Inadequate filling of the canal (canals that are poorly cleaned and obturated) Overextensions of root filling materials. Improper coronal seal (leakage)
Root canal therapy is generally safe and effective, with a success rate of more than 95%. Like any other medical or dental procedure, though, a root canal can occasionally fail. This is normally due to a loose crown, tooth fracture, or new decay. Root canals can fail soon after the procedure, or even years later.
At times, however, a root canal treatment fails and tooth infection progresses. How does a root canal treatment fail? Under normal situations, the long-term success rate for root canal treatment ranges between 80-90% and there is a failure percentage of 10-20%.
Your dentist may be responsible for a bad root canal treatment. It ultimately depends on why your root canal failed. If your dentist did not provide an acceptable standard of treatment or live up to their duty-of-care mandate, you might incur unnecessary pain and suffering with root canal complications.
Root canals fail when all of the bacteria is not removed during the actual root canal or reenters the tooth after the root canal has been performed. Common reasons for root canal failure: The removal of all bacteria inside the damaged tooth was not properly removed.
On average, a tooth can last between 10 to 15 years after undergoing a root canal treatment. However, the lifespan can increase significantly if the dentist includes a dental crown along with the treatment.
A dentist can repeat a root canal treatment on a tooth two or more times. While teeth that undergo a root canal procedure can last a lifetime, some of these teeth may not heal properly due to salivary contamination and other reasons.
When you have tooth pain such as a tooth infection, antibiotics can go a long way in helping to address the infection, but unfortunately, antibiotics cannot completely heal an infected tooth. What's more, if you're dealing with an infected root canal, antibiotics really are not going to cut it.
Your options after an unsuccessful root canal treatment include extraction, another root canal procedure, or apicoectomy. Extraction should always be the last resort in dentistry. Replacing a tooth is expensive and requires lots of visits to your dentist.
An infected root canal system may or may not show up on an x-ray. However, an x-ray can help your dentist determine if the infection has spread to the surrounding bones. In some cases, the infection may cause a darkening of the bone or a loss of density, which can be seen on an x-ray.
In most cases, root canal therapy is a better way to treat an infected tooth than an extraction. However, there are exceptions, such as if the tooth has suffered extreme damage. Your dentist will carefully analyze your oral health before making a treatment recommendation.
Tenderness or pain in the tooth when applying pressure, even after recovering from treatment. Swelling after recovery or pimple-like structures developing and leaking pus in the area. Temperature sensitivity, such as a quick, sharp pain after taking a sip of hot coffee or cold soda.
If you've got longevity in mind, know that dental implants can last you for much longer than a root canal and crown. They have a low failure rate and can last decades with good care. With a root canal, you may still end up with your tooth failing or needing to replace crowns after five to 15 years.
While rare, an infection in the bone or an infected root canal are the most common reasons for ongoing post root canal pain. These infections can happen days, weeks, or even years after the procedure.
For example, if the infection is located in the root of the tooth, it can spread to other teeth and to the jawbone. This would lead to an increase of pain. The worst case of an infection spreading could occur if spread to the brain. If this occurs, it could lead to death.
Can you sue a dentist for a bad root canal? Yes, in some cases you can sue your dentist for a bad root canal treatment if the procedure was not performed to an acceptable standard, or if your dentist neglected their duty of care, resulting in unnecessary pain, harm and suffering.
Treatment options after an initial failed root canal treatment include non-surgical re-treatment, endodontic surgery, tooth replantation, transplantation or extraction and replacement with either a single implant or with a fixed prosthesis (18).
Occasionally, an infection can persist or reemerge after you have undergone root canal therapy. When this happens, retreatment of the root canal might become necessary. If that approach is unable to completely and fully eradicate the infection, root canal surgery can resolve the issue.
There are four main reasons why root canal therapy may not heal. They are restorative failures, re-infection, persistent infection and cysts.
A root canal retreatment may be necessary if a previously root canal treated tooth fails to heal or if a recurrent infection is evident. Root canal treatment has a very high rate of success, but as with other medical or dental procedures, infection or inflammation may persist or recur despite our best efforts.
What is the Typical Age for Root Canal Treatment? There is no specific age for root canal treatment. If any individual is experiencing a severe tooth infection, they may require root canal therapy in Yellowknife. However, it is more likely for an individual to require root canal therapy between the ages of 12 to 65.
Not Brushing and Flossing Regularly
One of the biggest issues that can lead to root canals is if you fail to brush and floss your teeth regularly. Remember that brushing and flossing help remove bacteria that can turn into plaque. If that plaque extends too much, it can turn into deep decay, requiring a root canal.
After applying the disinfectant, your dentist will fill your teeth with cement. This cement is called gutta-percha, and it will hold your tooth in its root. After applying the cement, your dentist may use a dental crown to cover the tooth.
Root canals are a way of getting rid of the infection in a tooth without getting rid of the actual tooth. A root canal won't save your tooth—by the time you need one, it's too late for that, but it will allow you to keep it. A dentist or endodontist will drill into the tooth to reach the infected pulp at its core.
