If your dentist has suggested that you need a root canal to fix a tooth with infection or damage, you might be curious about what exactly happens during the procedure or even what a root canal looks like.
Getting ready for a root canal means understanding that you may need to visit the dentist a few times. Even though it might seem like a lengthy process, a root canal is one of the best ways to save a badly damaged tooth and relieve tooth pain caused by nerve issues. The extra visits are definitely worth it for the long-term health of your tooth.

In this article, we’ll break down the 3 stages of root canal treatment so that you know what to expect when it’s time for your appointment.
What is a Root Canal Treatment?
When is a Root Canal Needed?
- Neglected cavities lead to deep decay.
- Several dental procedures on the same tooth.
- Cracks or chips in the tooth structure.
- Tooth injuries, even without visible cracks, can harm the pulp inside.
The root canal is a space inside your tooth that houses the pulp, providing nourishment. The nerves in this pulp react to hot and cold stimuli, often causing pain. The root canal procedure typically involves three main stages, which we’ll discuss further.
3 Stages of Root Canal Treatment
Root Canal Treatment Stage 1: Assessment and initial clean
Once your tooth is numbed, the dentist will make a small opening at the top of the tooth to access and clean the root canal thoroughly. This process involves rinsing the canal with antibacterial solutions and applying medication as needed.
A temporary filling is placed to safeguard the tooth before moving to the second stage of your root canal treatment.
Root Canal Treatment Stage 2: Follow-up Cleaning and Medication
During this stage, your dentist thoroughly cleans the root canal to eliminate any remaining bacteria inside the tooth. X-rays may be taken to verify the length of the root canal for thorough cleaning.
Additionally, medication will be applied to the tooth to address the infection and promote healing.
Root Canal Treatment Stage 3: Sealing the Root Canal
During this stage, your dentist will use specialized rubber points to fill the cleaned root canals before sealing them off. The type of filling—whether temporary or permanent—depends on your tooth’s condition and the treatment plan outlined by your dentist. This step ensures that your tooth is protected and can function normally again.
Complications of Root Canal Treatment
- The tooth’s root may fracture, or the canal may be punctured during the treatment, making it challenging to fill the tooth effectively.
- Occasionally, a dentist may miss identifying all canals in a tooth, which can allow infection to spread to the nearby bone if left untreated.
- Proper sealing of the canal is crucial to prevent reinfection; inadequate sealing may result in the recurrence of infection.
Prevent Tooth Decay and Infections
- Brush your teeth at least twice a day.
- Use toothpaste with fluoride.
- Use a good-quality toothbrush and replace it regularly.
- Schedule regular dental checkups and cleanings at a dental clinic. You can find nearby dentists by searching “dentist near me” online.
