Yes, dental crowns can fall off, although it is not a common occurrence. Crowns are typically cemented or bonded to the tooth and are designed to stay in place for many years. However, there are several reasons why a dental crown might fall off:
-
Decay Under the Crown: If the tooth beneath the crown becomes decayed, the bond may weaken, and the crown may loosen or fall off.
-
Wear and Tear: Over time, especially with heavy biting or grinding, the materials holding the crown in place may wear down. This could cause the crown to become loose or dislodged.
-
Improper Fit: If the crown was not properly fitted or if the tooth structure beneath it was not prepared correctly, the bond could fail, causing the crown to fall off.
-
Age of the Crown: Crowns do not last forever. After many years, the cement or bonding agent may lose its effectiveness, increasing the likelihood of the crown falling off.
-
Trauma or Injury: A blow to the mouth or any significant impact can cause the crown to loosen or even fall off.
-
Poor Oral Hygiene: Failure to maintain good oral hygiene can lead to plaque buildup and decay under the crown, which can ultimately cause it to fall off.
If a crown does fall off, it’s important to see a dentist as soon as possible. In many cases, the crown can be re-cemented. However, if the crown or the tooth beneath it is damaged, additional treatment may be required.
