Dental Crowns: Why do they feel loose?

At some point in your life, you might need dental crowns or “caps.” Dental crowns are artificial teeth that act as a protective outer layer of the tooth, which can prolong the life of your natural teeth. If you have severely damaged or decayed teeth, Dr. Arpit Pathak and the Magic Smiles Dental and Implant Centre team might recommend placing a dental crown as part of restorative dentistry treatment.

Dental crowns look, feel, and function like natural teeth when properly placed. On the other hand, a loose crown can cause more problems than you might imagine. Aside from imperfect dental work, here are six other factors that might cause dental crowns to detach:

1. Physical Trauma

If you take a blow where a dental crown was placed, it can become loose or influence what’s beneath the restoration. For example, physical trauma can loosen the bonding agent. In other cases, the tooth underneath the dental crown can become fractured.

2. Bruxism

Bruxism is the unconscious grinding or clenching of teeth, which are not part of ordinary chewing actions. This condition is not only detrimental to your jaw and temporomandibular joint (TMJ), but bruxism can loosen, crack, and break your dental work.

3. Underlying Tooth Decay

Even though the crown itself cannot experience tooth decay, the underlying tooth can—beneath dental crowns, dentin, tooth root, and other dental structures are still intact. So, if the protected tooth starts to deteriorate along the gumline, the bonding agent that holds the dental crown in place and the tooth begin to break down. Ultimately, the crown will feel loose or even fall out.

4. Chewy and Sticky Foods

Please don’t let a snack dislodge your dental work. Commonly, chewy and sticky foods force dental crowns out of alignment. Sticky candies (like caramels) are especially hazardous since they slowly break the cement’s seal and can yank the restoration off the tooth.

5. Ill-Fitting Dental Crowns

Ideally, dental crowns have adequate size, length, and shape to blend in seamlessly with your smile. The underlying tooth serves as secure seating for a perfectly fitted crown. Once bonded, dental crowns shouldn’t loosen or come off easily.

However, your dental crown might feel like it’s about to fall off if the underlying tooth is inadequate, imperfectly shaped, or simply doesn’t fit. With brand new dental crowns, dentists typically notice a bad fit and take corrective steps before you realize that there’s an issue. Still, if you notice a bad fit with a crown that has been otherwise dependable for an extensive period, that could mean something has shifted, broken, or altered.

6. Older Dental Work

Sometimes, the fit of the crown is not the problem. Almost all crowns are cemented or bonded onto the natural tooth structure. After many years, the cement washes away. Consequently, the crown might loosen or fall off.
