Whenever placing or removing the Snapcaps, it is recommended to be leaning over a plugged sink with the upper teeth positioned over the lower lip. Snapcaps are intended for use only on the upper four front teeth and only work with metal braces. They are applied to the braces by simply positioning them over the front of the braces with the design facing outwards and then pushing toward the braces. They will literally snap into place over the outside of the braces.
To remove the Snapcap, slide it sideways until it is able to be lifted off the wire. They can then be placed back into their perforated container.
