I am in the process of having two of my crowns replaced - I am 67. The original crowns are over 25 years old and, as happens to us all, my gums had started to recede and it looked as though there was a big black line across the top of these two teeth (they were my front two teeth). To compound the look, I have two implants on either side of these front teeth which are flush to the gum, emphasising the bad (now) fit of the crowns. I have the temporary ones in at present and they have made such a difference - the final crowns being put in next Tuesday. I am very pleased so far and deem it money well spent (although I have (and have had for many years) a dental plan policy which will help towards the cost. No matter how old you are, if its bothering you and you can afford it, I would say go for it - it will make all the difference in looks and make you feel a lot happier about yourself. Good luck
