As someone who suffers from nocturnal bruxism (teeth grinding), I have used dental night guards for more than two decades. Over the years, I have alternated between custom-fitted guards provided by dentists and orthodontists and a wide variety of over-the-counter products.
Because I have tried nearly every over-the-counter night guard available, I was interested when I came across the DenTek Ultimate Dental Guard. At the time, it was a relatively new product with excellent reviews. A friend had recommended it to me and described it as the most comfortable night guard she had ever used. Its smaller, less bulky design was particularly appealing.
I will begin by saying that this was one of the most comfortable dental guards I have ever worn. Unfortunately, my experience took an unexpected turn.
After wearing the guard for two nights, I woke in the morning with profound hearing loss in my left ear. I had no pain, dizziness, fever, or other symptoms. Initially, I did not suspect the dental guard as the cause and continued using it for approximately three more weeks.
During that period, the hearing loss persisted and a sensation of a block ear or eustation tube eventually developed. I underwent treatment with two courses of antibiotics without significant improvement. Eventually, I decided to discontinue the DenTek guard and returned to a more conventional upper dental guard that covered the entire upper arch. To my surprise, after a single night of wearing the conventional guard, I noticed improvement in my hearing. Over several days, my hearing completely recovered.
My Theory
What follows is my personal hypothesis regarding what may have occurred. It should not be interpreted as proven fact. As an osteopathic physician, I received extensive training in cranial anatomy and osteopathic cranial concepts. Within osteopathic medicine, the skull is viewed as a dynamic structure with subtle motion occurring between all of the cranial bones and fascial planes. (Fascia is a connective tissue network that is present in the entire body and connects organs, bones, and muscles.)
The DenTek Ultimate Dental Guard utilizes two posterior bite pads connected by a bridge that spans across the roof of the mouth but does not actually contact the palate. This differs from a traditional full-coverage night guard, which generally has no suspended structure crossing the palate. It also differs from a retainer-style appliance, which may cover the palate but is custom molded to conform closely to an individual's anatomy rather than hanging below it. As a result, the DenTek design occupies space beneath and away from the palate in a way that is distinct from both conventional full-coverage guards and retainer-style appliances.
Under normal circumstances, the tongue rests suctioned up against the palate. My concern is that the suspended bridge of this appliance interferes with the tongue's natural resting position. As the tongue attempts to elevate and contact the palate during sleep, it exerts pressure against the bridge connecting the two posterior bite pads.
My hypothesis is that when clenching or grinding occurs simultaneously with this upward tongue pressure, forces may be transmitted through the appliance in a manner that differs from traditional night guards. Specifically, the two posterior bite pads may be pulled toward one another, potentially creating inward forces on the molars and the inferior (lower) portions of the maxilla or upper jaw bones. When the inferior maxilla is pulled inward, the superior (upper) maxilla flares outward.
Because the maxilla articulates with the zygomatic bones, I believe these altered force patterns may also affect the position and mechanics of the zygomatic complex and from there the temporal and spenoid bones as well as all the fascia (connective tissue) in the head. This movement could potentially influence nearby structures associated with the sensitive middle ear anatomy, the eustachian tube, or surrounding tissues. While this remains a theoretical explanation, it is the mechanism that I believe best explains my personal experience. Again, this is a theoretical explanation and one that has not, to my knowledge, been formally studied.
Final Thoughts
My experience with the DenTek Ultimate Dental Guard was unusual and may not be representative of other users' experiences.
However, because of the timing of my symptoms, the lack of response to medical treatment, and the subsequent improvement after discontinuing the appliance, I felt it was important to share my experience.
This product review is intended to describe my personal experience and observations and should not be interpreted as medical advice or proof of causation.
