Strange shelf-fellows

Look closely at this photo I took recently at Walgreen's. Who decided where their inventory is stocked, and what was their motive? Dental hygiene products, including toothpaste, toothbrushes, floss and dentures, are located right next to the colossal rows of candy.

Have dentists quietly assumed control of Walgreen's to try to shame people out of eating candy? Is this a public service announcement by Walgreen's to remind you to clean off all of that sugar when you're done, or is it a diabolical attempt by the candy lobby to sabotage well-intentioned plans for good dental habits by seducing customers with their best treats?

The answer is likely none of the above, but this product placement still intrigued me. Ah, life and its mysteries.
