A dental crown is a custom-fitted cap placed over a damaged tooth to restore its shape, size, strength, and appearance. It encases the entire visible portion of the tooth, providing protection and improving chewing function. While crowns are designed for durability, they can become loose or dislodged. Knowing what to do if a crown falls off helps protect your tooth and facilitates its prompt restoration.
Immediate Steps After a Crown Falls Off
If your dental crown falls off, carefully retrieve it, ensuring you do not swallow it. Gently clean the crown with warm water to remove debris or old cement, avoiding harsh scrubbing or chemicals. Inspect the crown for damage (cracks, chips) and the exposed tooth for sharp edges or structural changes.
To protect the exposed tooth, which may be sensitive, use temporary dental cement from a pharmacy. Apply a small amount inside the crown and carefully re-seat it, ensuring proper alignment before gentle pressure. If the crown is damaged or doesn’t fit, cover the tooth with dental wax or sugar-free gum for temporary protection until you see a dentist. Store the crown safely and contact your dentist as soon as possible. Never use household glues or superglue, as these are not safe or effective for dental use.
Factors Determining Reattachment and Dental Solutions
Reattaching a dental crown depends on several factors a dentist evaluates during your appointment. An intact, undamaged crown without cracks or significant wear is a good candidate for re-cementing. However, a fractured, chipped, or worn crown may not provide adequate protection and will likely need replacement.
The underlying tooth’s health and structure are equally important. Dentists check for decay, fractures, or insufficient tooth structure. Minor decay can be removed and the crown re-cemented, but extensive decay or a fractured tooth may require a new crown or other restorative procedures. The reason for dislodgement (old cement, new decay, or excessive biting forces) also guides the dentist’s decision. If reattachment is feasible, the dentist cleans the tooth and crown thoroughly, then bonds it back into place using strong dental cement.
If reattachment isn’t possible due to crown or tooth damage, alternative dental solutions exist. A new dental crown, custom-made to fit the prepared tooth, is a common option. For severe damage or extensive tooth loss, a dental bridge might replace missing teeth by anchoring to adjacent natural teeth or implants. If the tooth cannot be saved, a dental implant (a surgically placed post supporting a new crown) offers a durable replacement.
Caring for Your Dental Crown
Good oral hygiene is fundamental to preserving your dental crown and preventing future issues. Brush your teeth at least twice daily with a soft-bristled toothbrush and fluoride toothpaste. Floss daily to remove plaque and food particles, especially at the gumline, where decay can compromise the crown’s seal.
Avoiding certain foods can extend the life of your crown. Hard candies, ice, and sticky items like caramels can dislodge the crown. If you grind or clench your teeth (bruxism), your dentist may recommend a custom-fitted nightguard to protect your crown and natural teeth. Regular dental check-ups and professional cleanings are important for monitoring the crown’s condition and surrounding tooth health.
