Jenning gag
Definition
A Jenning gag is a metal spreader gag that originally comes from the medical world and is used to keep the mouth open. Within BDSM, this tool is sometimes used to force the sub to keep their mouth open during oral play or as part of dental play, control, and humiliation play.
Explanation of the Jenning gag
The Jenning gag was developed for dental or surgical purposes and consists of two curved metal parts that are twisted apart using a screw mechanism. This forces the mouth open and prevents it from closing. In BDSM, the Jenning gag is used in the context of oral submission, medical fetishism, or obedience training.
The visual and physical intensity of this tool makes it popular with players who enjoy a strict, medical, or clinical scenario. Because the mouth area is extremely sensitive, the use of a Jenning gag is often experienced as very intense—especially when the sub has to remain in this position for a long time.
Safety & points of attention
Only use the Jenning gag with partners who are fully aware of the risks and who have experience with this type of device. The mouth, jaw muscles, and lips can quickly become overloaded.
Make sure that the sub can still breathe, especially when used in combination with other forms of bondage or during oral sex.
Check regularly to ensure that saliva does not accumulate, causing the sub to choke.
Do not use excessive force when opening the device – the jaw may dislocate or the lips may tear.
Disinfect the device thoroughly before and after use, as it comes into contact with mucous membranes. For beginners, it is preferable to use a plastic or rubber version with rounded edges.
