Root Canal Treatment

Root Fillings – Root Canal Treatment – Root Canal Therapy & Endodontics

Root canal treatment (RCT) or root fillings as they are often called is a procedure that is carried out to remove infection from within a tooth, disinfect the inside of the tooth and then seal the tooth to prevent further problems.

Root fillings often have a reputation for being painful and whilst the problem with the tooth can be painful, the root canal treatment and root fillings should not be. At Ashbury Dental Care ensuring patients are relaxed and comfortable at all times is a high priority, with some patients actually falling asleep during root canal treatment.

Root fillings, practice makes perfect…

Root fillings can be carried out by any suitably equipped and trained general dental practitioner. At Ashbury Dental Care near Exeter our team of experienced dentists routinely provide root filling and endodontic treatment. We have also invested in specialist root filling equipment, including a state-of-the-art microscope, allowing us to view the tiniest details and achieve excellent results with high success rates. We are pleased to accept referrals from other practices and self referrals from patients themselves.

As a centre of excellence with a multi-disciplinary team of experts we are able to provide a wide range of dental care for our patients, for patients referred into us from their own dentist and for patients who self refer to us. Our root filling expert is here to help you save your teeth!

Why do I need root canal treatment?
Teeth can cause problems and pain for a variety of reasons, such as untreated tooth decay, failing crowns or problems with fillings. A cracked or chipped tooth and repeated dental work on the tooth can also lead to a tooth needing root canal treatment. Damage from trauma (e.g. an accident or fall) may also mean a tooth needs root canal treatment. Teeth needing root canal treatment are often (but not always) painful and if left can lead to abscesses, swelling and uncontrolled infection.
What will happen at the consultation appointment?
If you have been told that you need a root canal treatment then you may need to have a consultation with us before we carry out the root filling. This allows us to thoroughly assess the tooth and discuss with you the risks and benefits of the procedure.


In this appointment we will:

Take time to discuss the problem you have and review your medical and dental histories
Examine the tooth or teeth that require root filling
Take X-rays if needed (if you have had recent x-rays taken, and they are digital we can import these into our system)
Discuss your options in detail and create a treatment plan with a clear description of costs and the appointment(s) you need for root canal treatment

How do you carry out the root canal treatment?
Root Canal treatment is a highly skilled and time-consuming procedure that may require two or more visits to us.


When you attend for your root canal treatment we will first use a topical anaesthetic gel which takes the edge off the injection of local anaesthetic so that you do not have any discomfort during the procedure.

At this stage, we will place a mini surgical drape over your tooth (sometimes called a rubber dam) to isolate it from the rest of your mouth to prevent any bacteria from your saliva contaminating the area after we have thoroughly cleaned the root canals.

Since the root canals can be very small, possibly less than 0.1mm, we use a state-of-the-art  operating microscope to allow us to locate and visualise the canals so that we can see them clearly, allowing us to clean, disinfect and shape them. We reach right to the end of the root with the use of very flexible disposable nickel titanium instruments.

When we are satisfied that the root canal system of your tooth is as clean as possible, we seal it and rebuild the crown portion of the tooth. It is then ready for your dentist to construct a final restoration.


Once we are happy with the root canal treatment we will take a final x-ray and the final restoration can be placed. The area may feel slightly sensitive for a few days after treatment especially you had an infection there previously. For most people this does not cause them any problems and it settles on its own, if required you can take painkillers as you would for a headache.
