Hello There are 2 ways crooked teeth can be aligned. 1st is having braces (which you don’t want to do ) called orthodontic correction.2nd is prosthetic correction which involves crowns bridges and laminates( putting artificial caps ). Both have their pros and cons and not all the patients can ideally avail these services . The dentist has to first analyse your case which involves lot of factors like your bite ,eating habits ,and parafunctional habits etc.. I will suggest meet a dentist in person for best advice .

if you feel your teeth are badly positioned and you want to correct them and have a beautiful smile then you ought to get it corrected with braces. there are tooth coloured braces available and also clear aligners which offer aesthetic and you need not worry about the metallic smile. consult an orthodontist and get them corrected.
