Root Canal: Purpose, Procedure and Risks

A bright smile is a clear sign that your teeth are in good shape! It is great for boosting your confidence and making a positive impression on others! However, it is important to note that certain habits, such as smoking or consuming excessive amounts of sugary foods and drinks, can have a negative impact on your oral health.

When these behaviours are combined with poor oral hygiene, bacteria have a higher likelihood of penetrating the tooth's pulp and causing an infection. In this situation, root canal therapy helps to restore your oral health. 

It is likely that many people are familiar with the word "Root Canal," but not everyone has a comprehensive understanding of its purpose and causes. Therefore, this blog aims to provide a clear understanding of root canal treatment, procedure, and its associated risks.

Let’s get started!

What is Root Canal?

‘Root Canal’ treatment also known as ‘Endodontic Therapy’, is a procedure used to remove infected pulp from the root of a tooth. The aim of the procedure is to remove the infection and safeguard the cleaned tooth from any potential future growth of bacteria.

Why Does One Need a Root Canal?

One may need a root canal when the pulp inside a tooth becomes infected or inflamed. Causes of tooth abscesses include untreated decay, repeated dental operations on the same tooth, or the presence of a crack or chip in the tooth. Untreated, this infection can spread to surrounding tissues and potentially lead to more serious oral health issues.

If any of the following symptoms occur, it may be time to consider root canal treatment:

• Long-term tooth pain
• Sensitive to heat and cold 
• Swollen gums
• Pimples on the gums
• Swollen jaw 
• Tooth discolouration
• Loose teeth

How does a Root canal procedure perform?

Before beginning treatment for a root canal, dentists recommend obtaining an x-ray of the affected tooth. This procedure aids in pinpointing the source of pain and determining whether root canal therapy is necessary. Once the dentist confirms that you need a root canal procedure, they will begin by administering anaesthesia.

1. Anaesthesia 

The dentist starts by putting anaesthesia on the affected tooth and the gums around it. When you get an injection of anaesthetic, you may feel a sharp pinch or a burning feeling, but you can be sure that the pain will go away quickly.

2. Pulp Removal

After giving the patient anaesthesia, the dentist placed a rubber dam over the specific spot. This was done to keep the tooth dry and to separate it from the rest of the mouth. Following that, the dentist operated carefully to make a small hole at the top of the tooth. This allows them to reach the pulp and remove the nerves, blood vessels, and tissue inside the tooth using special tools called "files."

3. Antibiotics

Soon after removing the pulp, the dentist may administer a topical antibiotic to the area to ensure that the infection has been completely eradicated and to prevent the possibility of reinfection. After cleaning and disinfecting the canals, the dentist will fill and seal the tooth using a sealer substance and a rubber-like material called gutta-percha. 

4. The final Restoration

The dentist will complete the procedure by using a soft, temporary material to fill the small opening at the top of the tooth. The purpose of this sealant, known as a crown, is to protect the canals from harm caused by saliva. Once your crown is ready, the temporary filling will be removed, and the permanent crown will be placed.

What are the potential risks involved in a root canal procedure?

• Root canal therapy is an established technique for saving infected teeth, however, it is possible to lose a tooth if the damage is too severe or the enamel is fragile.
• It is possible an ulcer will form at the tooth's root if the bacteria aren’t all eradicated during the procedure.

If you are feeling anxious about undergoing a root canal procedure, it can be beneficial to have a discussion with your dentist. By discussing your concerns and seeking their advice, you can gather the necessary information to make a smart choice that fits into your dental health objectives. So without any delay, book an appointment with an experienced dentist in your city.
