How Technology is Making Dental Impressions More Comfortable for Children

Medically Reviewed by Esteem Dental And Orthodontic Team on September 22, 2026

Digital scanners have replaced the gooey, uncomfortable putty trays that once made dental impressions one of the most dreaded parts of a child’s visit. A small handheld wand now captures a precise 3D model of a child’s teeth in a few painless minutes, with no gagging, no waiting for material to set, and no mess.

At Esteem Dental’s pediatric team, we introduced digital scanning specifically because so many children struggled with traditional impression trays. Seeing how much calmer appointments became once we made the switch is part of why we continue investing in technology built around comfort, not just accuracy.

What Makes Traditional Impressions Difficult for Children

Traditional dental impressions require a child to bite into a tray filled with alginate putty and hold still while it sets, usually for several minutes. For an adult, this is mildly unpleasant. For a young child with a developing gag reflex, a tray that extends toward the back of the mouth can trigger choking sensations, panic, or tears well before the material has finished setting.

Children who have a strong reaction to one impression often carry that fear into every future dental visit, even ones that involve no impression at all. That lingering anxiety is one of the main reasons pediatric practices have moved so quickly toward digital alternatives.

How Digital Scanners Work

A digital intraoral scanner looks and feels more like a small camera wand than a dental tool. As a dental assistant glides it gently over the teeth, the device captures thousands of images per second and stitches them together in real time into a 3D model that appears on a nearby screen.

Children can often watch their own teeth appear on the monitor as the scan happens, which turns a procedure that once felt invasive into something closer to a game. Many scanners are designed with smaller, rounded tips specifically sized for a child’s mouth, and the entire process for one arch typically takes only a few minutes, compared with the 10 to 15 minutes a traditional impression can require once the material is mixed, placed, set, and removed.

What the Research Shows About Comfort and Accuracy

The comfort difference between the two methods is not just anecdotal. A 2024 randomized crossover trial published in the International Journal of Paediatric Dentistry compared digital scans directly against conventional alginate impressions in children and adolescents and found that the digital technique produced significantly higher comfort scores and a smaller gag response in the same patients tested both ways.

Beyond comfort, digital impressions offer several practical advantages for young patients:

• No bulky trays: the scanner wand is small enough to move freely around the mouth without triggering a gag reflex.
• Faster appointments: most scans take a few minutes per arch rather than the extended set time traditional putty requires.
• Immediate quality checks: a dentist can review the scan on screen right away and rescan a single area instead of redoing an entire impression.
• Fewer remakes: because the scan captures fine detail with fewer distortions than putty, appliances built from it tend to fit correctly on the first attempt.

Taken together, these findings are part of why digital scanning has become the standard of care in many pediatric and orthodontic practices rather than an occasional upgrade.

What This Means for Orthodontic and Restorative Treatment Planning

Impressions are not just a one-time step. They form the basis for orthodontic treatment planning, retainers, and appliances like space maintainers that hold room for permanent teeth after a baby tooth is lost early. A more accurate starting model means fewer adjustment visits and appliances that fit correctly from the first delivery. This matters most for families following the latest advances in orthodontic technology, since the American Association of Orthodontics recommends children see an orthodontist by age 7, and an early evaluation almost always starts with an impression.

Digital files also travel easily between our team and any dental lab fabricating an appliance, which shortens the turnaround time between a child’s scan and the day their retainer or aligner tray is ready.

Preparing Your Child for a Digital Scanning Visit

Most children adjust to digital scanning quickly, but a little preparation still helps, especially for a child who has had a difficult experience with a traditional impression in the past. Letting your child know the scanner is a small camera rather than a mold, and that they can breathe normally and take a short break at any point, tends to ease most first-time nerves.

If your child has significant dental anxiety unrelated to impressions, our team also walks families through how to prepare for a first dental visit more broadly, since building comfort with the chair, the lights, and the sounds of the office often matters as much as the specific procedure being done that day.

The Future of Pediatric Dental Impressions

Scanning technology continues to improve. Some systems now flag any area of the scan that may need a quick redo before the child even leaves the chair, cutting down on rescans days later. Portable and wireless scanners give our team more flexibility to work around a child who has trouble sitting fully upright, and some practices are experimenting with simple on-screen animations that give children something engaging to watch during the scan itself.

None of these advances replace attentive, patient chairside care, but they do make it easier for children who once dreaded impressions to get through the appointment calmly.

Schedule Your Child’s Next Appointment at Esteem Dental

Our team uses digital scanning as a standard part of pediatric care because it consistently produces a calmer visit and a more accurate result than the impression trays many parents remember from their own childhoods. Whether your child needs a routine checkup, a retainer, or a first orthodontic evaluation, a digital scan is typically the first and easiest step.

With offices in both Lake Nona and Winter Garden, we make advanced pediatric dental technology accessible to families throughout Central Florida. To schedule an appointment and see the difference modern scanning technology makes, please visit our contact form.
