A temporary crown is a tooth-shaped cap that covers and protects the natural tooth until a permanent crown is made and cemented into place.
Because dentists typically attach temporary crowns with temporary dental cement, extra care is required to prevent the loosening of the crown.
If your temporary crown falls out during your dentist’s regular business hours, call your dentist’s office to have it re-cemented or remade. If the crown falls out after hours, during vacation, or when you cannot reach your dentist, don’t panic. The situation is not urgent as long as you are not in pain.
In case of a temporary crown falling out, do the following:
If your temporary crown is damaged and creates a jagged edge in your mouth, you can place orthodontic wax over the tooth. Orthodontic wax is available at any drugstore.
Losing your temporary crown is typically not a dental emergency that requires urgent treatment. However, you should return to the dentist within a day or two after losing the crown. The dentist might need to replace the temporary crown to avoid damage to the underlying tooth or to prevent fitting problems with your permanent crown.
If your temporary crown is in place to protect a cracked tooth, to insulate a tooth following a root canal, or to save a decayed tooth that cannot hold a filling, replace your crown as soon as possible. A crownless tooth can deteriorate quickly and worsen preexisting tooth damage.
Proper dental care is essential to prevent a temporary crown from falling out. Avoid chewing gum or eating sticky foods that could loosen your temporary crown.
You should also avoid sugary foods. Your temporary crown may have a small gap between the crown and gum line. This means sugar can reach under the crown and cause decay or sensitivity.
Foods to avoid while you have a temporary crown include:
Practicing proper dental hygiene will prevent decay and gum problems around the crown. Brush gently around the tooth and gum line twice daily using toothpaste. You can also opt for a toothpaste that targets sensitive teeth.
Flossing is recommended for temporary crown care. However, you must floss down and out instead of down and up to avoid dislodging the temporary dental crown.
If your temporary crown falls off despite these precautions, contact your dentist so they can recement the crown or create a new one to prevent future problems.
The essential steps to take when your crown has fallen out include:
If your temporary crown falls out, do not swallow it.
Temporary crowns are more delicate and fragile than permanent ones. Though the crowns are designed to stay in place for a few weeks, they can loosen up earlier than expected.
The causes of a prematurely loose temporary crown include:
If a dental crown is on the tooth longer than a dentist recommends, decay can change the underlying tooth structure and cause the temporary crown to dislodge.
