Orthodontic treatment is a way of straightening or moving teeth, to improve the appearance of the teeth and how they work. It can also help to look after the long-term health of your teeth, gums and jaw joints, by spreading the biting pressure over all your teeth.Many people have crowded or crooked teeth. Orthodontic treatment will straighten the teeth or move them into a better position. This can improve their appearance and the way the teeth bite together, while also making them easier to clean.
What is a fixed appliance?
Often, teeth need to be guided more accurately than they can be using a removable brace. So a fixed brace is used. This has brackets and bands which are temporarily stuck to the teeth. A flexible wire joins all the brackets and allows the teeth to be moved. You can't take the appliance out yourself, so it is called a fixed appliance.
Orthodontic braces usually need adjusting every 4 to 6 weeks. Your orthodontist will tell you how often your brace will need adjusting. When treatment is finished the teeth need to be held in position for a time. This is called the ‘retention' period, and the appliances that hold the teeth in place are called retainers.
The retainers hold newly straightened teeth in position while the surrounding gum and bone settles. The retainers can be removable or fixed, depending on the original problem.
