The varnishes may optionally further incorporate therapeutic, antimicrobial and sensory enhancing ingredients such as fluoride, colouring or opaquing agents, and flavourings. In addition, the varnish may comprise a further natural or synthetic resin. The dental varnishes may be used in preventing tooth decay and/or alleviating tooth sensitivity. |
