Toothache isn’t always just a temporary inconvenience. In fact, persistent or sharp tooth pain could be your body’s way of telling you something more serious is going on. But how do you know when it’s time to take action—and what exactly does root canal treatment involve?
At Rumney Endodontics, we’re specialists in diagnosing and treating tooth pain caused by infection or trauma. Our highly skilled team, led by endodontists Dr Andrew Bartley and Dr Cassandra Maunder, is here to help you understand what’s happening inside your tooth—and whether root canal treatment in Cardiff is the right next step.
Here, we explain the common signs you may need a root canal, what the procedure involves, and why specialist care makes all the difference.
What is a root canal and why might you need one?
Root canal treatment is a procedure used to save a tooth that has become infected or inflamed at its centre, known as the dental pulp. This soft tissue contains nerves and blood vessels and runs through canals within the roots of your tooth. When bacteria enter this space—through deep decay, cracks, or trauma—it can cause severe pain and lead to abscesses or tooth loss if left untreated.
Rather than removing the tooth, root canal treatment carefully removes the infected pulp, disinfects the root canals, and seals the space to prevent reinfection. When carried out by a specialist endodontist, the process is safe, comfortable, and highly effective.
Signs you might need root canal treatment
If you’re experiencing any of the following, it’s time to consult your dentist—or better still, book a consultation with our endodontic team:
Lingering pain after hot or cold drinks
Sharp pain when biting or chewing
Spontaneous toothache that wakes you at night
Discolouration or darkening of a single tooth
Gum swelling or a pimple-like bump near the tooth
Tenderness in the jaw or surrounding teeth
These symptoms suggest the pulp inside your tooth may be damaged or infected. The sooner you act, the higher the chance of saving your natural tooth.
What happens during a root canal at Rumney Endodontics?
If you’ve been told you need root canal treatment in Cardiff, don’t panic. The procedure is far more comfortable than its reputation suggests—especially when carried out by a dedicated endodontist.
Here’s what to expect at Rumney Endodontics:
Diagnosis and imaging – We start with a thorough clinical exam and digital X-rays or 3D CBCT imaging to assess the extent of the problem.
Anaesthesia and isolation – Your tooth is numbed completely and isolated with a rubber dam to keep it dry and sterile.
Pulp removal and cleaning – Using microscope-guided instruments, we remove the infected tissue and clean the root canals with precision.
Sealing the tooth – Once the canals are disinfected, we fill them with a biocompatible material to seal out bacteria.
Aftercare and restoration – You’ll return to your general dentist for a final crown or filling to restore full function and appearance.
Most patients experience little to no discomfort during the procedure and return to normal activities within a day.
Why specialist root canal care leads to better outcomes
While general dentists can perform root canals, seeing a specialist endodontist in Cardiff offers several advantages—especially if your case is complex or you’ve had treatment before.
At Rumney Endodontics, we offer:
Advanced imaging and diagnostics to identify hidden anatomy
Microscope-enhanced treatment for greater accuracy
Higher success rates and reduced risk of reinfection
Compassionate care from a team that treats root canals every day
Patients are often referred to us by local dentists for difficult cases, and we’re proud to work closely with general practices across Cardiff to deliver the highest standard of care.
What happens if you delay root canal treatment in Cardiff?
Tooth infections don’t resolve on their own. Without treatment, the infection can spread to surrounding bone and tissue, leading to:
Increased pain and swelling
Tooth loss
Spread of infection to other parts of the body
More complex, expensive treatment
Delaying care could also mean losing the opportunity to save your natural tooth—so if you’re showing signs of infection, don’t wait.
