Pure water. You can try some of the concentrated liquid water enhancers without sugar. Avoid sugar.
As far as teeth..that's a whole other matter younger people don't take care of teeth and as a result older people spend 10's of thousands on their teeth later in life.
I use a waterpic, sonacare toothbrush and floss daily. Cheap compared to caps.
As mentioned rinse. Get your teeth cleaned twice per year. I used to have a number of "4-pockets". I no longer have any 4's. Taking care of teeth is the best investment in you that you can make.
