A healthy body starts with a healthy mouth

Everyone loves having a bright, shiny smile and fresh breath. But good oral health is more than cosmetics.

A growing body of research now shows that bacteria and inflammation in your mouth are linked to other problems, including heart disease, dementia, and diabetes and may affect your overall health.

Replenish the beneficial bacteria you need

Inside your mouth are billions of bacteria, bad and good. The bad bacteria cause gum disease and tooth decay. But the good help keep your teeth and gums healthy.

The delicate balance of bacteria in our mouths is constantly challenged by stress, medication, illness, what we eat and drink, and how often we’re able to brush.

ProBiora Health® oral care probiotics repopulates your mouth with the same “good” bacteria that are native to your mouth. They crowd out the harmful bacteria and restore the balance that’s so essential to your oral—and overall—health.

The Science of Probiotics — Restoring the Balance of a Healthy Mouth.

You may be familiar with probiotics for digestive and immune health. Probiotics use beneficial bacteria to replace harmful ones and promote health. ProBioraPlus® is the first probiotic powder specifically designed for your pet’s oral and dental care.

Villains and Superheroes in the Mouth

In the 1980s, a researcher named Jeffrey Hillman, PhD, DDS, wondered, “Is there a biological mechanism that helps counteract bad bacteria and, instead, promoted a healthy mouth?”

Conducting landmark research at the Harvard-affiliated Forsyth Institute in Boston and later at the University of Florida Dental School, Hillman discovered that there are “good” bacteria that can crowd out the “bad” bacteria and restore the natural balance of a healthy mouth.

From this discovery, Dr.Hillman created ProBiora3, a patented blend of beneficial “superhero” bacteria that crowd out the “villains” and support overall gum and tooth health. Now with 30 years of clinical research to back it up, ProBiora3 is the active ingredient in ProBioraPet and other ProBiora Health oral care probiotic products.

Harnessing Probiotics for Your Oral Health

The way ProBioraPlus oral care probiotics works is simple: Freeze-dried live microorganisms—“good,” or beneficial bacteria—are introduced to the mouth in the probiotic mint. As the mint dissolves in the mouth, the saliva hydrates the probiotic bacteria. They seek out their natural habitat, immediately migrating to the mouth tissue, gums, gum pockets and tooth surfaces where they will “live” and compete with the pathogens.

These beneficial bacteria restore the balanced oral biome that’s so critical to good oral health. Using ProBiora Health probiotics just once a day is all it takes to support healthier gums and teeth and fresher breath.

ProBioraXtra is easy to use

We made good oral health super simple. Just dissolve one ProBioraXtra mint in your mouth once a day. In 30 days or less, you’ll notice improved gum health, fresher breath and whiter teeth.

Frequently Asked Questions

What are probiotics?

Probiotics are live microbial organisms that are naturally present throughout the body. They are often referred to as “beneficial” or “good” bacteria. There are specific strains of probiotics that are beneficial for helping to make your pets’ breath fresher and promoting cleaner, whiter teeth. These probiotics are different from the good bacteria used to promote digestive health. The good bacteria in ProBioraXtra work by crowding out the bad bacteria that cause bad breath, resulting in fresher breath and cleaner, whiter teeth.

What’s the difference between ProBioraXtra and ProBioraPlus?

ProBioraXtra is an extra minty version of our product that contains Aspartame. Instead of a traditional bottle, it’s packaged in a blister pack, which is perfect for travelers and others on-the-go.

What are the ingredients in ProBioraXtra?

Isomalt, 100 Million cfu ProBiora3® Probiotic (streptococcus oralis KJ3®, streptococcus uberis KJ2®, streptococcus rattus JH145®), Calcium Stearate, Spearmint flavor (natural), Aspartame, Peppermint flavor (natural), Potassium Acesulfame, Sucralose, FD&C Blue 1. Soy-, wheat-, nut- and gluten- and dairy-free.

Is ProBioraXtra safe?

