Remove cap from pen. Click the base of the pen to deliver a small amount of the whitening gel to the brush tip. Apply a thin layer of the gel directly to the front of the teeth. Replace cap. Use twice daily for the best and brightest results. Each pen contains approximately 30 applications. For best results do not rinse, eat or drink for 20 minutes after use to allow the whitening agent time to work.
