I need to strengthen my teeth?!

I need to strengthen my teeth?

I am 27, I grind my teeth really bad at night, but I do wear a mouth guard, I have a few of my front teeth bonded, and I only grind the back ones.
I keep wearing away my bonding. What can I do or ask for to help give them a little more strength instead of rebonded which is getting costly?
And just for general healthy teeth?

You may want to consider full coverage or 3/4 crowns for the front teeth if the bonding keeps wearing away. As far as the grinding goes, you probably grind your teeth in the day too & don't realize it. Wear a timer in your pocket & set it for like every hour. When it goes off check to make sure you are not clinching your teeth. Also, toothpaste w/ ACP in it helps to remineralize the teeth. I think it may only be available through the dental office. In my office we sell MI Paste. It has acp in it & is around $22.00 per tube, but it does work.
