I went to the dentist a few weeks ago and got a goodie bag with a toothbrush and travel-size toothpaste. The message on the bag was a good use of marketing collateral.
A lot of personal care brands partner with industry professionals (see Sensodyne toothpaste commercials). However, having this text on the bag takes it a step further because it makes patients think that their real-life dentist personally recommends these brands. This is quite aggressive, since its likely that dentists receive products from competitor brands. But if dentists aren’t objecting, then why not? It pays to be bold.
