Root canal therapy is required if a tooth’s pulp, the soft tissue in the center of its core, becomes infected. The procedure of root canal therapy typically involves removing the pulp from the tooth and filling it with a material that promotes healing. The canal is then sealed off to prevent any future infection, and a crown may be placed on the tooth for support. This procedure can save your tooth from having to be extracted.
Unfortunately, this process doesn’t always work out. Despite how straightforward root canal therapy seems, there are some common reasons why it might fail. You should consult a dentist in Rutherford, NJ if you think your root canal therapy has failed.
Here are some common reasons for the failure of root canal therapy.
Cracked crown leaking filling material
When a root canal is performed, a cracked crown is often the result. The cracks in the crown leak and allow dental material to escape through them. This is a potential problem because the leaking material may build up around your tooth and cause further damage or infection.
New decay to the tooth
If a tooth has new decay or a cracked crown, the infected pulp or filling may end up bulging out of the tooth. This can cause problems similar to those created by cracked crowns, as it allows dental material to escape.
Delay in the placement of restorative devices following the procedure
After root canal therapy, the tooth often needs to be restored with a crown. Keep in mind that you may need additional treatment for this procedure. If the crown isn’t placed on time, it might not heal properly and could cause further issues.
New fracture in the treated tooth
In many cases, a root canal procedure is performed on teeth to control the progression of decay. However, this is not always the case. If a tooth has a new fracture following root canal therapy, it may become damaged and require additional treatment after crown placement.
Saliva entering the restorative structure
During root canal therapy, the canal is sealed off completely. This means no bacteria or saliva can enter the tooth. However, it’s possible that saliva can get into the tooth from other sources, such as when someone bites their lip during chewing.
