The Leading Causes Of Cavities

Cavities are one of the most common dental problems—and one of the most preventable. But knowing what actually causes cavities can help you make small changes that protect your smile. At Ryan Dental, we believe prevention starts with understanding, not just instructions.

Here’s a closer look at the main culprits behind cavities and how you can stay one step ahead.

Sugar and Acid: A Tough Combo For Teeth

It’s no secret that sugar is a major cause of cavities. When you eat or drink something sugary, the bacteria in your mouth feed on it and produce acid. That acid attacks your enamel, slowly wearing it down over time. Frequent snacking on sweets or sipping sugary drinks throughout the day gives bacteria a constant supply of fuel—and your teeth less chance to recover.

Acidic foods and drinks, like soda, sports drinks, and citrus fruits, can also weaken enamel even without added sugar. The more often your teeth are exposed to acid, the greater the risk.

Poor Oral Hygiene Habits

Brushing and flossing aren’t just about keeping your breath fresh—they’re your best defense against cavities. Skipping daily brushing or rushing through flossing leaves plaque behind. That plaque hardens into tartar, trapping bacteria against your enamel and making it easier for cavities to form.

Flossing is especially important because it cleans the spaces between your teeth where your toothbrush can’t reach. Cavities often start between teeth when plaque builds up unnoticed. Taking a few extra minutes each day to floss can save you a lot of trouble (and dental work) down the road.

Even if you brush twice a day, missing certain areas—like the back molars or along the gumline—can allow decay to start in hard-to-reach spots.

Dry Mouth and Reduced Saliva

Saliva does more than keep your mouth comfortable. It helps wash away food particles, neutralize acids, and repair early enamel damage. If you suffer from dry mouth due to medications, health conditions, or dehydration, your risk of cavities goes up.

Staying hydrated, chewing sugar-free gum, and talking to your dentist about options can help keep your saliva flowing and your teeth protected.
