What is a root canal?

In the root canal, it follows a treatment sequence where the infected pulp of the tooth is either removed or treated to avoid infections and also to protect the unaffected or contaminated tooth from microbial invasions in the future. In other words, root canal treatment deals with the treatment of the nerve or nerves of the tooth or teeth. Endodontics is a field of specialty in dental science which deals with root canal treatment and also deals with the treatment of the tooth pulp and tissues which are within the tooth. To understand the root canal process in a more clear and better way, let’s understand the tooth structure present in our teeth.

Things to do before going for a root canal treatment

  • Fix or take an appointment with the dentist.
  • Take consultation sessions with the dentists so that you can have everything clear about the subject.
  • Appear for an x-ray examination so that it can be ensured that you do not possess any problem in your dental areas and also you are fit for dental treatment.
  • Then, let the dentist diagnose your condition so that they can easily determine the treatment you need and also proceed with the root canal treatment.

Process of Root Canal Treatment 

Step 1- Anesthetic

  • First, the dentist will apply a small amount of numb medication on the gum near the affected tooth.
  • Once the local anesthetic is injected it takes a few minutes for the medicine to work and the area gets numb.
  • During this procedure, you will be awake, and with the help of a local anesthetic, you will not feel the pain much.

Step 2- Removal of Pulp

  • When the tooth is in a numb state, a general dentist will form or make a small opening at the top of the tooth.
  • After making a small opening at the top of the tooth, the infected or damaged pulp will be visible and exposed.
  • Once the damaged or infected pulp is visible and exposed, the dentists will perform the process of the removal of the pulp with the help of a set of special tools called files.
  • Files are highly useful and helpful in cleaning the canals (pathways) of your tooth or teeth.

Step 3- Antibiotics

  • After the removal of the pulp, the dentist will coat the affected area with a topical antibiotic.
  • The topical antibiotic is coated to make sure that the infection has gone away completely and also to prevent the re-infection of that area.
  • After the completion of the cleaning and disinfection process of the canals is completed, the tooth will be filled and sealed by the dentist with a sealer paste along with a rubber-like material called gutta-percha.
  • After the completion of this stage, dentists may prescribe oral antibiotics. (If needed)

Step-4 Temporary Filling

  • The process will be finally ended by the dentist by the insertion of soft and temporary material at the top of the mouth at the small opening of the tooth.
  • The sealant used here will be highly helpful in the prevention of the damage caused by the saliva to the root canals.

Precautions to be taken after the root canal procedure

  • Take only antibiotics and painkillers prescribed by the dentists to avoid any further infection or problems.
  • Contact your dentist as early as possible if you are suffering pain for a long time or if you are facing any unbearable pain.
  • Follow proper oral hygiene daily without any fail.
  • Do not apply pressure to the area where the treatment took place.

Alternatives to Root Canal Treatment or Therapy 

  • Extraction-  This is one of the most popular alternatives used by people. In this technique, the infected tooth is replaced with either a bridge, implant or partial denture. 
          In the case of teeth, foods play an important role in dental health. Avoiding foods with high sugars and grains is considered effective as it prevents a maximum of the problems related to the teeth like tooth decay and tooth cavities or preventing the infection of the pulp.          It is also believed that eating foods rich in proteins and calcium is also highly helpful for the teeth. Overall, maintaining a healthy lifestyle and brushing the teeth daily will help the teeth and the dental health to be in good condition.   
  • Ozone Gas- This can also be used as one of the temporary alternatives to root canal therapy or treatment. In this technique, ozone gas is used to irrigate the cavity.
Studies have proven that the penetration of the ozone takes place into the tooth tubules, which is beyond the drilled area. Because of the penetration of the ozone, the bacteria gets killed immediately, saving a major part of the tooth, which results in the reduction of the need for the root canal operation.
  •      Direct pulp capping- It is a procedure that is used to treat severely decayed teeth. Materials like calcium hydroxide or MTA are placed directly over the exposed pulp. This material creates a mineral barrier that can both help and protect the exposed pulp and promote tissue repair. After the pulp capping material is applied, the tooth is then filled.
