Reviewing Symptoms and History
The dentist reviews your symptoms, dental history, previous treatment, and any changes you have noticed.
Root canal therapy treats inflammation or infection inside a tooth and may help preserve the natural tooth when it can be restored.
During treatment, the affected pulp is removed, the inner canal space is cleaned and sealed, and the tooth is prepared for an appropriate final restoration.
Mackenzie Smiles Dentistry provides root canal assessments for patients in Richmond Hill. A dentist must examine the tooth and review symptoms, dental imaging, remaining tooth structure, and overall oral health before recommending treatment.
Root canal therapy treats the soft tissue inside a tooth, known as dental pulp. The pulp contains nerves, blood vessels, and connective tissue.
Deep decay, cracks, dental trauma, or repeated treatment can irritate or infect this tissue. During root canal treatment, the dentist removes the affected pulp, cleans and shapes the canal system, and fills and seals the space.
Root canal treatment removes the pulp, not the tooth’s roots. The natural tooth remains in place when treatment and restoration are clinically appropriate.
Root canal therapy may be recommended when the pulp inside a restorable tooth has become inflamed, infected, or damaged.
Possible signs include:
Persistent or severe tooth pain
Sensitivity to hot or cold that lingers
Pain when biting or chewing
Swelling near a tooth
A pimple-like bump on the gum
Tooth discolouration following an injury
A deep cavity, crack, or damaged restoration
Symptoms that return after temporary improvement
These symptoms do not confirm that root canal therapy is required. A dental examination and appropriate imaging help identify the cause.
Local anaesthetic helps keep the treatment area numb during root canal therapy. Individual experiences vary, but many patients describe the procedure as similar to other routine restorative treatments.
The inflammation or infection leading to treatment may cause more discomfort than the procedure itself. Some tenderness can remain after the appointment, particularly when the tissues surrounding the tooth were already inflamed.
Tell the dentist if you have dental anxiety, difficulty becoming numb, or concerns about discomfort. The treatment process can be explained before and during the appointment.
The treated tooth and surrounding tissues may feel tender for several days. Follow the instructions provided by the dentist because recovery needs vary by case.
Until the tooth receives its final restoration, avoid chewing hard foods or placing heavy biting pressure on it unless advised otherwise.
Contact the dental clinic if you experience:
Severe or worsening pain
Visible swelling
A reaction to medication
An uneven bite
A temporary filling or crown that comes out
Symptoms that return after initially improving
Do not delay the final restoration. A sealed and appropriately protected tooth has a better chance of remaining functional.
Root canal therapy and tooth extraction address different clinical situations. The appropriate option depends on whether the tooth can be restored and maintained.
| Consideration | Root Canal Therapy | Tooth Extraction |
|---|---|---|
| Main Objective | Treat the inside of the tooth while preserving the natural tooth | Remove the entire tooth |
| Suitability | Requires a tooth with a reasonable restorative outlook | May be recommended when the tooth cannot be predictably restored |
| Treatment Afterwards | Usually requires a final filling, crown, or another restoration | May create a space that could later require replacement |
| Future Planning | Focuses on protecting and monitoring the treated tooth | May involve discussing an implant, bridge, denture, or no replacement |
| Decision Factors | Tooth structure, cracks, infection, gum support, and prognosis | The same factors, plus replacement needs and patient preferences |
Preserving a natural tooth can avoid the need to replace a missing tooth. Root canal therapy is not appropriate when structural damage, poor support, or another condition makes the tooth non-restorable.
Persistent tooth pain, prolonged sensitivity, swelling, or changes following dental trauma should be assessed rather than ignored.
Mackenzie Smiles Dentistry can examine the tooth, review appropriate diagnostic information, explain the findings, and discuss whether root canal therapy, extraction, or another treatment may be appropriate.
Antibiotics do not remove damaged or infected pulp from inside a tooth. A dentist must assess the source of the infection and determine whether root canal therapy, extraction or another treatment is needed. Antibiotics may be considered in specific clinical circumstances, but they do not replace definitive dental treatment.
Yes. A change or loss of pain does not prove that the tooth has healed. Pulp damage can progress even when symptoms change. Arrange an assessment if a tooth had severe pain, swelling, trauma or prolonged sensitivity.
Some root canal-treated teeth need crowns, while others may receive a different restoration. The decision depends on the tooth’s position, remaining structure, cracks and biting forces. Your dentist will recommend the restoration that suits the tooth.
The number of appointments depends on the tooth, infection, anatomy and treatment complexity. Some cases may be completed in one appointment. Others require more than one visit or referral.
Yes. A treated tooth can develop new decay, leakage, fractures or recurrent disease. Some teeth may need retreatment or another procedure later. Regular examinations and a sound final restoration help protect the tooth.
Contact Mackenzie Smiles Dentistry promptly to request guidance and an assessment. Seek urgent medical care if swelling affects breathing or swallowing, spreads rapidly, or is accompanied by other signs of a serious medical emergency.
Persistent tooth pain, swelling, or prolonged sensitivity deserves a dental assessment. The dentist can examine the tooth and explain whether root canal therapy or another treatment may be appropriate.
Contact Mackenzie Smiles Dentistry to request an appointment and discuss the next step for the affected tooth.
