Back-to-School Dental Checkup: Why It Matters
Dr. Cataldo is a Board-Certified Pediatric Dentist (DMD, University of New England; pediatric residency, Tufts University Floating Hospital for Children) and co-founder of Go Smile Pediatric Dentistry & Orthodontics in Pinellas Park, FL.
I'm the orthodontist here, not the pediatric dentist — but every fall I watch the same thing happen. School starts, and within a few weeks the calls come in: a kid with a toothache that's been building all summer, a chipped front tooth from the first week of football, a molar that could've been sealed in June and now needs a filling. Almost all of it was preventable with one appointment. So I asked my wife and practice partner, Dr. Lynne Cataldo — the actual pediatric dentist in this marriage — to lay out what a back-to-school dental checkup should actually do, and why the timing matters more than parents think.
Why This Checkup Isn't Optional
"They're just teeth" is doing a lot of work in that sentence. Here's what the numbers actually say:
51M+
school hours U.S. kids lose to dental disease every year (ADA)
#1
cavities are the most common chronic disease in school-age children
~3×
more likely to miss school when dental pain goes untreated
The American Dental Association puts the lost-school-time figure at more than 51 million hours a year, and cavities as the single most common chronic disease in school-age kids — more common than asthma. A child in pain doesn't raise their hand, doesn't focus, and doesn't sleep well the night before. The American Academy of Pediatric Dentistry is blunt about it: oral health problems interfere with school performance, and dental care is worth the class time it takes. A routine checkup is how you stay out of the emergency-appointment version of this.
What Florida Actually Requires (and What It Doesn't)
Let's clear this one up, because parents ask every August. For a child entering a Florida school, the state requires a physical exam (within the past 12 months) and up-to-date immunizations on the state forms. That's it. Florida does not require a dental exam for school enrollment.
Which is exactly why it slips through the cracks. Nobody hands you a form for it, so it doesn't make the back-to-school list — right up until it becomes a 7 a.m. toothache in October. Our advice: put the dental checkup on the same schedule as the physical. You're already at the "get the kids checked out before school" stage of summer. Add one appointment.
What a Back-to-School Checkup Actually Covers
Here's Dr. Cataldo, in her own words:
"A good checkup is more than 'no cavities, see you in six months.' I'm looking at how the adult teeth are coming in, whether the back molars need sealing, whether a habit like thumb-sucking or mouth-breathing is starting to change the bite, and what's actually happening at home with brushing and snacks. Ten minutes now saves a much bigger appointment later."
Full exam
Teeth, gums, tongue, and soft tissue — checking for decay, early gum inflammation, and anything that changed since the last visit.
Cleaning + fluoride
Plaque and tartar removed, then a fluoride treatment to re-harden enamel. Part of every routine visit.
X-rays, only if needed
Low-dose digital images when there's a reason — a spot between teeth we can't confirm visually, or teeth not erupting on schedule. Not automatic.
Sealant check
Are the back molars sealed? Are the existing sealants still intact? A quick look that prevents most chewing-surface cavities.
Growth + bite check
How the jaw and adult teeth are coming in. This is where a pediatric dentist and orthodontist under one roof earns its keep.
Brushing coaching
Age-specific technique for your child, plus the honest conversation about which snacks and drinks are doing the damage.
Sealants: 20 Minutes, Big Payoff
The chewing surfaces of the back molars have deep grooves a toothbrush bristle can't get into. A dental sealant is a thin protective coating painted into those grooves — no drilling, no numbing, done in a few minutes per tooth. The National Institute of Dental and Craniofacial Research recommends sealing permanent molars as they come in — typically around age 6 for the first molars and age 12 for the second molars.
A back-to-school visit is the natural time to check this: is your child at the age where a molar just erupted and should be sealed? Are last year's sealants still fully intact, or did one chip and need a re-do? It's one of the highest-value few minutes in pediatric dentistry, and it's easy to forget because nothing hurts.
If Your Kid Plays a Fall Sport, Read This
Fall sports season is when we see the chipped and knocked-out front teeth — football and flag football, soccer, basketball, cheer. A knocked-out permanent tooth is a genuine dental emergency, and a chipped front tooth on an 11-year-old is a repair that follows them for decades.
