Answer: Cavity liners are used by dentists when fixing teeth. A cavity liner is used for several dental procedures including large cavities and root canals.
The liner is a 0.5 layer of very thin material. This is placed on top of the surface tooth being fixed. The liner is placed as part of the preparation of the procedure. It is essentially the foundation of the procedure.
The dental liner will help protect the tooth from fluids, any type of leakage, and harmful bacteria. The liners are easy to place and takes minutes to affix to the tooth.
