Can a crown fall off?

Yes, a dental crown can fall off, although this is relatively uncommon with properly fitted and well-maintained crowns. If a crown does come loose or falls off, it is usually due to one of several factors. These can include a lack of sufficient cement used during the initial placement, decay developing under the crown that weakens the bond, or damage to the crown itself from trauma, teeth grinding, or biting on something hard. In some cases, the underlying tooth structure may also have changed, causing the crown to lose its fit. If your crown falls off, it’s important to contact your dentist as soon as possible to have it re-cemented or replaced. In the meantime, avoid chewing on the affected side and try to keep the area clean. Your dentist will assess the situation, determine the cause of the issue, and provide the appropriate treatment to restore the crown.
