Open Mouth Gag Guide: Types, Tips, and Safety
So you are curious about open mouth gags. Good. They are one of the more interesting tools in BDSM play, and once you understand how they work, they are pretty simple to figure out. This guide covers everything: what they are, the different types, how to use one safely, and what to watch out for. No judgment, no lecture. Just the stuff you actually need to know.
What is an open mouth gag?
An open mouth gag is a BDSM toy that holds the mouth open during play.
Unlike a ball gag, which fills the mouth and restricts speech, an open mouth gag keeps the mouth open without blocking it. That is the key difference. The mouth stays accessible.
They are used in power exchange scenarios, sensory play, and oral play setups. The person wearing one has limited control over their mouth, which is exactly the point for a lot of people who enjoy that dynamic.
Most open mouth gags fit behind the teeth and are held in place with an adjustable strap around the head. They come in lots of styles and materials, which we will get into below.
What are the different types of open mouth gags?
There are several styles, and each one feels and works a little differently.
O-Ring Gag
The O-ring gag is the most common type. It uses a circular ring that sits between the teeth and holds the mouth open in a round shape.
They come in different ring sizes, usually measured in diameter. A smaller ring is more comfortable for beginners. A larger ring creates a more open position and a more intense feeling.
O-ring gags are usually made from metal or hard plastic. Metal ones are more durable but harder on the teeth. Silicone-coated rings are softer and easier on the jaw.
Spider Gag
The spider gag is a variation of the O-ring design. Instead of a plain ring, it has small spokes or hooks extending inward from the ring.
Those extra arms help keep the gag in place even better. It also gives a more dramatic look, which many people enjoy for the visual aspect of BDSM play.
Spider gags are popular with people who want something that stays put during active sessions.
Jennings Gag
The Jennings gag looks like a medical tool, because it originally was one. It uses a ratchet mechanism to hold the mouth open at a specific width.
This style gives the person using it precise control over how wide the mouth is held open. It is adjustable on the fly, which makes it a favorite for more advanced play.
Dental Gag
A dental gag uses padded bite plates or cheek retractors to hold the mouth open. It is often used in roleplay scenarios involving a medical or clinical theme.
These are usually more comfortable for long wear because the pressure is spread across the teeth more evenly.
PU Leather Strap Gags
PU leather gags wrap around the head with a soft adjustable strap. They tend to be gentler on the skin than hard plastic or metal options.
They come in colors like black and red and often include metal rings or buckles for extra style. Good choice if you want something that looks great and feels comfortable during extended wear.
What materials are open mouth gags made from?
Material matters more than most people realize when it comes to comfort and safety.
Here is a quick breakdown of what you will see most often:
- Silicone: Soft, body-safe, and easy to clean. Great for beginners. The most comfortable option for the mouth and teeth.
- Stainless steel: Durable and easy to sterilize. Heavier and harder on the teeth. More intense feeling.
- Hard plastic or acrylic: Lightweight and inexpensive. Less comfortable than silicone but holds its shape well.
- PU leather: Used for the strap and frame rather than the part that goes in the mouth. Soft on skin, adjustable, and available in lots of styles.
- Rubber or latex: Flexible and affordable but porous. Harder to clean thoroughly. Not the best choice if you have a latex allergy.
Pro tip: If you are buying your first open mouth gag, go with silicone or a silicone-coated ring. It is much kinder on your jaw and teeth during longer sessions.
How do you use an open mouth gag safely?
Safety is the first thing to sort out before you start. These are the steps to follow every single time.
- Talk first: Discuss what you both want from the session before anyone puts anything on. Agree on what is and is not okay.
- Set a safe signal: Since talking is restricted when wearing a gag, agree on a hand signal or object to drop as a stop signal before you begin.
- Fit it properly: The gag should sit comfortably behind the teeth. It should feel secure but not painfully tight. Adjust the strap so it is snug, not digging into skin.
- Start with short sessions: For your first few times, keep wear time to 10 or 15 minutes. Build up gradually from there.
- Watch for drooling: It happens. Keep a towel nearby and make sure the person wearing the gag can breathe clearly through their nose the whole time.
- Check in regularly: Use your agreed hand signal or check in verbally using yes or no signals every few minutes.
- Remove carefully: Loosen the strap slowly and let the jaw relax naturally. Do not yank it out.
How long can you wear an open mouth gag?
