Dental and Oral Tissue Trauma · CDA

If immediate re-implantation of an avulsed tooth is not possible, what is the recommended storage medium until reaching a dentist?

  1. Tap water inside a sealed plastic bag
  2. Cold milk, saline, or the patient's saliva
  3. Dry tissue wrapped gently around the whole tooth
  4. Gauze that has been soaked thoroughly in alcohol
Show answer and explanation

Correct answer: Cold milk, saline, or the patient's saliva

If reimplantation isn’t possible, storing the tooth in cold milk, saline, or saliva (or a specialized tooth-preservation medium) helps keep the periodontal ligament cells viable until dental treatment.
