A dental product formed by a process and a method of using a denture including providing a denture having an outer face, applying a readily flowable material to the face. The flowable material comprises volatile material and polymeric material. Volatilizing at least a portion of the volatile material from the flowable material to form a readily peelable water swellable solid film. The film is substantially insoluble in water. The film comprising at least 10% by weight of the polymeric material. The denture having an outer face. The film adheres to the face and film effectively not being covalently bonded to the face. The product and method are preferably carried out using an adhesive dispenser including a container, a pump and flowable adhesive. The flowable adhesive is enclosed by the container. The pump is supported by the container and the pump is connected through a conduit to the flowable adhesive. A preferred flowable composition includes at least 1% volatile organic material, at least 10% by weight water, and at least 10% by weight polymeric material. The polymeric material comprising a compound within the scope of wherein m is an integer from 3 to 1,000 and each n independe…
