Using Kryolan Tooth Enamel is easy. First, make sure your teeth are dry. This helps the enamel stick better. Then, take the brush and apply the enamel gently on your teeth. Wait for it to dry before closing your mouth so it doesn't smudge. To keep your teeth healthy, don't leave the enamel on for too long. When you want to remove it, you can either brush your teeth really well or use a bit of alcohol. Remember to store the enamel in a cool, dry place to keep it in good condition.
