What is the purpose of lining in dental procedures?

The purpose of lining in dental procedures is primarily to protect the pulp from chemical irritation. When a tooth is prepared for restorative work, such as filling, the underlying dental pulp can be at risk from materials that may cause sensitivity or harm. A dental liner acts as a barrier, minimizing the potential for irritation from chemicals in the filling material, as well as from thermal changes that might arise from the dental procedure. This protective layer helps maintain the health of the pulp, ensuring a better outcome for the tooth in the long term.

Other aspects of dental lining, while important, do not primarily address the protective role against chemical irritation. Enhancing the appearance of teeth is typically not the main concern of a lining; rather, aesthetic improvements are usually achieved through the choice of restorative materials. Similarly, reducing the need for fillings or enhancing bonding strength speaks to other aspects of dental restorative techniques rather than the immediate protective function of lining materials.
