Do you know why there is tooth decay?

There is often a layer of dental plaque on the surfaces of our teeth, which is filled with bacteria.

When we eat, the bacteria in dental plaque will break down the sugar of the food and produce acid.

Food + bacteria = acid

The acid attacks our tooth surfaces and leads to tooth decay.
Every time we eat or drink, there will be a chance for developing tooth decay.
