Root canal failure may occur when there is a lack of blood supply to the tooth’s pulp or if there is an infection in the pulp itself. The blood supply to the pulp is an essential factor in the success of root canal therapy. If there is no blood supply, the tissue will die and may need removal. If there is an infection in the pulp, it may also need to be released. There are several different reasons why a root canal can fail. Below we will cover common Symptoms of a Failed Root Canal.
1. A pimple or boil on the Jaw
When a root canal fails, bacteria can enter the pulp. If the pulp is dead and dying, it will continue to cause a pimple or boil on the Jaw. If the pulp is alive and healthy, it will cause an abscess or boil.
2. Fever and Fever blisters
Root canal infections can cause fever and fever blisters. Fever blisters are a type of inflammation that will form on the skin. They are typically red but can also be purple or black. If you have fever blisters, then you should call your dentist immediately.
3. Depression and Pain in the Jaw
If your Jaw is hurting, it could be due to the root canal failing. The pain will typically be in the lower jaw and around the teeth. It can be felt in the head as well. If you are experiencing this, it would be best to see your dentist immediately. It would help if you also avoid chewing or biting on the affected area until you have seen your dentist.
4. Fluid Buildup in Tooth
A patient who has been suffering from an infected tooth may experience cavitation of the infected area. This may cause a build-up of fluid in their tooth, causing discomfort and possibly pain.
5. Presence of pus-filled Abscesses Near the Treated Tooth
Treated teeth can also develop pus-filled abscesses. These abscesses typically form on the root canal walls and can be painful. If you are experiencing these symptoms, then it is likely that your root canal failed. You must see a dentist as soon as possible to prevent further complications.
6. Swelling near the affected tooth
When a root canal fails, the affected tooth can swell. This swelling can occur on the outside of the tooth or inside of it. The bump will typically form around the tooth and can also be painful. If you are experiencing this, it would be best to see a dentist immediately.
7. Sensitivity when Biting Down on the Affected Tooth
When a tooth is infected, it can be sensitive when biting down on it. This symptom is typically caused by pain from the infection. It can also cause sensitivity in other areas, such as the lips, tongue, or gums. If you are experiencing this, it would be best to see your dentist immediately.
8. Abscess that forms under the crown of a tooth
If you had a root canal and now have an abscess under your crown, your root canal likely failed. Your dentist should be able to tell immediately if this is the case. If they cannot, they will refer you to a specialist specializing in root canal failure cases. They will need to remove your tooth and take x-rays to determine what caused this abscess formation and how to treat it accordingly.These symptoms are signs that you should see a dentist as soon as possible. If you have experienced any symptoms related to root canal failure and still want to proceed with having your tooth extracted, then you should discuss this with your dentist before doing so. You should also ask them about their success rate for extracting teeth with failed root canals and if they have any recommendations for treating these problems.
