Braces are bonded brackets, arch wires, elastic bands and retainers that move crowded or spaced teeth into a normal position for esthetics, prevention and function.
Excellent oral hygiene is a must during orthodontic treatment. Failure to brush and floss throughly every day may result in tooth decay or gum disease. Foods rich in sugar and snacks should be limited. Regular oral prophylaxis and dental check up at six month intervals or more frequently as needed is neessary to maintain the teeth in good health. It may also become necessary to stop orthodontic treatment short of the desired final result if non-compliance with oral hygiene maintenance causes extensive decay.
