What happens during a dental impression procedure?
When making dental impressions, your healthcare provider may use traditional dental putty or digital dental impressions. While the outcomes are similar, the procedures are different.
Traditional dental putty
During this procedure, your healthcare provider dispenses a putty-like dental impression material into plastic or metal trays. Next, they’ll place the trays over your teeth. After a minute or two, the dental impression material sets and hardens. Finally, your healthcare provider removes the trays (and impression material) from your mouth.
Your impressions are then sent to a dental laboratory. There, a technician will pour stone into your dental impressions to create a cast of your mouth.
Digital dental impressions
Many dental offices now have the ability to take digital dental impressions. During this procedure, your healthcare provider uses a digital handheld wand to capture thousands of pictures of your teeth and gums. As your healthcare provider passes the wand over your teeth, images of your mouth will come up on a computer screen. Next, the computer software will stitch the images together, creating a digital, 3D representation of your dental arches. There’s no need for putty when taking digital dental impressions.
Your healthcare provider will then electronically deliver your photo files to a dental lab. There, a technician will begin working on your case.
How long does a dental impression take?
If you’re having impressions made with traditional dental putty, the material usually sets in about three to five minutes. Overall, a dental impression procedure takes about 15 minutes or less.

Do dental impressions hurt?
In most instances, there isn’t any pain from putty impressions. However, they can trigger a gag reflex in some people, which can be uncomfortable.
Can dental impressions pull teeth out?
The majority of the time, dental impressions don’t pull teeth out. But if you have teeth that are already loose due to trauma or severe gum disease, it could happen. Your dentist will talk with you about this possibility and address the problem if it happens.
What should I expect after my dental impressions are taken?
Once your dental impressions are complete, your healthcare provider will send them to a laboratory. A trained dental technician will begin working on your case.
This process can take anywhere from one week to several weeks, depending on your specific situation. For example, if you need one dental crown, it usually takes less time compared to someone who needs multiple crowns. Processing times can also vary due to geographical location and how many cases the lab is working on at the time.
If necessary, your dentist can place a temporary restoration while you’re waiting on your case to be completed. This is common practice for people who are missing a front tooth. That way, you won’t have a gap in your smile in the meantime.
Are there risks associated with dental impressions?
Generally, there aren’t any major risks associated with dental impressions. But some people have a gag reflex that’s triggered by the dental impression procedure. In these cases, your dentist can work with you to minimize discomfort.
As mentioned, teeth that are already very loose can potentially come out in the impression material. This is rare, but your dentist will help you find a solution if this should happen.
