“If I mess up my dental impression what do I do?”

Answer: No need to hit the panic button. If your first dental impression doesn’t go very well simply contact us. We will ship out a new dental impression kit to you. Hang on to your prepaid mailer as you will be needing that to mail back your new (better) dental impression.


Here’s a list of the most common errors when taking your own dental impression and some tips on preventing the mess ups:

  1. Attempting to take your dental impression before reading through all of the material and watching the video. Read our how it works page, and take a look at the instructions you receive in the mail.
  2. Took too long to mix the putty. As a result, the putty becomes hard before you submerge all of your teeth. Remember to set a timer and watch your time! Mix thoroughly and quickly for 40 seconds to 1 minute. Roll into hot dog shape (with a quickness) and place in the tray. With your finger, smooth out the areas as needed so you have a nice, smooth , equally distributed surface before submerging your teeth.
  3. Misjudged the position of the tray and the teeth hit the plastic wall. Here’s a great tip! Practice taking the empty tray in and out of your mouth several times before actually taking your teeth impression. Stand in front of a mirror and pretend the tray is already filled with putty. Try to keep the tray as straight as possible. Place the tray in the mouth and then push the bottom of the tray up (in a uniform, even manner). If you’re taking an impression for your lower teeth, follow the same process- You would just press the tray down instead of up. Make sure to submerge all of the teeth.

  4. Moving the tray once the teeth are submerged. This will result in a distorted dental impression and thus an ill-fitting mouth guard. Remember to submerge all of the teeth and stay still for the full 3 minutes before taking your impression out. Even if you’re drooling all over–STAY STILL!

  5.  Taking your tray out too soon. Removing the tray before the putty is completely set can cause some distortion. Remember 3 minutes!
