If you’ve been told you may need a root canal treatment, it’s normal to feel unsure — especially if you’re experiencing tooth pain, sensitivity, or swelling. The good news is that root canal treatment is designed to remove infection, relieve discomfort, and help you keep your natural tooth.
Here’s what root canal treatment involves, what to expect during the process, and how recovery typically feels afterwards.
What Is Root Canal Treatment?
A root canal treatment is a procedure done when the nerve of a tooth is inflamed or infected. The goal is to:
- Remove infected or irritated nerve tissue inside the tooth
- Disinfect the canal space
- Seal the tooth to prevent reinfection
- Preserve the natural tooth structure for long-term function
In many cases, a root canal treatment helps you avoid tooth extraction and allows you to keep chewing comfortably with your own tooth.
How Many Visits Does a Root Canal Treatment Take?
Root canal treatment can take one to a few visits, depending on the tooth and the condition being treated.
At each visit, we may numb the tooth and surrounding area to keep you comfortable during the procedure.
Will It Hurt?
During treatment, the area is typically numbed. After treatment, it’s normal for the tooth and gums to feel:
- Slightly tender for the first few hours
- Occasionally tender for a couple of days
This is expected because the tooth has undergone extensive work.
If needed, mild pain relief medication such as Panadol (paracetamol) or ibuprofen can be taken as directed.
What Should I Avoid After My Appointment?
If your tooth was numbed, be careful until numbness wears off.
Avoid:
- Eating or drinking anything too hot
- Chewing on that side while numb
This helps prevent accidentally biting your tongue, lip, or cheek.
Why Does the Tooth Feel Rough or Slightly “Different” Between Visits?
During root canal treatment visits, a temporary filling is often placed on the tooth. This keeps the tooth sealed while allowing easy access at the next visit.
Because it is temporary, it may:
- Feel a little rough
- Feel slightly shorter than a normal filling
This is normal until the tooth is fully restored.
Do I Need a Crown After a Root Canal Treatment?
After the root canal treatment is completed, many teeth need a stronger final restoration to return them to full function.
In most cases, your dentist may recommend a crown (or in certain situations, a veneer) to restore:
- Tooth strength
- Chewing ability
- Long-term protection against fracture
Your clinician will advise what’s best based on how much healthy tooth structure remains and your bite forces.
Do I Need Follow-Up After Root Canal Treatment?
Yes. Follow-up helps confirm that healing is occurring and the surrounding gums and bone remain healthy.
Your dentist may advise a review in a few months, and in some cases we may take follow-up X-rays to check the healing around the tooth.
In Summary
- Root canal treatment removes infection inside the tooth to relieve pain and help you keep your natural tooth.
- Treatment can take one or a few visits, and local anaesthesia is used to keep you comfortable.
- Mild tenderness after the appointment is common; Panadol or Nurofen may help if needed.
- A temporary filling may feel rough or slightly shorter between visits — this is normal.
- A crown is often recommended after a root canal treatment to protect the tooth long-term.
- Follow-up visits (and sometimes X-rays) help confirm proper healing.
