Apollo Sentinel Mouthguard — Boil-and-Bite Mouthguard

Choosing the protective

Built for athletes who put in hard rounds, Sentinel covers boxing, MMA, and Muay Thai work without getting in the way. It excels in sparring, partner drills, and high-output pad or bag sessions where consistent protection and easy breathing matter. The light, compact profile reduces distraction over long classes and conditioning blocks. For a straightforward guard that keeps focus on timing and defense rather than bulk in the mouth, this is the dependable choice.

One size fits athletes 13 and up. The cut runs compact due to the approximate 6.5 cm length, suiting smaller to average jaws or anyone who prefers less material. Larger jaws seeking maximum rear molar coverage may find it shorter at the back. Not designed for braces. For athletes under 13 or with orthodontics, use a youth or braces-specific guard. Expect a snug, low-bulk feel that stays out of the way between rounds.

EVA construction handles impact buffering without excess bulk. At about 28 g, it stays light, and the roughly 6.5 cm length keeps the footprint compact for long sessions. The streamlined build focuses on consistent protection and comfort rather than gimmicks, delivering a stable bite platform during sparring and drilling. Simple, proven materials make it easy to wear round after round without weighing down the jaw or crowding the airway.

Rinse after training, air-dry fully, and avoid hot water or car dashboards that can warp EVA. Clean periodically with mild soap, then store dry in a ventilated case. Inspect for tears, deep bite marks, or compression set, and replace when structure is compromised. Within Apollo mouthguards, Sentinel is the low-bulk, daily trainer for sparring-heavy weeks; athletes who need youth sizing or orthodontic compatibility should choose a purpose-built alternative.
