My jaw feels relaxed and I sleep deeper!

"I’ve tried several guards before and was always let down 😞. But after just a few nights, I noticed a real difference — my jaw feels more relaxed, I wake up without tension, and I’m finally sleeping through the night. Even my morning headaches have become less frequent. I’m excited to see how it helps with long-term use!"

How to Wear your Night Guard

Feel the difference overnight, enjoy the benefits for life.

Rinse Before Use

Before wearing, rinse your night guard with cold or lukewarm water to remove any dust or debris.

Insert the Guard Gently

Place the night guard over your upper or lower teeth (whichever it’s designed for). Gently press it into place with your fingers until it fits snugly.

Check for Comfort

Make sure the guard feels secure but not tight. Your teeth should not feel pressure or pain. It should stay in place without effort.

Wear Overnight

Use your night guard every night while you sleep to protect against grinding and clenching. Consistent use gives the best results.

Clean After Each Use

In the morning, rinse the guard with cool water and gently brush it with a soft toothbrush (no toothpaste). Let it air dry completely before storing in its case.

Since I started using my Retainers Direct night guard, I sleep through the night without clenching or grinding. I used to wake up with a sore jaw and stiff neck almost every morning. That’s completely gone now. It’s amazing how much of a difference something so simple can make!

My dentist quoted me $450 for a custom night guard. I found Retainers Direct online and decided to try it instead—and I’m so glad I did! The process was smooth, the instructions were clear, and the fit is incredible. I’ve been using it every night, and it’s held up great. Can’t believe the quality for the price!

I've been using this night guard for about 4 months now, and it still feels like new. It's flexible enough to be comfortable but firm enough to protect my teeth. I love that it doesn't shift around at night. I barely notice I’m wearing it, which was never the case with store-bought guards. Will definitely reorder when I need a new one.

I’ve struggled with teeth grinding for years and have gone through so many over-the-counter guards. They were all either too bulky or just didn’t work. Retainers Direct changed the game. The impression kit was simple, and the night guard that came back fits like it was made by my dentist. No more sore jaw, no more headaches. Highly recommend it to anyone who grinds their teeth!

I’ve been dealing with teeth grinding for a long time and nothing seemed to help. I tried so many over-the-counter guards, but they were uncomfortable and ineffective. Then I found Retainers Direct, and it’s been a total game changer. The custom-fit night guard I received was easy to order, and the fit is perfect—like it was crafted just for me. No more waking up with a sore jaw or painful headaches. I couldn’t be happier with the results and highly recommend it to anyone who suffers from teeth grinding!
