Updated: Aug 12
September sneaks up fast, and most St. John's parents have the backpack and school supply lists handled well before Labour Day. What often gets pushed to the bottom of the to-do list? The kids' teeth. That's a problem, because a Canadian Health Measures Survey found that 57% of Canadian children aged 6 to 11 have had at least one cavity. Tooth pain is one of the leading reasons school-age children miss class, and an untreated cavity that was manageable in August can become a real emergency by November. If you're looking for a trusted kids dentist in St. John's, using back-to-school season as a trigger to book that appointment is one of the smartest things you can do for your child this year.

Key Insight
Explanation
Book before August ends
Dental offices in St. John's fill up fast heading into September. Scheduling in July or August means you avoid emergency timing and can address issues before the school year begins.
Cavities found in summer should be treated before September
A small cavity treated now is a filling. The same cavity left until December may become a root canal or extraction, plus missed school days.
NL kids under 13 have universal dental coverage
Newfoundland's Children's Dental Health Program covers exams, cleanings, fluoride applications, sealants, and routine fillings for children up to their 13th birthday at no cost.
Dental sealants are worth asking about for molars
Sealants provide a physical barrier on the chewing surfaces of back teeth where food and bacteria most easily accumulate. They are especially effective when first permanent molars erupt around age 6 to 7.
A mouthguard is not optional for contact sports
Custom-fitted mouthguards from a dental office offer significantly better protection than store-bought versions for children playing hockey, soccer, football, or martial arts.
Brushing technique matters more than frequency
Brushing twice daily only works if it is done properly. Two minutes of gentle circular brushing, covering all surfaces, is more effective than quick scrubbing.
Back-to-school season is the ideal orthodontic window
Ages 7 to 12 are the prime time to catch developing bite problems, crowding, and spacing issues before they require more complex treatment later.
Why Back-to-School Timing Matters for Kids' Dental Health
Summer in Newfoundland is short and sweet, and kids spend it eating popsicles, drinking juice, staying up late, and generally doing the opposite of their school-year routines. That is perfectly fine. The issue is that by the time September rolls around, those habits have had months to do their work on young teeth.
The back-to-school window is genuinely one of the best moments in the calendar to reset dental health. Parents are already making appointments, buying supplies, and reviewing routines. Adding a dental visit to that list takes minimal extra effort but pays off in a big way. A child who starts the school year with a clean bill of oral health is less likely to experience a toothache mid-term, less likely to miss school for a dental emergency, and more likely to maintain good habits when a routine is already established.
At Stavanger Dental in St. John's, we see this every year: families who booked their children's checkups in summer come in with smaller, simpler problems. Families who wait until something hurts often face bigger procedures and more disruption to their schedule. Timing matters.
Step 1: Book the Checkup First, Everything Else Second
A professional examination and cleaning is the non-negotiable foundation of this checklist. Everything else, the at-home routine, the mouthguard, the orthodontic consult, builds on what a dentist finds at that visit. Book it first, not after everything else is sorted.
What a Back-to-School Dental Exam Actually Covers
A thorough back-to-school exam goes well beyond looking for cavities. Your child's dentist will assess the health of the gums, check the development of the bite and jaw, look at eruption patterns for permanent teeth, and examine any existing restorations. For children who have not had X-rays recently, updated images can reveal decay between teeth and show the position of developing permanent teeth that are not yet visible in the mouth.
The cleaning itself removes the plaque and tartar buildup that summer's worth of snacks and irregular brushing has left behind. A professional clean also gives the dentist a clear view of the tooth surfaces, which makes it easier to catch early decay before it becomes a cavity that needs treatment.
Pro tip: If your child has not seen a dentist since spring, aim to book their back-to-school appointment in July or early August. Appointment slots fill quickly as families realize in late August that they need to get this done. Calling earlier is always the right move.
Fluoride Treatments and Dental Sealants: Ask Specifically
Professional fluoride applications strengthen tooth enamel and make it more resistant to the acids produced by bacteria and sugar. For children at higher risk of decay, fluoride varnish applied at a checkup is a simple, quick step with real protective value.
Sealants work differently. They are thin protective coatings applied to the chewing surfaces of the back molars, physically blocking the deep pits and grooves where food particles most commonly get trapped. They are particularly effective when first permanent molars erupt, typically around age 6 or 7. Asking your dentist whether your child is a good candidate for sealants at this visit is worth doing, especially if your child has deep grooves in their molars or a history of cavities.
If a cavity is found at the checkup, treat it before school starts. A small cavity that needs a filling today can progress significantly over a semester if left alone, and a child dealing with tooth pain has a hard time concentrating in class.
Step 2: Reset the At-Home Routine Before School Starts
School schedules are genuinely helpful for dental hygiene. When a child has a consistent morning and bedtime routine, brushing and flossing fit naturally into those anchors. Summer, with its flexible hours, often breaks that rhythm. Use the back-to-school transition to rebuild it deliberately.
