Professor Hawking cannot walk, stand, feed himself, speak, or write. He has amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease, hence you can hardly criticise the state of his teeth!

I am quite aware of that, which is why my comment asked why anyone doesn't brush his teeth, not why he doesn't brush his teeth. After all, his handlers dress him and wipe his butt, they can at least brush his teeth!

Well, I, and everyone I know in Britain brushes their teeth regularly, so you will have to ask his nurse/wife why she doesn't brush his teeth.

I am aware that there is a strange disapproval of British oral hygiene in the USA, but you're really scraping the barrel by trying to use this article as proof for that prejudice!
