Question

Which of the following should be done if a tooth is avulsed?

A) Clean with hydrogen peroxide
B) Place it in milk or saline
C) Brush it thoroughly
D) Leave it dry

Answer 1

For an avulsed tooth, it should be placed in milk or saline to preserve it, not cleaned with peroxide, brushed, or left dry, and immediate dental care is necessary.

Step-by-step explanation:

If a tooth is avulsed, which means that it has been completely knocked out of its socket, the best immediate action to take is to place it in milk or saline solution. It's important not to clean the tooth with hydrogen peroxide, brush it thoroughly, or leave it dry as these actions can damage the delicate cells on the root surface that are necessary for successful re-implantation.

Preserving the tooth in a moist medium like milk or saline helps maintain the vitality of the root's periodontal ligament cells, giving the best chance for the tooth to be re-implanted by a dental professional. Remember to seek dental care immediately after the incident.