Brushing: What Actually Works for Kids
Children should brush twice daily, morning and before bed, for two full minutes each time. The bedtime brush is the more important of the two. Saliva production drops significantly during sleep, which means there is less natural protection against cavity-causing bacteria overnight. Going to bed with a clean mouth matters.
For children under three, a smear of fluoride toothpaste the size of a grain of rice is appropriate. For children aged three and up, a pea-sized amount is correct. Younger children need parental supervision during brushing and should not rinse with water immediately after, as letting fluoride toothpaste remain on the teeth briefly maximizes its protective effect.
Pro tip: A two-minute sand timer or a simple phone timer changes the brushing dynamic completely for reluctant kids. Two minutes feels very long when you are watching it. A timer makes the expectation concrete and removes the argument about whether enough time has passed.
Flossing: Earlier Than Most Parents Start
As soon as two teeth are touching side by side, those contact points need to be flossed. Plaque builds up between teeth in a way that no toothbrush can reach. Many parents delay flossing until children are older, but this leaves some of the highest-risk surfaces for decay completely unprotected. Floss picks are an easier option for children who find traditional floss difficult to handle.
For teens, an alcohol-free fluoride mouthwash used after brushing and flossing adds a final layer of protection against decay and gingivitis.
Step 3: Pack a Tooth-Friendly Lunch Box
What your child eats at school five days a week has a direct effect on their cavity risk, and this is one of the most underestimated factors in children's dental care in NL and across Canada. The problem is not just sugar content. It is also frequency and contact time.
Sipping on juice or a sports drink over the course of a morning means the teeth are under near-constant acid attack. A single glass of juice at lunch is far less damaging than the same juice sipped slowly over two hours. That distinction matters when you are packing a water bottle versus a juice box for your child's school bag.
The foods most damaging to children's teeth are not always the most obviously sweet ones. Sticky foods like dried fruit, crackers, and granola bars cling to tooth surfaces and feed bacteria for far longer than a piece of chocolate that dissolves quickly and is rinsed away.
Strong choices for a tooth-friendly lunch box include fresh fruit, vegetables with hummus, cheese, plain yogurt, and water as the primary drink. These foods do not create the prolonged acid environment that sticky or sugary foods do. Drinking water throughout the school day also helps rinse away food particles and neutralize acids between meals.
Step 4: Sort Out Protective Gear for Fall Sports
Fall sports season in St. John's kicks off quickly after Labour Day. Hockey, soccer, football, basketball, and martial arts all carry real risk of dental injury, and a mouthguard is the most effective piece of protective equipment most young athletes are not wearing consistently.
Store-bought boil-and-bite mouthguards offer some protection, but they are often uncomfortable enough that children remove them during play. A custom-fitted mouthguard made at a dental office fits properly over your child's specific teeth, stays in place, allows normal breathing and speaking, and provides substantially better coverage against chipped teeth, fractures, and soft tissue injuries.
If your child is already in orthodontic treatment with braces or an appliance, a custom mouthguard is not optional. Standard mouthguards will not fit properly over braces, and an impact without protection can cause serious damage to both the teeth and the orthodontic hardware.
Ask your dentist at the back-to-school visit whether your child needs a mouthguard and whether a custom-fitted version is appropriate for their sport and their stage of dental development.
Step 5: Use This Window for an Orthodontic Check
Back-to-school season, roughly ages 6 to 12, overlaps almost perfectly with the window that dentists watch most carefully for emerging orthodontic issues. The mix of primary teeth coming out and permanent teeth coming in creates a dynamic situation that benefits from a trained eye.
Early orthodontic assessment does not always mean early treatment. Often it means identifying a developing issue, monitoring it, and planning treatment at the right moment rather than reacting when the problem has become more complex. Crowding, bite problems, jaw development concerns, and spacing issues are all easier to address when caught during the active growth phase than in the mid-teenage years.
At Stavanger Dental, we offer Invisalign as an orthodontic option for appropriate candidates, including teens. If your child is approaching the age where orthodontic treatment might be on the horizon, a conversation at the back-to-school appointment gives you a realistic picture of what is coming and how much lead time you have to plan for it.
Pro tip: Even if your child had an orthodontic check last year, ask again at this visit. Teeth and jaws change quickly during the elementary school years. A situation that was "watch and wait" six months ago may have developed enough that a plan makes sense now.
Understanding Dental Coverage for NL Families
One of the genuine advantages of raising kids in Newfoundland is that provincial dental coverage for children is among the more generous in the country. Understanding what is covered helps families use it properly, and many families are not fully aware of what they are entitled to.
The Children's Dental Health Program
Newfoundland's Children's Dental Health Program provides universal access to eligible dental services for all children up to their 13th birthday. Covered services include examinations every six months, cleanings once every twelve months, fluoride applications, sealants, and routine fillings and extractions. This program covers 100% of these services, meaning families do not face out-of-pocket costs for the core preventive and restorative care their children need most.
For youth aged 13 to 17 whose families receive income support benefits, coverage continues for examinations, fillings, and extractions through the provincial Income Support program.
