Dentin Exposure: Causes and Prevention

The dentin is in the outer layer of the tooth structure, sitting underneath your enamel. Its function is to protect the nerve-filled pulp, which is also protected by the enamel coating. Since the dentin isn’t as hard as the enamel and contains nerve endings, you may experience sensitivity when it’s exposed. Keep reading to find out its causes and how you can prevent it. 

Causes of Dentin Exposure

One of the ways to prevent dentin exposure is to know how it’s exposed. 

Teeth Grinding

Clenching and grinding your upper and lower teeth together eventually leads to chips and cracks. While this condition is caused by malocclusion and stress, it also occurs during sleep. Prolonged grinding results in a thinning enamel, exposing the dentin as a result. 

We suggest speaking with a professional to help you address this issue. Your dentist may recommend getting a nighttime mouth guard to prevent tooth grinding. 

Gum Recession

Poor dental hygiene can eventually lead to serious dental problems such as gingivitis. This occurs when you don’t regularly brush and floss your teeth. Food debris can get stuck in between your teeth, leading to the accumulation of dental plaque. 

Plaque is a sticky bacteria that produce acid, destroying your tooth enamel in the long run. When not addressed, plaque can lead to gingivitis. As a result, your gums may recede, exposing you to more infection. 

Brushing Too Much

It’s recommended to use a soft-bristled toothbrush with multi-layer bristles for efficient brushing. Using a hard-bristled toothbrush and brushing with too much force can damage the enamel and cause dentin exposure. Soft toothbrushes contain less densely packed bristles, allowing them to bend easily and making them gentler on gums and teeth. 


The discoloration is caused by tannins, a property usually found in coffee or wine, and certain fruits such as peaches and dark berries. This could eventually lead to exposed dentin and make your teeth yellow. Speak with a dentist in Coal Harbour for a dental checkup. We can help you alleviate the problem and prevent more damage. 

How to Prevent Dentin Exposure

When you’re experiencing increased tooth sensitivity, this could indicate a dentin exposure. You need to see a dentist in Vancouver ASAP for a checkup. 

You can prevent dentin exposure by wearing a mouthguard to give you a more comfortable night’s sleep. Reduce your sugar intake and use a soft-bristled toothbrush when brushing your teeth. Make sure to also floss twice a day to ensure your mouth stays clean.

How Plaque and Tartar Differ and How Each Affects Your Teeth

The Differences Between Plaque and Tartar

How Plaque and Tartar Differ and How Each Affects Your Teeth and Gums

Plaque and tartar are related but they are not the same thing. You can still develop either with good oral hygiene, but the better you take care of your teeth and gums, the less chance you will have for periodontal disease and other dental problems.


Plaque on your teeth comes from the bacteria in the food you eat and liquids you drink. When you go for hours without brushing your teeth, like when you’re sleeping, you might feel like something rough and filmy is on your teeth when you wake up. There is something there and that something is plaque. Too much plaque can contribute to cavities, bad breath, and infected gums.

Some things that can contribute to the growth of plaque on your teeth include some medications, breathing through your mouth, and smoking. The longer you go between teeth cleanings, the worse your plaque will get. It can go down under your gums and form tartar. The best way to keep plaque to a minimum is to brush and floss your teeth as directed by your dentist and try to have the best oral hygiene you can.


Tartar is caused by a buildup of plaque on your teeth and often down below the gum level. Tartar is plaque that has been in your mouth long enough to harden. This makes it very difficult to remove and requires the hygienist to use special tools to remove it. These tools are sharp and pointed, but the hygienist is trained to use them carefully to do the job. Plaque and tartar, alone or together, can be a major cause of bleeding gums.

Root Planing and Scaling

Part of good oral hygiene in older patients is to undergo scaling and root planing. They are similar methods of cleaning up plaque and tartar but the depth at which they clean is different. Scaling your teeth is when the hygienist scrapes buildup off of your teeth above your gum line. If plaque and tartar are not too extensive, it might be able to be done in one visit. It is not uncommon, though, to have the procedure done in multiple visits.

Root planing goes down past the gum line to clean the plaque and tartar that has likely been there for decades. Root planing and scaling are major steps in the fight against periodontal disease. If you already have gum disease, these procedures can help to reverse it and get you back on track to have a healthy mouth.

Patients who have diabetes often suffer from dry mouth which can contribute to plaque, tartar, and periodontal disease. If you do have diabetes, it is very important to discuss your oral hygiene habits with your dentist to help maintain your overall health.
