On an average, it takes about 18 to 24 months to complete an orthodontic treatment. Some patients may require less than 12 months, but there are also patients requiring up to 3 years of treatment before their teeth reach the desired position. It also depends on following factors: 1. Choice of Braces There are conventional metal braces and ceramic braces available. Self-Ligating braces, metal or ceramic, need fewer adjustments compared to traditional metal braces thus reducing the number of visits to your orthodontist. Efficient tooth movement can be achieved with a shorter treatment time. The treatment is approximately 30 % faster than normal braces. 2. Age Young patients-teens and children, tend to get results faster than adults because their jaws are still growing and the bone is softer, making the teeth easier to move. However this does not mean all adults need to wear braces for two years or more. 3. Severity of the Case Another crucial factor is the severity of your orthodontic problem. Mild spacing/crowding can be fixed in a year or less time while severe cases could take much longer. 3. Patient Compliance The patient needs to follow all instructions provided by his or her orthodontist to ensure a successful treatment. That includes maintaining proper oral hygiene, keeping your dental appointments and use your orthodontic appliance as directed by your dentist.
