Parents often wonder what is normal as their child’s smile develops. Baby teeth fall out, adult teeth arrive in stages, and the jaws grow at different speeds. Some irregularities correct on their own. Others benefit from early guidance so that teen treatment is simpler and faster. Here is a parent friendly guide to the orthodontic issues we see most often in children, how to spot them, and when to book a checkup.
Why early checks matter
The Canadian Association of Orthodontists recommends an orthodontic evaluation by age seven. At this age there is a mix of baby and adult teeth, which makes it easier to see how the bite is forming and whether any eruption or growth problems are starting. Early does not always mean early treatment. Many children are simply monitored until the right time. When treatment is needed, catching problems sooner can shorten future care and reduce the need for extractions.
Signs your child should be seen soon
Watch for crowded or overlapping front teeth, persistent thumb or finger sucking, mouth breathing, speech concerns, chewing difficulty, or a bite that looks very deep, very open, or shifted to one side. Uneven tooth wear and baby teeth that fall out very early or very late are also helpful clues.
The issues we see most
-
Crowding and spacing
Crowding happens when there is not enough room for adult teeth to fit in the arch. Spacing is the opposite. Early loss of baby teeth, differences in tooth size, or small jaws can create crowding. Missing or undersized teeth can create spacing. Guided growth, space maintainers, or limited braces can help make room and align teeth as they arrive. -
Overbite and deep bite
Many children have some overbite, where upper front teeth sit ahead of lower front teeth. A deep bite is when upper front teeth cover too much of the lowers. Deep bites can lead to gum irritation or uneven enamel wear. Elastics, limited braces, or bite plates can help correct the relationship as the child grows. -
Underbite
In an underbite, lower front teeth sit ahead of upper front teeth. This can be due to a strong lower jaw, a small upper jaw, or a combination. Early guidance is important here. In many cases, growth friendly appliances and braces can improve jaw relationships and tooth fit. Waiting too long can limit non-surgical options later. -
Crossbite
A crossbite occurs when upper teeth bite inside the lower teeth. It can affect front teeth, back teeth, or both. One sided crossbites can push the lower jaw to shift during closing, which may affect jaw joints and facial symmetry. Palatal expanders and limited braces can correct the bite and help the upper jaw match the lower. -
Open bite
An open bite leaves space between upper and lower front teeth when the back teeth are together. It can be related to habits like thumb sucking or tongue thrusting, or to growth patterns. Habit appliances, myofunctional strategies, and braces can help close an open bite and support stable swallowing patterns. -
Ectopic eruption and impacted teeth
Sometimes an adult tooth erupts off course, or does not erupt at all because it is blocked. Upper canines are the most common adult teeth to become impacted. Careful X-rays, space creation, or a minor procedure to guide the tooth into position can prevent damage to neighboring teeth and make later treatment easier. -
Early or late loss of baby teeth
Baby teeth act as natural space holders. Losing a baby tooth too early can allow neighboring teeth to drift into the space. Losing it very late can trap an adult tooth. Space maintainers, limited braces, or planned extractions can guide eruption and protect alignment. -
Habits and airway concerns
Thumb or finger sucking, extended pacifier use, mouth breathing, and tongue thrusting can change jaw and tooth position over time. Habit appliances, gentle coaching, and coordination with your dentist or pediatrician can protect developing bites and support healthy breathing.
What early treatment looks like
Early or interceptive treatment is short and focused. It might include a palatal expander to correct a crossbite, a space maintainer to hold room for a missing baby tooth, or limited braces to align a few front teeth and improve confidence. The goal is to guide growth and eruption, not to finish every detail. Most children who need early care still have a second phase of comprehensive treatment as teens, but that teen phase is usually shorter and more predictable.
How teen treatment builds on early guidance
Comprehensive treatment typically begins once most adult teeth are present. Options include metal or ceramic braces, lingual braces placed behind the teeth, and clear aligners for teens. Elastics help coordinate the bite. Treatment length varies with the bite and the goals, but many cases finish in about two years. Retainers protect the result through adolescence and beyond.
Helping your child through treatment
Keep hygiene strong with brushing after meals and daily flossing. Choose braces friendly foods and cut firm foods into small pieces. If a bracket or wire rubs, orthodontic wax and warm salt water rinses help tissues heal. Wear elastics exactly as prescribed. With aligners, aim for 20 to 22 hours of wear daily. Staying consistent with simple habits keeps treatment moving and shortens total time.
Frequently asked questions from parents
Will my child need teeth removed
Many children can be treated without extractions if crowding is addressed at the right time. When extraction is recommended, it is to improve long term health, function, and facial balance. Your orthodontist will explain the reasons clearly.
Do expanders hurt
Expanders feel pressure, especially at first. Most children adapt within a few days. Over the counter pain relief and soft foods help during that short window.
Can sports and music continue
Yes. A mouthguard protects braces during sports. Wind instrument players usually adjust quickly. We help with tips and, when needed, small amounts of wax during practice.
How often are visits
Most children are seen every six to eight weeks. Regular visits keep progress smooth and let us coach hygiene and habits along the way.
The bottom line
Orthodontic issues like crowding, crossbite, overbite, underbite, open bite, and impacted teeth are common in children. Early evaluation gives you a roadmap and can make later care simpler and faster. Most kids do very well with short, focused early steps and a well timed teen phase that finishes the job and sets up a lifetime of confident smiling.
