What are fixed orthodontic appliances (braces)?

Teeth in your upper and lower jaws form two arches, which can form an 'even curve' or can be outside the average/normal alignment.

The fixed appliances that your orthodontist attaches to your teeth allow gentle but continuous forces to be applied to the teeth to move them into or along the arch. The aim of their use is to achieve better positions of the teeth.

How long will I have to wear a fixed appliance?

Your orthodontist will be able to advise you of how long it will take to move your teeth into the best alignment. This will depend on the type of treatment and also how quickly your teeth move. It is not a good idea to move them too fast - this can damage your teeth. Often, people wear appliances for between one and two years.

Why do I need jaw surgery combined with orthodontics?

Orthodontics aims to correct the alignment of the teeth to improve the function of the teeth and jaws as a chewing system and also to improve the general facial appearance. This straightening of your teeth is, however, sometimes limited by the (size and) position of the jaws in which the teeth lie.

When the teeth cannot be aligned by orthodontics alone, you might be offered orthognathic surgery, which is the correction of one or both jaws by surgery. This has the aim of changing the (size and) alignment of the jaws, which can allow the teeth to be positioned better.

If this type of surgery is likely to benefit you, your dentist/oral surgeon will discuss the options that are available.
