You want to keep your teeth as long as possible. That’s why you brush and floss daily.
Even so, you probably are not brushing and flossing perfectly every time. That’s not a criticism. It’s just a recognition of reality.
That’s also why you should come in for professional dental cleanings a few times each year. We remove plaque, tartar, and harmful bacteria. Plus, you can add a layer of protection to your teeth with dental sealants and fluoride treatments while you are here.
