On their first visit to the orthodontist, some patients are a bit confused and do not know what to do, in fact, you can ask any questions you want to know about straightening your teeth and the problems you want to solve. The doctor will give you a detailed clinical examination. If both the doctor and patient agree that there is a need for treatment, the orthodontist will advise you to undergo further examinations, including taking dental molds, taking the necessary photographs and x-rays, as well as going to the relevant departments for checkups and treatments, and making an appointment for the next follow-up appointment. After studying and analyzing the models and films, the orthodontist will draw up a treatment plan, estimate the course of treatment and the costs required, as well as evaluate the projected results and prognosis of the treatment. Generally, we expect the course of orthodontic treatment to be around 2-3 years, but the actual time taken for treatment varies from patient to patient because of the varying degree of deformity and the cooperation of each patient. As long as you cooperate actively with your orthodontist, follow up with your orthodontist on time, maintain healthy oral hygiene, and protect your aligners from damage and orthodontic parts from falling off, the duration of orthodontic treatment may be shortened.
