Hello, try using hydrogen preoxide on your teeth..you can buy them at your local drugstore..
first, get a Q-tip and dab some of the hydrogen preoxide and then also dam them on your own teeth.. this helps kill bacteria and is also antiseptic. it also whitens your teeth faster. you could do this at least once a day, everyday and you can stop anytime.
WARNING: be cautious.DO NOT DRINK the hydrogen preoxide. it is for physical use only. and not to be eaten or drank.
you can also use cotton balls or you can just gurgle the hydrogen preoxide together with water. use 1 spoon of hydrogen preoxide and mix it on a glass of water and the you can gurgle.
Hope this helps! Bright Blessings!:D
