Filmogenic compositions are described for topical anaesthetic bioadhesives (TABs) comprising a) a xanthan biopolymer matrix selected from Xanthomonas species and pathovars, including Xanthomonas campestris pathovars campestris and maninhotis, and Xanthomonas arboricola pathovar pruni, a producer of pruni xanthan, wherein the matrix is made of pure or combined xanthan varieties in any proportion, said matrix comprising between 1% and 95% by weight of the total weight of the composition, and additives or excipients； b) at least one anaesthetic, in a proportion of 0.1% to 50% by weight of the total weight of the composition. The topical anaesthetic bioadhesives (TABs) are also described, and they may be applied to the gingival mucosa and/or alveolar mucosa on the buccal (1) or lingual/buccal (2) surfaces with extensions and anatomical contours for crowns of the upper and lower dental arches.
