What is the optimal way to transport an avulsed tooth?

Transporting an avulsed tooth properly is critical to increasing the chances of successful re-implantation. The optimal method is to place the tooth in a balanced salt solution or milk.

Balanced salt solutions preserve the vitality of the tooth's root cells, which is essential for the success of re-implantation. Milk, particularly whole milk, has a composition that can maintain the necessary pH and osmotic balance while preventing dehydration of the root surface. This environment helps keep the periodontal ligament cells alive longer, improving the chances of a successful reinsertion.

Other methods, such as using a paper towel, can lead to drying out the tooth and damage the periodontal ligament cells. Plastic bags do not provide an optimal medium for preservation, as they lack moisture and the necessary nutrients. Transporting the tooth on ice could lower the temperature to a point that could compromise the vitality of the tooth’s cells, making it a less suitable option.

In summary, the use of a balanced salt solution or milk is optimal for preserving the tooth's health during transport and ensuring the best chance for re-implantation success.
