I'm a Dentist, Most People Make This Brushing Mistake Daily

Brushing your teeth is one of those habits most of us barely think about. It's something we've been doing since childhood-morning and night, almost on autopilot. But that familiarity may be part of the problem. Because when something feels routine, it's easy to assume we're doing it right. According to experts, that assumption could be putting our oral health at risk.

Newsweek spoke to dentist Dr. Sam Jethwa, who says many adults are making the same simple-but potentially harmful-mistake every day.

He said: "One of the most common brushing mistakes I see in clinic is patients brushing too aggressively.”

The former president of the British Academy of Cosmetic Dentistry explained that many people believe applying more pressure leads to a better clean or whiter teeth. In reality, the opposite is often true.

Over-brushing can gradually wear away enamel-the protective outer layer of the teeth-leading to increased sensitivity, gum recession and a duller appearance over time.

"Once enamel is lost, it doesn't regenerate, so prevention here is key," he said.

Most People Still Use Manual Toothbrushes

A 2025 YouGov survey found that when it comes to tools, traditional methods still dominate. Most Americans continue to rely on manual toothbrushes, with nearly two-thirds (64 percent) saying they use one regularly.

Electric toothbrushes, including both standard and smart models, are used by around 23 percent of adults, while other options-like disposable electric and ultrasonic brushes-remain far less common, each used by just 4 percent.

Jethwa added that many people opt for medium or hard-bristled brushes, thinking they will provide a deeper clean. However, this choice can contribute to long-term wear on teeth and gums.

Instead, he recommends using a soft-bristled brush and focusing on gentle circular movements rather than harsh, horizontal scrubbing.

"Good brushing is not about force, it's about consistency, technique and timing," he said.

Brushing at the Wrong Time

It's not just how you brush that matters-it's also when.

"The timing issue is just as important," Jethwa said.

After consuming acidic drinks such as fruit juices, coffee, fizzy drinks, or even trending wellness options like apple cider vinegar or carrot juice, enamel becomes temporarily softened.

Jethwa said: "Brushing at this point can essentially scrub away weakened enamel, which increases the risk of long-term damage."

Rather than brushing immediately, patients should wait around 30 minutes after consuming acidic foods or drinks.

"In that time, saliva naturally helps to neutralize acids and reharden the enamel surface," Jethwa said. "Rinsing with water straight after consumption can also help reduce the acid load."

Small Changes, Big Impact

While these mistakes are common, they're also easy to fix. Adjusting your brushing technique, choosing the right toothbrush, and paying attention to timing can all make a meaningful difference.

"These small adjustments in daily habits can significantly reduce enamel wear and help maintain both function and aesthetics over the long term," Jethwa said.

For something most people do without a second thought, brushing your teeth properly might be worth a little more attention.
