Root Canal Fillings – FAQs

Root Canal Fillings

• What is a root canal filling?

  A root canal filling is a dental treatment used to save a tooth that has become infected or damaged internally, ultimately causing the nerve of the tooth to die / be in the process of dying. The procedure involves removing the infected pulp, cleaning the root canals, and sealing them to prevent further infection, allowing the tooth to be preserved.

• Why might I need a root canal filling?

  You may need a root canal filling if the pulp inside your tooth becomes infected due to deep decay, a cracked or broken tooth, repeated dental treatment, or trauma. Symptoms can include toothache, sensitivity, swelling, or pain when biting, although some infections cause little discomfort initially.

• Is root canal treatment safe?

  Yes. Root canal treatment is a routine and safe procedure. It follows strict UK clinical guidelines and infection control standards to ensure patient safety and effective long-term results.

• Does root canal treatment hurt?

  Modern root canal treatment is usually no more uncomfortable than having a standard filling. Local anaesthetic is used to numb the area, and most patients feel little to no pain during the procedure. Any mild tenderness afterwards can normally be managed with over-the-counter pain relief.

• How long does a root canal filling last?

  With good oral hygiene and regular dental check-ups, a root canal–treated tooth can last many years, often a lifetime. In many cases, a crown is recommended afterwards to protect the tooth and restore strength.

• Will I need a crown after root canal treatment?

  Often, yes. Teeth that root treated are usually weaker / more brittle. A crown helps protect the tooth from fracture and restores normal function, particularly for back teeth used for chewing.

• What happens if I do not have root canal treatment?

  Without treatment, the infection can spread, leading to increased pain, swelling, abscess formation and possible tooth loss. In some cases, infection can also affect surrounding bone and tissues. Root canal treatment aims to avoid the need for extraction.

• How long does root canal treatment take?

  Root canal treatment typically takes one or two appointments, depending on the tooth, complexity of the case and the level of infection present. Each visit usually lasts between 60 and 90 minutes.

• Who is suitable for root canal treatment?

  Most patients with an infected or inflamed tooth pulp are suitable candidates. An examination and X-rays will be taken to assess whether the tooth can be successfully treated and restored.

• What is the success rate of root canal fillings?

  Root canal treatment has a high success rate when carried out correctly and followed by appropriate restoration. Maintaining good oral hygiene and attending regular dental check-ups helps ensure long-term success.
