More than that,

And more than that:
Cavities are primarily caused by bad dental habits, including diets high in sugar and acids, use of tobacco products, and poor oral hygiene. However, people who take excellent care of their teeth also get cavities—sometimes even more than those without a good oral care routine. If you get cavities more easily than others, genetics may partially be to blame.

Agree...lots of people simply have ‘bad teeth’. In my case, though, I started with good teeth, didn’t bother with them, and they got bad. So I did the floss/cleaning/brushing routine and they’re back to good.

But if I started with bad teeth, then it’s (obviously) still best to keep them as clean as possible and deal with the issues as they arise.
