Periodontal disease is common all over the world, With the World Health Organization classifying it as a major public health problem due to its high prevalence and associations with systemic chronic diseases, such as cardiovascular disease, diabetes and respiratory diseases.
In China, weight is particularly acid. A combination of poor oral hygiene, high -use tobacco, nutrition issues and limited access to preventive dental care means that gum disease hits early and often. Among adults aged 25 to 44 years, about 87% have bleeding gums and 97% had software accumulation – both early signs of gum disease 1.
“In order to improve population -level results, the challenge is to make existing oral hygiene habits to do more,” says Henglong Hu, head of R&D in Haleon China, the World Consumer Health Company.
Instead of focusing on the treatment of symptoms of gum disease, Haleon research teams work with academic and clinical experts to explore how to enhance daily oral care can prevent the onset of the disease. Their work ranges from laboratory plaque formation studies and targeted antimicrobial therapies in clinical trials, which are designed to understand which treatments work in the real world.
Root
Long before the gums begin to bleed, the dental plates – a type of biofilm – begin to form. This dense, structured matrix of bacteria and extracellular substances accumulates along the line, tightly sticking to the surfaces of the teeth – as well as the ringing around a kitchen drain. The plaque activates low quality inflammation in the gum tissues, signaling the older stage of gum disease, known as gingivitis.
“The inflammation is present, but the pain is intermittent and mild. Most people do not realize the damage until it is too late,” Hu says. If left untreated, plaque accumulation can proceed with complete periodontitis, with irreversible damage to the bones and connective tissues that hold the teeth in place. This can also lead to persistent bad breath, gum recession and tooth loss. The relationship between gum disease and chronic diseases such as diabetes is also a cause of concern.
“The most effective daily brushing allows us to intervene before the problems get worse,” Hu explains. However, standard toothpaste compositions have struggled to fight the plaque. Many toothpastes are designed to relieve symptoms such as bleeding or swelling, instead of disturbing biofilm, Hu adds.
Paved
In their research on alternative toothpaste compositions, Haleon researchers turned to their attention to the sodium bicarbonate, a compound used in oral care since the 19th century. “Darcard has long been part of dental compositions,” Hu says. “But his full potential is now being reviewed with modern experimental tools.”

To study the effect of high concentrations of sodium-carbonate on plates of different maturity, the researchers used a firm depth membrane-a laboratory device that allowed them to develop biofilm under constant flow of artificial saliva.
In laboratory crops of 7 and 14 -day plates, sustainable bacteria were reduced by about 1,000 times after a two -minute treatment with sodium polyc, leaving only 0.1 % of the original population2. Interestingly, the pulp was not effective in 2 -day plates.
The microscopy explained the trend: the newer biofilm had a multi -layer “fortress” architecture, while the ripe biofilm had collapsed in secluded bacterial clusters less closely closely connected to the surface of the teeth.
“The bacterial does not kill bacteria,” Hu explains. “Instead, the extracellular polysaccharides is broken down that sticks to the mature plate together, making it easier to remove with brushing without disturbing the overall microbial balance.”
Constant
But achieving a stable toothpaste with such high concentrations of sodium bicarbonate has raised significant technical challenges. For example, the formulations were difficult to mix and the researchers observed unexplained color changes in the paste.

They carried out a series of sloping projections within the technically feasible range. The wording with 67% sodium bicarbonate showed a favorable balance between efficiency and biofilm stability. Basically, it remained compatible with fluoride – active in toothpaste to prevent the cavity and enhance the enamel – which was difficult to incorporate into high active loads. Sensory properties were another limitation-high concentrations of sodium bicarbonate produce a strong salty metallic taste.
“We tried more than twelve prototypes with different profile sensors,” Hu recalls. “It took multiple rounds of adaptation to operation and acceptance of balance without attenuating the integrity of the wording.”
From the installation of the wording, Haleon has performed more than 15 randomized testing tests throughout North America, Europe and Asia, writing more than 5,000 participants with mild to moderate gingivitis. For example, a six -month test in the United States, examined the effect of brushing twice a day with 67% binar toothpaste on toothpaste and gingivitis3.
“We have watched the effects not only in controlled regulations but also in populations and geographical areas,” Hu adds.
A separate meta-analysis reviewed seven independent studies that investigated the use of 67% sodium bicarbonate in the plaque and gum health. The analysis compared the compositions with and without 67% sodium bicarbonate in periods of 12 and 24 weeks, examining the differences in plate levels, gum bleeding and signs of gum inflammation4.
Start
Hu and his team continue to investigate how oral care can shift in the direction of the previous and more targeted prevention of gum disease. A research program is exploring formulations that could alter the oral microbicide in order to balance the bacterial populations to promote a healthier oral environment. Target antimicrobial approaches – designed to selectively inhibit the pathogenic bacteria without disturbing the beneficial – are also under investigation.
In the meantime, in response to consumer demand and environmental sustainability, the Haleon research team explores the naturally derived ingredients and environmental awareness strategies, such as a reduction in the amount of non -recycled plastics used, the investigation of alternatives.
With so many research paths to explore, the Haleon team also examines how to accelerate future discoveries. The future project will use AI to predict and optimize the combinations of ingredients according to the oral microbicide that is common in a particular area, Hu says.
Haleon may have myriad innovations in his conductor, but the ultimate goal is not just to explore new ingredients of toothpaste and delivery systems, Hu says. It incorporates these innovations into daily oral hygiene routines where gum disease begins quietly.
