Walmart offers a variety of mouthpieces designed to reduce snoring including The Doctor’s Advanced Comfort Night Guard, Brain Pad LPP-02 Blue Mouth Guard and DenTek Comfort Fit Dental Guard, according to the company’s website. As of 2015, all mouthpieces have a three-star or higher Walmart customer rating.
The mouthpieces help keep the air passage open by adjusting the position of the jaw, tongue and soft palate, according to the Mayo Clinic. They are useful in treating snoring caused by obstructive sleep apnea. Aside from mouthpieces, Walmart also sells a variety of other anti-snoring products. These include chin straps, nose clips, sprays and tablets.
