Answer: Well you could start out by flossing more. You can show her you care by creating an essay or power point of the pros and cons (That has worked for me) And you could get a dentists opinion. You could also let her take a good look at your teeth so she can see why you really want them. Braces are very expensive so maybe you could save up and offer to help pay for them. Let me know if I helped by marking brainliest or commenting!
