Unfortunately, nothing good lasts forever. That also applies to the very best dental crowns. Even they need to be replaced every now and again, because of the stress you cause while chomping on food.

The crowns need to be replaced over and over again by people who grind down on their teeth while they sleep. This will level out a dental crown, regardless what material is used to make it. If you're interested in avoiding having your dental crowns wear out early, then I would recommend a bite guard.

I also tell all people with a crown that they should brush their teeth regularly. A dental crown won't get moldy. But that isn't the case with the stump that it's shielding. If your toothbrush has dust on it, remnant food molecules will attach themselves to all the crevices they can.

Congratulations if the bonding under your dental crown doesn't waste away easily. But almost certainly, sooner or later it will waste away. This happens exceptionally fast if you spend your days imbibing soda or alcohol.

When this cement gets worn down, food particles will stick to it. It won't be long before microbes feast on the food. When all the food is gone, they manufacture plaque colonies. Then they start in on your tooth root and make that their focus. When they're through, you'll probably need more than a dental crown. I might have to take out the whole root. Or, an implant might be an option.

You'll be much farther ahead, by many standards, if you keep your teeth brushed well and clean. It doesn't take forever to use that toothbrush–a minute or two? And that is a lot more uncomplicated and cheaper than getting a new crown.
