Protect teeth from damage caused by nighttime teeth grinding with the new SleepRight ProRx Custom Dental Guard. It protects ten times longer than the leading competitor, based on a lab study. The durable core is an expansion upon the current bite pad technology used in the SleepRight No-Boil Dura-Comfort Dental Guard. One can now expect to get the benefit of a much longer lasting dental guard in a custom, form fitting guard.
