I drink tap water too. My dentist told us that there is flouride in tap water that can be beneficial for your teeth and since I can't do flouride treatments (it nauseates me) I get by with the tap. I don't think it's caused any issues but I guess it depends on where you live and the quality of water. I do have a filter on my fridge water that my kids and hubby prefer but it's sort of "tasteless" and too cold for my tastes.
Your dentist should do the research on fluoride. It only helps your teeth when applied to the outside not ingested, the original claim has been proven false about
ingesting it. It is a known poison, Look on the back of any fluoride toothpaste it will say "If more than what is used for brushing teeth is swallowed contact poison control center".
Here is a link to a news clip of a Tenn. doctor and lawmaker trying to ban it in his state.
