TheraBreath™ Unveils Eight Clinical Research Studies at IADR 104th General Session, Demonstrating Superior Gum Health and Oral Care Benefits for New TheraBreath™ Toothpaste
The landscape of professional oral hygiene underwent a significant shift during the 104th General Session of the International Association for Dental, Oral, and Craniofacial Research (IADR), held from March 25 to 28, 2026, in San Diego, California. TheraBreath, a prominent brand within the Church & Dwight oral care portfolio and the leading alcohol-free mouthrinse brand in the United States, presented a landmark series of eight clinical research studies. This comprehensive clinical portfolio marks the brand’s formal entry into the high-performance toothpaste category, providing rigorous, science-based evidence for its new product line. The data presented underscores a pivotal transition for TheraBreath, moving from a niche leader in breath freshening to a scientifically validated powerhouse in comprehensive oral health.
The research presented at the IADR session focused on several critical pillars of dental care, including gingival health, plaque prevention, malodor reduction, teeth whitening, and enamel protection. Most notably, the clinical findings demonstrated that the TheraBreath Healthy Gums Toothpaste significantly outperforms established market leaders, specifically Crest Regular, across multiple clinical markers. These markers include the reduction of gingival inflammation, the prevention of plaque biofilm accumulation, the mitigation of gingival bleeding, and the long-term control of oral malodor. By establishing this clinical foundation, Church & Dwight aims to provide dental professionals with the empirical data necessary to recommend TheraBreath toothpaste with the same level of confidence previously reserved for the brand’s well-known mouthrinses.
A Chronological Shift: From Specialized Rinse to Clinical Portfolio
The journey toward the 2026 IADR presentation began in earnest in 2021, when Church & Dwight Co., Inc. acquired the TheraBreath brand. Founded over 30 years ago by Dr. Harold Katz at the California Breath Clinics, TheraBreath was originally developed to address the root causes of halitosis without the use of harsh alcohols or artificial flavors. Under the stewardship of Church & Dwight, the brand has undergone an aggressive expansion, integrating into a broader oral care ecosystem that includes Waterpik water flossers, ARM & HAMMER toothpaste, and Spinbrush toothbrushes.
The development of the toothpaste line was a multi-year endeavor intended to translate TheraBreath’s signature oxygenating technology into a stable, effective paste delivery system. Throughout 2024 and 2025, the Church & Dwight Research and Clinical Affairs team, led by Dr. Annahita Ghassemi, Senior Director of Global Product Safety and Clinical Research, conducted a series of independent clinical trials. These trials were designed to meet the rigorous standards of the IADR, the world’s premier organization for dental research. The culmination of this research was the unveiling of eight distinct posters in San Diego, representing the first full clinical portfolio for the TheraBreath toothpaste line.
Analysis of Clinical Data: Superiority in Gingival Health
The centerpiece of the TheraBreath presentation was the comparative data regarding the "Healthy Gums" variant of the new toothpaste line. In head-to-head clinical trials, researchers evaluated the efficacy of TheraBreath Healthy Gums Toothpaste against a standard fluoride toothpaste (Crest Regular). The results indicated a statistically significant advantage for the TheraBreath formulation in several key areas of periodontal health.
Gingival Inflammation and Bleeding
The studies utilized the Gingival Index (GI) and the Bleeding on Probing (BOP) metric to assess the health of the soft tissues. Participants using the TheraBreath formulation showed a marked decrease in redness and swelling of the gingiva compared to the control group. Furthermore, the reduction in bleeding sites was significantly higher, suggesting that the toothpaste’s active ingredients and delivery system are highly effective at disrupted the inflammatory processes associated with early-stage periodontal disease.
Plaque Prevention
Biofilm management is the cornerstone of preventive dentistry. The IADR posters detailed research into plaque accumulation over a specific period. TheraBreath’s toothpaste demonstrated a superior ability to inhibit the formation of dental plaque. This is particularly relevant for patients prone to gingivitis, as the reduction in plaque directly correlates to a decrease in the bacterial load responsible for gum irritation.
Malodor Control
Building on the brand’s heritage, the new toothpaste line was tested for its ability to neutralize volatile sulfur compounds (VSCs), the primary cause of bad breath. While standard toothpastes often rely on masking scents, the TheraBreath clinical data showed a sustained reduction in VSC levels for hours after brushing, outperforming the control toothpaste in both immediate and long-term malodor control.
The Scientific Team and the IADR Presentation
The presentation in San Diego was a collaborative effort involving the top tier of Church & Dwight’s R&D department. The team included Mr. Joe Vazquez, Principal Scientist of Clinical Affairs; Dr. Garvin Peters, PhD, Principal Scientist of Product Development R&D; Mr. Anthony Cirigliano, Senior Manager of Product Development R&D; Dr. Oliver Chen, PhD, Associate Director of Global Clinical Affairs; and Dr. Elisabeth Memin, PhD, Principal Scientist of Product Development R&D.
Dr. Annahita Ghassemi emphasized the importance of the venue for these revelations. "IADR is where the dental research community sets the standard for evidence-based care," Ghassemi stated during the session. She noted that these eight studies mark a "turning point" for the brand, bridging the gap between consumer experience and clinical validation. The goal was to provide dental clinicians—dentists and hygienists—with the hard data required to make evidence-based recommendations to their patients.
The eight posters presented covered a wide spectrum of dental concerns:
- Gum Health: Detailed comparative analysis of gingival indices.
- Plaque Inhibition: Long-term studies on biofilm reduction.
- Malodor Neutralization: Measurements of VSC reduction over time.
- Enamel Protection: Studies on the remineralization potential and acid resistance of the fluoride delivery system.
- Whitening Efficacy: Assessment of surface stain removal without high abrasivity.
- Sensitivity Relief: Clinical trials on the toothpaste’s impact on dentinal hypersensitivity.
- Dry Mouth Symptoms: Evaluation of the toothpaste’s compatibility with xerostomia patients.
- Comprehensive Oral Microbiome Impact: Research into how the formulation affects the balance of oral flora.
Implications for the Dental Industry and Consumer Market
The introduction of a clinically-backed toothpaste line from TheraBreath has significant implications for both the professional and retail sectors. For decades, the toothpaste market has been dominated by a few legacy brands. TheraBreath’s entry, supported by data showing it outperforms a "gold standard" like Crest Regular in specific categories, introduces a new level of competition focused on specialized health outcomes rather than just general cleaning.
For dental professionals, the availability of these studies provides a new tool for patient home-care regimens. As dental hygienists increasingly look for products that address specific patient needs—such as chronic gingivitis or persistent halitosis—the TheraBreath portfolio offers a documented alternative to traditional formulations. The emphasis on being "alcohol-free" and using "science-backed" ingredients aligns with a broader consumer trend toward "clean" health products that do not sacrifice efficacy for safety.
Furthermore, the data regarding enamel protection and whitening suggests that TheraBreath is positioning its toothpaste as a "total care" solution. By proving that the product can protect enamel while also improving gum health and breath, Church & Dwight is attempting to capture a larger share of the premium oral care market.
