How long will a root canal last?

According to the American Association of Endodontists, root canals have a success rate of over 95% and in most cases they last a lifetime.

There are a few factors that ensure the root canal will last and should be followed.

  • You want to make sure you allow Dr. Kevin Hayes and Dr. Sandy Hayes to perform a permanent restoration of the tooth. That means getting the filling and the crown immediately after the canals have been cleaned of all bacteria and debris.
  • Practice good oral hygiene; that means brushing and flossing at least three times a day especially after meals and before bed.
  • Just because a tooth has had a root canal that does not mean the tooth is safe for as long as it remains in your mouth. That tooth can still get a cavity. Since the nerves are no longer present in that tooth you will not feel any pain or experience any other signs of a cavity. That’s why it is important to get regular cleanings and checkups.
  • If the tooth becomes fractured or you develop an abscess, you will feel pain and know there is a problem with the tooth.

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. If the remaining root(s) become infected in the future, they will also need a root canal performed on them.

There are a few other reasons why your root canal may fail:

  • The first reason is you may not have taken good care of your tooth (teeth). This is commonly seen in children and teens who often have inconsistent oral hygiene habits.
  • If the tooth has more than one root, and one of the roots has a minute infection that is undetectable and goes unnoticed it can cause the root canal to fail. While this scenario is very unlikely, it does occasionally happen.
  • Over time, the seal can become weak and bacteria can enter the tooth. This is also very uncommon but it does happen.

No procedure dental or medical comes with a 100% guarantee to last a lifetime, but if you take care of your treated tooth, the chances of success are great.

"I had multiple bad experiences as a child with the dentist. As a result, I have feared going to the dentist office for years. Dr. Kevin and Sandy are so gentle and caring that I still bring my children to them and we live almost two hours away!" ~ Tasha W.

"Since age 7, I have been extremely fearful of going to the dentist. It was this age that I was told by a previous dentist that I would eventually have to have a root canal and my front tooth capped due to a bicycling accident. This gave me a scary image and sounded painful. When Dr. Sandy told me a root canal was needed, although it was 18 years later, it still sounded scary and painful. Then I was told about sedation. The entire day of the appointment I don’t recall much. When I woke up, the "scary" part was already over and I felt refreshed with zero pain or discomfort. I was completely satisfied with my smile and the results! As for the staff, each person I was in contact with was excellent in accommodating each need that I had and made me feel like I was a part of their family. I would 100% recommend Hayes Family Dentistry and sedation to anyone. The entire experience was, in one word, amazing!" ~ Kellie A.

"I have been extremely afraid to go to the dentist. I had a bad experience about three years ago where my jaw got locked open during a procedure. For about an hour they had to do warm moist compresses and massage my temporal joint to get my jaw unlocked. I was extremely sore for about three and a half weeks. This created a fear of going back to the dentist. My experience with sedation: when I came in that morning I was not anxious about the appointment because I took a pill that morning that helped calm me. I was greeted, they got me comfortable, and I watched a pleasant video about ocean life. I don’t remember anything about that appointment. My next memory was of waking up refreshed and ready to go the next day. I didn’t have any soreness and didn’t have to worry about what I ate because of my joints being sore. It was the most pleasant experience I have ever had at a dental office. I will definitely have sedation again for any kind of future treatment." ~ Sara H.

"Are you afraid to smile because you’re ashamed of your smile? Hayes Family Dentistry can help. Are you saying, “But I’m more afraid of going to a dentist than people seeing my smile?” Hayes Family Dentistry can really help; they helped me. Being afraid of the dentist is nothing to be ashamed of—it’s called dental phobia and you’re not alone. A lot of people suffer from it. But now thanks to sedation dentistry, you don’t have to suffer anymore." ~ Tony "Gator" Harrison
