Tooth with a 5 year root canal why pressure now?

Potential causes of pressure after a 5-year root canal:

- Incomplete root canal treatment: The root canal may not have been initially fully successful in removing all the bacteria and infected pulp from the tooth, leading to persistent infection and pressure.

- Fracture: A crack or fracture in the tooth or the root, possibly caused by trauma or excessive chewing forces, can compromise the seal of the root canal filling, leading to discomfort and pressure.

- Reabsorption: The body's own immune system may start breaking down the root structure in response to the root canal treatment. This process, called external root resorption, can cause pressure, pain, and weakening of the tooth.

- Periapical cyst or granuloma: A fluid-filled sac or inflamed tissue can develop at the apex of the root due to chronic inflammation or infection. These lesions can cause pressure and discomfort.

- New infection: Bacteria can re-enter the root canal system through a leaky filling, a crack, or a damaged crown, causing a new infection and pressure.

- Altered bite or occlusion: Changes in the bite or how the teeth come together can put excessive stress on the treated tooth, leading to pressure and discomfort.

- Sinus involvement: If the root of the treated tooth is close to the maxillary sinus, pressure can be felt in the sinus area, especially when there's inflammation or infection in the tooth.

- Referred pain: Pain or pressure from another source, such as a neighboring tooth, jaw joint, or muscle, can sometimes be perceived as coming from the root canal-treated tooth.

It's important to visit your dentist for a comprehensive evaluation to accurately identify the cause of the pressure and determine the best course of treatment.
