Why Your Teeth Feel Fuzzy by Bedtime

Run your tongue over your teeth right before bed. Feel that fuzzy, slightly rough layer? That's not dirt. That's biofilm, and it's forming on your teeth all day long.

It's completely normal. What matters is what you do about it.

Biofilm is a thin layer of bacteria that starts forming on your teeth within minutes after brushing. Throughout the day, as you eat and drink, that layer thickens. By nighttime, it's dense enough to feel. Left alone, it hardens into plaque, and eventually tartar, which only a dentist can remove.

This is exactly why brushing twice a day matters so much, not once. 

That fuzzy feeling isn't something to worry about. It's actually a helpful reminder your body gives you. It's your mouth telling you exactly when it's time to clean. Listen to it, and your teeth stay one step ahead, every single day.
