Hi , since ur teeth is not aligned in a proper position ur dentist would ve recommended u for the braces . Wearing braces wnt affect ur look. If ur concerned abt looks u cn go for ceramic braces or invisible braces which are quiet costly . And treatment plan might vary from 6 months to 2 years
If braces are recommended by your dentist, it means that your teeth are not in proper alignment. Wearing braces would bring your teeth to ideal position and improve the overall appearance also. The treatment will not damage your teeth in any way. And if you are concerned about the look of wearing metal braces, you have other options like ceramic braces which are white in color n match with your teeth shade. And if cost is not a factor then invisible braces ( invisalign) can be used.
