Maybe in your country. Here in France AirBnB are both cheaper and the rooms are nicer than hotel. Some of them could be landlords and profit… but some others rent something that would not be fitting as a location (like a vacation flat or a subpart of a house) but is OK for staying just a couple of days.
So I disagree heavily with your generalisation
At least you are going to the dentist. My uncle was not brushing his teeth. And never to the dentist. Eventually they had to remove all of his teeth because it was all infected and it was too unbearable for him.
I had a depression period of my life where I was doing the worst possible treatment to my teeth - was eating a lot of sugar and would skip brushing here and there; also I was not brushing effectively. My teeth are not in very good condition right now. I wish I had kept a good mouth hygiene even when I was depressed.
