Common Problems

When it comes to orthodontic treatment, there are a few common problems that we treat. You may suffer from more than one of these problems - don't worry this is common! 

Explore these examples of these common problems below, such as crowding and protrusion. You can also see these problems treated in our patients in our before and after gallery.


Crowding occurs when teeth have insufficient room to line up within the jaws.  Mostly the jaws are perfectly normal size - there is just an inherited mismatch between the size of the teeth and the size of the jaws.  Crowding is normal and occurs in a high percentage of the population.


The appearance and function of your teeth are impacted by upper front teeth protrusion. It is characterised by the upper teeth extending too far forward or the lower teeth not extending far enough forward.


In a deep overbite, the upper front teeth extend vertically down over the lower front teeth, sometimes causing the lower front teeth to bite into the roof of the mouth.


Spacing problems may be caused by missing teeth, or they may only be a cosmetic issue.


In an underbite, the lower jaw extends out, causing the lower front teeth to sit in front of the upper front teeth.


Efficient biting is prevented by an openbite, where the upper and lower front teeth do not overlap. Openbite may be caused by habits, such as thumb sucking. It can also be caused by the relationship of the jaws.


In a crossbite, the upper teeth sit inside the lower teeth, which may cause the lower jaw to move to the side when biting and is implicated in asymmetric growth of the jaw.

Dental Midlines not Matched

Dental midlines that do not match are evident when the back bite does not fit and match appropriately. This may negatively impact jaw growth and proper dental function.
