Common Orthodontic Problems

Orthodontic problems can occur throughout the course of your life due to the ever-changing nature of your teeth.

Unavoidable actions like biting and chewing can slowly push your teeth out of their proper alignment as well as unhealthy habits such as thumb sucking and tongue thrusting.

Here are some before and after examples of the most common orthodontic problems that you can seek treatment for.




An underbite is when the lower jaw extends outward, causing the lower front teeth to sit in front of the upper front teeth. This is also referred to as a Class III malocclusion or prognathism.



Teeth spacing is a condition that involves your teeth being separated by large gaps. It can occur naturally and is a common occurrence in children. It can also be caused by missing teeth and/or extractions as well as thumb sucking and tongue thrusting. This issue tends to present itself as a gap between the two front teeth.

Upper Front Teeth Protrusion / Overjet


Upper front teeth protrusion, otherwise known as overjet, is characterized by the upper teeth extending too far forward or the lower teeth not extending far enough forward. The appearance and function of your teeth are impacted by this type of bite. Typically, your upper teeth should extend over your lower teeth by about 1 – 3 millimetres.



Teeth crowding or overcrowded teeth occurs when teeth have insufficient room to erupt from the gum. When teeth don’t have this space to emerge, they can press together, moving them out of their proper alignment. Crowding can often be corrected by expansion, and many times tooth removal can be avoided.



A crossbite involves the upper teeth sitting inside the lower teeth, instead of on the outside, when the jaw is closed. This type of bite may cause misaligned jaw growth.



An overbite occurs when the upper front teeth extend out over the lower front teeth. This can sometimes cause the lower front teeth to bite into the roof of the mouth. Most people’s have some form of overbite, but usually it isn’t noticed if it is a less severe case.

Open Bite


An open bite is a type of orthodontic malocclusion in which the upper and lower front teeth do not meet when the mouth is shut, resulting in a gap. Open bites may cause a number of unwanted habits, such as tongue thrusting. Proper chewing is also impacted by this type of bite.

Dental Midlines not Matched


This type of condition is characterised by asymmetry in the centre points of one or both dental arches. It is caused when the back bite does not fit and match appropriately, which may negatively impact jaw and proper dental function.
