My mom grew up in a small South American country. They used bristly-edged plants kinda like toothbrushes. No toothpaste. My mother & her siblings all have very good teeth – never a cavity, never even a bit of discoloration.
That’s cuz good teeth are selected for through evolution. If you didn’t have good teeth, you died young from tooth infections. It was a common cause of death in the past, and continues to be in some parts of the world.
Modern toothpaste is relatively new but rudimentary abrasive tooth powders have been around for millennia.
Toothpaste isn’t nearly as important to oral health as simply brushing your teeth in the first place, even with plain water or a herbal mixture. Toothbrushes have also been around for thousands of years.
I had an interesting chat with my dental hygentist about that.
She explaines that by FAR – the most important aspect is the brushing. Toothpaste is a “nice to have” – but you can maintain your teeth and gums without it as long as you brush well.
Side note: That question prompted the dental office to put “Brushing instruction – $20” on my bill. I’m still pissed off about that.
I think the most simple answer really depends on the culture. There are so many alternatives to toothpaste that do not require any production or technology.
I believe one of the most common ones is charcoal, when used properly it will have the same effect as any toothpaste. I have also heard about coconut oil, some types of clay and even salt. Some cultures even use plant fibres as brushes and floss! I am also pretty sure that before toothpaste became standard, most 1st world countries were using baking soda – very cheap and effective.
