Why Your Dentist May Recommend a Root Canal

Your dentist has recommended you have a root canal. But why do you need one, and what can you expect from this dental procedure? Our Thornhill dentists explain.

Why might I need a root canal?

The pulp on the inside of your teeth can become infected with bacteria, often due to a traumatic injury or deep cavity. Only your dentist will be able to examine a given tooth and tell you whether you require this dental surgery, since damage to pulp can occur even if there are no visible chips or cracks in the tooth. 

Root canal therapy is also known as endodontics, and it can save a tooth from being extracted. without a root canal, this severe infection will result in the death of the tooth. Extraction is an event we try to avoid as missing teeth can lead to complex dental issues that can be time consuming, difficult and costly to repair. So if at all possible, we always prefer to preserve the tooth with a root canal. 

Not only can a root canal save your tooth, it can also alleviate symptoms including: 

Severe Toothache Pain

If the tooth pulp is infected, it will often feel painful. You may notice sharp pain whenever you apply pressure to the tooth, such as during chewing. There also might be sensitivity to hot or cold temperatures.

Bump on the Gums

Also known as a dental cyst, this small, pimple-like bump forms on the gums near a tooth that may need a root canal. Dental cysts develop around the roots of an infected or decayed tooth. They may also form if the tooth’s pulp is infected.

Darkening of the Tooth

Infected pulp may cause a tooth to darken in colour due to internal damage. If you notice one of your teeth is a darker shade than the others, there may be an issue with the inner pulp.

What happens during a root canal procedure?

With modern dental technology and techniques, root canal therapy has become a relatively simple and minimally invasive procedure when compared with a tooth extraction or other procedures.

The area will be numbed with anesthesia before your dentist uses a specialized tool to create an opening in the tooth. The bacteria, diseased blood vessels or dead tissue will then be removed from the interior of the tooth. The inner chamber of the tooth will be shaped and irrigated with water, rinsing away any diseased tissue that remains.

Your dentist may also apply an antimicrobial solution to eliminate any remaining bacteria and decrease your risk of further infection.

After the chamber has been thoroughly cleaned and dried, it will be filled with medicated dental material. Your dentist will then place a temporary filling to seal the tooth until a permanent crown is placed.

A few weeks later, the permanent dental crown will be placed to protect the tooth from damage.

If you are curious about others' experience during their root canals, you might type "root canal reviews" into your favourite search engine and read up on the topic. Most teeth that have had root canal treatment can last a lifetime, and help you maintain confidence in your smile.
