Possible Reasons Your Filled Tooth Hurts After Months

There are several reasons why a filled tooth may start to hurt after some time. The pain does not happen without a cause, and each situation can be different. Sometimes the problem is small and easy to fix, while other times the tooth may need more treatment. Below are the most common causes that can explain why the pain comes back months after a tooth filling in Phoenix.

Nerve Irritation

The nerve inside your tooth can react when decay gets too close. Even after the dentist removes the decay and fills the tooth, the nerve may stay sensitive. This can cause long-lasting pain or discomfort. Some nerves heal with time, but others do not. If the nerve continues to hurt, it may need further treatment.

Bite Misalignment

If the filling sits too high, it can affect the way your teeth touch. A small change in your bite can cause pressure and pain every time you chew. Over time, this uneven pressure can make the tooth sore and damage the surrounding teeth or jaw.

Recurrent Decay or Infection

Tooth decay can return around or under an old filling. If the area is not sealed well or if bacteria find a way in, a new cavity can form. This hidden decay may not show until the pain starts again. The tooth can also develop an infection if bacteria reach deep inside.

Infection

If bacteria remain in the tooth or enter after the filling, they can cause an infection. This type of pain often feels strong and steady. The area around the tooth may swell or become red. You might feel pressure or notice a bad taste in your mouth. Infections need treatment as soon as possible. They do not get better on their own and can cause serious problems.

Cracks or Fractures

Teeth with large fillings can become weak. Chewing hard foods, grinding teeth, or biting ice can cause small cracks. These cracks may be hard to see but easy to feel. You may feel a sharp pain when biting down or drinking cold water. Cracks let bacteria inside the tooth, which can lead to infection and more damage.
