Eliminate Morning Breath

and Break the Oral-Systemic Link


L’Oral™ Place and Forget®

Dental Probiotics

Here’s how it works:

Only L’Oral, with its 6-hour intraoral activity and multiple special probiotic strains freshens breath while fighting a wide range of oral health problems.


“Melts in your mouth — not in your gut”

With its unique, patent pending, AdherentPlace and Forget, Film-Forming feature, each lozenge time-releases its strains of dental probiotics into your mouth over six hours. Therefore you can even use it safely during sleep. Other brands of dental probiotic supplements do not have this long-lasting ability.

L’Oral sticks discreetly in your mouth, and slowly dissolves to form a spreadable probiotic film. The film protects its dental probiotic strains and keeps them growing within your mouth — not in your gut.

The good microbes spread throughout your mouth and colonize various niches: tongue, tonsils, throat, sinuses, teeth, gums, and cheeks. In these locations the probiotic microbes continue to grow and compete against bad dental germs. They crowd out bad, odorous germs and fight them for space to grow.

Over time (3 months or so) with repeated use and good oral hygiene practices, L’Oral’s dental probiotics can shift the population of microbes in your mouth toward better, friendlier microbes. More friendly oral microbes means fewer bad bugs in your mouth, naturally. That’s because bad dental germs make bad odors. And fewer bad germs means fresher breath and a healthier mouth. 

L’Oral™ Dental Probiotics is the first of a new class of multi-use, “Place-and-Forget“, adherent, dental synbiotic dietary supplements.

A synbiotic is a combination of probiotics and prebiotics. Probiotics are defined by the World Health Organization as  “micro-organisms that confer a health benefit on the host when administered properly”. Prebiotics are the preferred foods for the probiotics. Prebiotics keep the probiotics healthy while they are growing and doing their jobs.

“Place and Forget” adherence is the game-changing feature

Place a L’Oral™ in your mouth between a cheek and gums. Within 3 minutes the lozenge adheres discreetly and begins slowly dissolving. Then it feels so comfortable you essentially forget about it. You can even sleep safely with it. The total dissolution process averages about six hours, depending upon whether you use it during the day (3 hrs), or while sleeping (up to 8 hrs)..

Morning breath is caused by nighttime overgrowth of bad dental germs. Most dental germs that cause cavities and gum disease and smell bad, especially gum disease germs. By “fighting fire with fire” — pitting good probiotic microbes against pathogenic microbes — we can crowd out and reduce or eliminate bad germs that cause most common dental problems. Because you awaken with fresh breath, you know that the bad germs have not been growing much all night. Fresh morning breath means that more good probiotics have been growing than the bad germs.

In summary — because of the well-known oral-systemic link***, by fighting bad dental germs, we can break the links between dental problems and systemic problems.  Thus, by having fresher breath in the morning, you have fewer bad dental germs, fewer dental problems, and fewer links to systemic problems.

*** Oral health and systemic disease are intimately related but have remained, sadly, as isolated knowledge communities for decades. … it is noteworthy that bacteria form surface-attached communities on most biological surfaces, including the oral cavity. Biofilm-forming bacteria contribute to periodontal diseases and recent evidences point to roles of these bacteria in systemic diseases as well, with cardiovascular diseases, obesity, and cancer as notable examples.

1/18/2017: Note: The recommended dosage listed on the package is one L’Oral per day for the first month, and one L’Oral every other day thereafter; however, many people are getting good results with just half of the dosage. This is very good news indeed! This means the product is even more effective than we expected.
