic work can cause tooth pain or sensitivity. Many over-the-counter pain relievers can help this pain, but if you think there’s a deeper problem, it’s best to get it checked out.

There are many possible causes for tooth pain, so the best thing to do is to schedule an appointment with Dr. Kanning so that he can perform a comprehensive exam to determine the cause of your pain, and most importantly, recommend the best solution.
