What is a root canal procedure?
First let me introduce the root canal as a tooth ‘part’. The outside of the tooth is encased in a hard substance that consists of enamel, dentin, and bone. Inside the tooth are the sensory nerves and the pulp, which occupies a space inside the tooth similar in shape to a canal, hence the name root canal.
A root canal procedure means that the doctor uses specialized instruments to remove the bacterially contaminated root canal tissue. The dentist then seals the root canal with medication to eliminate inflammation and control bacterial growth. Finally, the dentist fills the canal cavity tightly with the appropriate material (usually a dental cement tip) to reduce the risk of the tooth coming back.
When do I need root canal treatment?
Root canal therapy is the preferred method of treating endodontic infections, and patients should visit their nearest dental office as soon as possible if the tooth shows any of the following signs
The first condition
The tooth develops a toothache in response to hot or cold stimuli. Of course, patients in this case need to consult their dentist. This is because some people have problems with their gums to get a toothache under hot or cold stimulation.
The second condition
Periapical infection caused by gum disease, known as periapical tooth infection. In periapical infection, the gums swell and the nerves of the root canals come in contact with the gums (normally, the root canal nerves are not in direct contact with the gums). At this point, a canal of atrophy appears on the gums. The atrophic canal makes the gums repeatedly inflamed, and eventually bacteria will enter the inside of the root canal and infect the pulp, forming pulpitis.
The third condition
The surface of the tooth is damaged, and part of the tooth is lost or damaged. Once the tooth body is unable to protect the tooth, bacteria can enter the root canal and infect the pulp with impunity. In this case, the tooth develops pulpitis. The patient’s tooth becomes painful day and night, with the pain increasing at night.
What does the patient feel during the root canal treatment?
With root canal treatment, the dentist will make different dental plans depending on the number of root canals and the patient’s pain tolerance level. Sometimes the dentist will recommend the first treatment under anesthesia when the pulp is still partially alive. After the dentist has cleaned the pulp, the patient will not feel any pain.
What happens to the tooth after root canal treatment?
After root canal treatment, the tooth will become brittle and prone to fracture when chewing too hard food due to the large amount of tissue loss and loss of continued nutrient function of the pulp tissue. In clinical work, many patients only had root canal treatment without crown protection, and most of them had to extract their teeth in the end.
The tooth is fractured, decayed, infected and other factors that cause bacteria to invade the pulp tissue. Root canal therapy can completely heal the infected pulp. In general, root canal treatment is not significantly painful, but if the tooth is in severe pain patients need to visit the clinic promptly.