The Canadian Dental Care Plan
The federal Canadian Dental Care Plan (CDCP) provides additional coverage for eligible residents who meet age and income requirements. Stavanger Dental accepts the CDCP, so families who qualify can use this benefit without having to navigate additional administrative barriers.
If your child is approaching their 13th birthday, now is a good time to verify what coverage will apply going forward and whether your family qualifies for the CDCP or any other available benefits. Planning ahead avoids a gap in care during an important developmental period.
Comparing Preventive Treatments: What Your Child Actually Needs
At a back-to-school dental visit, parents often encounter recommendations for preventive treatments and are not always sure which ones are genuinely necessary versus which are optional extras. Here is a practical comparison of the three most common ones discussed at children's dental visits.
Treatment
What It Does
Best Candidates
Professional Cleaning
Removes plaque and tartar buildup that daily brushing and flossing cannot fully address. Leaves tooth surfaces smooth and polished, which makes it harder for plaque to adhere.
Every child at every visit. This is not optional. It is the foundation of preventive care and is covered under NL's Children's Dental Health Program once every 12 months.
Fluoride Varnish
Strengthens tooth enamel by promoting remineralization and making enamel more resistant to acid attack from bacteria and sugar. Applied quickly and painlessly at the end of a cleaning appointment.
Most children benefit from this, particularly those with a history of cavities, who consume a lot of sugar, or who have recently had orthodontic appliances removed. Covered under the NL provincial program.
Dental Sealants
A thin resin coating applied to the chewing surfaces of back molars, physically blocking the deep pits and grooves where decay most often starts. Works as a barrier rather than a strengthener.
Children aged 6 to 12 whose first permanent molars have recently erupted. Particularly valuable for children with deep grooves in their molars or a strong family history of cavities. Covered under the NL provincial program for eligible children.
The honest answer to "does my child need all three" is: professional cleaning is non-negotiable, fluoride varnish is appropriate for nearly all children, and sealants are highly recommended for children with specific anatomical risk factors. Your dentist can tell you clearly which apply to your child's situation. At Stavanger Dental, we do not recommend treatments that are not clinically indicated, and we explain the reasoning for every recommendation we make.
Frequently Asked Questions
How often should my child see a kids dentist in St. John's?
Twice a year is the standard recommendation for most children, and it aligns with what Newfoundland's Children's Dental Health Program covers. Some children with a higher risk of cavities may benefit from more frequent visits. Your dentist will tell you at each appointment whether the standard six-month interval is appropriate or whether your child's specific situation warrants a shorter recall.
My child's baby teeth will fall out anyway. Do cavities in primary teeth really need to be treated?
Yes, and this is one of the most common misconceptions in children's dental care in NL. Primary teeth hold space for the permanent teeth developing beneath them. An untreated cavity in a baby tooth can spread to adjacent teeth, cause infection, and in serious cases affect the developing permanent tooth underneath. Beyond the structural issue, a child with tooth pain eats poorly, sleeps poorly, and struggles to concentrate at school.
At what age should I bring my child in for a first dental visit?
The general guidance is by age one or within six months of the first tooth appearing, whichever comes first. Early visits are less about treatment and more about establishing a positive relationship with the dental environment, identifying any early concerns, and giving parents guidance on diet, pacifier use, and home care for very young children.
What is the best way to reduce my child's anxiety about the dentist?
Regular visits starting early are the single most effective strategy. Children who see the dental office as a routine, familiar part of life develop far less anxiety than those who only visit when something is wrong. At Stavanger Dental, we offer sedation options for children who experience significant anxiety, and our team takes time to explain what is happening at every step. If anxiety is a concern, mention it when you book so we can prepare appropriately.
Does my child need X-rays at every visit?
Not necessarily at every visit. The frequency of dental X-rays depends on your child's age, cavity risk, and how much has changed since the last set. Children with a higher risk of decay, or those with teeth that touch closely and cannot be checked visually between them, may need X-rays more often. Your dentist should explain the clinical reason for any X-rays recommended at your child's visit.
Is Invisalign an option for school-age children?
Invisalign Teen and other clear aligner systems are available for adolescents once most or all permanent teeth have erupted. For younger school-age children, the first step is typically an orthodontic assessment to identify any developing issues. Treatment timing depends on the specific problem being addressed. Some bite problems benefit from early intervention during active jaw growth, while others are best addressed once permanent teeth are fully in. Ask your dentist at the back-to-school visit whether orthodontic assessment makes sense for your child's age and development.
What should I pack in my child's lunch to protect their teeth during the school day?
Fresh fruit, vegetables, cheese, plain yogurt, and water make up the core of a tooth-friendly school lunch. The key is limiting sticky or sugary foods that cling to tooth surfaces and avoiding sugary drinks being sipped slowly over long periods. An apple is a better choice than a fruit roll-up made from concentrated apple juice because it does not stick to teeth the same way. Water should be the main drink in the school bag, not juice, flavored milk alternatives, or sports drinks.
