Root canal risks and complications in Hampstead, North London

Your North London root canal specialists based in Hampstead

Root canal treatment is an extremely common and predictable procedure for our expert endodontists here at Dental Perfection’s North London clinic here in Hampstead. When performed by a highly qualified and experienced specialist, success rates for this procedure are extremely high.

But, as with any medical or dental procedure, you should always consider the potential complications and root canal risks. Our highly trained staff have been carrying out procedures like this for years and are able to greatly reduce many potential risks with careful planning.

Root canal risks – Colour changes

Dental pulp is the living part inside each of your teeth. If this becomes infected, however, it must be removed by root canal therapy. Whilst this saves your tooth from extraction, removes the infected tissue and stops the infection from spreading, it also means this living part is taken away.

Tooth pulp contains connective tissue, blood vessels and nerves, and without it, some patients can experience some form of discolouration in the treated tooth.

This is because, once the pulp is removed, the tooth essentially dies. In some cases, the dead roots of the tooth begin to start showing through the dentin. This only occurs in a very small percentage of cases though.

However, if this does happen, it can easily be aesthetically treated with crowns or veneers to improve their appearance.

Root canal risks – Sinus congestion

Everything within your body is connected to one another and your teeth are no different. A fairly common risk with root canals is that they can cause problems with your sinuses.

This is because, in some circumstances, liquid in your jaw can leak slightly through the membranes in your nose. It may not sound pleasant but because your root canal and sinus cavity are practically neighbours, it could potentially happen.

Whilst this is in no way life threatening, inflammation in the sinus cavities can be irritating with headaches and congestion being the main symptoms.

One way to check if your sinus problems are actually being caused by your root canal procedure will be a continuously salty flavour in your mouth.

In most cases, this problem goes away after a few weeks. If it persists, visit your dentist at Dental Perfection’s North London practice in Hampstead, or speak to your doctor about antibiotics or nasal saline solutions.

Root canal risks – Reinfection

This is the biggest worry many root canal patients have before their treatment. Of course, if you are going through a dental procedure to remove the infection, you want to know it was worthwhile. Whilst reinfection is a root canal risk, your endodontist will go through a number of steps to stop this from happening.

Reinfection can happen if any stage of the root canal treatment is completed incorrectly. Before using fillers, your dentist will clean and disinfect the empty root canals. However, these are made up of many narrow, winding branches. If not carried out by a specialist endodontist, it’s possible some of these passageways could be overlooked or inaccessible.

But, the most common root canal risk is a seal failure. Once your root canal is finished, your endodontist will need to reseal the access hole they used for the procedure. Any cracks or gaps in the seal will allow bacteria to re-enter the tooth.

It is also possible for a seal to erode. Permanent fillings or crowns will be used to close off the outer part of the tooth. Though these are designed to withstand pressure, without the proper care, these can wear down over time and allow bacteria to repopulate.

Root canal risks – Tooth cracking

Root canal treated teeth will never be as strong as they were before the bacterial infection and treatment. As the tooth essentially dies during the procedure, with all the living parts taken out, teeth can potentially become quite brittle.

That’s because one of the main functions of the dental pulp is to keep the tooth nourished and moisturised. This is why crowns are usually recommended post root canal to strengthen the outer area of the tooth again.

Root canal risks – Other complications

In an extremely small percentage of patients, the surrounding nerves around the affected tooth can be disrupted by the root canal procedure. In some cases, this can cause numbness in that area. This is nothing to worry about - it usually goes away within a few weeks.

Another root canal risk is an allergy to anaesthesia. If you have experienced an allergic reaction to anaesthetic during a previous medical procedure, inform your dentist immediately.

Root canal risks – What can you do?

For highly qualified endodontists, like Dental Perfection’s Dr Shahrzad Rahbaran, root canal treatment is an extremely common procedure. That means they’re able to mitigate many of these root canal risks with a skilled team and careful planning.

Before your procedure, you’ll have the chance to speak to your dentist about any potential complications that could occur during or after your treatment. Then, if anything were to happen, you can always come back to the Dental Perfection’s North London clinic in Hampstead to speak to the experts.

And remember – prevention is always better than a cure, so ensure you maintain good oral hygiene following treatment, and that you avoid sugary foods and smoking.

Stay aware of the potential root canal risks and alert a dental or medical professional if you believe there is something wrong.
