How to Use the GrindGuardPM Nightguard Dental Self-Impression (S-IS) Kit

This important first step is how GrindGuardPM will get an impression of your teeth from which we will make your custom fit night guard.

Please read through ALL the instructions BEFORE starting the impression process. Please complete two sets of impressions.

After completing these instructions, you will have two dental impression molds of your teeth that will be returned to us using the provided pre-paid shipping box (U.S. Customers Only). We will evaluate both impressions and determine which is the better of the two. From that impression, your form-fitting night guard will be crafted and shipped back to you.

You should receive your mouthguard in 2 – 3 weeks. If you have questions or problems, please contact customer service.

IMPORTANT: Please store and use in a room temperature below 80℉. If you are unsure if your impression is good on the first try, email us a picture and we will evaluate it and offer tips for success before you make the second impression. Be sure to complete and return both impressions. Our dental lab technician will decide which will work best. If after two tries you still need help you can order another set of impression material.

CAUTION: Do not use with braces, removable dental appliances, or loose teeth. If under 18, adult supervision is recommended.

Decide Which Tray is a Proper Fit
Place each tray in your mouth to determine which offers the best fit. Choose the tray that you can comfortably bite down upon with your molars contacting the bottom of the tray and your lips extending over the front of the tray.

Practice Inserting and Removing the Tray from Your Mouth
Place the tray in your mouth AT LEAST 3-4 times until you are comfortably and effortlessly able to contact your molars to the bottom of the tray and get your lip over the front.

Prepare to Take Your Impression
Carefully remove the putty from both packets taking care that the putties don't come in contact with each other or the tray. With all the contents of the kit close together, the impression process will go smoothly. Have a 2 minute timer available.

Begin the Impression Process
Take both putties and knead them together. Mix them together as quickly as possible until they are combined into one solid color (there should be no white streaks). This should take no longer than 30 seconds.

As soon as the putties have been properly mixed, immediately roll the uniform putty into a log shape that can evenly cover the arch of the tray. As soon as the putty has been properly placed into the arch of the tray, insert the tray the exact same way as you practiced in step 2.

Continue the Impression Process
Push the tray into your teeth by pressing the BOTTOM of the tray (NOT the handle) until your molars have made contact with the tray. The putty should wrap all around your gum line. Is is important to not allow the tray to shift position once properly inserted in your mouth. Once in place, gently hold the tray in your mouth for 2 minutes. After 2 minutes, remove the tray and impression with both hands by gripping the handle with your index and middle finger, and your thumbs underneath your front teeth. (It should take a bit of effort to pull out).

Inspect Your Impression
Check your impression for a few critical properties. The putty is one solid color. At least one molar is visible in the impression. The gum line is clearly visible above each tooth including at least one molar and the putty is firmly set in the tray.

Make Second Impression
If you are unsure if your first impression is suitable, email us a picture and we will evaluate it and offer tips for success before you make the second impression.

Return Both Impressions
Be sure to complete and return both impressions. Our dental lab technician will decide which will work best.
