There are two methods to use activated charcoal to whiten the teeth. Consult your dentist before applying any method. Please do not take the matter of your dental health lightly, it could lead to bigger problems in the future. Method 1: Use a toothpaste in which activated charcoal is already added in it to see if it works for your mouth and teeth. Dentists usually recommend this to people with sensitive gums and teeth. It will be less abrasive. However, it is less effective in whitening your teeth, it will remove the stains though. If you are a smoker or drink regularly, you will notice your teeth getting whiter and smokers and coffee or wine drinkers have paler teeth than people who do not use these things. Method 2: Another way to use activated charcoal is to make your own charcoal paste. It is recommended for people with healthy gums and teeth as you will be applying charcoal directly on the teeth, not mixed with any other paste. Chemicals or ingredients that companies include in their product to make it more effective will not be included in your product, which might make it less useful as it might not whiten the teeth. Follow the following steps to make your own activated charcoal paste at home: 1. Buy some tablets of activated best charcoal teeth whitener and fully crush one in a bowl. 2. Fill one teaspoon with water and pour it into the bowl and mix it. You can add more water drops, just don’t make it drippy, it won’t work otherwise. 3. Take a soft-bristled toothbrush, put the paste on it and try your homemade charcoal paste!
