MASK MOUTH- this is literally a real thing. Wearing a mask can lead to serious issues like gum disease, tooth decay, cavities etc. There is even an entire section on Colgate's website about it. Next time someone is preaching their love of masks, tell them do do a simple search on it.

Also, has anyone found any evidence that increased carbon dioxide intake can lead to loss of smell and taste?
