I can understand that you might have gotten excited by the word “instinct” on the package. Maybe you became just a little enraged by the plastic’s resistance.
I can also understand that you may have overlooked the “cut here” mark.
However, your dentist and I agree, you should not open things with your teeth, unless you are missing a thumb.
If you are missing a thumb, you can open things in whatever way that works and/or gives you joy.
That’s also the dogs’ point of view on the subject… and hey!! Thanks for feeding them!!

You’ll be telling me next that eating various forms of boiled sugar is also bad for my teeth.

Well… boiling the sugar has to be better than tearing the bag open and sticking your head in to snack…
