SafeTGard Has Provided Athlete's With Specialized Athletic Protection In The United States For Over 40 Years. SafeTGard was founded by Dr. A.G. Jacobs, a dentist, who out of concern for the high incidence of dental related sports injuries in his patients, invented the original "boil & bite" mouthguard for all impact sports. He then realized the many other special needs of the athlete, and began developing and manufacturing more types of athletic protective gear. SafeTGard's Made In USA products are also well accepted in the international marketplace for quality, price and prompt delivery.
