Endodontics —
root canal treatment
Modern root canal treatment is safe, comfortable and highly predictable. Our aim is always to save your natural tooth wherever possible.
Saving teeth through
advanced care
Root canal treatment removes bacteria from the centre and root of an infected tooth. After cleaning, disinfecting and sealing the root canals, the tooth is restored — allowing it to remain in function for the long term. With modern techniques and equipment, it is a well-established, comfortable and predictable procedure.
At Pont Steffan, endodontic treatment is led by Dr Steffan Thomas, who has a special interest in endodontics and holds a Masters degree in the subject from the University of Chester.
Signs you may need treatment
- Persistent or severe toothache, particularly when biting or applying pressure
- Sensitivity to hot or cold that lingers after the source is removed
- Swelling or tenderness in the gum near the affected tooth
- Darkening or discolouration of a tooth
- A persistent spot or abscess on the gum
How does a tooth become infected?
The outer structure of a tooth acts as a barrier against bacteria. If this is compromised — through decay, fracture, erosion, gum disease or trauma — bacteria can enter the interior of the tooth and infect the root and surrounding bone.
