How can I find out if I need braces?

Consult your dentist and ask for an assessment. Many ordinary dentists have received additional training in orthodontics and have chosen to incorporate it into their practice.
 
Depending on the complexity of your case and whether or not your dentist performs orthodontic work, he or she may choose to treat you or refer you to an orthodontist who specializes in diagnosing, preventing, and treating dental and facial irregularities. In addition to a four-year dental graduate program, orthodontists also completed two or three years of advanced orthodontic advanced education.
 
Most preliminary consultations provide an opportunity to ask questions about orthodontic treatment, such as:
 
What is the cost involved?
How can braces correct my problem?
How often do I need to wear a braces?
What is the dentist's experience with my particular problem?
Can I arrange an appointment at a convenient time? If possible, obtain references from current or previous patients.
