Many denture wearers find themselves wondering why chewing gum often proves a frustrating experience. The simple answer is that dentures, unlike natural teeth, lack the same surface texture and moisture that allows gum to adhere effectively. This article will delve into the science behind this phenomenon, exploring the reasons why gum clings to natural teeth but not dentures, and offering helpful tips for denture wearers who still want to enjoy the occasional piece of gum.
What Makes Gum Stick to Teeth?
Before understanding why gum doesn't stick to dentures, it's important to know how it adheres to natural teeth in the first place. Gum's stickiness is primarily due to its composition. Many gums contain a variety of polymers and resins that create a sticky, viscous substance. These substances interact with the saliva and the slightly rough surface of natural teeth, forming a bond. The moisture present in saliva acts as a lubricant, initially allowing the gum to be malleable, but then aiding in the adhesion process once the gum starts to soften and form a seal. The microscopic irregularities in tooth enamel provide further points of contact, strengthening the bond.
Why Doesn't Gum Stick to Dentures?
Dentures, typically made of acrylic or other similar materials, possess a significantly smoother surface than natural teeth. This smoothness minimizes the surface area available for the gum's sticky components to adhere to. The lack of microscopic irregularities means there are far fewer points of contact for the gum to grip. Furthermore, dentures often don't fit perfectly against the gums, leaving gaps that prevent a complete seal. This is exacerbated if the denture is loose or ill-fitting. Finally, the lack of natural saliva production under the denture (compared to natural teeth) also plays a crucial role. The reduced moisture limits the interaction between the gum and the denture surface, hindering the adhesion process.
What are the different types of dentures? Do they all have the same adhesion issues with gum?
The type of denture – full or partial – doesn't fundamentally alter the adhesion problem with chewing gum. Both full and partial dentures share the common characteristics of a relatively smooth surface and an absence of the microscopic irregularities found on natural teeth. The fit of the denture is a more significant factor. A poorly fitting denture, regardless of whether it's full or partial, will always have significantly poorer adhesion of gum than a well-fitting denture.
Can I use special adhesives to help gum stick to my dentures?
While denture adhesives are designed to help the denture stay in place against the gums, they are not formulated to improve the adhesion of chewing gum. Their purpose is to create a barrier and cushion, preventing movement of the denture itself. They won't make the surface of the denture rough enough to make gum stick effectively. Trying to use denture adhesive for this purpose may not be very successful, and could lead to an unpleasant, sticky mess.
Are there any types of gum that stick better to dentures?
Unfortunately, no gum is specifically designed to stick to dentures. The inherent properties of denture materials always make successful gum-chewing difficult. The best approach is to consider alternatives if you desire the chewing action and flavor.
What are some alternatives to chewing gum for denture wearers?
Several alternatives offer similar sensory experiences without the frustration of gum sticking issues. Sugar-free candies, breath mints, or even gum specifically designed for people with dental issues (though these still may not adhere well to dentures) are good options. Consult your dentist for tailored recommendations.
Conclusion
The inability of gum to stick to dentures is primarily due to the smooth surface of the dentures, the absence of natural tooth texture, and the reduced saliva production under the denture. While there aren't any foolproof solutions to make gum stick effectively, understanding the reasons helps manage expectations and explore alternatives. Always consult your dentist for personalized advice regarding denture care and suitable chewing alternatives.
