Sir, my TV viewing is limited. Tonight an ad particularly irritated me, bringing my previously subliminal thoughts about TV dental product advertising to the surface.

If companies wish to advertise their products – fine. If the format of the advertisement is such that a dental professional appears to be fronting it, I am far from sure that it reflects well on the profession. Evidence basis and financial bias are among the many issues involved. I have not noticed similar TV ads involving our medical colleagues.