The boil-and-bite guard from the sporting-goods store is better than nothing, but kids hate how it fits and take it out. A custom mouthguard is molded to your child's teeth, so it's thinner, easier to talk and breathe in, and actually stays in. If your child made a team this fall, ask for one at the checkup — we can take the mold the same visit. And if your child is in braces, they need an orthodontic mouthguard specifically — a standard one won't fit over brackets.
When to Book (Hint: Not August)
The single most common mistake is calling in the last two weeks of summer, when every other family is calling too. Book earlier and you get better appointment times, a calmer visit, and — the real reason — runway to fix anything we find.
- 1
Spring
When the report card comes home, call and book the late-summer slot. Best appointment times go first.
- 2
June
Second-best window. Plenty of openings, and any treatment needed can be done at an easy pace.
- 3
2–6 weeks before school
The target. Enough runway to fix a cavity calmly if we find one.
- 4
The week before school
Too late for comfort. If we find something, you're scheduling treatment around the first week of class.
If you have more than one child, ask about family block scheduling — we'll see siblings back-to-back in one visit so it's a single trip and less time off work.
The Home Routine That Keeps It Working
The checkup is 30 minutes. The other 364 days happen at home, and the school year is when routines slip — early mornings, packed lunches, after-school snacks on the counter. Dr. Cataldo's actual list:
Two minutes, twice a day
A pea-sized smear of fluoride toothpaste. Set a timer — most kids (and adults) quit at 45 seconds.
Floss where teeth touch
Wherever two teeth are in contact, a brush can't reach between them. That's where school-age cavities start.
Water in the water bottle
Juice, sports drinks, and flavored waters bathe teeth in sugar and acid all day. Plain water for the backpack.
Snack, don't graze
A treat eaten in ten minutes does less damage than the same treat nibbled over an hour. Timing matters as much as amount.
The Part I Actually Care About
Back to me — the ortho guy. Here's my selfish reason for wanting your kid in that chair every six months: the back-to-school checkup is where a lot of bite problems get spotted early, while they're cheap and simple to guide. A crossbite caught at 7 is a short, easy fix. The same crossbite found at 13 is a longer treatment, sometimes with extractions. Dr. Cataldo flags these at the routine visit and walks you over to my side of the office — same roof, same day, no second appointment across town.
So book the checkup. Put it next to the school physical on the list. Future-you — and honestly, future-me — will thank you.

Frequently Asked Questions
How often should my child see the dentist?
Every six months for most kids — the same rhythm as adults. That schedule lets Dr. Cataldo catch small things (a spot of early decay, a crowding issue, a sealant that needs a touch-up) while they're still small and easy to handle. Some higher-cavity-risk kids come in every three to four months; we'll tell you if that's your child.
Does Florida require a dental exam for school?
No. Florida requires a physical exam and up-to-date immunizations for school entry, not a dental exam. But the checkup is still worth doing on the same schedule as the physical — cavities are the most common chronic disease in school-age kids, and dental pain is one of the most preventable reasons a child misses class.
My child had a cleaning in the spring. Do they need another one before school?
Only if six months have passed. If the spring visit was in April or May, you're fine until the fall. If it was back in January or February, booking a late-summer visit puts them back on a six-month cycle heading into the school year — which is the whole point.
What if the checkup finds a cavity right before school starts?
That's exactly why we say don't wait until August. If we find something, we want time to treat it calmly before the first week of school, not squeeze it in around it. When timing is tight we prioritize school-age kids and do same-day treatment whenever the schedule allows.
Can you see all my kids in one appointment?
Yes. We offer family block scheduling so siblings are seen back-to-back in a single visit — less time off work for you and one trip instead of three. Tell us the ages when you call and we'll build the block.
Do you make sports mouthguards for kids?
We do — custom-fitted ones, not the boil-and-bite kind from the sporting-goods store. A custom guard fits better, so kids actually keep it in, and it protects against the chipped and knocked-out front teeth we see every fall from football, basketball, and soccer.
My kid is terrified of the dentist. What then?
Tell us when you book so we can plan the visit around it. Dr. Cataldo paces these appointments around the child getting comfortable, not around a checklist, and we have sedation options for kids who need more support. A nervous first visit handled well is what makes the next seventeen years of visits routine.
What if we don't have dental insurance?
We offer the GO Smile Savings plan for uninsured families, which reduces rates on exams, cleanings, sealants, and treatment. Ask our team about enrollment when you call to book.
