First, let’s answer this question: What causes cavities? The
answer in the simplest terms is acids.
The longer explanation is this.
Bacteria adhere to your teeth (plaque).
The bacteria then use the sugar you consume and create acids. The acids eat away at your teeth and form
holes. The cycle continues as the
bacteria bore their way deeper and deeper into the teeth.
What is the main thing the bacteria need to thrive? Sugar.
So are diet drinks also bad for teeth? Most diet drinks do not contain sugar. They use some form or another of artificial
sweetener. The good news is that
cavity-causing bacteria cannot metabolize these sweeteners to form acids. The bad news is, just like their “regular”
counterparts, diet drinks are extremely acidic in themselves. Again, what causes cavities? Acids!
And so, even though the typical path of cavity formation (bacteria eats
sugar, releases acids, forms holes in teeth) is not followed as much, these
drinks can just bypass the bacteria step and eat away at your teeth on their
own. Pathologically speaking, it is a
different type of cavity with different attributes than that of a bacteria
caused one. However, in the big
picture, it doesn’t really matter. In
both situations, tooth structure is eaten away and once it’s gone, it’s gone.
Drink more water.
There is nothing better!
Limit soft drinks, including diet soft drinks, to meal
times.
At the very least, swish around with some water after
consuming to remove some of it off your teeth.
