Lost filling. As a temporary measure, stick a piece of sugarless gum into the cavity or use an over-the-counter dental cement. See the dentist as soon as possible.
Lost crown. If the crown falls off, make an appointment to see the dentist as soon as possible and bring the crown with you. If possible, slip the crown back over the tooth. Before doing so, coat the inner surface with an over-the-counter dental cement, toothpaste, or denture adhesive, to help hold the crown in place. Do not use super glue!
Broken braces and wires. If a wire breaks or sticks out of a bracket or band and is poking your cheek, tongue, or gum, try using the eraser end of a pencil to push the wire into a more comfortable position. If you can't reposition the wire, cover the end with orthodontic wax, a small cotton ball, or piece of gauze until you can get to your orthodontist's office. Never cut the wire, as you could end up swallowing it or breathing it into your lungs.
Loose brackets and bands. Temporarily reattach loose braces with a small piece of orthodontic wax. Alternatively, place the wax over the braces to provide a cushion. See your orthodontist as soon as possible. If the problem is a loose band, save it and call your orthodontist for an appointment to have it re cemented or replaced.
"Having the dental emergency remedied immediately makes for less pain in the mouth and the wallet" Dr. Cherukuri says from her Chino, California practice.
