Hello, smile is a very important aspect of facial beauty and hence I can understand your concern for the same. I would advise you to visit an orthodontist (braces specialist) who can discuss with you the various modalities of treatment. Today, apart from the traditional metal braces, there are various other option available including invisible braces. I am sure your orthodontist will help you in deciding the best possible option. All the best.

Eclinical pictures and few X-rays will be required to assess the clinical condition of your teeth and evaluate the level of malocclusion that you have. The least basic requirement would be a clinical picture and it'll be better if you can post one. The treatment options can vary from orthodontic therapy (through braces or clear aligners) as well as short duration treatment protocols like laminates or Metal Fury Zirconia Crowns. The best options applicable in your case and duration of each treatment can be explained only after a proper clinical evaluation. Regards
