One of the most common concerns people have before ordering a custom night guard online is the impression process. Taking your own dental impressions sounds complicated. It is not. With the right kit and clear instructions, most people complete the process in about ten minutes and get a usable result on the first attempt. This guide walks through exactly what happens, what you are trying to achieve, and the most common mistakes to avoid.
What You Are Actually Trying to Do
A dental impression creates an accurate negative of your teeth and gums. The lab uses this to build a night guard that follows the exact contours of your mouth. The better the impression, the better the fit. You do not need any dental training to do this. The putty material used in at-home kits is forgiving, sets at a predictable rate, and the trays are sized to fit most adults. What matters is working confidently and without rushing.
What Comes in the Impression Kit
Your DentalNightGuard.com impression kit includes everything you need. When it arrives you will find impression trays (upper and lower, sized for most adults), putty in two separate containers that you mix together, mixing instructions, a return envelope for sending impressions back, and a timing reference. Do not open the putty containers until you are ready to take impressions. The mixed putty has a working time of roughly two minutes once combined.
Before You Start
A few things to do before opening the kit.
Brush and rinse first
Food particles in the impression affect the result. Take impressions after brushing or at minimum after rinsing thoroughly.
Read the full instructions once
Go through the instructions completely before touching the putty. The material has a limited working window and you want to move through the process without pausing to re-read.
Practice your bite position
You will need to bite down naturally and hold steady for about 90 seconds. Practice biting down and staying still before the putty is in your mouth. A relaxed, natural bite is what you want, not a forced jaw position.
Do one arch at a time
Upper first, lower second, with a few minutes between to allow the first impression to fully set before you handle it.
Step-by-Step: Taking the Upper Impression
Step 1: Mix the putty
Take equal amounts from both putty containers and knead them together until the colour is completely uniform, with no streaks. This typically takes about 30 seconds of active mixing. The moment it is uniform, move immediately to the next step.
Step 2: Load the tray
Press the mixed putty into the upper impression tray, filling it evenly across the length. You want it filled but not overflowing significantly. Smooth the surface lightly with a finger.
Step 3: Seat the tray
Position the tray at your upper teeth and press up firmly, making sure it seats evenly on both sides. You should feel the putty contacting all your upper teeth and your gum line. Press up and hold steady.
Step 4: Hold and wait
Hold the tray completely still for 90 seconds. Breathe through your nose. Do not talk or move your jaw. If the tray shifts, the impression will be distorted.
Step 5: Remove cleanly
After 90 seconds, break the seal by pressing your finger between the tray rim and your gum line on one side, then remove with a straight downward pull. Do not wiggle it side to side.
Step 6: Check the result
Look at the impression. You should see a clear, detailed negative of all your upper teeth, including the spaces between teeth and the gum line. If teeth are missing from the impression or the result is shallow, you may need to retake it. The kit includes enough material for this.
Repeat for the Lower Impression
Allow five minutes before repeating the process for your lower teeth. The lower impression follows the same steps. For the lower, you press the tray upward from underneath, making sure it seats against all lower teeth. Lower impressions are slightly trickier because the tongue naturally wants to move. Try resting your tongue against the roof of your mouth while the putty sets.
Common Mistakes and How to Avoid Them
Mixing too slowly
The putty starts to set the moment it is mixed. Slow mixing wastes your working time and can result in a partially set impression that did not seat properly. Mix quickly and decisively.
Moving during the set
Any movement while the putty is setting creates distortion. Ninety seconds of stillness is all it takes.
Biting too hard
Biting forcefully rather than naturally creates a compressed impression that does not reflect your true bite position. A natural, relaxed bite is the goal.
Forgetting to check the impression
Check both impressions before sending them back. Missing teeth, shallow detail, or visible distortion are reasons to retake before returning the kit.
After Your Impressions Are Done
Package both impressions in the provided return envelope and send them back. From the moment the lab receives your impressions, your night guard is typically ready and shipped within 5 to 7 business days.

It is better to retake than to receive a guard that does not fit well. [Internal link: Contact DentalNightGuard.com]
