Orthodontic treatment is used to correct a 'bad bite'.
Bad bite - also called malocclusion - occurs when teeth are crowded or crooked.
Sometimes teeth may appear straight but, because the upper and lower jaws do not meet properly, you can have an uneven bite.
Jaw problems and teeth that are protruding, crowded or irregularly spaced can be inherited or may be caused by factors such as accidents or losing teeth prematurely.
Orthodontic treatment leads to a healthier mouth - and an important additional benefit is that it makes you look better by giving you a better smile.
When teeth are crowded or crooked, it is more difficult to clean the mouth properly.
This can lead on to tooth decay, gum disease and even loss of teeth.
When you have an improper bite, chewing and speaking can be more difficult.
This can cause abnormal wear to tooth enamel and can lead to problems with the jaws.
Orthodontic treatment can therefore lead to improvements in your health as well as making you look and feel better.
