The only two issues you may find uncomfortable while getting a dental impression are the taste of the alginate material and the potential triggering of your gag reflex. The impression material does not have flavor added, so its natural flavor only lasts while the impression is in your mouth. Feel free to ask your dental professional for a sip of water or a swish of an antibacterial mouthwash once it's out.
If you're concerned about your gag reflex, you're not alone! Many people are nervous about getting a dental impression because of the expectation of a foreign material having to sit at the back of their mouth for a few minutes. But did you know there are things you can do to mitigate the chances of triggering your gag reflex? Try breathing through your nose or asking your dental professional if you can sit up during the procedure (reclining can put your throat in an awkward position). These are a few practices that can help you feel more comfortable in the quick time it takes to have your impression completed.
Note that your dental professional may deem it necessary to place a temporary crown, bridge, or dentures once your impression is ready. This is because there may be some lag time of a few weeks while your permanent appliance is completed by a dental laboratory and sent to your dental office. But this will all depend on the reason why you're getting your dental impression in the first place!
We think you'll find your dental impression experience to be pretty fast and effortless. The purpose of dental impressions is to create an exact mold of your tooth or teeth for restorations, orthodontic appliances, or prosthodontic treatment. So even if the process of getting your dental impression may seem a bit uncomfortable or is something you're not looking forward to, the end goal of a healthy, pain-free smile is worth it!
