Hi there Sadkitty!
All of my life my 2 front teeth overlapped eachother & I never smiled because I hated it sooooo bad & my parents would never take me to the dentist to see about getting them fixed!
Well....I ended up beong a dental assistant years later & the Dentist that I worked for was able to put PV's on my front 2 teeth & I LOVE THEM!
It all depends on your bite if you are able to get them on your bottom teeth. When you bite down & your bootom teeth touch the back of you top teeth then NOPE it will not work there!
Check with your dentist & find out your options! My bottom teeth are crooked but as good as my 2 front teeth look now bar far makes up for the bottom ones! I can live with those! (you can not see them anyway)
Keep us informed on what you end up doing!
Good luck!
