The Open Wide Mouth Rest is helpful for those who won't cooperate or who lack motor control to keep the mouth open. It is made from special foam with a rigid core to add stability. It is sturdy enough to resist biting pressure, but has enough “give” to be comfortable for the person receiving care. The Open Wide mouth rest (OWD) has a long handle for safe, easy control. The "thick" version (OWDT) has 40% more foam for those with more aggressive biting pressure.
Ask your dentist, hygienist or medical professional to demonstrate proper use of the mouth rest.
