Smile with ease until you can afford dentures, bridges or implants. Quick and easy to follow Personal Fitting Instructions are provided on the package. Please note, these products are not a partial denture or a "Dental Device" and are intended for temporary use only. Flexible and Durable. If you have no lower teeth, the fitting material alone may not provide enough suction for the Instant Smile Teeth to stick to your gums. In this case, using a dental adhesive will help give you a better fit. Instant Smile Secure Adhesive is available.
