Regrettably, nothing is eternal. This also goes for the best dental crowns. They must be restored every now and then, because of the injury they sustain from grinding and crushing food.

The crowns need to be swapped out even more frequently by people who grind their teeth during sleep. This will smooth down a dental crown, regardless of what it's made from. If you want to avert having your dental crowns wear out early, then you should use a bite guard.

I also suggest to anyone who has a dental crown that they should brush their teeth religiously. A dental crown won't putrefy. But that's not true about the stump that the crown is covering. If you don't brush regularly, remnant food particles will jam into any gap they can locate.

You're lucky if the glue that's holding your dental crown in place is strong. But odds-on, in the long run it will wear away. This happens exceptionally fast if you're a big soda drinker.

When this bonding agent gets eaten away, food gets stuck there. Microbes come quickly and find the food for a feast. When they've eaten their fill, the microbes form plaque. Then they will come across the remnant portion of your tooth root and put all their energies there. Then we can't just fix the problem with a dental crown. You may have to have your tooth root extracted. Or, an implant might be an option.

It's better for you, in a lot of ways, if you regularly brush and clean your teeth. How long can it take to use that toothbrush–60 seconds? And that is a lot more trouble-free and more inexpensive than a new crown.
