common problems with children's teeth

Is there a way to tell if your child has orthodontic problems? The best thing to do is to bring them in for a check-up from the age of 7. You can also keep an eye out for a few common issues that could develop as your child grows.  Keep in mind that some developing issues may be apparent only to a trained and experienced orthodontist.

Common Children’s Orthodontic Problems

Abnormal Eruptions

An abnormal eruption happens when a tooth starts emerging through the gum but in the wrong place. If a tooth can’t fully grow in, a small surgical procedure may be necessary to uncover it to prevent further problems down the track. This can be diagnosed and coordinated by your orthodontist (a gum specialist may also be involved).


Crowding happens when there’s not enough space for teeth to fit normally in your little one’s jaws. It could be because the jaws are too small, or the teeth are too big. There are many possible solutions depending on the stage of your child, some may include early intervention that may reduce the need for treatment later.


A crossbite occurs when one or more of your child’s upper teeth bite inside their lower teeth. It’s usually a result of a misalignment of the upper and lower jaws. In children, widening the upper jaw with a palatal expander could help solve what is one of the most common orthodontic problems we see.

Too Much Space

Excessive space can happen when the teeth are small relative to the available jaw size, or when one or more teeth just don’t grow in or is lost to disease or trauma.


Underbites are the result of the lower front teeth extending past the upper front teeth. A common cause for an underbite is caused by either an undergrowth of the upper jaw or overgrowth of the lower jaw. Depending on the extent of your little one’s orthodontic problems, treatment may involve jaw surgery.  The good news is the earlier this is diagnosed, the greater the chance that relatively simple early intervention will alleviate the need for surgery.


A deep bite is a ‘vertical’ problem where your child’s upper front teeth bite way far down over their lower teeth. The bite can be so deep that the upper teeth completely cover the lower teeth. This can cause excessive dental wear, and may even cause discomfort and other dental problems as the lower teeth bite up into the roof of the mouth.

Increased Overjet

Another type of overbite is a ‘horizontal’ problems which is the opposite of the underbite described above.  Orthodontists usually call this an increased ‘overjet’ where the top teeth are ahead relative to the bottom, leaving a horizontal gap between upper and lower teeth.

Open bite

Another type of ‘vertical’ problem; this time opposite to the increased vertical overbite.  This is where the front teeth remain ‘open’ at the front whilst the back teeth are touching.  This can sometimes be caused by a thumb sucking habit or a tongue posture issue.
