These are 10 mouth gags used in bondage.
1. Ball gag
is usually made of rubber or silicone in the shape of a sphere with a strap passing through its diameter. In use, the ball is strapped into the mouth behind the teeth, with the straps going around the head to secure it in place.
2. Bit gag
is styled like the bit used in a bridle for a horse, and much of its sexual appeal stems from fetishistic symbolism in pony play.
It consists of a bar that is held in place in the wearer's mouth by straps or other device. Unlike the metal bit that is most common in horse bridles, the bar of a bit gag is usually a soft rubber cylinder. It is not very effective in preventing speech, unless combined with mouth stuffing. Because of the possibility of injury to the lips, the bit gag is not suitable for rough play.
3. Butterfly gag
is a wing-shaped gag, that is usually inflatable by means of a rubber bulb. The central part fits behind the teeth to fill up the mouth, while the wings go between the teeth and the lips. The gag inflates in the shape of a butterfly. This kind of gag is very hard to keep in the wearer.
4. Cleave gag
is scarf or cloth which is pulled between his or her teeth. Sometimes, a knot is tied in the centre of the gag so it works more like a ball gag.
While such a gag of thin material is not very effective, a thick scarf can be used to hold his or her mouth open, and the tighter that gag is tied the better it works, although no matter how tightly it is tied, the gagged person can usually spit it out.
5. Over-The-Mouth (OTM) gag
is often described in fiction as preventing the subject from speaking through the use of soft materials such as scarves or bandannas. In practice it does not silence the subject very effectively. The long scarf or bandanna is pulled over the subject's mouth and tied at the back of his/her head. It is also sometimes called the "detective gag" because many of its first appearances were in crime serials.
6. Wiffle gag
is a simple ball gag that replaces the standard solid rubber ball with a light plastic ball similar to the one used for the game of floorball. It is generally safer because there is constant airflow.
7. Bandit gag
is also known as an over-the-nose or mouth gag. It covers the mouth as well as the nose, and is commonly used in Japan bondage. Without stuffing it is not very effective.
8. Forniphilic gag
is a type of gag that has the primary purpose of objectifying or humiliating the wearer. The gag becomes a mounting point for a tool or other device which allows a slave to perform a task or service for their master or mistress.
When employing the gag, the slave's hands are usually bound behind them so they have no other option than to control the tool with the gag.
9. Funnel gag
consists of a funnel with a tube leading from its spout into the mouth, usually with straps to hold the tube in. Such a gag is used to force the bound person to drink a fluid. It is very easy to choke during such forced drinking.
10. Whitehead gag
is a device used to hold the patient's mouth open in dental surgeries. However, it is used in sexual fetish or bondage play.
