The benefits of orthodontics can include:
correction of dental crowding and straightening of your teeth
correction of your bite so the front and back teeth meet evenly
reducing the chance of damage to prominent teeth
improving your appearance, including your smile
Many people have crowded or crooked teeth, or their teeth don’t meet correctly when they bite. These problems can mean the teeth are more likely to become damaged or put a strain on jaw muscles.
In some cases, abnormal development of the teeth and jaw can affect the shape of the face.
