Scoop out a small amount of the putty and roll it into a ball, adjusting the size based on the number of teeth you are treating. Allow your body heat to soften the putty until it reaches a glue-like consistency. Apply the putty directly to the affected tooth or teeth, ensuring to dry off the tooth beforehand for better adhesion. For optimal results, it is recommended to apply the putty daily just before bedtime and then brush your teeth as usual in the morning.
