Many. There wasn't fluoride in the water where I grew up for the first decade of my life. Tips:

Bring earbuds and clear it with the dentist that they'll tap your arm if they need to talk to you. Have a playlist ready. If you can afford it / have the right insurance, ask for gas to help you zone out. If you feel pain, they didn't give you enough novocaine. My dentist informed me that people with red hair are less sensitive to the drug and need more of it (she noticed my beard comes in kinda reddish when she told me about that). Don't be afraid to let them know of discomfort; they want you to be ok during the procedure so not to make you avoid getting treatment right away in the future, thus making whatever problem worse.

You can maybe ask for a single pill script for a downer like zanex if you don't drive to the appt.
