Something to think about is what advantage people will get to pay you with Bitcoin? If none, then why someone would use is coins to pay a dentist, knowing people prefer to hold their bitcoins and wait to see the price increase, etc. People are only interested in money

If I get a 10% discount if I pay with Bitcoin I may think about it but other than that why should I pay with BTC. I could simply convert BTC to fiat and pay you with.
Also, did you consider that most people have health insurance? Let's say someone pays you in BTC and then the insurance refund in fiat? where is the interest for the patients?
