That's what I do. Once to get rid of food debris. Then start with toothpaste. Then floss, rinse, and a quick brush again with toothpaste. But sadly too little too late with my teeth. They are screwed.
I rarely ate sweets as a child and avoid sugar. I rarely eat processed foods. Drink is another matter. I most likely have harmed my teeth from drinking beer/wine/smoothies and from being too rough when cleaning. I really miss my younger healthy teeth.
My teeth have felt horrible ever since they failed and were drilled and filled. And now bring me a lot of misery. Look after your teeth! Healthy teeth are incredibly attractive. IMHO.
