Take extra care of your mouth during your treatment. Appliances are strong enough to do their jobs but not enough to stand undue abuse and neglect. Avoid chewing pencils and fingernails and eating hard and sticky foods. Outside of the office, you should keep your braces and teeth EXTRA CLEAN with special care at home. On top of that, make sure to visit your dentist every three months for professional cleanings to ensure your treatment goes swiftly and painlessly.
