Why Are My Child's Teeth Crooked?
Parents often ask “Why are my child’s teeth crooked?”
Unfortunately, there’s no one-size-fits-all answer to this question. Teeth can grow incorrectly for a number of reasons, including but not limited to, genetic influences, jaw growth deformities, patient habits and serious oral conditions.
Genetics and Crooked Teeth
When extra teeth or abnormally large teeth create a malocclusion (crooked teeth or a bad bite), genetics is usually at play. Other inherited traits involve jaws that are too small to accommodate a full set of teeth and misaligned jaws that are not growing evenly.
In most cases, underbites, overbites and crooked teeth are genetic and can’t be avoided, but can be treated. More serious growth problems will warrant early orthodontic intervention, well before all the adult teeth are through.
While genetics play a major part in determining whether a child requires orthodontic treatment, certain early childhood behaviours may also contribute to the development of crooked teeth.
Taking Care Of Baby Teeth
Baby teeth act as space maintainers for future adult teeth. If a child loses a baby tooth too early, the adjacent teeth can drift into the empty space, reducing the space available later when the adult tooth is ready to erupt. Therefore, taking good care of baby teeth is vital if you want to prevent crowding in the adult teeth.
If a baby tooth is lost due to trauma, or extracted due to disease, it is important that you see our Dentist for the placement of a space maintainer to prevent the loss of space.
A thumb sucking habit after the front teeth have erupted can also impact a child’s teeth – pushing the front teeth forward or possibly creating an open-bite. It’s important to note that there are usually no ill-effects from thumb sucking in early childhood and most children naturally give up the habit somewhere between 2-4 years of age. However, if thumb sucking continues past the age of 6 or 7 (when adult teeth are coming through) there can be misalignment of front teeth and narrowing of the upper jaw which will lead to needing jaw expansion plates and braces. It’s therefore very important to break a thumb-sucking habit while the child is still young.
Still unsure why your child’s teeth are crooked?
We recommend children between the ages of 7-10 years visit the No Brace Centre for an assessment. No referral is needed to see our Dentists, and some orthodontic problems can be easily corrected when treated at an early age.
