Denture adhesive cream enhances the retention and stability of a denture that already fits reasonably well. This water-soluble material creates a temporary bond between the denture base and the gum tissue, helping to prevent slight movements that cause irritation and discomfort. While a properly fitted denture relies on natural suction, adhesives provide added confidence and security for many users, especially when eating or speaking. These products are intended only to supplement a good fit, not to compensate for a denture that is significantly loose or damaged.
Key Factors for Selecting an Adhesive
The choice of adhesive cream is highly individual, depending on a person’s lifestyle, level of comfort, and denture fit. Hold strength and duration are primary concerns, as users seek a product that keeps their prosthetic securely in place for an entire day without reapplication. Many cream adhesives are formulated to provide a secure hold lasting up to 12 hours, though some advertise a 24-hour duration.
The consistency and ease of application also play a significant role in user preference. Cream adhesives offer a strong, cushiony hold and are simple to dispense directly from a tube. However, creams can sometimes be messy and require thorough cleaning afterward. Alternatives like powders offer a lighter, less messy hold, and strips provide a clean application. Finally, the presence or absence of flavor and color should be considered, as many users prefer a taste-free product.
Understanding Safety Concerns and Ingredients
A primary consideration when selecting denture adhesive is the presence of zinc, an ingredient used to enhance the adhesive’s strength. While zinc is an essential trace mineral, chronic overuse of zinc-containing creams can lead to health issues. Excessive zinc intake causes a copper deficiency in the body, which is required for healthy nerve function and connective tissue maintenance.
Copper depletion can result in neurological disorders, including nerve damage, numbness, tingling in the hands and feet, and problems with balance and walking. The danger arises from the ingestion of massive amounts of adhesive by individuals attempting to secure ill-fitting dentures. To prevent this slow-onset nerve damage, users should choose zinc-free denture creams and consult a dentist if they need to use more than the recommended amount.
Step-by-Step Guide for Application and Removal
Proper technique is paramount for achieving the best hold and preventing adhesive overuse. Before application, the denture must be thoroughly cleaned and then gently dried, as moisture can hinder the adhesive’s bonding ability. The mouth should also be rinsed to ensure the gums are free of debris and lightly moisturized.
For application, the “less is more” rule is crucial. Apply the cream in three or four small dots or short, thin lines on the surface of the denture that will contact the gums. Avoid placing the adhesive near the edges, as this will cause it to squeeze out when the prosthetic is seated, indicating that too much product has been used. Once applied, press the denture firmly into place and hold it for several seconds to allow the bond to set.
To remove the denture, gently rock it back and forth to break the seal, which can be aided by first gargling with warm salt water. After removal, all residual adhesive must be cleaned from both the denture and the mouth tissues. Use a soft-bristled brush and a non-abrasive cleaner on the denture, and gently clean the gums, palate, and tongue with a soft cloth or brush to remove any remaining cream residue.
When Persistent Adhesive Use Signals a Need for Adjustment
Denture adhesive is intended to be a supplement, not a permanent solution for poor fit. If an individual needs to apply the adhesive more than once a day, or if a single tube of cream lasts for only a few weeks, it is a clear indication that the fit has deteriorated. The jawbone naturally changes shape over time following tooth loss, a process known as resorption, which causes the denture to gradually become loose.
Ignoring a loose fit and compensating with excessive adhesive can lead to chronic gum irritation, inflammation, and can accelerate the rate of underlying bone loss. When the fit is compromised, the denture may require a professional reline, rebasing, or complete replacement to restore comfort and function. Anyone noticing a significant change in stability, or an increased reliance on adhesive, should consult a dentist or prosthodontist immediately to prevent long-term oral health complications.
