Have you ever wondered why some people seem to get cavities all the time while others rarely do? You brush and floss daily, but somehow, cavities still show up at your dental checkups. Meanwhile, your friend who barely follows a routine has a perfect smile.
Is it genetics? Diet? Oral hygiene? The truth is, cavities are caused by multiple factors, and understanding them can help you take better care of your teeth.
In this guide, we’ll break down what causes cavities, why some people are more prone to them, and how you can protect your smile with advanced dental care.
What Causes Cavities?
Cavities (also called dental caries) occur when bacteria in your mouth produce acids that weaken the tooth enamel. Over time, these acids create holes in the teeth, leading to decay.
Main Causes of Cavities:
- Bacteria & Plaque Buildup – The more bacteria in your mouth, the higher your risk.
- Sugary & Acidic Foods – Sugar feeds harmful bacteria, increasing acid production.
- Poor Oral Hygiene – Skipping brushing and flossing allows plaque to grow.
- Genetics – Some people have naturally weaker enamel.
- Dry Mouth – Less saliva means less natural protection against bacteria.
Even if you take good care of your teeth, you might still be at risk due to genetic or environmental factors. Let’s explore why some people get more cavities than others.
Why Do Some People Get More Cavities?
1. Genetics & Enamel Strength
Just like eye color and height, your teeth are influenced by genetics. Some people inherit weaker enamel, making their teeth more prone to decay.
Fact: Studies suggest that up to 60% of cavities may be linked to genetics (Journal of Dental Research).
Some people naturally have:
✅ Stronger enamel that resists decay
❌ Softer enamel that wears down faster
If your family has a history of frequent cavities, it’s essential to visit a dental clinic in Scottsdale regularly for preventive care.
2. Diet & Cavity Risk
What you eat plays a significant role in cavity formation. Sugary, sticky, and acidic foods create the perfect environment for bacteria to thrive.
| High-Risk Foods | Low-Risk Foods |
| Candy, soda, juice | Water, milk |
| Chips, crackers | Cheese, yogurt |
| Sticky dried fruits | Fresh fruits & veggies |
| Coffee, tea (with sugar) | Nuts & lean proteins |
Fact: Studies show that people who consume more than three sugary drinks per day are 62% more likely to develop cavities (National Institute of Dental and Craniofacial Research).
Tip: Balance your diet with foods that strengthen enamel, such as dairy, leafy greens, and crunchy fruits that naturally clean your teeth.
3. Oral Hygiene Habits
Even if you have strong teeth, poor oral hygiene will lead to cavities. Skipping regular brushing, flossing, and dental checkups allows plaque to build up, weakening the enamel.
Are You Brushing Correctly?
- Brush twice a day for at least two minutes.
- Use fluoride toothpaste to strengthen enamel.
- Floss daily to remove hidden food particles.
- Visit your dentist every six months for a professional cleaning.

4. Saliva Production & Dry Mouth
Saliva is your mouth’s natural defense against cavities. It helps wash away bacteria and neutralizes acids.
But if you have dry mouth, your teeth are more vulnerable to decay. Causes of dry mouth include:
- Certain medications (antidepressants, antihistamines)
- Dehydration
- Smoking
- Health conditions like diabetes
Tip: Stay hydrated, chew sugar-free gum, and use a moisturizing mouth rinse if you experience frequent dry mouth.
5. Cavity-Causing Bacteria
Some people naturally have more cavity-causing bacteria in their mouths. This means that, even with good oral hygiene, they might still get cavities more often.
To lower your risk:
- Use antibacterial mouthwash to reduce bacteria.
- Eat probiotic-rich foods like yogurt to balance mouth bacteria.
- Visit a dental clinic in Scottsdale for advanced dental care and deep cleanings.

FAQs
Can you get cavities even if you brush and floss daily?
Yes! While good oral hygiene helps, factors like diet, genetics, and saliva production also play a role. That’s why regular dental visits are crucial.
How often should I visit the dentist to prevent cavities?
You should visit your dentist every six months for cleanings and checkups. If you’re at high risk for cavities, your dentist may recommend more frequent visits.
Are cavities contagious?
Yes, bacteria that cause cavities can spread through saliva—for example, sharing utensils or kissing. This is why children often inherit cavity-causing bacteria from parents.
Do all cavities require fillings?
Not always. If caught early, cavities can sometimes be reversed with fluoride treatments and better oral care. However, deeper cavities will need fillings.
What’s the best toothpaste to prevent cavities?
Look for fluoride toothpaste approved by the American Dental Association (ADA). It helps strengthen enamel and prevent decay.
Can cavities heal on their own?
No, cavities don’t heal by themselves. However, early decay can sometimes be stopped or reversed with fluoride and improved oral care.
