Before you get started, take your teeth photos

In addition to your impressions, a key part of starting teeth straightening with clear aligners is taking teeth photos.

Our lead orthodontist, Dr. Tania Aguilar and her team need to see photos of your teeth to design your clear aligner treatment and to ensure that your teeth are suitable for clear aligners.

These are the photos that you need to take as part of the Impression Kit process. You can easily upload these photos to your dashboard via the My Account tab on our website before doing the impressions.

Teeth photos we need from you

Take the following teeth photos before you start your impressions.

Upload them to your Wondersmile dashboard. Then our orthodontists can access them and use as a reference when designing your clear aligner treatment plan to ensure you get an accurate plan that will get you straighter teeth.

Our lead orthodontist needs to see your teeth. Upload your teeth pics before your impressions.

How To make your best impression

Step 1: Brush and floss your teeth

Brush your teeth for 2 minutes. Then floss to remove any food or plaque that may be stuck between your teeth.

Step 2: Wash your hands

Before moving onto step 3, wash your hands thoroughly with soap and water.

Step 3: Take teeth photos with the retractor

With the handle facing down, squeeze the retractor inwards and slide it in to fit the grooves of your mouth. Take your teeth photos and when you are able to, upload them to your WonderSmile account.

Photos we require from you:

  • Lower Arch

  • Upper Arch

  • Open Smile

  • Closed Bite Smile

  • Natural Smile

Step 4: Brush, floss, wash, and glove up

Like step 1, brush and floss your teeth before you get started. Good hygiene is important so make sure that you also wash your hands!

This is the lower tray. The upper tray and lower are different. Be sure to use the correct tray.

Step 5: Take out your trays and putty

Take out one set of trays (1 x upper and 1 x lower) and four putty containers (2 blue and 2 white). Start with the upper tray.

Step 6: Mix Putty

Mix one blue and one white putty together until they are one solid colour. Once you start mixing, you’ll have to be quick! The putty mixture takes 60 seconds to set and you'll need to get it onto the tray as quickly as possible.

Step 7: Place putty into the impression tray

Roll the solid colour putty mix between your hands to create an even cylinder around 4 inches/10cm long. Place the putty roll into the upper tray, making sure to fill the entire U-shape tray evenly.

Step 8: Make your impression

Wait 2 seconds before placing the tray in your mouth and push it up onto your teeth with a normal amount of pressure (not too hard but not too soft). Hold the tray using your thumbs to ensure it doesn’t move while making your impression and bite down gently until light contact is made with the putty on the tray. Set your timer and wait 3 ½ minutes.

Important to remember

  • Make sure not to drag the tray when removing it from your mouth. The best method for the upper tray is to pull down, then pull out and for the lower tray is to pull up, then pull out.

  • Removing the tray can be a bit messy, so have your towel on hand to wipe up any excess saliva

Step 9: Make your bottom impression

Repeat steps 6 to 8 for your lower arch.

Step 10: Send photos for review

Before starting your second set of impressions, take photos of the two impressions you completed (1 x upper and 1 x lower) and send them to us at We’ll respond if there’s anything you need to change for your second set and answer any of your questions or concerns. Once you've heard back from us, it’s time to repeat the process.

Step 11: Do it again!

Repeat steps 4 to 9 for your second set.

Step 12: Post impressions to WonderSmile

Send all 4 impressions back to WonderSmile using the pre-paid label or envelope provided.

Once complete, you’re on your way to a perfect smile!
