You think humans are the only species that practice dental hygiene? Think again. Nina and Nana have something to say that might embarrass you in to flossing everyday.

To be honest, I hadn't heard about flossing, until I was about 21. Someone in graduate school mentioned it, and I had no clue what they were talking about. Eventually, a friend enlightened me about the importance of flossing.

In the words of Dr. Pooja Jagtiaani, a dentist running her own successful practice for a decade:

Once a child's teeth start to fit closely together, usually between the ages of two and six, parents should start to get their children in the habit of flossing daily. As they develop dexterity, you can help them learn to floss. Children usually develop the ability to floss on their own around the age of 10.

But dentists aren't the only people who harp on the the importance of dental health. What really drives the point home, is that Dr. Suess does too. In fact, he wrote a rather entertaining book about it, cleverly titled The Tooth Book, where he gives you some very helpful tips, like, it's probably not a good idea to bite your dentist. Now who'd have thunk it? But seriously, it's a pretty awesome book.

Now, as much as we humans like to pride ourselves on hygiene and sophistication, we aren't the only species that flosses. Baboons do it too. Ouch! Now that's going to sting those of us who don't floss. Even baboons manage!

And they don't bother with buying floss string or picks. They just use each other's hair, or broom bristles, or really anything that's lying around. Resourceful, aren't they?

So what's Nina up to now? Let's find out how she is going to horrify Nana this time.
