Sorry to say, nothing is eternal. This also pertains to dental crowns. They will also need to be replaced every so often, because of all the wear and tear you put on them chewing up your meals.

The crowns have to be exchanged time and again even more by people who grind their teeth during sleep. This will whittle down a dental crown, no matter what it's made from. If you're interested in avoiding being forced to replace your dental crowns, then I would recommend a bite guard.

Plus, I also tell all of my patients with a dental crown that they need to brush their teeth even more often than usual. A dental crown won't get moldy. But what will rot out is the base of the tooth that it covers. If your toothbrush has dust on it, your dinner remains will crawl into any little gap that's available.

Bravo to you, if the crown cement your dentist used is strong. But odds-on, it will corrode in time. This is chiefly the case if you drink a lot of soda or alcoholic beverages.

When this cement wears away, particles of food fill up the hole. It won't be long before microbes feast on the food. When they've gorged themselves, the microbes form plaque. After that, they find what's left of your tooth root and get started there. Then, you might need more than a dental crown. It's possible that you might need to have that root extracted. Or I might suggest an implant.

You're at an advantage, in a lot of ways, if you keep your teeth brushed well and clean. How long can it take to clean your teeth–a minute or two? And that's a whole lot easier and doesn't cost as much as getting a new dental crown.
