Sorry to say, nothing is eternal. This also pertains to dental crowns. You will need to have a new one put in from time to time, because of all the wear and tear you put on them biting down on them during meals.

The crowns must be traded out even more often by those who grind their teeth. This will even out a dental crown, no matter the material used to make it. If you're interested in preventing premature dental crown replacements, then I would recommend a bite guard.

I also advise all my patients who have dental crowns that they need to brush their teeth even more often than usual. Dental crowns don't waste away. But that isn't the case with the stump that it's shielding. If you do not brush your teeth, remnant food molecules will attach themselves to any gap they can locate.

Congratulations if the glue that's holding your dental crown in place is long-lasting. But most likely, in the long run it will wear away. In particular, this is true if you drink a lot of pop or alcohol.

When this bonding agent is no longer there, food particles get jammed in the hole. Microbes come quickly and find the food for a feast. When they're done eating, the microbes form plaque. Next, they will find the remaining portion of your tooth root and turn that part of your mouth into their personal playground. You will likely be in need of more than a dental crown when they're done. You may have to have your tooth root extracted. Or, I might advise an implant.

You'll be much farther ahead, by my calculations, if you make it a point to keep your teeth clean. How long can it take to use that toothbrush–the length of a couple of commercials? And that is a lot more uncomplicated and cheaper than getting a new crown.
