Insights from a 70-year dental laboratory veteran
When Richard Resk talks about dentures, he isn’t speaking from theory.
Resk has spent more than seventy years in the dental profession as a laboratory technician, ceramist, educator, and lab owner. He began his career after leaving the Air Force in the early 1950s, trained in dental laboratory technology in New York City, and eventually worked his way from apprentice to partner in one of Manhattan’s largest dental laboratories. Over the course of his career he built multiple laboratories, founded a dental technology institute in Manhattan, and trained technicians from around the world in advanced ceramic work.
Because of that background, his perspective on dentures focuses on something clinicians understand well but patients often overlook: comfort is not just a patient issue—it affects the entire workflow of a dental practice.
The adjustment cycle clinicians see every day
During a recent conversation about denture care, Resk described a pattern that dentists encounter regularly.
Even when a denture is fabricated correctly and delivered with a proper fit, patients frequently return with discomfort in specific areas. A small pressure point, irritation along the ridge, or soreness during chewing can be enough to bring someone back to the office.
From Resk’s perspective, these visits are part of the normal reality of denture care. Patients come back and say that a denture hurts in one spot or another, and the dentist must remove the appliance, identify the pressure area, relieve the surface, polish it, and place it back into the mouth.
Depending on the case, that process can easily take an hour of chair time.
If the irritation continues, the patient may need to return again for additional adjustments.
For busy practices, these appointments accumulate quickly.
Why lower dentures remain the biggest challenge
Throughout his career in dental laboratories, Resk worked closely with dentists and prosthodontists on the fabrication and refinement of dentures. One challenge he has consistently observed is the difficulty of stabilizing lower dentures.
Over time, mandibular bone resorption can significantly reduce the structural support available for retention. Implant-supported dentures have improved outcomes dramatically for many patients, but they do not eliminate the challenge of tissue adaptation.
Resk explains that lower dentures are consistently more difficult for patients to tolerate, even when implants are involved. Patients may still develop sore spots because the denture base places pressure on soft tissue that must adapt to the appliance over time.
In many situations, the issue is not a major flaw in the prosthetic but localized friction between the denture base and the mucosal surface.
Pressure and friction: the source of many complaints
After decades of working with dental prosthetics, Resk views many denture problems through a simple mechanical lens: pressure and friction.
When a rigid prosthetic rests against soft tissue, even small areas of concentrated pressure can lead to irritation. Over time, repeated movement and chewing forces can create soreness or inflammation in localized areas.
Reducing friction and distributing pressure more evenly can significantly improve patient comfort. In prosthetic medicine more broadly, introducing a thin buffer between a rigid device and soft tissue often improves tolerance and reduces irritation.
According to Resk, the same principle applies in denture care. When pressure points are reduced, many of the common complaints associated with dentures become less severe.
Adhesives solve one problem—but not always the right one
Many denture wearers rely on adhesives to improve retention. Adhesives can help hold a denture in place, but they do not always address the underlying cause of discomfort.
Over the years, Resk has also observed patients who struggle with the practical aspects of adhesives. Some report unpleasant taste, residue buildup, or messy application. Others find that adhesives improve retention but do little to relieve soreness caused by pressure points.
From a clinical standpoint, adhesives focus primarily on fixation, not necessarily cushioning.
For patients who are sensitive to irritation, improving the interface between the denture base and the tissue may be just as important as improving retention.
A different approach: moisture-activated cushioning
One concept that caught Resk’s attention when reviewing newer denture products is the idea of moisture-activated cushioning.
Rather than bonding the denture to the gum tissue with adhesive, this approach allows a thin material to absorb moisture in the mouth and expand slightly. The expansion allows the material to conform between the denture base and the mucosa, creating a cushioning layer that helps distribute pressure more evenly.
Resk describes the mechanism in simple terms. When two smooth surfaces come together with a thin layer of water between them, they create a natural seal. The cushioning material behaves in a similar way—expanding with moisture and helping stabilize the denture without relying on glue or paste.
In this case, the goal is not adhesion but pressure moderation and improved comfort.
Where cushioning can support clinical care
Resk emphasizes that cushioning systems are not intended to replace proper prosthetic fabrication or professional adjustments. Accurate impressions, proper design, and careful modification remain essential to successful denture treatment.
However, cushioning materials may serve as a supportive option in certain situations. These can include early adaptation periods after delivery, temporary tissue sensitivity, or patients who frequently develop localized sore spots.
By creating a buffer between the denture base and soft tissue, cushioning may help reduce friction and improve day-to-day comfort for some patients.
When patients experience improved comfort, they often adapt more easily to their dentures and may require fewer pain-driven return visits.
Comfort affects more than the patient experience
After decades spent working behind the scenes in dental laboratories, Resk has a clear view of how denture comfort affects clinical practice.
Patient comfort is obviously important for quality of life. But it also affects how often patients return to the office, how much chair time is required for adjustments, and how smoothly the schedule runs.
When irritation is reduced and patients adapt more easily to their dentures, the adjustment cycle becomes less disruptive for both the patient and the practice.
For clinicians, that can translate into fewer unscheduled visits, more predictable workflows, and better overall patient satisfaction.
After more than seventy years in the profession, Resk believes the concept is straightforward: when patients are more comfortable, they complain less, adapt faster, and require fewer adjustments. In the daily reality of clinical practice, that can make a meaningful difference.
