"Are we saying then, that if say from day dot you were born, your teeth come in and you avoided the processed carbs and the sugar, you're actually very unlikely to get tooth decay?"

You will definitely not get tooth decay! 100% certain. You can obviously have gum disease but not tooth decay. Tooth decay is purely 100% down to diet.

It goes to a brown stain, then it turns into a little cavity, and then it turns into a bigger cavity.

Now, if we get to this brown stage, we can reverse it. We reverse it by stopping the sugar and the carbohydrates, we start having more water, we start cleaning better and you can actually reverse the cavity and your body can heal itself.
