Root Canal

What Is Root Canal Treatment?
Root canal treatment is a procedure designed to remove infected tissue from inside a tooth and the surrounding tissues. The treatment is administered within the inner passages of the tooth - between the pulp and the roots. A dentist may need to remove tissue from the surrounding areas. Most root canals result in the removal of the nerve and the pulp. This will usually stop the pain in your tooth but not necessarily in the infected areas around it. There are several reasons why you might need a root canal. The most common is decay caused by poor dental hygiene practices. Other potential causes include cracks or chips and disease. The need for a root canal treatment is usually quite obvious. The main symptom is chronic pain, which is usually worsened by eating, pressure and changes in temperature. Other signs you might need the procedure include a small bump in your gum, tenderness, swelling and darkening of the tooth.

How Does Root Canal Treatment Work?
Root canal treatments usually take place in stages. The pulp and the nerve are removed in one session. A second session is usually devoted to sealing the cavity to prevent further infections.

1. Diagnosis: In order to diagnose the problem, your dentist will need to take an x-ray. This will determine how bad the infection is and whether an extraction will be required.
2. Anaesthetic: The first stage of the actual procedure involves the numbing of the tooth and the surrounding gum. You may need up to three separate injections to ensure you don't feel pain during treatment. The dentist will also place a rubber sheet around your tooth to keep it dry.
3. Drilling: The next stage of the procedure involves the dentist gaining access to the inner structures of your tooth. Unfortunately, this involves drilling a small hole.
4. Removal: The dentist uses a set of specialist tools to remove the nerve and pulp via the drilled hole. Once the infection has been completely removed, the dentist will give you a temporary filling. In many cases, a customised crown is prepared afterwards. The filling usually consists of a rubber compound (which fills the cavity), and a standard filling agent.
5. The final stage: The final stage of a root canal treatment is usually the application of a permanent crown, filling or restorative agent. If there's still some infected material in your tooth, you may need a third appointment. This is because your dentist will leave the tooth open to allow for more drainage.
6. Ongoing care: A lot of people never experience any issues with their treated tooth again.

After Care
What is the post-operative diet for a root canal treatment?

• Avoid crunchy foods such as corn, apples, etc. as they could damage the treated tooth and cause pain.

• Excessively hot and spicy food should also be avoided as it causes more sensitivity.

• Alcohol should be avoided as it causes excessive bleeding.

• Chewy and hard foods could pull out the temporary filling, hence should be avoided.
