Learn the correct way to insert and remove your NightAdvantage night guard, plus tips for a comfortable fit and long-lasting care.
A custom-fit night guard is a smart investment for protecting your teeth from grinding and clenching while you sleep. But getting the most out of it starts with knowing how to put it in and take it out correctly. Improper insertion or removal can cause discomfort, reduce the guard's lifespan, or even damage it.
The NightAdvantage night guard is designed to fit snugly over your teeth, offering a comfortable yet secure fit. In this guide, we'll walk you through the step-by-step process of inserting and removing your NightAdvantage guard, along with essential fitting and care tips to keep it in top condition.

Before You Start: Prepare Your Night Guard
Before inserting your NightAdvantage guard, make sure your hands are clean and dry. Wash them with soap and water to avoid transferring bacteria to the guard. Also, inspect the guard for any debris or damage. If you've just received your guard, it's a good idea to rinse it under lukewarm water before the first use.
If you have any dental appliances or braces, consult your dentist before using a night guard. The NightAdvantage is designed for natural teeth, and using it with braces may require a different type of guard.
- Always handle the guard with clean hands.
- Rinse the guard with lukewarm water before first use.
- Check for any rough edges or cracks before insertion.
How to Insert Your NightAdvantage Night Guard
Inserting your guard correctly ensures a comfortable, secure fit that stays in place all night. Start by holding the guard with both hands, ensuring the U-shaped groove is facing up. Align the guard with your upper teeth, gently pushing it into place. You should feel it snap over your teeth with a slight pressure.
Once in place, bite down gently to seat the guard fully. It should feel snug but not painful. If you feel any sharp edges or excessive pressure, remove the guard and try again. It's normal to have a slight adjustment period, but the guard should not cause soreness.
If you have a lower night guard, the process is similar but reversed. Place the guard over your lower teeth and press upward. Always follow the specific instructions provided with your guard.
- Align the guard with your teeth before applying pressure.
- Bite down gently to seat the guard fully.
- If it feels too tight, remove and reinsert after a moment.
How to Remove Your NightAdvantage Night Guard
Removing your guard properly is just as important as inserting it. In the morning, gently loosen the guard by using your thumb and index finger to rock it back and forth. Avoid pulling directly on the guard, as this can cause it to bend or crack.
Once the guard is loosened, carefully lift it off your teeth. If it feels stuck, rinse your mouth with water to create a bit of moisture. Never use tools or force to remove the guard, as this can damage both the guard and your teeth.
After removal, immediately rinse the guard under lukewarm water to remove saliva and debris. Store it in a protective case when not in use.
- Rock the guard gently to break the seal.
- Never pull hard or use tools.
- Rinse and store the guard after each use.
Tips for a Comfortable Fit
A well-fitted night guard should feel almost invisible once you're used to it. If you experience discomfort, try adjusting the guard's position or ensure it's fully seated. Some users find it helpful to insert the guard a few minutes before bedtime to allow your mouth to adjust.
If your guard feels too loose or too tight after a few nights, contact customer support. The NightAdvantage is custom-fit from your dental impressions, so it should fit perfectly. Never try to modify the guard yourself, as this can ruin its effectiveness.
For those who grind severely, you might consider a more robust option like the Custom-Fit Hybrid Night Guard - Dual Arch, which offers extra protection. But for most, the NightAdvantage provides excellent comfort and durability.
- Insert the guard a few minutes before sleep to adapt.
- If discomfort persists, contact support.
- Avoid DIY adjustments to the guard.
Caring for Your Night Guard
Proper care extends the life of your NightAdvantage guard and keeps it hygienic. Clean your guard daily with a soft toothbrush and mild soap or a denture cleaner. Avoid using hot water, as it can warp the material. Rinse thoroughly before reinserting.
Store your guard in a ventilated case when not in use to prevent bacterial growth. The retainers-case-403328">Retainers case is a great option, but any breathable container works. Keep it away from direct sunlight and extreme temperatures.
Replace your guard as recommended by your dentist or when you notice signs of wear, such as cracks or thinning. Regular check-ups ensure your guard continues to fit properly.
- Clean daily with mild soap and a soft brush.
- Store in a ventilated case.
- Replace when signs of wear appear.
Inserting and removing your NightAdvantage night guard correctly is simple once you get the hang of it.
