For the last couple of months I’ve noticed some white splotches on my pillow in the morning. It’s obviously from drooling while I sleep, but what is it? At first I theorized it was left over residue from toothpaste. But I did an experiment and for a week I did not use toothpaste before I went to bed (rinsed and flossed, but no toothpaste. I did brush in the morning and afternoon, however).
Splotches continued. I would think that if I drool while I sleep these calcium like splotches would have always been on my pillows my entire life. But this just started about 3 months ago. So WTF?
