Permanently misaligned jaw.I have used the zyppah snoring appliance for several years.I have recently been diagnosed (by both prosthodontist and orthodontist) with a serious misalignment of jaw caused by extended use of this device.Both upper and lower teeth have shifted and jaw has move forward.It now requires extensive orthodontia to fix to prevent even more extensive damage to my teeth long term due to misaligned bite.Hcps report that this is a known issue with this product and others like it, yet there are no safety warnings to prevent other consumers form being similarly harmed.Fda safety report id # (b)(4).
