A blower for dental use, which comprises a support structure (1), an air source and a handpiece (28). Said handpiece is connected to a pipe (14) supplying air to be blown in, which is produced by the air source, and a blowing nozzle (13) for the air received from the supply pipe (14). The blower 10 also comprises means (12) for heating the air to be blown in, which means are mounted within the handpiece (28) so as to heat the air received from the supply pipe (14) and release it, heated, to the blowing nozzle (13). The air source comprises a compressor (11) which is housed inside the support structure (1) and is connected to the handpiece (28) by means of the air supply pipe (14) and produces a constant air flow having a pressure when leaving the blowing nozzle (13) of between 0.1 and 1 bar. The blowing nozzle (13) has a maximum outer dimension ranging between 0.4 and 1.3 mm and is able to be inserted inside endodontic canals so as to inject the air expelled from it into endodontic canals, once inserted therein.
