I have my upper front four teeth inside(2-3mm) than normal and the teeth length also high(3-4 mm). lowar four teeth are normal in position but the length is little high as upper teeth(3-4mm). I have little bone loss inside the teeth, as I had gum problem, and I had the gum surgery as well. Now kindly let me know Is the clips are good for straitening and decreasing the length of the teeth. OR do I need to remove front 4 upper teeth and go for crowns. can I decrease the length of the lowwer teeth by cutting.
