Teeth Night Guard is an American direct-to-consumer dental lab service operated by Sparkling White Smiles in Milwaukee, Wisconsin, specializing in custom-fitted oral appliances. Catering to individuals suffering from nighttime teeth grinding, clenching, and jaw soreness, the brand bypasses traditional dental office markups to offer direct-to-lab custom mouthpieces. Its core product catalog centers around custom dental appliances for light, moderate, or severe grinding—including soft flexible guards, hard acrylic guards, dual-laminated hybrid guards, and ultra-thin daytime bite guards. The brand also offers orthodontic replacement retainers, specialized cleaning disinfectants, and professional-grade whitening gels. Prices for custom guards range from $105 to $175, with accessories and whitening products starting around $16 to $45.

What sets the company apart in the direct-to-consumer dental space is its lab-direct model combined with professional-grade customization choices. Rather than selling generic boil-and-bite mouthpieces, the brand provides an at-home impression kit, allowing customers to take precise dental molds that are custom-crafted in a US dental laboratory using hygienic, BPA-free, latex-free, and phthalate-free materials. A key differentiator is its extensive material selection, enabling users to customize guard thickness (ranging from 1mm to 4mm) and rigidity (soft, hard, or dual-layer) to match their specific grinding severity and comfort preferences.

The online ordering process at Teeth Night Guard is supported by comprehensive customer service assurances and convenient domestic fulfillment. The company provides free standard shipping on all US orders, which includes a pre-addressed and prepaid return mailer to send completed impressions back to the lab. Customers are covered by a 30-day money-back guarantee starting upon receipt of the final guard, along with free adjustments or complete impression redos if the fit requires modification. Teeth Night Guard is a practical choice for adults seeking a durable, lab-fitted dental guard without the expense of an in-office dental visit. Shoppers preparing to place an initial order may want to look out for promotional site discounts or backup guard multi-pack savings before completing checkout.
