I'm a Dentist, Here's One Thing That Can Prevent Gum Disease

A dentist has revealed a surprisingly simple step that could make all the difference when it comes to preventing gum disease.

Forty-seven percent of U.S. adults aged 30 and older have some form of gum disease, according to Gumdisease.com. Despite how common it is, confusion remains widespread.

For Dr. Soumaya Zinet, the most effective form of prevention is also the most straightforward.

She told Newsweek: "If I had to choose the single most important thing people can do to prevent gum disease, it would be effective daily plaque removal.”

What Happens Inside Your Mouth-and Why It Matters

It's completely normal for bacteria to live in a healthy mouth. The Centers for Disease Control and Prevention (CDC) explains these bacteria constantly form a sticky, removable film on teeth known as plaque.

When plaque isn't removed, it begins to build up, irritating the gums and causing inflammation-an early stage of gum disease known as gingivitis.

At this stage, brushing and flossing can clear it away. But if plaque is left in place, it can harden into tartar, which can't be removed with regular brushing and instead requires professional cleaning.

As the buildup progresses, bacteria can move below the gumline, forming what's known as a periodontal "pocket"-a deepened space between the teeth and gums. In these pockets, bacteria release toxins that worsen inflammation.

Over time, this can lead to the destruction of gum tissue and even bone loss, a defining feature of advanced gum disease, or periodontitis.

The Simple Habit That Makes the Biggest Difference

Preventing this process, Zinet said, relies on keeping plaque under control every single day.

A 2025 YouGov survey found that 30 percent of Americans brush their teeth at least once a day, while 51 percent brush twice daily and 10 percent report brushing three or more times a day.

Brushing thoroughly twice a day and cleaning between the teeth daily-using floss or interdental brushes-remains the most effective way to remove plaque before it causes harm.

"This is so important because plaque is the root cause of gum disease. One of the biggest challenges is that gum disease is often silent," Zinet said.

"Many patients don’t experience pain and may dismiss bleeding gums as normal, when in fact healthy gums should not bleed."

Signs of Gum Disease

One of the dangers of gum disease is that it can become advanced before people realize anything is wrong. Regular dental check-ups-at least once a year-can help catch problems early and prevent progression.

The CDC has shared the following symptoms to look out for:

• Red, swollen, or tender gums
• Bleeding gums
• Gums that have pulled away from the teeth
• Loose or sensitive teeth
• Pain when chewing
• Changes in the way teeth fit together when biting
• Changes in how well dentures fit

Why Early Action Is Key

The good news is that in its early stages, gum disease is "often reversible," according to Zinet.

"But once bone and supporting tissues are lost, the damage can be permanent, leading to tooth loss," she said. "Consistent daily plaque control therefore remains the most effective and evidence-based way to protect gum health and prevent more serious problems in the future."

If left unmanaged, gum disease doesn't just affect the mouth. The infection can lead to loose teeth or tooth loss and has also been linked to a higher risk of other chronic health conditions, including cardiovascular disease.

In other words, taking a few extra minutes each day to remove plaque could do far more than just protect your smile-it may help safeguard your overall health, too.
