Every August the same reminder goes out from every dental office in the country: book your child’s back-to-school checkup. It’s good advice. But a lot of the reasoning behind it gets repeated without anyone checking it. Here’s the honest version, what the evidence actually supports and what’s mostly marketing.

The scheduling reason is the real reason

There isn’t a clinical argument that late August is a magic window for dental care. Teeth don’t know it’s a school year. The reason to book now is logistical, and it’s a good one: once school, sports and after-school schedules lock in, appointments get squeezed into a handful of after-3pm slots that fill fast. Families who wait until October end up waiting until December.

There’s also a practical benefit to catching a problem before it becomes an emergency. A small cavity found in August is a routine appointment. The same cavity found in November is a toothache, a missed school day and a longer visit.

Sealants: the strongest evidence in pediatric prevention

If there’s one thing worth asking about at a back-to-school visit, it’s sealants. This is one of the few preventive treatments in dentistry with genuinely strong data behind it.

Sealants are a thin resin coating bonded into the deep grooves on the chewing surfaces of the back teeth, the spots where a toothbrush bristle physically can’t reach. According to the CDC, sealants protect against about 80% of cavities in the first two years and continue to protect against roughly 50% for up to four years. Nine in ten cavities in school-age children happen in those back teeth.

The catch: the CDC also found that around 60% of children ages 6 to 11 don’t have them. Sealants are typically placed shortly after the first permanent molars come in, around age 6, and again after the second molars, around age 12. If your child is in that window and doesn’t have sealants, that’s a conversation worth having. They’re quick, there’s no drilling and no anesthetic is needed.

Mouthguards: real protection, oversold numbers

You will see the claim, repeated constantly, that athletes without a mouthguard are “60 times more likely” to damage their teeth. That figure traces back to a single advocacy organization and it does not hold up. Peer-reviewed meta-analyses put the actual increase in traumatic dental injury risk at roughly 1.6 to 1.9 times without a mouthguard.

That’s a much smaller number, and it’s still a good reason to wear one. A roughly doubled risk of a fractured or knocked-out front tooth is meaningful, and the consequences last decades. An avulsed permanent incisor in a 13-year-old isn’t a one-time repair; it’s a lifetime of restorations, and often an implant down the road.

On custom versus boil-and-bite: a custom-fitted guard fits better, is more comfortable and gets worn more consistently, which is most of the benefit. But a boil-and-bite guard that’s actually in the mouth beats a custom guard sitting in a gym bag. If cost is the deciding factor, get the drugstore one and use it.

“Every six months” is a convention, not a rule

This one surprises people. The Cochrane systematic review on recall intervals found high-certainty evidence that, for adults, a six-month checkup schedule produces little to no difference in cavities, gum health or quality of life compared with a risk-based interval. For children and adolescents specifically, the review concluded there simply isn’t enough reliable evidence to say what the optimal interval is.

What that means in practice is that the right interval depends on the individual. A child with a history of cavities, deep grooves, braces or inconsistent brushing may genuinely need to be seen every three to four months. A low-risk child with good hygiene and no cavity history may do fine at longer intervals. We’d rather assess your child and tell you honestly which category they’re in than book everyone at six months because that’s what the postcard says.

A short, realistic checklist

• Sealants on the permanent molars if they aren’t already there.
• A mouthguard for any contact or collision sport, and for basketball and baseball, which cause more dental injuries than people expect.
• Fluoride. Confirm the toothpaste has it, and ask whether a varnish application makes sense.
• An orthodontic look if your child is 7 or older and hasn’t had one. This is a reasonable time for it.
• Any pain, sensitivity or a tooth that “feels weird.” Mention it even if it went away.

Booking

If you’d like to get your family in before the fall schedule fills up, give the office a call or request a time online. If your child hasn’t been seen in over a year, mention that when you book so we can set aside the right amount of time.
