Root canal treatment: how does it work?
Root canal treatment, also known as endodontic therapy, is designed to treat the inside of a tooth when the pulp becomes infected or damaged. At Archway Dental Group, the procedure involves carefully removing the infected pulp, cleaning the root canals, and sealing them with a durable material. Our advanced tools and meticulous techniques ensure the procedure is both efficient and thorough, preserving your tooth structure and preventing further complications.
Root canal treatment and reconstruction: the steps
At Archway Dental Group, your root canal treatment involves several precise steps:
- Assessment: We begin with a detailed examination and digital imaging to assess the affected tooth.
- Anaesthesia: Local anaesthesia ensures a pain-free procedure.
- Cleaning: The infected pulp is carefully removed, and the root canals are disinfected.
- Filling: The canals are sealed with a biocompatible material to prevent reinfection.
- Reconstruction: A crown or filling restores the tooth’s strength and functionality.
Our multidisciplinary expertise guarantees a seamless process from diagnosis to restoration.
Price of root canal treatment
The cost of root canal treatment depends on the complexity of the case and the tooth being treated. At Archway Dental Group, we believe in transparent pricing and will provide a clear breakdown of costs during your consultation. We also offer flexible finance options to ensure you can access the care you need without delay.

Root canal treatment: does it hurt?
Modern root canal treatments are largely pain-free, thanks to local anaesthesia and the advanced techniques used at Archway Dental Group. Our team is dedicated to making the procedure as comfortable as possible, addressing any concerns you may have before treatment begins. Most patients report feeling relief from pain caused by the infection immediately after the procedure.
Pain after root canal treatment: what to do?
Some mild discomfort is normal after a root canal treatment as the tooth heals, but this typically subsides within a few days. Over-the-counter pain relief is usually sufficient to manage symptoms. If discomfort persists, contact us – our team is here to provide guidance and ensure your recovery is smooth.








How long does a root canal treatment last?
A well-executed root canal treatment can last many years, especially when followed by proper oral care and regular check-ups. At Archway Dental Group, we use high-quality materials and techniques to ensure durable, long-lasting results. Restorations such as crowns further enhance the lifespan of treated teeth, helping you maintain your natural smile.
Abscess after root canal treatment
An abscess after root canal treatment is rare but can occur if the canals were reinfected or not fully sealed. At Archway Dental Group, we prioritise thorough cleaning and precise sealing to minimise this risk. If you notice persistent swelling or discomfort after treatment, we recommend contacting us immediately for a follow-up assessment.
