What is Root Canal Therapy?
Root Canal therapy refers to a treatment in which dentist removes the bacterial infection, which has entered the pulp or nerve chamber. There are several reasons why a tooth needs root canal therapy such as deep decay, big feeling, trauma or repeated dental work
How root canal therapy is done?
Root canal treatment is routinely performed in one or two visits. First local anaesthetic is administered to numb the tooth, then your dentist will use a protective rubber dam to keep the tooth clean and saliva free during procedure.
Next shaping files are used to shape and clean infected or inflamed nerve after an opening is made through the tooth.
During the procedure the cleaning solutions are used to help clean up any remaining bacteria or debris. Also X-rays are periodically taken to inform the dentist about ongoing process.
Using LASER in Root Canal Therapy
Here is when laser beams come to help the dentist to make sure these canals are free of debris and bugs. This technology is called Photon Induced Photoacoustic Streaming or PIPS. Laser energy is activated into the tip, creating a series of shock waves travelling down to entire canal system to its apical part. As this photon activity continues, a flushing tiny particles like a cloud can be seen exiting the canal.
This action has been demonstrative over and over in experimental test models and clinical trials. Resulting surfaces, shown by studies, have demonstrated extremely clean and intact surfaces of main canals and lateral canals, which normally are not accessible.
The remaining canal preparation shows effective removal of debris from entire root canal system. Photo Induced Photo Acoustic Streaming can be used with less need for over instrumentation and is minimally invasive.
Obturation is generally done by placing a rubber-like material with a sealer that fills the entire length of the canal. A temporary feeling is then place.
Root Canal therapy treats the disease of the pulp of the roots but the treatment is not completed until the tooth is restored to the functional stage. this means a crown or other type of restoration is necessary to make it operational again. Normally two days of discomfort is not unlikely following a root canal therapy. This can be managed with pain killers.
Having said that laser root canal therapy has dramatically reduced the period of post operative pain and discomfort due to being minimally invasive and also the anti bacterial property of the laser plays a very important role in reducing this period.
A few tips to remember following root canal therapy:
First you should never chew hard food are before final restoration is place or tooth may crack.
Second the longer you wait to replace the final restoration the more likely bacteria reinfect the canal system, requiring to repeat root canal therapy all over again.
Root canal therapy is like any other treatments is not free of complication, for example: A shaping file may break inside the canal or it is possible to miss an extra canal also sometimes the perfect seal may not be possible due to shape of the canal.
In the event of root canal treatment failure other options can be consider including removing the tooth, repeating root canal therapy or referring to an endodontist.
Keep in mind that the longevity of root canal therapy depends on proper brushing, flossing, diets and last but not the least regular checkup.
