If you’re experiencing root canal pain or suspect you might need a root canal, you’re not alone. Many people feel uncertain or even nervous about root canal treatment, largely due to outdated ideas about the procedure.
The truth is that modern dentistry has come a long way. Understanding the root canal procedure might help you feel more confident in your care decisions.
This guide will walk you through everything you need to know about root canal pain, from what causes it to how it’s treated and how you can take steps towards a better and much healthier smile.
What Is Root Canal Pain?
Root canal pain typically occurs when the tooth’s inner part, known as the tooth pulp, becomes inflamed or infected. The pain may range from mild to severe pain that interferes with your daily life.
Why Does The Pain Happen?
Most root canals are usually the result of an infected pulp, deep decay, a cracked or chipped tooth, or trauma to the face. It can also occur after repeated dental work or a previous filling that has worn down over time.
How Do You Know If You Need A Root Canal?
You may need a root canal if you:
- Experience severe pain when chewing or biting
- Feel a lingering sensitivity to hot or cold food
- Notice a small hole or pimple on your gum
- Observe swelling in the gums near the affected tooth
- See your tooth turning a darker colour
- Feel pressure or throbbing around a particular tooth
These signs indicate that the dental pulp may be damaged and need endodontic treatment.
What Happens If Root Canal Infections Are Left Untreated?
Leaving an infected tooth untreated might result in the infection spreading to surrounding tissues or even other teeth. In some cases, it may cause abscess formation, which can cause further pain and complications.
How The Root Canal Procedure Works
Feeling nervous about the unknown is completely normal, but knowing what lies ahead will make all the difference.
Here’s a step-by-step look at how root canal treatment is typically carried out, so you can feel more at ease from the very start.
Step 1: Diagnosis
Your dentist will begin with X-rays to assess the affected tooth, the surrounding soft tissue, and the extent of the infection.
Step 2: Local Anaesthetic
A local anaesthetic is applied to numb the area around the impacted tooth. This ensures the procedure is comfortable.
Step 3: Removing The Infected Pulp
A small opening is made in the tooth to access the pulp chamber. The infected tissue is carefully removed using tiny tools.
Step 4: Cleaning And Shaping
The tooth root and canal space are cleaned and shaped to eliminate bacteria and prepare the area for sealing.
Step 5: Sealing
A temporary filling may be placed at the end. Once thoroughly cleaned, the space is filled with a material to support the structure of the tooth and prevent further infection.
Root Canal Pain After The Procedure
It’s completely normal to experience some tenderness for a few days after your root canal treatment.
This discomfort is often mild and temporary and can be managed with over-the-counter pain relief. Your dentist will provide guidance on how to manage pain as you recover.
Here are simple ways to manage pain at home:
- Stick to soft foods and avoid hard foods that could cause discomfort
- Use cold compresses to reduce any swelling
- Take prescribed medications as directed
- Maintain oral hygiene, brushing gently around the treated area
Can You Prevent Root Canal Pain?
While not all cases are avoidable, there are a few steps you can take to reduce your risk:
- Brush your teeth at least twice daily
- Floss once a day
- Limit sugary foods and drinks
- Visit your dentist for regular dental checkups
- Stop chewing ice or using your teeth as a tool
- Address cavities or tooth pain promptly
When Might Tooth Extraction Be Necessary?
In some cases, if the damage is too extensive or if the tooth is fractured beyond repair, your dentist might suggest removing the tooth. This is usually considered a last resort when root canal treatment is no longer a sufficient option.
What If You Need More Than One Visit?
Some root canal procedures require more than one visit to complete, especially if the infection is severe. Your dentist will explain the steps and what you can expect during your appointments.
How To Tell If Your Tooth Is Healing Well
Signs of a healthy recovery include:
- Reduced pain and swelling
- No sensitivity to hot or cold
- Ability to chew without discomfort
- No visible swelling in the gums
Frequently Asked Questions
Can root canal therapy fail?
While rare, root canal therapy can sometimes fail due to hidden canals, new infections, or incomplete removal of infected pulp.
If this occurs, your dentist will discuss your options, which may include further treatment.
Can you eat after a root canal?
Yes, but you’ll want to stick to soft or cold foods for the first few days. Avoid chewing with the treated tooth until it has been restored with a permanent filling or crown.
Why save a damaged tooth instead of extracting it?
Preserving your natural tooth maintains proper alignment, avoids extra procedures, and supports long-term oral health.
