You’ve heard the warnings—but how much of what we believe about cavities is actually true?
Cavities are the most common chronic disease in children and a top concern for adults. But while most people understand that sugar and poor brushing habits contribute to decay, there are still many myths floating around. At All About Smile Dental Group, we believe education is just as important as treatment. Let’s clear up some confusion and debunk 5 of the most common myths about cavities.
Myth #1: Cavities Are Caused by Sugar Alone
The truth: Sugar feeds cavity-causing bacteria—but it’s the bacteria, not the sugar itself, that creates tooth decay. These bacteria produce acid, which erodes enamel over time.
Takeaway: It’s not just how much sugar you eat—it’s how often, and how long it stays on your teeth.
“Yes, cavities can be contagious—but not in the way you might think.”
Myth #2: Cavities Are Contagious (Wait, What?)
The truth: Yes, in a way! The bacteria that cause cavities—particularly Streptococcus mutans—can be transmitted through saliva. This means that sharing utensils, kissing, or even blowing on a baby’s food can spread the bacteria.
Takeaway: It’s important to practice good oral hygiene and limit sharing saliva-related items, especially around young children.
Myth #3: You’ll Know If You Have a Cavity
The truth: Cavities can form without any pain or visible signs. By the time you feel discomfort, the decay may be advanced and require more intensive treatment.
Takeaway: Regular dental checkups help detect early cavities before they become big problems.
Myth #4: Only Kids Get Cavities
The truth: Adults get cavities too—especially as gum recession exposes roots or old fillings break down. Dry mouth from medications or aging can also increase risk.
Takeaway: Good oral habits matter at every age.
Myth #5: Once a Tooth Is Filled, It’s Safe Forever
The truth: Fillings don’t last forever, and decay can still form around or under them if oral care slips.
Takeaway: Keep brushing, flossing, and visiting your dentist even after a filling.

FAQs
How often should I get checked for cavities?
We recommend every 6 months, or more frequently if you’re at high risk.
Can mouthwash prevent cavities?
It can help, but it’s no substitute for brushing and flossing. Look for fluoride-containing rinses.
Is it safe to kiss someone with cavities?
Yes—but if one person has high levels of cavity-causing bacteria, regular hygiene is even more important to reduce transfer.
Are baby teeth cavities serious?
Absolutely. Baby teeth set the stage for lifelong oral health and should be treated promptly.
