10 Dentist-Approved Cavity-Fighting Habits That Actually Work

Protect your smile with these 10 dentist-recommended habits that help prevent cavities naturally and effectively.

Cavities, also known as tooth decay, are holes that develop in your teeth due to the buildup of plaque—a sticky film of bacteria. When we consume sugary foods and drinks, these bacteria produce acids that erode the tooth enamel, leading to cavities.​


Why Are Cavities a Concern?

Cavities can cause pain, infection, and even tooth loss if left untreated. They can also affect your overall health, leading to issues like gum disease and affecting your ability to eat and speak properly.

So to help you and your loved ones avoid the pain, hassle, and cost of dealing with tooth decay, here are my top 10 dentist-approved tips that actually work to prevent cavities:

1. Brush Twice Daily with Toothpaste

Brushing your teeth in the morning and before bedtime is your first line of defense against cavities. Fluoride, a natural mineral found in many toothpastes, helps rebuild weak spots in your enamel ( the outer & protective layer of your teeth ) before they become full-blown holes. 

If you don’t brush regularly, plaque—a sticky film of bacteria—can harden and turn into tartar, which a regular toothbrush can no longer remove.

Dentist Note: I once had a patient who brushed every morning, but not at night. She was shocked to learn that bedtime brushing is even more important because our mouths produce less saliva while we sleep, giving bacteria more time to do damage.

Question for you: Are you a night brusher, or do you sometimes skip it? Be honest!


2. Floss Daily—Even If You Think It’s Optional

Flossing is not just an “extra” step—it’s essential! Your toothbrush simply can’t clean the tiny spaces between your teeth where food bits and bacteria love to hide. 

If you skip flossing, you’re leaving about 35% of your tooth surfaces dirty. That’s like taking a bath but skipping your back and armpits, lol.

Dentist Tip: I carry floss in my bag. Once, I had mango fiber stuck in my molars during a long drive from Batangas—floss saved my day (and my dignity, lol).

Do you keep floss in your purse or bag? You’d be surprised how handy it is!


3. Limit Sugary Snacks and Drinks

Sugar is one of the main reasons people get cavities. When you eat sugary snacks or sip sweet drinks like soda or milk tea, bacteria in your mouth turn the sugar into acid—and this acid attacks your teeth for at least 20 minutes after you’re done eating. 

Even fruit juices and sports drinks can cause decay if consumed too often.

Quick Insight: One of my patients told me she sipped cola slowly while working all day. Turns out, it’s not just what you drink but how often you sip it that matters. Constant sipping gives bacteria a buffet.

Try this: Can you go one full day without added sugar? Let me know in the comments how it went!


4. Drink More Water, Especially After Meals

Water helps rinse away leftover food and sugars that bacteria would otherwise feast on. 

It also encourages saliva production, which is your mouth’s natural cleaner. 

Pro Tip: After meals or snacks, especially when brushing isn’t an option, just swish and swallow some water—it makes a big difference.

Here’s a thought: How many glasses of water have you had today? If it’s less than 6, time to refill!


5. Visit Your Dentist Twice a Year—Even If Nothing Hurts

Many people wait until there’s pain before seeing a dentist, but cavities don’t always hurt—until it’s too late. 

Regular checkups every six months allow us to spot problems early and treat them before they become big (and expensive). 

Dental cleanings also remove tartar buildup that brushing and flossing can’t handle.

Confession: Some of my adult patients haven’t been to a dentist in 5–10 years! After just one visit, many say, “I should’ve come sooner.” 

We always welcome you warmly—no judgment here.

When was your last dental checkup? If you can’t remember, it’s time to give us a call!

6. Get Dental Sealants for Kids (and Sometimes Adults)

Dental sealants are thin plastic coatings placed on the chewing surfaces of the back teeth. 

These areas have tiny grooves that are hard to clean and are common spots for cavities. Sealants act like shields, keeping food and bacteria out.

True Story: I applied sealants to a 6-year-old’s molars, and 10 years later, they were still cavity-free! It’s like installing rain gutters to keep the dirt out—simple, affordable, and long-lasting.

Do your kids have sealants yet? If not, we’d love to walk you through the painless process!


7. Chew Sugar-Free Gum Occasionally

Chewing gum increases saliva, which helps neutralize acid and wash away food particles. 

Look for gum with xylitol—it’s a natural sweetener that also fights bacteria. Just remember: it has to be sugar-free, or else it defeats the purpose.

Dentist Confession: I’m not a huge gum chewer myself, but after garlic-heavy lunches? You bet I reach for one. It helps my breath and my teeth.

Pop quiz: What’s your go-to flavor—mint or fruity? Share your gum game in the comments.


8. Avoid Smoking and Chewing Tobacco

Tobacco doesn’t just stain your teeth—it weakens your gums, increases your risk of oral cancer, and makes it harder for your mouth to heal. 

Smoking also dries out the mouth, creating the perfect environment for decay and infection.

Real Talk: I once treated a lovely man who thought brushing extra hard could undo the effects of years of smoking. It doesn’t work that way, sadly. But it’s never too late to quit and start fresh.

If you or a loved one is trying to quit, tell us in the comments! We’d love to cheer you on and support you.

9. Teach and Guide Kids (and Teens) with Patience

Kids don’t always brush properly—sometimes they just wet the brush and pretend! 

It’s important to supervise their brushing and flossing until they develop the habit. Encourage them by making brushing fun with songs, stickers, or timers.

Anecdote: I once told a 7-year-old that the “sugar bugs” were dancing on her teeth—and she gasped and ran to the sink. She brushed so hard her dad said she cleaned her gums too! Balance is key, but creativity helps.

If you have kids, what tricks or stories do you use to get them to brush? I’d love to hear and maybe share them with other parents!
