If you’re dealing with ongoing tooth pain, sensitivity, or swelling, a root canal may be the solution that brings the best relief. Despite its reputation, a modern root canal treatment is a safe, effective and comfortable solution that’s designed to remove pain – not cause it.
At Smile Dental, our focus is on saving your natural tooth wherever possible, while making the process clear, gentle and stress-free.
What is a root canal?
Inside every tooth is a soft centre called the pulp. This contains nerves and blood vessels that help the tooth develop. When the pulp becomes infected or inflamed – usually due to deep decay, cracks, or trauma – it can cause significant pain and lead to infection if left untreated.
Root canal therapy removes the infected pulp, cleans the inside of the tooth, and seals it to prevent further infection. The tooth is then restored so it can continue to function normally.
Why might I need a root canal?
You may need root canal treatment if you have:
- Persistent or severe toothache
- Sensitivity to hot or cold that lingers
- Swelling or tenderness in the gums
- A darkened or discoloured tooth
- An abscess or infection at the root of the tooth
Sometimes, there may be very little pain at all – which is why regular dental check-ups are important to catch problems early.
Does a root canal treatment hurt?
This is one of the most common concerns – and the answer often surprises people. With modern techniques and effective local anaesthetic, root canal therapy is usually no more uncomfortable than getting a filling (which, by that measure, isn’t that uncomfortable at all!)
In fact, the treatment is designed to relieve the pain caused by infection. Most patients feel significantly better shortly after treatment, so you’ve got nothing to worry about.
What happens during a root canal treatment?
Root canal therapy is usually completed over one or two visits, depending on the tooth and level of its infection.
First, the tooth is carefully numbed so you stay comfortable throughout the procedure. The dentist then removes the infected tissue from inside the tooth and thoroughly cleans and disinfects the canals.
Once cleaned, the space is sealed to stop bacteria from returning. In most cases, the tooth is then restored with a filling or crown to strengthen it and protect it long-term.
After treatment, it’s normal to experience some mild tenderness for a few days. This usually settles with time and over-the-counter pain relief if needed. Good oral hygiene, avoiding hard foods on the treated tooth until it’s fully restored, and attending follow-up appointments all help ensure a smooth recovery and long-lasting results.
With proper care and a good final restoration, a tooth that’s had root canal treatment can last many years – often just as long as your other natural teeth. Regular check-ups help ensure that everything stays healthy.
Why does root canal treatment focus on saving the natural tooth?
Keeping your natural tooth has many benefits. A treated tooth can continue to bite and chew normally, maintain proper alignment with surrounding teeth and preserve the natural look of your smile.
Extracting a tooth can lead to shifting teeth, bite problems and sometimes, the need for more complex replacement options. Root canal therapy helps avoid these issues by preserving what you already have.
If you’re experiencing tooth pain or think you may need a root canal, don’t wait. Early treatment can prevent further infection and help save your tooth.
