What happens if I mess up my replacement retainer impression?

What happens after you take your replacement retainer impression?

Once you complete your impression, take clear photos of it and send them to the Caspersmile team for review.

If something looks wrong, you’ll be advised to make a new impression before sending it. If the impression is approved, you’ll be told to ship it back. Our team then manufactures your retainer based on the impression and ships it to you within 3 weeks.

What makes an impression unusable?

Minor imperfections do not always mean your impression will be rejected. The team checks whether it has enough accurate detail to be used. Certain problems, however, can make an impression unsuitable for producing a replacement retainer:

Missing or incomplete teeth

The impression should capture all the teeth that need to be represented in your retainer. Missing or incomplete teeth can leave important information out of the impression and make it unsuitable for production.

Large air bubbles

A few tiny bubbles may not cause a problem. Large air bubbles can cover important tooth details and make the impression difficult to use.

Tears or pulled areas

Tears, stretched sections, or pulled areas can change the shape of the impression. If these defects affect important tooth surfaces, the impression may need to be retaken.

Distortion

If the material becomes distorted while you are taking it out or handling it, the resulting shape may no longer represent your teeth correctly.

Impression material shifts during setting

The material needs to remain stable while it sets. If it shifts during this time, it can distort the captured tooth details and affect whether the impression can be used.

Can I fix a mistake in an impression?

Once the impression material has set, do not try to reshape, patch, smooth, or otherwise alter it.

If you notice a significant problem, make a new impression rather than trying to repair the existing one.

If you’re planning replacement retainer ordering, having a fresh impression ready can help you avoid unnecessary delays if your first one isn’t usable.

How to get a better impression the second time?

If you need to retake your impression, focus on the steps most likely to prevent another redo:

Don’t worry if you make a retainer impression mistake

If your impression isn’t accurate enough, it will be identified during the review process before your replacement retainer is made. You’ll be guided on what needs to be corrected and can retake the impression if necessary.

Taking a little extra care when making your impression can help prevent unnecessary delays and ensure your replacement retainer is made from an accurate impression.
