A dental curing light sleeve with a closed distal end, an open proximal end, and an elongated tubular structure with at least three different sections of varying circumferences is disclosed. The sleeve may be created by heat sealing at least two sheets of an impermeable polymeric material. Three sheets of impermeable polymeric material may be used to create the sleeve, with the two outer sheets being substantially the same length and dimensions and the third sheet of a shorter length placed between the two outer sheets. This provides the sleeve with added strength along the majority of the sleeve while still having minimal obstruction of the curing light, which may occur when additional sheets of material are included. Additionally, the sleeve may have a ring section located at the open proximal end, which allows a user to grip the sleeve and apply it to the dental curing light.
