Early-Stage Cavities: 5 Ways to Stop and Reverse Tooth Decay

“We hear this question all the time: Can cavities be reversed? The answer depends on how early we catch them! Catching cavities early gives us the best chance to stop them in their tracks. With the right tools and habits, we can often reverse early damage before it turns into something more serious,”
— Dr. Ryan Bakke, Dentist at Neighborhood Dental – Yankton

When most people hear the word cavity, they picture drills, fillings, and dental work. But what many don’t realize is that not all cavities are created equal, and not all require a filling right away. When caught early, it’s sometimes possible to reverse a cavity and avoid more invasive treatment altogether.

At any Neighborhood Dental location, we believe in early intervention, prevention, and educating our patients to take control of their oral health. So let’s talk about how cavities form, when they can be reversed, and what steps you can take to protect your smile.

What Is a Cavity—Really?

A cavity, also known as tooth decay, starts when the outer layer of your tooth (the enamel) begins to weaken from acid attacks. These acids are produced by bacteria in your mouth when they feed on sugars and starches left behind from food and drinks.

In the earliest stage, this process causes something called demineralization—a loss of minerals from your enamel. This often appears as a white spot on the tooth. At this point, the decay hasn’t yet broken through the enamel surface, which means it’s still reversible.

But once the acid wears a hole in the enamel, that decay becomes a full-blown cavity—and at that point, it must be treated with a filling or other dental procedure.

Can Cavities Really Be Reversed?

Yes, but only in the earliest stage of development. If a tooth is starting to demineralize and there is no actual hole or damage to the tooth structure yet, you may be able to reverse it through proper oral care, fluoride treatments, and diet adjustments. That’s why early detection is key—and why we recommend regular dental visits at least every six months.

5 Ways to Help Reverse Early Cavities

What can you do to protect your teeth and possibly reverse early-stage cavities? Here are five dentist-approved steps to strengthen your enamel and halt decay:

1. Use Fluoride Daily

Fluoride is a natural mineral that helps rebuild weakened enamel and can reverse early signs of decay. Use a fluoride toothpaste and ask your dentist about professional fluoride treatments during your next cleaning.

2. Improve Your Brushing + Flossing Habits

Plaque left on your teeth is a breeding ground for bacteria. Brush twice a day for at least two minutes using gentle circular motions and a soft-bristled toothbrush. Don’t forget to floss once a day—especially between your molars where most cavities form.

3. Rethink Your Diet

Sugary and acidic foods fuel the bacteria that cause cavities. To protect your teeth:

• Limit soda, juice, and sticky candies

• Drink plenty of water

• Snack on cheese, apples, celery, and other teeth-friendly foods that help neutralize acids and increase saliva flow

4. Chew Sugar-Free Gum

Chewing gum with xylitol (a sugar substitute that bacteria can’t digest) stimulates saliva, which helps rinse away food particles and remineralize enamel.

5. Schedule Regular Checkups

Even if your mouth feels fine, your dentist can spot the early signs of decay you can’t see or feel. Early treatment can mean the difference between a quick fluoride application and a costly filling down the road.

What Happens If the Cavity Can’t Be Reversed?

If the cavity has already broken through the enamel and formed a hole in your tooth, unfortunately, it’s past the point of reversal. But don’t worry—our team at Neighborhood Dental offers gentle, effective treatment options, including tooth-colored fillings, same-day crowns, and more. We’ll walk you through every step and create a personalized treatment plan to restore your tooth and prevent further damage.

Prevention Is Always the Best Cure

The best way to “reverse” cavities is to never get them in the first place. That means brushing, flossing, eating smart, and visiting your dentist regularly. Another treatment option to help protect against cavities is dental sealants. We love seeing our patients take charge of their health, and we’re here to support you every step of the way.

At any Neighborhood Dental location, we’re passionate about providing expert care with a neighborly touch. With multiple locations across South Dakota and Nebraska, it’s never been easier to find a team you trust with your smile.