Most people start at around 10 to 15 minutes for the first few sessions.
As your jaw gets used to the position, you can gradually extend that time. Experienced users sometimes wear them for 30 to 45 minutes. Going beyond an hour is not recommended for most people.
Your jaw muscles will let you know when they have had enough. Soreness is normal after use. Sharp or intense pain is a sign to stop immediately.
After removing the gag, gently massage your jaw and open and close your mouth slowly a few times to help the muscles relax.
How do you clean an open mouth gag?
Clean your gag every single time before and after use. No exceptions.
The cleaning method depends on the material:
- Silicone: Wash with warm water and mild soap. You can also boil it for a few minutes if there is no electronic or metal parts.
- Stainless steel: Wash with warm soapy water or wipe down with a sex toy cleaner. Easy to sterilize.
- Hard plastic or acrylic: Warm soapy water. Do not boil or use harsh chemicals, as these can crack or degrade the material.
- PU leather straps: Wipe down with a damp cloth and a gentle cleaner. Do not soak or submerge.
- Rubber or latex: Rinse thoroughly with warm water and mild soap. These are harder to fully clean due to being porous.
Let everything dry completely before storing. Keep it in a clean bag or box away from other toys to avoid material reactions.
Pro tip: A dedicated sex toy cleaner is worth having. It is made specifically for this purpose and is safe on most materials.
What size open mouth gag should you start with?
For beginners, a smaller ring diameter is the right call. Something in the 40mm to 45mm range is manageable for most people.
Larger sizes, such as 50mm or more, create a wider opening and a more intense sensation. Those are better for people who have already gotten comfortable with the basics.
When it comes to the strap length, look for fully adjustable options. You want to be able to get a snug fit without the strap pressing uncomfortably into the sides of the face.
Starting smaller is always smarter. You can always work up to a larger size, but jaw fatigue from going too big too soon is not fun.
What is the difference between an open mouth gag and a ball gag?
A ball gag fills the mouth. An open mouth gag holds the mouth open without filling it.
Ball gags are about restricting speech and creating a sense of helplessness. Open mouth gags do the same for speech restriction but also keep the mouth accessible for oral play.
The physical sensation is also different. A ball gag puts pressure on the tongue and inside of the mouth. An open mouth gag puts pressure on the corners of the mouth and jaw muscles instead.
Neither is better than the other. It just depends on what kind of experience you are going for. Some people prefer one, some prefer both at different times. You can browse the full sex gags collection to compare styles side by side.
Is an open mouth gag good for beginners?
Yes, with the right approach. A silicone-coated O-ring gag in a smaller size is genuinely beginner-friendly.
The key things for beginners to get right are:
- Always have a clear stop signal agreed on in advance.
- Start with short sessions and increase time gradually.
- Choose a softer material like silicone to reduce jaw discomfort.
- Have a partner present. Solo use of gags is not recommended for beginners.
- Keep water nearby for after the session.

Frequently Asked Questions
Can you talk while wearing an open mouth gag?
Not clearly. Speech becomes slurred and hard to understand, which is part of the point for many people who enjoy this kind of play. That is exactly why a non-verbal safe signal, like a hand squeeze or dropping an object, is so important before you start.
Is drooling normal with an open mouth gag?
Yes, completely normal. Keeping the mouth held open means saliva builds up and drools. It is just how it works. Keep a towel nearby and make sure the person wearing the gag can always breathe clearly through their nose.
Can open mouth gags damage your teeth?
Hard metal rings pressed against teeth for long periods can cause discomfort or minor pressure marks. That is why silicone or silicone-coated options are recommended, especially for beginners. Avoid anything that feels like it is putting uneven or sharp pressure on specific teeth.
How do you store an open mouth gag?
Clean it thoroughly after every use, let it dry completely, and store it in a sealed bag or a dedicated storage box. Keep it separate from other toys, especially if they are made from different materials, to avoid reactions between materials over time.
Can you use an open mouth gag alone?
It is not recommended, especially for beginners. Having a partner present means someone can monitor your breathing, check in on comfort, and remove the gag quickly if needed. Solo gag use removes that safety net entirely.
What lube or products go well with gag play?
Gag play itself does not require lube. But if you are combining it with other toys during the session, a good water-based lube is the safest all-around option. Keep water nearby for after the session too, since wearing a gag tends to dry out the mouth and throat.
