The main ingredient in tooth whiteners is hydrogen peroxide, which is very inexpensive.
Just rub your teeth with the peroxide (using a q-tip), wait 30 seconds and then brush.
You also can swish your mouth with half water and half peroxide for 30 seconds. Then brush.
When brushing your teeth, you don’t need to put toothpaste across all of the bristles. Just put a dot of toothpaste on your brush the size of a small pea.
If the bristles of your toothbrush get frayed and worn quickly you are probably brushing way too hard. Scrubbing your teeth really hard is not good for them and can damage your gums so take it easy and brush gently.
