It would depend somewhat on the source of the water coming from the faucet.
But . . . one thing I have run into . . . if you use filtered water (even from a Brita) or bottled water, you will not be getting fluoride; so if you have bad teeth like I do, you might want to supplement fluoride intake somehow.
Hi auntjudyg, I have a question about flouride. I was under the impression that flouride actually has little-to-no effect on adult teeth. I'm wondering if you know of any research or articles that support your need for flouride? I'd love to read them
Thanks

Copper, when I was diagnosed with RA I was having a lot of dry eyes and mouth. My dentist gave me a prescription for flouride to rinse with daily because of my lack of saliva. He said saliva is what helps to clean the mouth.
When I told my hygienist I was using a filter, she asked me if it filtered out fluoride, an indication she feels that fluoride is very important for adult teeth. Now I mostly just drink it from the tap because I prefer that temperature, though.
I use a water filter, too. After researching them, I found what they filter out depends on the size of particles the filter material allows through. (That's why there's different filters for lead.)
Anyway, even if your filter does take out flouride, you should be ok if you brush twice daily - according to my dentist...
He feels that it's not so much a problem getting enough flouride (because we only need trace amounts), but more that people don't floss as well/often as they should, and the plaque doesn't allow the flouride to get to the teeth as well...
