Mouldable Dental Impression Tray Instructions

These trays inside your teeth mould kit are mouldable. Please follow the instructions below on how to use them.

  1. 1 Start with either the upper or lower tray and place the tray inside your mouth.
  2. 2 Once inside your mouth, feel for where the tray is tight on your gums or teeth.
  3. 3 If it feels tight somewhere, boil some water and place the trays inside the water for 15 seconds, then remove them.
  4. 4 Bend the tray to make it more comfortable inside your mouth.
  5. 5 Now continue with the rest of the instructions below.

Home Dental Impression Kit Instructions

1

Select the Correct Tray

Choose the correct impression tray for either your upper or lower impressions. Stand in front of a mirror.

💡 Pro Tips:

  • Wash your hands thoroughly before handling the putty
  • Work in a well-lit area at room temperature
2

Open the Putty

Open one set of putty — one purple and one white. Ensure your hands are clean to prevent dust or dirt from contaminating the putty.

💡 Pro Tips:

  • Keep putty sealed until you're ready to use it
  • Don't mix colours from different sets
3

Mix the Putty

Use your fingers to mix the impression material into a uniform colour which should be purple. It is best to do this within 45 seconds or less.

💡 Pro Tips:

  • Work quickly — the putty starts setting after about 2 minutes
  • Mix until there are no streaks visible
4

Load the Tray

Roll the mixed putty into the shape of a log. Lay the log in the upper/lower tray in a 'U' shape that mimics the shape of your teeth. Do not smash down. The log should go all the way to the back of the tray.

💡 Pro Tips:

  • Push putty right to the edges of the tray
  • Remove any excess that might cause gagging
5

Position in Your Mouth

Place the tray in your mouth so your teeth are positioned over the centre of the putty log. For the upper tray, press the tray straight up with your thumbs for around 2 minutes without moving. For the lower tray, use your index fingers instead.

💡 Pro Tips:

  • Keep your lips relaxed and slightly apart
  • Breathe normally through your nose
6

Hold Still for 2 Minutes

Keep perfectly still while the putty sets. Don't talk, swallow excessively, or move your jaw. The putty needs to capture an exact imprint of your teeth and gums.

💡 Pro Tips:

  • Set a timer on your phone
  • Distract yourself by watching a video
7

Remove Carefully

Open your mouth and pull the tray straight down (for upper) or up (for lower) to remove it.

💡 Pro Tips:

  • Don't twist or bend the impression
  • Pull straight out to avoid distortion
8

Repeat for Second Arch

Repeat the procedure with the other lower or upper tray. Take your time – it's better to get it right than to rush.

💡 Pro Tips:

  • Wait until your first impression is fully set
  • Use the same technique for consistent results
9

Send Photos for Approval

When finished with the impressions, please send a photo of them with your order number to Photo@retainersathome.co.uk to verify them before posting them back to us. Please use the subject line 'photo' and your order number.

💡 Pro Tips:

  • Wait for our approval before posting back
  • Take clear, well-lit photos of both impressions
Don't worry if the first impression is not perfect. In your kit, there is an extra set of putty to try again.

Video Consultation Available

Troubleshooting Common Issues

Putty is setting too fast

Work in a cooler room. Cold temperatures slow the setting time. You can also briefly chill the putty in the fridge (not freezer) for a few minutes before mixing.

First impression isn't perfect

Don't worry! Each kit includes an extra set of putty, so you can try again if your first attempt isn't quite right. Follow the instructions carefully and use our video guide if needed.

Can't see back teeth clearly

Push the tray further back before biting down. The tray should cover all your teeth, including your wisdom teeth if you have them.

Gagging sensation

Try breathing through your nose and focusing on a point in front of you. You can also try tilting your head slightly forward.

Impressions not approved

If your impressions are not approved, we will provide feedback and suggestions on how to improve them. We're committed to helping you get it right to receive the best possible retainers.
