How to Re-Affix a Dental Crown

A dental crown that falls out is a dental emergency, according to "Dental Health Magazine." In many cases, once the crown falls out, you'll experience pain as the sensitive tooth tissue underneath is exposed to varying temperatures, pressure and air. But even if you don't experience pain or discomfort, it's imperative to call your dentist immediately -- your tooth can become weaker and pieces may break off, further compounding your problems. Pending your appointment, you can re-affix a dental crown temporarily using very simple home techniques.

Things You'll Need

Dental Crown Temporary Repair

• 1

  Always clean the loose crown thoroughly before putting it back over your exposed tooth, advises the Columbia University College of Dental Medicine. A toothpick may be used to remove residual cement and other debris inside of the crown, after which a wet cotton swab can finish the cleaning process.

• 2

  Choose the right temporary adhesive. The Columbia University College of Dental Medicine advises three over-the-counter products: tooth cement, denture adhesive or petroleum jelly. These can be applied to the inside of the crown before it's slipped back over the tooth and will generally allow the crown to adhere while you wait for your dental appointment. Use of household glue, such as super glue or rubber cement, is not advised; these are unsafe to put in your mouth and can damage your tooth and your crown.

  Consult with your dentist. If your tooth doesn't show signs of decay, a dentist may simply clean the area and re-affix the dental crown. But if your tooth is severely decayed, you may need a new crown after the decay is removed.
