According to the American Association of Endodontists, root canals have a success rate of over 95% and in most cases they last a lifetime.
Root canal therapy by an Endodontist is the gold standard of care for a painful or infected tooth, and under optimal conditions a patient can expect the treated tooth to last for 20 years or more.
After a root canal, it may only last another 10-15 years. However, there are ways to help your tooth last for the rest of your life. You can have it crowned, which will add extra strength and durability to the tooth.
Candidates For Root Canal Re-Treatment
Root canal re-treatment is performed in an attempt to save the tooth from extraction. Saving the natural tooth often yields healthier results, and many re-treated teeth can function well for years, perhaps even for the rest of the patient's life.
Root canals are put forth as a way to save failing teeth. However: Root canals often fail, which requires the same painful and expensive procedure to be done on the same tooth over and over. Each root canal and post placement further weakens the tooth, meaning eventual extraction is likely.
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.
Cons of Having a Root Canal
Dentists have to drill through the tooth in order to get to the pulp, and additional decay might have to be removed. If the tooth is too weak to function, the dentist will add a crown to it, which will strengthen the tooth and allow the patient to use it like a natural tooth.
A root canal fails when a tooth that has been previously treated with a root canal procedure becomes infected at the root. If this infection is allowed to continue to develop without proper treatment, the infection can potentially spread to other teeth in the area or cause illness in other parts of the body.
Why do root canals fail? As mentioned above, only about five percent of root canals fail, and sometimes it is not actually a “failure.” In cases, of teeth that have more than one root, it is possible that only one root was infected and filled.
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.
Root canals are over 95% successful and can last a lifetime. The most important thing to do to make a root canal last as long as possible is get the permanent restoration (fillings or crowns) on the tooth immediately following the root canal and maintain that restoration with impeccable hygiene.
Can Root Canal Treatment Be Repeated? Although a dentist can do a second or third root canal treatment—or more—on a tooth, the results are unpredictable. Even the most skilled dentists can perform root canal treatment that fails. Studies show that root canal treatment has an 86 – 98% success rate.
A filling is used to treat an area of decay. It stops it from spreading and restores the tooth's strength. Although a filling will last for several years, it won't last forever.
If a root canal tooth hurts years after failure, it is often due to root canal failure or a cracked tooth.
Your front incisor and canine teeth (biting teeth) usually have a single root containing 1 root canal. The premolars and back molar teeth (chewing teeth) have 2 or 3 roots, each containing either 1 or 2 root canals. The more roots a tooth has, the longer the treatment will take to complete.
Most antibiotics like Amoxicillin are not viable to cure a root canal infection. Once the disease has reached its roots, it means the blood vessels with antibacterial defenses have broken down. Hence, antibiotics cannot penetrate inside the tooth into the root where the problem lies.
Retreatment. The most common option for failed root canals is retreatment. This option has the highest success rate, and involves removing the original filling and disinfecting the canal. We then reseal the area to help prevent further infection and to stop bacteria from entering.
The abscess might produce a bulge or recurrent red lump or a pimple on the gums. It may also start to leak bad-smelling liquid. During root canal therapy, draining an abscess comes with some discomfort and bacteria and dead tissues removed to reinstate comfort.
It will get a lot worse
An infection does not just disappear when treatment is not administered. It can travel through the tooth's root to the jawbone and create abscesses. An abscess leads to more pain and inflammation throughout the body. It can eventually lead to heart disease or a stroke.
Root canal treatment in molars was the most common endodontic procedure performed on patients aged 12 to 64 years old with a peak among the 35 to 44- year age group. Root canal treatment on bicuspid teeth, on the other hand, was mainly provided to patients in the 25 to 44-year age group 7.
An alternative to a root canal is a tooth extraction, in which your dentist can replace a damaged tooth with a bridge, partial denture, or implant. This can be an expensive treatment and usually requires several visits to your doctor. If you're a candidate for a root canal, you'll likely experience less pain over time.
If the crack has extended into the pulp, the tooth can be treated with a root canal procedure and a crown to protect the crack from spreading. However, if the crack extends below the gum line, it is no longer treatable, and the tooth cannot be saved and will need to be extracted.
If cared for properly, your teeth can last a lifetime. Your mouth changes as you age. The nerves in your teeth can become smaller, making your teeth less sensitive to cavities or other problems. If you don't get regular dental exams, this in turn can lead to these problems not being diagnosed until it is too late.
Pretty much everyone gets a cavity or two in their lifetime, even with good dental hygiene. The average American adult has three fillings. But if you tend to get a lot of cavities, you may be wondering why. Are you more cavity-prone than other people?
