There is no single answer to this question. Orthodontic treatment, like any other medical procedure, is about more than the appearance of your smile – it also concerns the health of your teeth. That is why it is important to go into it feeling confident and at ease.
See as many orthodontists as you need to find a specialist you trust. Mutual understanding between patient and doctor is essential for treatment to get off to a good start. The orthodontist you choose should explain the proposed treatment in a way that convinces you, and should make you feel comfortable talking to them, so that you feel free to ask all your questions.
This answer is for general information. Your own case needs an examination by an orthodontist.
