Why Do I Get Cavities So Easily? 

Your teeth are essential to your overall health and appearance, and getting cavities can be a painful and frustrating experience. If you brush and floss every day, you might be a little puzzled that, despite your best efforts, tooth decay can still occur. The truth is this can happen for various reasons, including bacteria buildup, sugar, frequent snacking, or improper oral hygiene. And you’re not alone! Let’s explore why your teeth might get cavities so easily and what you can do to prevent them.

How Do Cavities Happen?

Cavities are permanently damaged areas in your tooth that develop into holes. This tooth decay usually happens through a gradual process that can take months or years and follows the following stages:

Five Reasons You Have Cavities Even if You Brush Regularly

It can be worrisome knowing the effects of tooth decay on your teeth. If you get cavities easily, it’s essential to understand why this might occur. Here are some potential reasons behind your experience:

1. You Are Using the Wrong Toothpaste

No matter how regularly you brush your teeth, using the wrong toothpaste can do more harm than good. Fluoride is one of the critical ingredients in cavity prevention — it helps strengthen tooth enamel and prevent decay. Natural alternatives often lack fluoride, which can impact your oral health. 

Additionally, some kinds of toothpaste may be too harsh on your teeth. Relative dentin abrasion (RDA) measures the erosive potential of the ingredients found in toothpaste. Generally, a rating of 150 and above is considered harmful and can damage your enamel, making it easier for bacteria to cause cavities.

2. Your Molars Are More Prone to Decay

Some teeth are structurally more susceptible to cavities than others. Molars, in particular, have a higher risk of decay. These teeth are positioned at the back of your mouth and are responsible for chewing and grinding food. If you have deep grooves, this can make brushing especially difficult. When food builds up and gets trapped, it can form plaque and eventual cavities.  

If you find these areas challenging to clean, consult your dentist about preventative measures, like sealants or fluoride treatments. They can also recommend best practices for getting into the grooves, including specific brushing techniques or special toothbrushes.

3. Frequent Snacking

Constant snacking, especially on sugary and sticky foods, can significantly increase your risk of developing cavities. As mentioned above, each time you eat, the bacteria in your mouth produce acid using the sugars found in food. Items like candy or toffee can easily get stuck in the crevices between teeth, providing the perfect conditions for harmful bacteria. As a result, the surfaces of your teeth can slowly wear down and lead to decay.

If you can’t help your munching habits, rinsing your mouth with water after each snack is an excellent technique to prevent buildup.

4. Dry Mouth

Saliva is crucial in neutralizing acids and preventing tooth decay because it washes away bacteria and food particles. A dry mouth allows this bacteria to thrive, increasing acidity and the chance of enamel erosion. It can occur for various reasons, like dehydration. However, if this is a chronic experience, it’s essential to speak to your doctor to find the underlying cause and appropriate treatment options.

5. Genetics

Certain genetic variations can affect the composition and strength of your tooth enamel. You might be more susceptible to cavities if you inherited weaker enamel, even if you practice proper oral hygiene. Additionally, genetics can impact your saliva composition, affecting its ability to neutralize acids and prevent decay. 

While you can’t change your DNA, knowing your risk factors can help you take extra precautions to prevent cavities, like regular dental checkups and cleanings. Knowing these underlying characteristics can also help your dentist identify and recommend some at-home techniques to promote better oral health.

Best Practices to Avoid Cavities

Even if you’re more prone to getting cavities, the good news is that with the best practices, you can reduce your risk or catch the decaying process before it leads to severe outcomes. For ideal results, try the following:
