Root Canal Therapy | Save Your Natural Tooth with Expert Care

Common signs include persistent toothache, sharp pain when biting or chewing, prolonged sensitivity to heat or cold that does not go away quickly, a darkened tooth, swollen or tender gums, or a small bump on the gum near a tooth. That said, some teeth that need a root canal show no symptoms at all and are only picked up on X-rays during a routine exam. If something feels off, it is always worth getting it checked rather than waiting.

If an infected tooth goes untreated, the infection will not go away on its own. It can spread to the surrounding bone and tissue, cause an abscess, and eventually lead to tooth loss. In more serious cases, a dental infection can spread beyond the mouth. Getting a root canal when it is recommended is almost always the better outcome compared to extraction, especially since losing a natural tooth has its own long-term consequences for your bite and bone health.

In most cases, yes. Saving your natural tooth is almost always the preferred option. Natural teeth are stronger and more stable than any replacement, and keeping them avoids the chain of decisions that come with an extraction: whether to get an implant, a bridge, or leave the gap, all of which have their own considerations. A root canal preserves the tooth so it can continue functioning normally, usually for many more years with a crown placed on top.

Most root canals are completed in one to two appointments, each lasting roughly 60 to 90 minutes. Front teeth tend to be simpler and faster because they have fewer canals. Molars at the back of the mouth have more canals and may take a little longer or require a second visit. Your dentist will give you a clear idea of what to expect based on which tooth is being treated.

Recovery is generally straightforward. It is normal to feel some tenderness or mild sensitivity in the area for a few days after the procedure, particularly when biting down. Over-the-counter pain relief is usually enough to manage this. You can typically return to normal activities the next day. Until the permanent crown is placed on the tooth, it is a good idea to avoid chewing hard foods on that side. Most patients find recovery far easier than they anticipated.

In most cases, yes. A root canal removes the pulp and nerve from inside the tooth, which can leave it more brittle over time. A crown restores the tooth's full strength and protects it from cracking under everyday chewing pressure. Front teeth, which experience less biting force, sometimes only need a filling, but back teeth almost always benefit from a crown. Your dentist will recommend the right restoration based on which tooth was treated and its condition.

Retreatment is needed when a tooth that has already had a root canal becomes infected again. This can happen if the original seal breaks down over time, a new cavity develops near the treated area, or the tooth sustains new damage. The process is similar to the original procedure: the tooth is reopened, the canals are cleaned again, and it is resealed. Most retreatments are successful, though in some situations your dentist may refer you to an endodontic specialist for more complex cases.

You will want to wait until the numbness fully wears off before eating to avoid accidentally biting your cheek or tongue. For the first day or two, soft foods are a good idea. After that, you can gradually return to your normal diet, though it is best to avoid chewing directly on the treated tooth until the permanent crown is placed. Once the crown is in, the tooth should feel and function just like the rest of your teeth.

The procedure itself is the same. The difference is the urgency. When a tooth infection causes severe pain, swelling, or an abscess, it needs to be addressed quickly rather than scheduled weeks out. At Issa Dental Group, we keep availability for urgent cases so patients in significant discomfort do not have to wait. If you are in pain, call us and we will do our best to see you the same day.
