Common First-Aid Procedures for a Lost Tooth

Losing a tooth does not necessarily signify that it cannot be reinserted back into the mouth. If the proper procedures are followed, you might be able to avoid a replacement or an unsightly gap.

• If the entire tooth has been knocked out, never touch the roots; this can cause a subsequent infection.
• Rinse away any foreign material such as dirt with warm water.
• Gently insert the tooth back into the socket and see a dentist as soon as possible.

“Baby teeth (primary teeth) are not implanted if they’re knocked out.”
