What Causes Dental Cavities?

These are very common questions. What are cavities and how are they caused?

Cavities are a common oral health problem caused by tooth decay damaging both the outer coating of the tooth (enamel) and the inner exposed dentin.

When we fail to brush our teeth the resulting bacteria that naturally occur in our saliva turns the food particles into acid, which in turn creates plaque. Plaque build up sticks to the teeth, dissolving enamel and creating holes in our teeth called cavities.

But how does tooth decay start and why are some of us more susceptible to cavities in the first place?

In this article, our dentists at Country Dental will answer some of the more common questions about cavities and explore some of the reasons behind why we get cavities.

Can Dry Mouth Cause Cavities?

Yes. In general, people with dry mouth tend to be more prone to cavities because they do not have the saliva needed to neutralize the acid in the mouth.

Can Over Brushing Cause Cavities?

There is such a thing as brushing too much and/or too hard. Over bushing your teeth can damage your teeth by cutting away enamel and making your teeth more susceptible to decay and developing cavities.

Can Flossing Cause Cavities?

No. However, not flossing can cause cavities. Failing to floss your teeth at least once a day (or not brushing your teeth at least twice a day) can leave unwanted cavity-causing bacteria in your mouth, allowing plaque to build up and promote tooth decay.

Can Stress Cause Cavities?

Medical science has confirmed that stress can have several affects on the body, one of which can lead to a greater likelihood of getting a tooth cavity. Firstly, stress can trigger a dry mouth and lack of saliva, and as we know, saliva is needed to neutralize the acids in your mouth. Secondly, stress can affect your immune response resulting in inflammation throughout the body. Stress can also make you crave sugary foods, foods that are not good for your oral health and are known to cause cavities.

Can A Change in Diet Cause Cavities?

Yes. Increasing the amount of sugary foods or acidic foods in your diet can increase your likelihood of developing teeth cavities.

What About Gum Recession and Cavities?

The part of your tooth that is protected by your gum is particularly susceptible to decay and/or cavities. As gum recession exposes more of this part of your tooth you will develop a higher risk for cavities.

Can Chemo Cause Cavities?

If you have recently gone through chemotherapy you may have likely experienced the symptom of a dry mouth, which as we know, is a condition that may promote cavities.

Can Braces Cause Cavities?

Orthodontic braces can make it very difficult to properly brush and floss your teeth. Because of this, it is possible for some people to develop small cavities during orthodontic treatment.

Can Illness Cause Tooth Decay & Cavities?

If you resort to sucking on cough candies or throat lozenges while feeling sick you could be at an increased risk for cavities. The prolonged exposure to sugar in the cough candies (particularly if you suck on these when going to bed) can be very harmful for your oral health. Try to find sugar free cough candies or take care to brush your teeth after having a cough candy.
