What Causes Black Teeth?
The first thing I think of that causes black teeth is the lack of brushing them. But, there are a few other reasons. It could be from medication or the lack of calcium in the body. When the body is has too much acid it will take from anywhere it can to make the PH balance normal and your teeth is made of calcium. Calcium is alkaline, so it will take the calcium from your teeth to balance out your PH. It could also be from bad habits from smoking, chewing, or even a bad diet.
