It is possible for a person to require two or more root canals on the same tooth due to various causes. One of the most common is that the tooth has two roots, making it difficult for the dentist to identify all the canals. Another factor to consider is whether the tooth is still in good condition after the first root canal. If it has been damaged during the procedure or due to a secondary infection, a second root canal may not be possible.
Additionally, if gum disease has progressed enough to endanger the tooth, a root canal may not be an option. If you experience any of the following symptoms, it is likely that you have a failed root canal and need to seek treatment as soon as possible: sensitivity to cold or heat, sharp pain when chewing food, or inflamed gums. Advances in technology are constantly changing the way root canal treatment is performed, so your endodontist can use new techniques that weren't available when your first procedure was performed. If you and your endodontist choose a new treatment, the endodontist will reopen the tooth to access the root canal filling material. Even if you're still trusting your dentist (and they're not going to refer you to a specialist, which might also be appropriate), it's a good idea to get a second opinion on the condition of your tooth and determine if a dental implant or endodontic treatment is the best follow-up. However, if you've had a faulty endodontic and there's no way to remedy the situation, extraction and a dental implant might be the best option. When considering whether or not it is worth getting a second root canal on the same tooth, it is important to weigh all of your options carefully.
Your dentist will be able to provide you with a second opinion and recommended treatment options. Ultimately, it is up to you and your dentist to decide what is best for your oral health.
