Everyone knows that dental cavities are bad, but most people don’t fully understand how they form, why some people are more prone to them, or what factors increase their risk. At Dentistry By Design in Richardson, TX, we believe patient education is just as important as treatment. Understanding the hidden causes and prevention methods of tooth decay can help you protect your smile for life.
Whether you’re brushing twice a day or visiting the dentist regularly, there may still be some things you don’t know about cavities—and they might surprise you.
What Is a Cavity, Really?
A dental cavity (also called caries) is a hole that forms in the tooth when bacteria produce acid that erodes the enamel. It starts with plaque—a sticky film of bacteria that feeds on sugars and starches in your food. As the bacteria digest these sugars, they release acids that slowly dissolve tooth structure. Over time, this leads to decay, which may spread deeper into the tooth if not treated.
According to the CDC, over 90% of adults aged 20–64 have had at least one cavity, and about 1 in 4 adults currently have untreated decay.
Surprising Factors That Can Influence Your Risk of Cavities
Many patients in Richardson and the North Dallas area are surprised to learn that cavities don’t just come from poor brushing habits. Several factors can increase your risk, even if you’re diligent about oral hygiene.
1. Your Saliva Matters
Saliva plays a critical role in neutralizing acids and rinsing away food particles. If you have dry mouth (xerostomia)—whether from medications, aging, or dehydration—you’re at a higher risk for decay.
2. Tooth Position and Shape
Teeth with deep grooves or that are crooked or crowded are harder to clean. Bacteria and food can hide in tight spaces, increasing the chance of cavities forming.
3. Diet and Snacking Habits
It’s not just how much sugar you eat—it’s how often. Frequent snacking or sipping sugary drinks throughout the day keeps acid levels high in your mouth.
4. Genetics and Family History
Some people naturally have weaker enamel, lower saliva flow, or a genetic predisposition to decay. That’s why two people with similar diets and hygiene routines can have very different dental health outcomes.
Cavity Development: It’s Not Always Obvious
One of the biggest myths we hear at our Richardson, TX, dental office is that cavities always hurt. The truth is that early cavities rarely cause symptoms. You may not feel anything until the decay reaches the inner part of the tooth—the dentin or pulp—which can lead to sensitivity, pain, or infection.
That’s why routine dental exams and digital X-rays are so important. We can detect and treat small cavities before they become big problems.
How to Lower Your Risk of Tooth Decay
At Dentistry By Design, we offer a preventive approach that combines technology, education, and customized care. Here are a few expert tips:
- Brush twice daily with fluoride toothpaste
- Floss once a day to remove debris between teeth
- Limit snacking, especially on sugary or starchy foods
- Drink water throughout the day to stay hydrated and support saliva flow
- Visit our office every 6 months for cleanings and checkups
- Ask about dental sealants or fluoride treatments if you’re cavity-prone
