I'm 70 and no gaps I do have a couple of crowns though. Wifey was a dental nurse for years and now works as a dental receptionist. Always moaned and me to floss my teeth which I have got used to but hated doing if I'm honest. She tells me most teeth are lost because of gum disease, not going to argue Lol. Because she is on the desk I get appointments that I must keep. We have electric tooth bushes not the posh ones and have to say they do work well.
