Root canal treatment is a common dental procedure that saves teeth from severe decay or infection, preserving oral health and function. When a tooth’s pulp—the soft tissue inside containing nerves and blood vessels—becomes damaged or infected, prompt treatment is essential to prevent pain, swelling, and potential tooth loss. Dental Touch Clinic, serving Oakville and surrounding areas, explains the root canal process to help patients understand why and when this treatment is necessary, and what to expect throughout the procedure.
What Is Root Canal Treatment?
Root canal treatment, also known as endodontic therapy, involves removing the infected or damaged pulp inside the tooth, cleaning and disinfecting the root canals, and sealing the space to prevent further infection. This procedure allows the natural tooth to be saved rather than extracted, maintaining proper chewing function, alignment, and aesthetics.
The need for a root canal often arises from deep decay, repeated dental procedures, cracks or chips in the tooth, or trauma that exposes the pulp to bacteria. Symptoms that may indicate the need for root canal therapy include persistent toothache, sensitivity to hot or cold, discoloration of the tooth, swelling, or tenderness in nearby gums. Early diagnosis is crucial to prevent complications like abscesses or spread of infection.
The Root Canal Procedure: What to Expect
Root canal treatment is typically performed by a general dentist or an endodontist, a specialist in root canal therapy. The procedure begins with local anesthesia to numb the tooth and surrounding area, ensuring the patient’s comfort. Once numb, a dental dam is placed to isolate the tooth and keep it dry and free of saliva.
Next, the dentist creates an opening in the tooth to access the pulp chamber and root canals. Using specialized instruments, the infected tissue is carefully removed, and the canals are cleaned, shaped, and disinfected. This cleaning step is essential to eliminate bacteria and prevent reinfection. The canals are then filled with a biocompatible material called gutta-percha, sealing the space.
In most cases, a temporary filling is placed to protect the tooth until a permanent restoration, such as a crown, can be placed. Crowns are often recommended after root canal treatment to restore the tooth’s strength and appearance, especially in teeth that have undergone significant decay or damage.
Benefits and Myths About Root Canal Treatment
Root canal therapy offers many benefits, foremost among them the preservation of the natural tooth. Saving a tooth prevents the shifting of surrounding teeth, maintains proper bite alignment, and reduces the risk of jawbone deterioration. The treatment also alleviates pain and infection, improving overall oral health.
Despite its effectiveness, root canals have a reputation for being painful, which is largely outdated. Modern techniques and anesthesia have made the procedure comfortable and routine. Most patients report relief from pain soon after the treatment, and the procedure itself is comparable to receiving a typical filling.
Successful root canal treatment has a high success rate, often exceeding 90%, especially when followed by proper restoration and oral hygiene. It is a valuable alternative to extraction, allowing patients to keep their natural teeth and avoid the complexities of tooth replacement.
Aftercare and Maintaining Tooth Health Post-Treatment
After root canal treatment, it’s important to follow your dentist’s instructions to ensure healing and long-term success. Some mild sensitivity or discomfort may be experienced for a few days, which can usually be managed with over-the-counter pain medication. Eating softer foods and avoiding chewing on the treated tooth until it is fully restored is advised.
Once the permanent crown or filling is placed, maintaining good oral hygiene is essential. Brush twice daily with fluoride toothpaste, floss regularly, and attend routine dental checkups to monitor the treated tooth and overall oral health. Avoiding habits such as chewing hard objects or grinding teeth can protect the restored tooth from damage.
Regular dental visits allow early detection of any issues and professional cleanings to keep your mouth healthy. Root canal-treated teeth can last a lifetime with proper care, preserving your natural smile and oral function.
