It is made from mineralized tooth particles, organic material, and sometimes bacteria pushed into the surface. It is most commonly discussed in fillings (bonding to enamel\/dentin) and root canal treatment (cleaning inside canals). Clinicians usually manage smear layer by modifying it, penetrating it, or removing it, depending on the procedure."}
