Root canal treatment

Root canal treatment is a conservative therapy during which, in addition to cleansing the decayed areas of the tooth, the inflamed dental pulp – which is responsible for the pain – is also removed. In most cases, the first session will already ease the pain. If more than one session is needed, then, depending on the condition of the tooth, the root canals are either sealed with medication or, if the affected tissues are healed and pain-free, filled.

When is root canal treatment needed?

  • Pulpitis: The most common reason for root canal treatment is pulpitis, the inflammation of dental pulp tissue triggered by the bacteria thriving in the cavities caused by tooth decay. As they proliferate, bacteria and their decomposition products may induce inflammation. This leads to increased pressure within the pulp, which in turn blocks the blood ves-sels running in the pulp, thereby causing stasis – a state in which the normal flow of blood stops – while also causing chemical irritation to the nerve. Root canal treatment helps remove both the infected pulp matter and the infected walls of the root canals.
  • Mechanical impact: On rare occasions, physical damage or forceful im-pacts affecting the tooth may also disrupt blood vessels and nerves, which may eventually cause the tooth to die.
  • Severe periodontitis may also lead to the necrosis of the dental pulp; in such cases, apparently healthy teeth may also need to be root canal treated.

Symptoms that may indicate the need for root canal treatment

The most common symptom indicating a need for root canal treatment is an unmanageable toothache that appears without any apparent reason and may increase – or even decrease – in response to cold or hot stimuli. Initially, this type of pain will normally appear at night, when the patient is at rest. Over time, the tooth may also become sensitive to biting.

Save it or pull it?

Our dentists always work with saving the tooth in mind. We always do every-thing to try and save your natural teeth. However, the chance to save molars with irregularly grown roots may be minimal. Based on a careful consideration of all the available options, our doctors decide, in close consultation with the patient, whether a given natural tooth may be saved and treated.

Root canal treatment – the steps:

  • Overall examination of the mouth including X-ray diagnosis
  • Local anaesthesia to ensure the treatment is pain-free
  • Removal of old fillings and/or tooth matter affected by dental decay
  • Exploring and cleansing root canals
  • Determining root canal length using special tools
  • Disinfecting root canals using laser and a rinsing solution
  • Applying medication to the root canal
  • Temporary filling
  • During the following session: cleansing the root canals once again
  • Root filling
  • Depending on how much tooth matter is missing, the tooth is restored ei-ther by filling or by using an inlay or crown produced by the dental lab. A perfectly fitting restoration guarantees the high quality and long-term suc-cess of root canal treatment.


Reinforcing root canal treated teeth with posts

Symptom-free root-filled teeth may be reinforced using fibreglass posts, pro-vided that the roots are undamaged and the bone matter around the tooth is sufficient. This helps improve the stability and load-bearing capacity of the weakened tooth. Not every root canal treated tooth needs post reinforcement. You can fully trust our team of experienced dental specialists.

The lifespan of root canal treated teeth

Thanks to root canal treatment, many teeth can be saved and kept in the mouth. While their lifespan will be typically shorter than that of natural live teeth, under the right conditions, they will serve for long years to come. None-theless, we recommend that you have your root canal treated teeth checked up every few years by having an X-ray image taken even if you experience no pain whatsoever.

Laser treatment improves the efficiency of root canal treatment

Thanks to a suite of special “hard laser” and “soft laser” technologies, bacteria can be eliminated much more efficiently than by using the traditional meth-ods. When the root canals are not straight, cleansing them with the traditional methods may be difficult or even impossible – especially when it comes to lateral root canals running horizontally, where the traditional methods cannot be used at all. The combined application of the WaterLase iPlus™ laser system and dental diode laser technology makes root canal treatment simpler, more reliable, and more efficient.

Why aren’t root canal treated teeth covered by guarantee?

However experienced and thorough your dentist is, it may still happen that some bacteria survive in lateral root canals. Months or even years later, these may become active once again, inducing an inflammatory reaction around the root of the tooth. Another unpredictable complication is when, as a result of dehydration, the root canal treated tooth becomes brittle and fractures de-spite being handled with the greatest possible care.
