Root canal therapy
As you know, the tooth has two parts: the crown and the root. The crown has an outer part called the enamel and an inner part called the dentine, just below the dentine there is a chamber called the pulp chamber. In that chamber, nerve and blood vessels enter the space from the root and nourish different parts of the tooth.
So now we know the nerves and vessels enter the tooth from the root and again enter the pulp chamber or the shield, but no treatment is required until the pulp chamber is exposed to microbial or mechanical factors. When a tooth is exposed to microbial factors, the enamel will begin to break down.
But if caries passes through the enamel barrier and reaches the dentin, Considering that the dentin is a weak organ against caries, it rapidly develops, in which case the teeth become susceptible to cold water and sweets, It should be noted, however, that there is not always dentin involvement associated with pain or sensitivity to colds and sweets, and this caries may not even be seen by the dentist and may require for x-rays to diagnose caries Therefore, patients’ refusal to provide x-ray at this stage is harmful to them And as the caries are asymptomatic, caries will progress, causing caries to enter the pulp chamber, affecting the nerves and vessels.
As long as caries do not enter the pulp room, there is no need for Root canal therapy, which the dentist can diagnose this with the help of radiography or during exfoliation and removal of caries.
As a result of the contact between the pulp chambers through the root to the space around the root of the tooth (bone and gum) contamination from the end of the root enters the area around the tooth, From now on, the end of the root becomes inflamed and the inflammatory cells enter the pulp chamber through the arteries. As a result of the body’s defense against rot in the pulp chamber, the blood volume will increase to protect the body and this volume increases the pressure on the nerve and causes severe pain.
And if it left untreated, it can cause nerve damage, so-called tooth necrosis, or commonly, die.
When the so-called tooth dies and if left untreated, the end of the root begins to infect with an abscess, It should be noted that at the beginning of the nerve involvement and when the tooth is still alive, severe pain is associated with it, and most patients develop severe pain at this stage because of the suspicion of infection and start taking antibiotics.
If there is no infection at this stage then no antibiotics are needed and pain relief is just enough, but if the infection has reached the end of the root, the tooth may become necrotic.
Until the infection becomes active and the abscess develops, there may be no pain despite the infection.
So the tooth that needs Root canal therapy is not always painful.
And because it is not always accompanied by pain, it is not our intention to kill the nerve or to pull the nerve but to cleanse the root of contamination and closing the root end to prevent access to the root end, where the risk of spreading the infection is high.
So it is best to treat the teeth at the beginning stage of caries and not wait for the pain, because nerve contamination can cause many problems and In addition to more tooth decay, more advanced treatments, more time consuming, and more cost to patients.
The newest and most advanced method of Root canal treatment is with a smart digital rotary device.
Endo Rotary Machine works with special files. These files, with their particular shape, form, and Certain matter, take precisely the shape of the root canals and perform root canal treatment with high quality and precision, making the root canal treatment much more precise, better and easier.
The rotary digital device delivers fine, precise, and even better, hand movements to the files instead of the hand and performs root canal treatment and teeth cleaning.
Root canal treatment with Rotary device has much higher quality and faster than the traditional manual method with manual file movements. The rotary technique has the following advantages over the traditional manual method:
High quality and accuracy of root canal treatment
Faster and easier treatment and therefore we have Patient satisfaction
Pain is much less likely to occur after Root canal therapy.
To treat a decaying tooth with pulp chamber involvement and to clean and disinfect the canals we can use both manual and rotary files method. The purpose of both methods is to clean and prepare the tooth canal, remove germs from the nerve canal (infection control), and also create a canal shape that can easily insert the filling material into the root canal. So the better we can get infection control and expand the shape of the channel and access path, the better we can clean and fill the canal.
Rotary files easily remove the dentin walls and also remove the dentin crumbs while rotating. This will cause the dentin fragments to not push toward the end of the root and be directed outward out of the canal by rotating the file.
It also alleviates many clinical problems such as obstruction, Ledge, perforation.
Especially if the nerve canal has curves, these rotary files easily travel the entire length of the path, eliminating germs and clearing the nerve canal.
Another point is that, unlike the rotary technique, in the traditional manual method, one part of the dentine wall may be removed more extensively than the others and Canal shaping got performed uniformly.
With the help of rotary files, all dentin walls are removed evenly and the entire length of the nerve canal is cleared at all equal surfaces and at the end the form we have as the result makes channel filling much easier with gutta-percha material and to increase channel filling speed. Also, the ends of these rotary files are not sharp and pointy and will not damage the tooth, and also will not cause perforation of the root canal walls.
What is the cause of toothache after Root canal therapy?
Root canal therapy is a kind of treatment that most people experience once in their lifetime, and almost everyone before the referral thinks that root canal therapy is very painful and afraid of it.
Root canal therapy is cleansing and suspending the root canals, which causes the root canal to be closed. This will be done with special materials.
By the root treatment, germs and bacteria of the root canals will be destroyed and never get a chance to penetrate again. The pain will come to the patient after root canal treatment. If patients had a lot of pain before the root canal treatment, then they will have pain after the treatment too.
This pain has nothing to do with defects or faults of root canal therapy. Even though the underlying cause of the pain has been cured, the nervous system of the body may become irritated and the pain may reach. Sometimes toothache is an inflammatory reaction.
After root canal swelling is the cause.
