Twice a day. It certainly seems like a good idea. Use toothpaste. But not very much. Certainly you don’t need the huge long amount shown on tv and in pictures.
And shut the water off except when spitting in the sink or quickly rinsing your toothbrush. Anything more is wasting water. Think of all the energy and cleaning it takes to get that water to run through your tap. Don’t waste it.
Flossing is also a good idea. Though certainly, brush your teeth.
