Quick Answer

Super glue forms a permanent bond, notes Dr. Bohle. If the fragment does not have the correct placement, a dentist must perform major corrective work. Dentists can dissolve the super glue if necessary, but the solvent itself is toxic.

Glue that gets into the dentin tubules of the tooth can kill the tubules, causing damage inside the tooth. Sometimes this damage is repairable with a root canal, but it's possible for damage to be so severe that the tooth requires extraction. In addition to oral damage, super glue fumes can cause reactions in some people, notes Smile Columbia Dentistry.

If a patient breaks a tooth, he should see a dentist as soon as possible, advises WebMD. In the meantime, he can take over-the-counter remedies for pain, cover sharp edges with sugarless gum or paraffin, and avoid chewing with the broken tooth.
