9 Things Dentists Might Not Tell You That Could Save You Money

Your dental team is sitting on a treasure trove of insider information—facts you should know but likely haven’t ever asked about. So, we drilled top dentists and hygienists for their most surprising, smile-boosting tips, from smarter brushing tweaks to a TikTok trend they’d love to retire. Here are the insider secrets that make your appointments easier and your smile healthier.

1. Don’t rush to brush

Most of us grew up hearing that brushing immediately after eating protects our teeth. But that’s only true if you’ve had something sticky and sugary like gummy candies.

If you’ve consumed foods or beverages high in acid, like tomatoes, soda or coffee, rushing to brush actually does more harm than good. The reason? “They create an acidic environment in the mouth that temporarily softens enamel, and brushing immediately can wear away this protective layer,” explains M. Diane Melrose, RDH, professor of dental hygiene and clinical dentistry at the Herman Ostrow School of Dentistry of USC.

Her advice: After eating or drinking anything acidic, rinse well with tap water to neutralize acids, then wait 30 to 40 minutes before brushing to give enamel time to reharden.

2. Forget trying for a ‘deep clean’

“I can’t emphasize enough just how important it is to brush gently,” says Melissa Seibert, DMD, a clinical instructor at Creighton University School of Dentistry and host of the Dental Digest Podcast. “I see so many patients with gum recession or with excessive wear on the front of their teeth. And a lot of the time, it’s from brushing too hard.”

A sign you’re applying too much pressure? Bristles fan out as you scrub. “Some electric toothbrushes now give you live, real-time feedback if you’re using excessive force, which can be a helpful tool.”

3. Rethink the risk of X-rays

Anxious about radiation from dental X-rays? Here’s the reassuring truth: “Dental X-rays expose you to a much lower level of radiation than most people assume,” says Frederica M. Mackert, DDS, an assistant professor at Virginia Commonwealth University School of Dentistry.

How low is low? “A set of bitewings is comparable to a short airplane flight,” she says. X-rays are key, as they can reveal early signs of cavities, bone loss, infections and impacted teeth.

4. Skip the UV toothbrush sanitizer

Many ultraviolet (UV) toothbrush sanitizers boast they remove up to 99.9 percent of germs and bacteria, but the truth is, you can save your money. For most people, sterilizing your bristles isn’t necessary. “The mouth isn’t a sterile environment, and it doesn’t need to be,” says Seibert. “The oral cavity naturally contains a balanced microbiome—a community of healthy bacteria that contributes to oral and systemic health, much like the beneficial bacteria that exist in our gut.”

Even more surprising? You don’t need to toss your toothbrush after you’ve been sick. “Simply allow it to air dry for 12 to 24 hours between uses,” advises Seibert. “Most common viruses don’t survive well in dry conditions.”

One exception: if you’re immunocompromised. “In those cases, additional disinfection precautions could be considered, so ask your dentist for guidance.”

5. Don’t DIY your whitners

TikTok influencers may rave about activated charcoal toothpaste for brightening teeth, but it’s smart to pass on this social media trend, says celebrity cosmetic dentistDaniel Naysan, DDS, founder of Bedford Dental Group in Beverly Hills. “Its abrasive properties can erode tooth enamel, making teeth weaker,” he explains.

Even the popular “old-school” DIY whiteners, baking soda and peroxide, are risky. “They can be safe for very limited, short-term use, but they’re not ideal for daily brushing,” cautions Naysan. That’s because baking soda is mildly abrasive, which over time can wear down enamel and make teeth more sensitive. And frequent or high-concentration hydrogen peroxide can irritate the gums, disrupt the oral microbiome and cause tissue sensitivity, he says.

6. See your dentist—not your MD—for mouth concerns

Because your mouth can reveal early signs of oral cancer, it’s smart to give yourself a quick monthly check and look at your mouth, tongue and cheeks. If you notice a red or white patch or sore spot, call your dentist right away.

“Dentists are trained to screen for oral cancer, have the right tools to examine you and can detect tiny changes in oral tissues,” explains Melrose. “That’s vital, since early detection can help save your life.”

7. Keep old mercury fillings in place

Concerned about mercury from silver amalgam fillings many of us got back in the day? You can breathe a sigh of relief. “The amount of mercury vapor released from properly placed amalgam restorations is extremely low—far below levels known to cause harm,” assures Seibert.

What’s more, you’ll lessen exposure by keeping those fillings right where they are. “Mercury vapor levels are highest during removal, not while they’re in place,” she says. And if one needs to be taken out because it’s worn or cracked, dentists use specific safety protocols that minimize vapor release to keep you safe.

8. Break up with your alcohol-based mouthwash

If you save your most thorough brushing and flossing for right before bed, you’re already on the right track. That’s because your mouth dries out while you sleep, making your teeth more vulnerable to decay from left-behind foods. However, if you add alcohol-based mouthwash on top of that for a “doubly clean” feeling, you may be undoing all that good work.

Why? Alcohol rinses dry the mouth even more, which can raise your cavity risk, says Melrose. She recommends ditching the alcohol-based mouthwash altogether and finishing your bedtime routine instead with an alcohol-free fluoride rinse, which helps strengthen enamel and keep teeth protected while you sleep.

9. Reconsider your appointment schedule

That “see your dentist twice a year rule” isn’t a rule at all. “How often you visit depends on your oral health,” says Melrose. “You might need to come in every three to four months if you have gum issues or you’re at higher risk of tooth decay.”

But if your mouth is healthy and you’re diligent with your cleaning routine, you could go seven or eight months between appointments, she says. Ask your dentist what schedule works best for you.
