What Is an Open-Mouth Gag?

An open-mouth gag is a BDSM gag designed to keep the wearer's mouth held open, preventing them from closing their jaw. Unlike a ball gag which fills the mouth cavity, open-mouth gags use bars, rings, spreaders, or shaped inserts to hold the jaw apart — creating access for oral play, deep-throat practice, or simply the visual of helpless exposure. The open-mouth position triggers increased salivation (drooling), which adds to the submissive aesthetic and reinforces the power dynamic.

Types of Open-Mouth Gags

Deep-Throat / Studded Open-Mouth Gags use a shaped bar or panel that holds the mouth open at a fixed width, often with a textured or studded surface for added sensation. Tongue Spreader Gags depress the tongue while holding the mouth open, creating access for oral scenes and adding a medical-play aesthetic. Metal Ring Tongue Depressors — combines a ring gag with a tongue depressor bar, giving the dominant both mouth access and tongue control. Butterfly Ring Gags feature a split ring design that holds the lips open while allowing more natural jaw movement than a solid O-ring. Silicone Lips Gags use a molded lip-shaped panel that mimics an open mouth — highly visual and perfect for roleplay and photoshoot scenes.

How to Choose an Open-Mouth Gag

Jaw width is the key factor — the gag should hold the mouth comfortably open without straining the jaw joint. Start with a narrower width (2-3cm) and work up to wider designs. Material: silicone open-mouth gags are the most comfortable for longer wear; PU leather and metal designs are more intense and visually striking but require more careful fit. Purpose: choose a deep-throat gag for oral scenes, a tongue spreader for medical play, or a butterfly ring for general open-mouth access. Beginner tip: start with a silicone lips or butterfly ring gag — they're more forgiving on the jaw than fixed-width spreaders.

Safety Tips for Open-Mouth Gags

Open-mouth gags put more strain on the jaw than ball gags — start with short sessions (5-10 minutes) and increase gradually. Check for jaw fatigue, clicking, or pain and stop immediately if the wearer feels any. The drooling is normal — keep a towel or bib handy. Establish a safety signal before gagging. Never leave a gagged person alone. After use, clean silicone and metal parts with warm soapy water or toy cleaner; wipe leather straps with a damp cloth and air dry completely.
