gumline medical

"Plaque is a sticky film produced by bacteria that attaches to teeth and especially along the gumline."

The gumline is the visible edge where the soft gum tissue meets the teeth, like the frame around a picture. For investors, it matters because changes at the gumline — such as recession, inflammation or infection — are indicators of oral health trends and can affect demand for dental treatments, consumer products, and related medical claims or regulatory reviews, influencing revenue and risk for companies in healthcare and consumer sectors.

sonic toothbrush technical

"Sonicare brand, the #1 Dental Professional recommended sonic toothbrush brand worldwide, is marking World Oral Health Day..."

A sonic toothbrush is an electric toothbrush that uses very fast vibrations of the brush head to move bristles and fluid, loosening plaque and debris from teeth more effectively than a manual brush. For investors, it matters because product technology, perceived health benefits and regulatory claims drive consumer demand, pricing power and brand differentiation in the crowded oral-care market—think of it as a faster, more efficient tool that can change buying habits.

March 20th, Philips Sonicare invites New Yorkers to rethink their nightly clean with an inside look at what happens in your mouth while you sleep

CAMBRIDGE, Mass., March 17, 2026 /PRNewswire/ -- Royal Philips (NYSE: PHG, AEX: PHIA) and its Sonicare brand, the #1 Dental Professional recommended sonic toothbrush brand worldwide, is marking World Oral Health Day by declaring it World Oral Health Night drawing attention to a common risk to your oral health many people overlook: assuming manual brushing always removes enough plaque.

The science shows why this moment before bed is so important.

Research reviewing 59 studies shows that manual brushing can leave up to 50% of plaque behind.¹ Plaque is a sticky film produced by bacteria that attaches to teeth and especially along the gumline. It acts as a protective layer that helps bacteria cling to the mouth and continues to grow.

"At night, much of the plaque and bacteria in the mouth builds up quietly and often goes unseen and unnoticed," said Matina Vidalis, Regional Business Unit Leader, Oral Healthcare, Philips North America. "World Oral Health Night challenges one of the most routine habits in people's day. When you see what manual brushing can leave behind, you start to expect more from your toothbrush. Sonicare is designed to clean what manual brushing can't."

Bringing the hidden world of nighttime oral health to life

For one night, March 20th, World Oral Health Day becomes World Oral Health Night, turning the spotlight on what happens in your mouth after you go to bed.

Philips Sonicare is bringing this hidden reality to life with a bold public installation in New York City, March 20th, 2-8 p.m. ET at Lavan Midtown, where visitors can explore a multi-sensory installation that reveals what brushing manually leaves behind. Audiences will be guided through the science while immersive visuals creatively demonstrate the microscopic activity taking place along teeth and the gumline every night.

"As a dentist, I see firsthand in patients how bacteria growth and improper brushing can lead to plaque, inflammation and systemic health issues. The Night Switch experience by Philips Sonicare reveals what manual brushing leaves behind and why brushing with a Philips Sonicare power toothbrush makes such a difference," said Dr. Sharon Huang, DDS, MICOI. "This isn't just about a cleaner smile, it's about empowering people to take control of their oral health and protect their overall wellness. When you feel what truly effective cleaning means, you never go back to manual brushing."

Good night care starts with Sonicare

Sonicare technology is designed to reach the areas manual brushing often misses. Sonicare power toothbrushes are designed to remove up to 2000% more plaque² than a manual toothbrush, powered by up to 62,000 bristle movements per minute. In addition, Sonicare Fluid Action supports the bristles to clean by driving fluid deep between teeth and along the gumline.

New this year, the Philips Sonicare 6500 builds on this technology, removing 1000% more plaque³ versus a manual toothbrush, helping users maintain a cleaner mouth before going to sleep.

Philips Sonicare's mission is to improve the oral health of millions of people by making superior care accessible to all. Through consumer-centric innovation and education, the business aims to democratize better oral healthcare with our strategic partners because it is the gateway to overall health.
