Why an Orthodontic Referral for my 7-year old?

Keeping in line with Why Do My Kids Need X-rays, it seems only fitting to introduce the subject of an orthodontist. I chose to follow the radiograph blog with a related subject I briefly introduced in the blog. Most kids approximately 7-8 years age will be advised to have a radiograph taken: the panoramic image. This is the image I had mentioned in the last blog, used to determine the development and angulations/eruption paths of the permanent teeth. It is a key tool in a pediatric dentist’s treatment plan consideration to determine dental age, cavity treatment options and whether your child is advanced or delayed in the exfoliation process.

Truth is, the panoramic image is also a key radiographic tool for both the pediatric dentist and orthodontist to collaborate and devise a treatment plan for your child to maximize growth and development potentials. I know what you are thinking—"It seems rather young for my 7-year old to be looking into braces, doesn’t it”? Well, let’s clarify that this referral is not met with all children in this age group beginning in braces as you know them. I advise of such examinations with my orthodontic colleagues in hopes that a critical growth period is not missed in aiding for best overall arch and skeletal tooth orientations.

The age group of 7-10 is one of significant changes. Children will have teeth in transition. Some very obviously loose baby teeth with varying eruption levels of eruption of the permanent teeth. Pronounced, serrated edges of the newly erupted, less pristinely white, permanent teeth and non-scalloped gum lines, rather rounded and bulbous, call attention to many parents in a worrisome manner. This is the typical appearance for your young child newly entering what we call the early transitional dentition stage. Some parents are seeing that there appears an opening in the front teeth then their child is fully closed. Others note that there is a gap between their top and bottom arches where it appears that one jaw is significantly shorter than the other. A crossbite may become more evident, be it a full side or a single, front tooth. For all of these visible growth and skeletal variations that may be more evident to a parent now, I provide a friendly reminder that this is truly normal and is the age of orthodontic evaluation precisely to address such variances.

Keep in mind, that some of the referrals might also be for a seemingly nice smile line, but with concern of any clicking, grinding, popping or asymmetry concerning the preserved function of your child’s TMJ. Others might be experiencing breathing/snoring concerns. All of these are in relation to the broad, openness of the integrated arches and the positioning of the tongue. Perhaps your child is struggling with stopping a habit of thumb sucking or tongue thrust. Aside from varying alternatives to aiding in the cessation of a habit, there also exist appliances that are hugely functional in more immediate cessation.

This age group of referral to see the orthodontist generally is in consideration of jaw growth patterns, compromised angulations of permanent teeth as seen on the panoramic image, any habits that may be potentiating a jaw discrepancy, tonsillar/adenoid and tongue posture concerns that may be affecting the arch structures and breathing/snoring intertwined. Most children are prescribed the use of a functional appliance or limited braces. Treatment time is of a shorter duration and maintains an annual assessment into later years to evaluate for comprehensive braces, if needed. The practice of early orthodontic correction also includes the hope to decrease treatment time in the future, if needed.

There also exists a practice of myofunctional therapies, where exercises are used to activate muscles groups (yes, all the cute cheeks, lips and chin are muscles groups!) to correct a soft tissue imbalance to allow more fluid, passive growth potentials of the arches and tongue posturing that might have been stunted by their additional force or compression.

The discussion of all the varying options would be endless. I have selected a few commonly seen images below. These are of the more pronounced clinical observations I would certainly refer for. The appropriate treatment options are not shown, as this is respectfully not my specialty., The determination of treatment options is more complex of a selection process than this forum could erroneously reflect. I leave that discussion up to my orthodontic colleagues. This blog subject calls attention to the reasoning for an early referral and only to show select images of what a parent would recognize as a situation needing treatment.

The first image is that of an isolated crossbite. A single tooth of the top and bottom arches is in incorrect position, compromising the gum line of the lower, more narrow tooth. Isolated cases of a crossbite, may be early signs of further underlying concerns and really should not be overlooked.



This image demonstrates a deep overbite (Class II malocclusion) in which the top teeth fully cover the bottom teeth. Skeletal assessments would be performed using another radiographic image pertinent to an orthodontist, a lateral cephalometric imae (also seen lateral to this, but as an unrelated image).



This image is of an anterior open bite. Your child may develop this based on genetic background or due to prolonged sucking habit once permanent teeth are coming in. You can recognize that the back molars are in occlusion, but there is a gap in the front teeth; an opening. The image below, and the last image, shows an underbite. This is when the lower arch is in a more advanced, forward position than the top arch. It is clinically referred to as a Class III malocclusion.



Happy reading and I hope this helps you better understand why I suggest a visit with my friendly orthodontic colleague. We all share in the interest of best results for your child!
