A root canal is a treatment used to save a tooth when the soft tissue inside it, called the pulp, becomes inflamed, damaged, or infected. This can happen because of deep decay, a crack, repeated dental work, or an injury to the tooth.
During the procedure, the dentist removes the infected or damaged pulp, carefully cleans the inside of the tooth, and seals the root canals. The tooth is then restored, often with a filling or crown, so it can continue to function normally.
A root canal does not remove the roots of the tooth. It removes the unhealthy tissue inside the tooth while keeping the natural tooth structure in place. With proper restoration and ongoing oral care, a treated tooth can often continue serving you for many years.
Many people still associate root canals with severe pain, but modern treatment is designed to make patients comfortable. Local anesthesia is used, and for many patients, the procedure feels similar to having a large filling completed. The goal is not to create pain; it is to remove the source of pain and infection.
A tooth extraction is the complete removal of a tooth from its socket in the jawbone. Extractions may be simple, such as removing a loose or severely decayed tooth, or surgical, such as removing an impacted wisdom tooth or a tooth that has broken below the gumline.
After an extraction, the body needs time to heal. A blood clot forms in the socket and protects the bone and nerve endings underneath. Following aftercare instructions is important because smoking, using a straw, forceful rinsing, or disturbing the area can interfere with healing and increase the risk of dry socket.
An extraction may provide relief when a tooth is beyond repair, but it also leaves a gap. Depending on which tooth is removed, that space can affect chewing, speech, bite alignment, and the position of nearby teeth. For that reason, a replacement option such as a dental implant, bridge, or partial denture may be recommended after healing.
Whenever a tooth can be predictably saved, preserving it is often the preferred option. Your natural tooth is designed to work with your bite, support the jawbone, and help you chew comfortably. Saving it may also prevent the need for replacement treatment later.
A root canal may be recommended when the infection is inside the tooth but the tooth still has enough healthy structure to be restored. For example, a tooth with deep decay may still be saved if the roots are stable and the surrounding bone is healthy. A cracked tooth may also be treatable if the crack has not extended too far below the gumline or into the root in a way that makes restoration impossible.
Root canal treatment can be especially valuable for back teeth. Molars do much of the work when chewing, and replacing a missing molar can involve more time and expense than saving it. A crown is often placed after root canal treatment on a heavily used tooth to help protect it from fracture.
Choosing a root canal does not mean ignoring a serious problem. It means treating the infection directly while keeping as much of your natural smile as possible. Root canal treatment is commonly used to relieve dental pain and preserve teeth that would otherwise be lost.
Sometimes, even the best dental treatment cannot save a tooth. An extraction may be the healthier option when the tooth is severely fractured, the roots are badly damaged, there is extensive decay below the gumline, or advanced gum disease has caused major loss of supporting bone.
Extraction may also be recommended if a tooth has an infection that cannot be predictably treated with a root canal or if a previous root canal has failed and retreatment is not suitable. In some cases, a tooth may be too weak to support a crown or filling after treatment. Keeping a tooth that cannot be restored can lead to repeated pain, infection, and additional treatment.
Wisdom teeth are another common reason for extraction. They may be removed if they are impacted, causing pain, damaging nearby teeth, or contributing to repeated gum infections.
The important point is that extraction should be based on a careful examination, not simply on the fact that a tooth hurts. Dental X-rays and clinical testing help determine whether the tooth has a reasonable chance of being saved.

Recovery looks different for each treatment. After a root canal, it is normal to have some tenderness for a few days, particularly when biting. Most people can return to their regular routine quickly, although they should avoid chewing hard foods on the treated tooth until the final restoration is complete.
After an extraction, healing takes longer because the body must close and rebuild the socket. Mild swelling, tenderness, and minor bleeding can occur during the first day or two. The dentist may recommend soft foods, gentle brushing, and avoiding activities that could dislodge the blood clot.
A root canal can often be completed in one or more appointments, followed by a permanent restoration. An extraction may appear simpler at first, but if you choose to replace the missing tooth, the overall process can include additional appointments for a bridge, denture, or implant. The American Association of Endodontists notes that extraction can involve more follow-up care when replacement is needed.
It is understandable to compare the immediate cost of a root canal with the cost of an extraction. An extraction may initially cost less, but it is important to consider what happens afterward.
If the extracted tooth needs to be replaced, the total cost can rise. A bridge, implant, or denture involves its own treatment process and maintenance needs. A root canal followed by a restoration may be a more complete investment in keeping your natural tooth, depending on the tooth’s condition and your treatment plan.
Cost should be part of the conversation, but it should not be the only deciding factor. The long-term health of your bite, surrounding teeth, gums, and jawbone also matters.
If you are eligible for the Canadian Dental Care Plan, you can review its covered dental services before your appointment. The plan may help with services such as root canal treatment and tooth extraction, although coverage requirements and patient costs can vary
Not every missing tooth needs the same type of replacement, but leaving a gap without discussing the consequences can create future problems. Nearby teeth may shift toward the empty space, and the opposing tooth may begin to move because it no longer has a tooth to bite against.
Over time, this can change the way your teeth meet and make cleaning more difficult. A missing tooth may also affect chewing efficiency, especially if it is a molar. In the area where the tooth was removed, the jawbone can gradually lose volume because it is no longer receiving stimulation from the tooth root.
A dental implant, dental bridge, or removable partial denture may help restore the space. The best option depends on your oral health, budget, bone levels, and personal goals.
There is no one-size-fits-all answer. Your dentist will assess the tooth, take X-rays, check the gums and bone, and look at how the tooth fits into your bite. They will also consider whether the tooth can be restored strongly enough to function after treatment.
A root canal may be recommended when the tooth has a good long-term outlook. An extraction may be advised when the tooth is too damaged to restore reliably. If the case is complex, a referral to an endodontist may help determine whether the tooth can be saved.
At Courtice Family Dentistry, the goal is to help patients understand their options clearly and choose treatment based on their oral health, comfort, and long-term needs.
A root canal and an extraction are both valuable dental treatments, but they are not interchangeable. A root canal is designed to save a tooth that still has a good chance of long-term function. An extraction is appropriate when a tooth cannot be restored safely or predictably.
If you are dealing with tooth pain, swelling, sensitivity, or a damaged tooth, do not wait for the problem to worsen. Book a dental appointment to find out whether saving the tooth is possible and to discuss the treatment plan that best protects your oral health and smile.
