Root Canal Treatment
In Scarborough
When a tooth’s inner pulp becomes infected or inflamed, root canal therapy can relieve pain and help preserve the natural tooth. At Oasis Dental Centre, Dr. Richard Lai takes a selective, patient-centred approach to endodontic care, focusing on thorough treatment and patient comfort. Root canal therapy removes damaged tissue, reduces infection, and maintains your natural tooth structure so you can continue eating, speaking, and smiling normally.
Root Canal Process
Modern root canal treatment is far more comfortable than its reputation suggests. Before we begin, Dr. Lai reviews each step, tailors the anesthesia to your needs, and proceeds at a pace that keeps you at ease. The procedure involves removing infected tissue, cleaning and sealing the root canals with a biocompatible material, and placing a restoration to protect the tooth. Most appointments take 60 to 90 minutes, and many patients find the experience similar to a routine filling.
If you are experiencing persistent tooth pain, sensitivity to hot or cold, or swelling near a tooth, root canal therapy may be the right solution. Following treatment, a crown is often recommended — particularly for molars — to restore full strength and function. We will walk you through all your options at your visit.
Treatment Areas
Root canal therapy is provided for select teeth, with a focus on predictable outcomes and patient comfort. We commonly treat anterior teeth such as incisors and canines, which typically have single, straight canals that are more straightforward to address. Premolars are also well-suited to endodontic therapy, as they generally contain one or two canals and respond reliably to treatment. For molars, we focus on lower first molars, where careful technique allows us to manage the additional canal complexity effectively. This selective approach ensures we take on cases where we can deliver consistent, high-quality results while keeping your comfort the priority throughout.
Post-Treatment Care
After your root canal, avoid eating until the numbness wears off completely, stick to soft foods for the first 24 hours if you experience any tenderness, and take any recommended pain medication as directed. Avoid chewing on the treated tooth until your permanent restoration is in place. Once healed, care for the tooth like any other — brush twice daily with fluoride toothpaste, floss around it regularly, and attend your routine checkups so we can monitor it over time.
While mild sensitivity after treatment is normal, contact our office if you experience severe pain that doesn’t improve with over-the-counter medication, swelling that increases rather than decreases, or persistent pressure when biting down. With a permanent restoration and proper care, a tooth that has had root canal treatment can last a lifetime. We are here to support you through every stage of healing.
Comfortable, Low-Anxiety Care
We understand that root canals can feel daunting, which is why we take time to walk you through every step before we begin. Anesthesia is tailored to your needs, and we work at a pace that keeps you relaxed and in control throughout the entire procedure.
Precise, Effective Treatment
Dr. Lai carefully removes infected or inflamed tissue, then cleans, shapes, and disinfects the root canals before sealing them with gutta-percha — a biocompatible material that protects the tooth from within. The result is a thorough treatment that eliminates infection and restores the tooth to full function.
Long-Term Tooth Protection
Once your root canal is complete, we discuss the best restoration option to keep your tooth strong and functional for the long term. A crown is often recommended, particularly for molars, to protect against future damage and ensure your bite feels natural and comfortable for years to come.

Frequently Asked Questions
How painful is a root canal?
With modern anesthesia techniques, most patients experience little to no pain during a root canal. We use effective local anesthesia and offer specialized options like single tooth anesthesia for anxious patients. Many patients report the procedure feels similar to having a filling placed. Any discomfort after treatment is typically mild and manageable with over-the-counter pain relievers.
How long does a root canal take?
Most root canal appointments take between 60 and 90 minutes, depending on which tooth is being treated and the complexity of its root canal system. Front teeth with single canals typically take less time than molars with multiple canals. We’ll give you a time estimate during your consultation.
Do I need a crown after a root canal?
Many teeth require a crown after root canal therapy, especially molars that endure heavy chewing forces. A crown provides additional strength and protection to prevent the tooth from fracturing. We’ll discuss whether your tooth needs a crown during your visit and help you plan the restoration timeline.
Can all dentists perform root canals?
While general dentists can perform root canals, not all teeth are appropriate for treatment in a general practice. Dr. Lai selectively treats anterior teeth, premolars, and lower first molars. Complex cases involving second molars or upper first molars are referred to endodontic specialists who have advanced training and specialized equipment for these challenging teeth.
What are the signs I might need a root canal?
Common signs include persistent tooth pain, prolonged sensitivity to hot or cold, tenderness when chewing, swelling near a tooth, or a small bump on the gums near the affected tooth. However, some teeth requiring root canal therapy have no symptoms at all. Regular dental exams help us identify problems before they cause pain.
Is it better to extract the tooth instead of having a root canal?
Preserving your natural tooth is almost always preferable to extraction. A root canal allows you to keep the tooth, maintain proper chewing function, and prevent neighbouring teeth from shifting. Tooth replacement options like implants or bridges are more expensive and invasive than root canal therapy.
How successful are root canals?
Root canal therapy has a success rate of over 95% when performed properly and followed by appropriate restoration. With good oral hygiene and regular dental care, a tooth that has had a root canal can last a lifetime.
Will my tooth be more fragile after a root canal?
The tooth may be slightly more brittle because the pulp and blood supply have been removed, which is why many teeth need crowns for protection. However, with proper restoration and care, the tooth can function normally for many years.
Do you accept dental insurance for root canal treatment?
Yes, we work with most dental insurance plans. Root canal therapy is typically covered at 50–80% by insurance, depending on your specific plan. We’ll verify your coverage and provide a cost estimate before beginning treatment. We also offer payment plans for any out-of-pocket costs.
What happens if I delay getting a root canal?
Delaying treatment can lead to worsening infection, increased pain, abscess formation, and potential tooth loss. The infection can also spread to surrounding teeth or bone. If you suspect you need a root canal, it’s important to schedule an appointment promptly to prevent complications.
