A dad or mum wrote me final week:
“We brush. We floss. We’ve switched toothpaste. However my child nonetheless retains getting cavities. What are we lacking?”
I’ve heard that query a whole bunch of occasions. It’s at all times requested with the identical mixture of desperation and guilt.
And it at all times results in the identical fact: Cavities don’t simply come from poor brushing. They arrive from each day habits that really feel innocent.
Goldfish crackers. Gummy nutritional vitamins. Mouths that keep open by way of the evening.
In case you’ve completed every thing “proper” and the cavities preserve coming, this electronic mail is for you. Let’s speak about what really makes a distinction.
Let’s begin with the each day multivitamin.
Again within the 90s, we gave our daughters Flintstones nutritional vitamins from Costco. I brushed their tooth each evening and nonetheless noticed that sticky movie clinging to their molars like caramel. They by no means obtained cavities—however a dentist (that’s me) was brushing and flossing their tooth earlier than mattress. Most households don’t have that!
Now the issue is worse. Gummies are in all places—multivitamins, probiotics, melatonin, magnesium. And whereas they appear like a wise alternative, they weren’t designed with the mouth in thoughts.
Your child’s tooth doesn’t care if it’s a gummy vitamin or a gummy worm. It reacts the identical manner.
In case your youngster takes a gummy, right here’s a greater choice: swap to a dental-friendly vitamin like Hiya. I prefer it as a result of it’s sweetened with monk fruit—no sugar, no acidity, and it doesn’t feed the micro organism that trigger cavities or disrupt the oral microbiome. For my eldest granddaughter—who struggled with cavities—this was a recreation changer. She had to surrender her beloved Nordic Naturals gummies, and these made the transition simple.
In case you bear in mind one factor, make it this: A gummy vitamin every single day does extra injury than goldfish crackers as soon as a month.
Now let’s speak about snacks.
We all know juice and soda aren’t nice. However most mother and father are shocked once I deliver up goldfish.
Starchy snacks like crackers and pretzels break down into sugar—they usually stick. They lodge into the grooves of child molars and sit there for hours. That’s the place cavities start.
You don’t must ban snacks. However you do want to consider texture. Ask: will this cling to tooth? Finest strategy to know is to have some your self! Does it follow your tooth?
Higher choices? Moon Cheese which doesn’t stick and is constructed from only one ingredient—cheese. Which means no added sugars, no starches, and nothing that feeds the micro organism behind cavities. Cheese is mineral-rich and helps stabilize oral pH, making it a really tooth-friendly snack. Oh, and might’t overlook my favourite—meat sticks!
An ideal “hack” is chewing xylitol gum in between meals (I like these ones as a result of they’re freed from important oils, which disrupt the oral microbiome). Xylitol doesn’t simply cut back cavity danger—it actively protects in opposition to it. In a single examine, xylitol was proven to inhibit the expansion of micro organism within the higher airway, together with Streptococcus pneumoniae and Haemophilus influenzae. One other long-term examine discovered that xylitol gum helped cut back cavities even 5 years after youngsters stopped utilizing it. And timing issues: analysis reveals the sooner youngsters begin chewing xylitol gum constantly, the stronger the long-term safety. This isn’t nearly avoiding injury—it’s about serving to the mouth keep wholesome by itself. (PMID: 7486925, PMID: 8281565, PMID: 10096456)
Subsequent: respiration.
In case your youngster sleeps with their mouth open, brushing and flossing gained’t be sufficient. Mouth respiration dries the tissues, lowers oral pH, and creates the perfect circumstances for cavities to thrive.
You’ll be able to’t repair this in a single day, however you can begin retraining the physique.
Right here’s what I like to recommend: Throughout TV time, use MyoTape—a delicate, kid-safe tape that encourages lip closure whereas they sit and focus.
Display screen time works nicely as a result of they’re nonetheless, relaxed, and motivated. Respiration by way of the mouth is extra noticeable in that state—and it offers you a quiet second to construct consciousness and introduce a brand new behavior and not using a energy battle.
Begin with 10–quarter-hour. Construct from there.
In case your youngster can’t preserve their mouth closed comfortably, one thing deeper could also be happening. Tongue ties. Enlarged adenoids. A slender palate.
If that’s the case, see a purposeful dentist or airway-focused ENT. They may also help uncover what’s making nasal respiration laborious—and what to do subsequent. You’ll find a supplier by way of the Useful Dentist Listing or the AADSM (American Academy of Dental Sleep Medication) listing. These are nice beginning factors should you’re undecided who to show to.
And eventually: water.
In case your youngster isn’t ingesting a lot water in the course of the day, they’re doubtless not producing sufficient saliva to guard their tooth.
Saliva is your youngster’s built-in protection system. It’s stuffed with minerals that rebuild enamel. It buffers acid. It helps the mouth heal itself. Nevertheless it solely works if the physique is hydrated.
Right here’s what occurs: each time your youngster eats—particularly carbs or sugar—acid ranges within the mouth rise. That acid pulls minerals from the enamel, weakening it. However saliva steps in. It brings again calcium, phosphate, and different minerals to rebuild the enamel. That’s remineralization. And when it really works, it could possibly cease cavities earlier than they begin.
However it could possibly’t work in case your youngster is dry.
When youngsters are dehydrated, saliva slows down. The pH drops. Acid builds. Micro organism thrive. It will get even worse at evening, particularly for mouth breathers. They get up with a dry mouth and no safety.
The repair isn’t fancy. It’s good quaint water. Particularly after meals and snacks, when acid is at its peak. And in case your youngster resists water, give them a particular straw or allow them to pick a water bottle. I really like this flavored electrolyte—it’s non-acidic with a pH of about 6.5, which is near impartial and much safer than many common electrolyte drinks that fall nicely beneath the important pH threshold. Lemon Lime is my favourite taste.
Brushing and flossing matter—however they’re not the entire image.
In case your youngster retains getting cavities, don’t blame your self. Have a look at the each day habits.
The excellent news is: you possibly can shift the sample. One resolution, one behavior, one substitute at a time. That’s how actual prevention works. And it’s how your child’s story adjustments.
Know a dad or mum combating this? Ahead this to them. It is likely to be the primary time they’ve heard a dentist join the dots between on a regular basis habits and tooth decay—with actual options.

P.S. Pictured beneath: real-world testing by the grandkid panel. Nobody’s requested for his or her gummies again. One of many perks of getting a grandpa for a dentist is getting recruited for stuff like this. I used to be genuinely excited to seek out a youngsters’ vitamin made with tooth in thoughts—no sugar and nothing that undoes the work we’re doing to guard their mouths.
