A plastic temporary dental crown is a short-term restoration used to cover and protect a tooth or dental implant while a permanent crown is being fabricated. It helps preserve tooth position, gum shape, and bite alignment during the healing or laboratory phase.

Temporary crowns also provide basic chewing function and improve appearance, preventing sensitivity and discomfort. Although not intended for long-term use, they play an important role in protecting oral tissues and ensuring a smooth transition to the final restoration.
