Four Things You May Not Know About Dental Pulp...

You may be surprised about what you learn!

This month, let’s talk DENTAL PULP. You know – the part of the tooth that we clean out and replace with a special filling during a root canal procedure!

Here are four facts about tooth pulp that we think you should know (if you didn’t already):

Fact #1

A tooth’s pulp is vital, or living… as it’s composed of nerves, blood vessels and tissues that provide the tooth with nutrients. This is why you can rely on your tooth’s pulp to let you know when there’s an issue happening with your tooth! But, here’s the catch: our pulp is no longer needed after the tooth is fully formed during a child’s development. From this point on, the tooth is able to receive its nutrients from surrounding tissues alone. This is why root canal specialists like our Scarborough endodontist are able to save natural teeth with endodontic therapy. If we needed our pulp long after the formation of our tooth, then root canal treatments wouldn’t exist… because they wouldn’t serve a beneficial purpose.

Fact #2

Once a tooth’s pulp is infected, it requires either root canal treatment or extraction in order to prevent serious oral health problems due to the spread of infection – such as periodontal disease, tooth loss and bone/jaw loss. If a patient has the option, it is more beneficial to keep the tooth with an endodontic procedure rather than lose the tooth forever.

Fact #3

The pulp is the innermost layer of the tooth… which means that tooth decay needs to extend past the surface enamel layer, then the dentin layer of the tooth, in order to reach the pulp and require attention from an endodontist.

Fact #4

A tooth’s pulp contains cells that are called “odontoblasts”, which play a role in forming the layer of the tooth that surrounds it (the dentin). The main role of the pulp is to actually form the dentin layer, which is why it’s so important while we’re growing and developing.

We hope you’ve enjoyed learning about dental pulp! It’s sort of our specialty, so we like talking about it. Don’t mind us. :)
