Root Canal Treatment (Endodontics)
Root Canal Treatment (Endodontics) is needed when the nerve inside the tooth becomes infected through decay or trauma.
You may not feel any pain in the early stages of the infection. In some cases, your tooth could darken in colour. This can mean that the tooth has died or is dying.
If the root canal is left untreated, a painful abscess may develop, and the infection could spread. A tooth with dead pulp will usually have to be removed.
The Treatment
Our Root Canal Treatment clears up the infection by thoroughly cleaning out the root canal and sealing it. We can usually save the tooth this way.
It is a skilled and time consuming procedure which can take two or more visits. We will provide you with an estimate and treatment plan at the start of your treatment.
The Results
The treatment has a high success rate and usually lasts many years. However, if the infection does return we can repeat the treatment.
In the past a tooth would often darken after Root Canal Treatment, but Smile Studio Penarth uses modern techniques to reduce the risk of this. If there is any discolouration we can offer a number of treatments to restore the natural appearance of your teeth.

Thanks so much Michael Scott11/10/2025Trustindex verifies that the original source of the review is Google. I had a minor dental emergency, and my usual dental practice in Penarth said I'd have to wait 5 days to see a dentist. So I called Smile Studio, and they saw me within 45 minutes. The dentist did a great job, and the fee was very reasonable. I've now registered with them. Alana O'Brien09/10/2025Trustindex verifies that the original source of the review is Google.

As i walked in i was greeted by the most lovely, polite receptionist. Then i went upstairs and met the dentist Chris who put my mind at ease instantly. His, and his nurses manner are both wonderful. Really made me feel relaxed and comfortable. The tooth extraction was quick and painless, i didnt even realise it was done. This is truly a superb dental practice, plus the prices are very competitive. I am so glad to have found Smile Studio. Glenda Dudley24/09/2025Trustindex verifies that the original source of the review is Google. Appointment with Dr. Rory Dewhurst at Smile Studio, Penarth. Excellent as always. Rory is kind, gentle, clear about the process and the steps to be taken. He has a calm, reassuring demeanour. During treatment, where he uses the latest techniques in dentistry, he regularly checks that all is well and explains how far through the treatment we are, so you are clear about what to expect next. The final result never disappoints. His work is of the highest standard. I trust Rory to provide the best level of care and treatment at every appointment. I highly recommend Rory, he is a consummate professional. Nick Clarke19/09/2025Trustindex verifies that the original source of the review is Google.
