Quick Answer
In a backcountry emergency, if a tooth cracks, stabilize the tooth with dental cement, cover it with a temporary filling, and seek dental care as soon as possible.
Assessing the Damage
When a tooth cracks, assess the extent of the damage. If the crack is shallow, you might be able to repair it with dental cement. However, if the crack is deep or involves the nerve, extraction or root canal may be necessary. If you have a multi-tool or pocket knife, use it to clean out any debris from the crack. Apply a small amount of dental cement to the cracked area and shape it to fit the tooth’s contours.
Temporary Fix
To create a temporary filling, apply a small amount of dental cement to the cracked area and press a cotton ball or a small piece of gauze into the hole. Secure the cotton or gauze with dental floss or a small amount of dental cement. This will help stabilize the tooth and prevent further irritation. If you have a temporary filling kit or a tube of tooth filling, use it according to the instructions.
Stabilizing the Tooth
If the crack is severe, the tooth may be loose. Use a dental splint or a piece of gauze to stabilize the tooth. Apply a small amount of dental cement to the back of the tooth and press the gauze or splint against it. Hold the tooth in place for a few seconds to set the cement. This will help keep the tooth in place until you can seek dental care. Remember to rinse your mouth with water and apply a topical anesthetic to reduce any pain or discomfort.
