When you first get dental crowns, they’re likely to feel a little tight. Over the next few weeks, they probably seem to get looser and looser, until they’re practically falling out of your mouth every time you open it to eat something or speak. How can this be? Constant clenching or grinding of the teeth can cause a crown to become loose. Tooth decay, also known as cavities, can change the structure of the tooth and in turn, will cause the crown to be loose. Any form of trauma can cause a dental crown to become loose. A loose crown can be very unsettling, but it is also a very common problem. Fortunately, if the crown is in good shape, your dentist can easily cement it back in place. The sooner you call your dentist, the better. This is because the dentin underneath the crown is very vulnerable to damage and decay.
What’s the issue with dental crowns?
The short answer is that a crown that doesn’t fit right isn’t a crown at all — it’s just a loose piece of metal with no real connection to the tooth. This means that it’s going to wear away faster and look terrible long before the tooth would have needed to be replaced without the crown. Moreover, it’s a major dental health hazard to keep a crown from falling out or coming loose in the mouth — it can trap food and bacteria in a way that leads to plaque and gum disease. These problems can be especially bad when zirconium is involved.
The harder material wears away the adjacent tooth structure even faster than a gold crown would, and the low coefficient of friction makes it grind down the adjacent teeth at a much faster rate than a gold crown would. This can lead to major problems with bone loss if it isn’t caught and corrected pretty quickly.
Your dentist didn’t fit the crown properly
If you’ve been to the dentist and gotten a zirconium crown, you may have also gotten a lecture about how you have to be careful not to bite too hard with that tooth. This is because the dentist may have tried to fit the crown improperly. This is a common mistake and can cause a crown to come loose.
First, the dentist may have tried to fit the crown too tightly. This will cause the tooth to get softer and the crown to become loose over time. Second, the dentist may have tried to fit the crown improperly. This can make the crown fit too tightly or too loosely. If the crown is too tight, the tooth will get softer over time and the crown will become loose. If the crown is too loose, the crown will become loose over time.
The tooth root is too short for dental crown
If the crown was put on a tooth that still has a decayed root, it may have to be removed at some point. The dentist will likely put a temporary crown on the tooth while the root is being treated. At the end of the treatment, the dentist will put a permanent crown on the tooth. If the tooth regrows its root but the dentist doesn’t put a long enough root in the new crown, the crown will come loose over time.
The tooth has been damaged since your dentist visit
If there was an accident or you suffered trauma to the mouth since your last dental visit, the tooth may have suffered some damage that wasn’t discovered and corrected. This is especially likely if you have a lot of fillings and other restorative treatments. If the dentist didn’t discover and repair the damage, the crown would become loose over time.
Something’s wrong with neighbouring teeth or bones
If there’s a problem with the other teeth or jaw in the mouth, the crown will become loose over time. Examples include teeth grinding, which can cause the other teeth to move around and damage the crown. It can also cause the crown to become loose. Another example is a gum disease problem. If the crown is touching gum tissue that is inflamed and infected, the crown becomes loose over time as the infection advances.
