How to Replace a Tooth Crown Yourself

Tooth #18 image by Jeffrey Sinnock from

Dentists create crowns for teeth that have been broken, cracked or otherwise damaged beyond the repair capabilities of surface bonding.

Crowns are generally sturdy and can last for years, but the basic attachment process involves cementing the crown to the original tooth, which makes the crown susceptible to falling off or being pulled off by sticky foods. If the original tooth does not get damaged, a temporary fix can prevent further pain and discomfort until a dental professional can be seen.

Numb the pain that may occur with a commercially available pain reliever. Biting down on something hard, or having sticky food pull the crown off may cause pain and/or discomfort which should be relieved by aspirin, acetaminophen or ibuprofen before tampering with the area to replace the crown.

Clean the area where the crown will sit with toothbrush and floss. Make certain that there is no food debris on the original tooth surface or on the crown. Use a warm salt water rinse to flush the mouth and tooth area, while preparing the crown for reinsertion.

Spread the bonding material inside of the crown. Some sealant kits require mixing the bonding material, while other emergency tooth repair kits come with the adhesive already mixed, using the same material dentists use to repair

Dry the original tooth surface, using cotton or gauze. Place cotton or gauze between the tooth and the jaw to keep the tooth as dry as possible.

Press the crown back onto the tooth. Bite down with just enough pressure to hold the crown in place. Don't apply too much pressure, because a change in the way your teeth come together could have caused the crown to pop off in the first place.
