Generally speaking, most athletes will only wear a top mouthguard but this is a personal choice. It will be a mouthful to wear a guard on the top and bottom but for some sports, it may be necessary. Research shows us that the most likely teeth affected in an impact are the top front 4 teeth but there are many variables to consider – the type of sport you play, the probable impact you receive and the position of your teeth. For a person with their lower teeth sitting forward in a protruding jaw, it may be a preference that these teeth are covered as they are more likely to be the first point of impact. Different types of impacts require different methods in reducing the energy being transmitted to teeth. This is were NeoMorph shines – we developed NeoMorph as a mouthguard that will both absorb and disperse impact energy so we could protect for as many sport bases as possible.
