G•U•M® PerioShield™ Oral Health Rinse

This oral health rinse has received FDA approval as a medical device and is available over the counter.

Americans agree that taking care of their mouth, teeth, and gums is “absolutely needed” (80%); however, only one third of them claim they do an “excellent” job of caring for their mouth, teeth, and gums (33%), and fewer still say their oral health is “excellent” (26%).1 Brushing twice daily for 2 minutes and flossing once daily are singularly consistent recommendations made by oral healthcare providers, but despite their relative simplicity, patients often fail to adhere to even these recommendations.


Sunstar Americas, Inc., has recently launched a unique oral health rinse, GUM® PerioShield™ Oral Health Rinse, a new and innovative aid for the prevention and treatment of gingivitis, which can lead to periodontitis (Figure 1). With 29 scientific studies backing the product, this launch further establishes Sunstar’s role in providing clinically proven solutions to dental professionals.

What makes PerioShield unique? It works by disrupting existing biofilm, making it easier to remove, and coating the teeth and gums to prevent new plaque from sticking. It has a proprietary ingredient, delmopinol hydrochloride 0.2%, and a unique mechanism of action that helps prevent the formation of new plaque. Delmopinol (a morpholinoethanol derivative) is an amine alcohol that functions as a surface-active agent shown to interact with pellicle constituents and inhibit glucan synthesis by Streptococcus mutans.2 It has little or no demonstrable effect on the bacteria, but it interferes with plaque/biofilm matrix formation, which makes it easier to remove. The interference with plaque matrix formation inhibits the ability of bacteria to produce polysaccharides, which is the “glue” and nourishment necessary for plaque bacteria to thrive and proliferate (Figure 2 and Figure 3).

With this unique mechanism of action, PerioShield received FDA approval as a medical device and is available over the counter. The rinse creates an invisible protective shield around the teeth and gingiva to continually repel plaque and pathogenic bacteria—thus the name PerioShield.

Because the rinse is not bactericidal, but disrupts the development and maturation of the harmful biofilm while maintaining a good oral flora, it is a very attractive proposition for patients concerned about antimicrobial resistance and maintaining equilibrium of the oral ecosystem.

While PerioShield can be used by any patient group, the ideal candidates are patients with gingivitis who can benefit from stopping the progression of periodontal disease at its earliest stages. It can also be used as a relapse prevention tool for post-chlorhexidine treatment and at-home maintenance therapy after scaling and root planing. PerioShield is also right for any patient who can benefit by maintaining a healthy, balanced oral flora.
