Successful orthodontic treatment requires more than the orthodontist’s skill. It requires cooperation among patient, parent and orthodontist. Certain phases of orthodontic treatment are impossible unless the patient diligently follows instructions such as wearing elastics or removable appliances. Teeth and gums must be brushed and flossed carefully and frequently during orthodontic treatment. Broken or cancelled appointments during orthodontic care may prolong treatment and have a detrimental effect upon the results.
