What should you do after rinsing a knocked-out tooth?

Storing a knocked-out tooth in milk is the recommended course of action because it helps to preserve the tooth's vitality until dental treatment can be sought. Milk provides a suitable environment due to its balanced pH and nutrients, which can keep the root cells of the tooth healthy and increase the likelihood of re-implantation success.

Once a tooth has been knocked out, it's crucial not to allow it to dry out, which would occur if the tooth was thrown away or if any attempt was made to dry it off. Keeping the tooth moist greatly enhances the chances of successful reinsertion by a dental professional. Placing the tooth back in its socket is also not advisable if it can’t be done immediately and properly, as this could cause further damage. Thus, milk serves as an effective storage medium until the individual can receive appropriate dental care.
