This response is ridiculous. You cannot possibly believe that it's that difficult to get barely educated (or even the smart) hygenists and/or busy dentists to understand and buy this product? It's a two pronged strategic sell focusing in on either health benefits or profitability, contingent on the practice culture. That's why people work from 10-2pm, because it's easy. Let's go gentle on the term "seller", this is such a slight step above a pharma job that saying it's true sales would be lying.
There was no intent to make people feel bad. Anyone who is at OP that has a brain in their head is making this job work for their benefit with respect to finances, time management and benefits. We just have to put up with dummies like you who aren't able to think your way out of a wet paper bag.
