Top 10 Dental Myths Busted

When it comes to dental care, misinformation is everywhere. From outdated advice to well-meaning but incorrect home remedies, these myths can harm your oral health more than help it. At Arlington Dental, we believe in educating our patients with facts—because healthy smiles are built on smart choices.

Here are 10 of the most common dental myths—and the truth you need to know.

Myth 1: If your teeth don’t hurt, they’re healthy.

Truth: Pain is not the only sign of a problem. Many dental issues, such as cavities, gum disease, and even infections, can progress without causing pain in the early stages. By the time discomfort appears, treatment may be more complex or costly. That’s why regular dental check-ups are essential—even if everything feels fine.

Myth 2: Brushing harder cleans better.

Truth: Brushing too hard can actually damage your enamel and irritate your gums. This can lead to tooth sensitivity and gum recession. Instead, use a soft-bristled toothbrush and gentle, circular motions. It’s not about pressure—it’s about technique and consistency.

Myth 3: Sugar is the only cause of cavities.

Truth: While sugar does play a major role in tooth decay, it’s not the only culprit. Starchy foods (like bread, pasta, and chips) break down into sugars, and acidic foods and drinks can weaken enamel too. Good oral hygiene, not just avoiding sweets, is your best defense.

Myth 4: Flossing isn’t necessary if you brush well.

Truth: Brushing alone only cleans about 60% of your tooth surfaces. Flossing removes plaque and food particles from between teeth and under the gumline, where your brush can’t reach. Skipping floss allows plaque to build up, leading to gum disease and decay in hard-to-see areas.

Myth 5: You don’t need to see a dentist if you’re not in pain.

Truth: Preventive care is the cornerstone of good oral health. Routine exams and cleanings help catch issues early—before they become painful or expensive. Your dentist can also detect signs of oral cancer, bone loss, or systemic health issues that may not have obvious symptoms.

Myth 6: Teeth whitening damages your enamel.

Truth: Professional teeth whitening, when done under the supervision of a dental professional, is safe and effective. It does not damage enamel when used correctly. However, overusing over-the-counter products or using unregulated kits can cause sensitivity or irritation.

Myth 7: Baby teeth aren’t important—they fall out anyway.

Truth: Baby teeth play a crucial role in a child’s development. They help with chewing, speech, and hold space for permanent teeth. Neglecting them can lead to infection, pain, and misalignment issues later on. Children need dental checkups just like adults!

Myth 8: Gum disease only affects your mouth.

Truth: Gum disease is linked to serious health conditions like heart disease, diabetes, respiratory infections, and even complications during pregnancy. Healthy gums contribute to overall systemic health, making gum care more important than you might think.

Myth 9: You should avoid the dentist while pregnant.

Truth: Dental visits during pregnancy are not only safe—they’re recommended. Hormonal changes can make pregnant women more susceptible to gum disease, and poor oral health can affect the baby’s health too. Just be sure to inform your dentist that you’re pregnant so they can tailor your care accordingly.

Myth 10: You’ll lose teeth as you age—it’s inevitable.

Truth: Aging doesn’t have to mean tooth loss. With proper care, you can keep your natural teeth for a lifetime. Brushing, flossing, a healthy diet, and regular dental visits are key to preserving your smile, regardless of your age.
