P's & Q's are made of the same FDA compliant material as all Chewy Tubes and offer a safe, non-toxic durable surface for biting and chewing activities. They are latex-free and do not contain PVC or phthalates. P's and Q's are solid rather than tubular so they offer a firmer surface for biting than the red or yellow Chewy Tubes. Young patients enjoy grasping the P with their newly developing fine motor skills.

The bitable stem of the P reaches back into the molar region sending appropriate proprioceptive input into the TMJ as the patient practices biting. Babies enjoy the Q extension for tongue exploration. For larger jaws, the larger Q offers a firm bilateral surface for jaw closure activities.
