Fixed orthodontic appliances are usually worn for 12-18 months, after which they will need to be removed by a qualified orthodontist. During this time, it is important to maintain good oral hygiene habits and to avoid eating hard or sticky foods that could damage the appliances.


There are many different types of fixed orthodontic appliances, and each has its own advantages and disadvantages.

Metal Bracket

The most common type is the metal bracket, which is made of stainless steel or titanium. Metal brackets are strong and durable, and they can be used for a wide range of dental problems. However, they are also quite visible, so they may not be the best choice for people who are self-conscious about their appearance.

Ceramic Bracket

Another type of fixed appliance is the ceramic bracket, which is made of porcelain or composite material. Ceramic brackets are less visible than metal brackets, and they can be matched to the color of your teeth. However, they are not as strong as metal brackets, and they may break more easily.