Yes. ProBioraXtra contains beneficial bacteria that are naturally found in healthy mouths. Our key ingredient, the ProBiora3 probiotic blend, contains only local-acting bacteria for the mouth; they do not interact as they go through the digestive process into the gut. There is nothing to break down or absorb. Its action is restricted to the tooth surface and the gum tissue.

Can I take ProBioraXtra if I am taking medication?

Yes. There are no known interactions between ProBioraXtra and medications. In fact, it is wise to use ProBioraXtra during and after a course of antibiotics, which can disrupt the bacterial balance in the mouth. As with use for any medication, it is suggested that you check with your Doctor/Dentist or Pharmacist for more information.

Can I give ProBioraXtra to my children?

Yes. ProBioraXtra is safe for all ages, however, since ProBioraXtra is a mint, it should only be given to children who are old enough to chew mints without risk of choking.

Do I need to take ProBioraXtra if I already take probiotics?

Absolutely. While other probiotics are designed for gut health, only ProBioraXtra contains the probiotics that support healthy gums and teeth, freshen breath and make smiles whiter and brighter.

Do I need to keep ProBioraXtra refrigerated?

No. ProBioraXtra is shelf-stable at room temperature. The beneficial bacteria in this revolutionary probiotic mint are freeze dried and activate on contact with your saliva.

What is the best way to use ProBioraXtra?

For best results, the ideal time to use ProBioraXtra is immediately after brushing your teeth, since brushing removes the surface particles and leaves the surface of your teeth in the best condition for the probiotics to attach and colonize. You can also use ProBioraXtra if you are unable to brush your teeth immediately after eating a meal and it will still provide positive results. The beneficial bacteria will help keep harmful bacteria in check. Just place the ProBioraXtra probiotic tablet in your mouth, let it fully dissolve naturally, and you’re ready to go! It’s like having a portable mouth rinse. ProBioraXtra is also simple for traveling, as it’s not a liquid and it does not require refrigeration.

Will ProBioraXtra make my gums and teeth sensitive?

No, not only will ProBioraXtra not make your gums and teeth sensitive, it will actually help to support the health of your gums and teeth. Fast-acting conventional whiteners using high concentrations of harsh, chemical hydrogen peroxide for short contact times, create tooth sensitivity and can cause gum inflammation. This high concentration of harsh, chemical hydrogen peroxide and other chemicals is hard on teeth and can create pitting (rough surface textures) and etching, making otherwise healthy teeth more prone to staining. The beneficial bacteria in ProBioraXtra naturally produce low levels of hydrogen peroxide that create continual contact with the teeth, whitening without sensitivity or gum irritation. ProBioraXtra is the only complete oral care probiotic for 24 hour a day coverage.

Is ProBioraXtra safe for dentures, caps, crowns, braces, dental appliances and sleep aids?

Absolutely. Unlike other commercially available whitening products, the ProBioraXtra probiotic mint is completely safe and effective for use with dentures, veneers, caps, dental bridges, crowns, braces, dental appliances and sleep aids. It’s also a great way to provide additional support in maintaining gum and tooth health for those who wear oral braces.

How long until I see results?

ProBioraXtra starts to work immediately. Most customers notice a difference within 30 days of use.

If I am a tobacco user will I get benefits from ProBioraXtra?

Yes, ProBioraXtra is an ideal product for tobacco users. ProBioraXtra can help decrease some of the oral health problems created by tobacco use, especially yellowing, stained teeth.

Do I need mouthwash if I am using ProBioraXtra?

No. ProBioraXtra is a safe, effective and economical way to replace all mouthwashes, breath fresheners and tooth whitening products.

Can I chew the ProBioraXtra mint and still get benefits?

The targeted probiotics contained in the ProBioraXtra probiotic mint are released as the mint dissolves in the mouth. For best results, avoid chewing the mint and allow it to naturally melt in the mouth. If you choose to chew and break the mint, allow the smaller pieces to dissolve in your mouth without swallowing them.

“Probiotics in dental treatment are so important! Because unfortunately when we treat our dental patients, we kill the good bacteria as well as the bad. So to put them on ProBioraPlus, is just a wonderful and natural way to rebuild those good bacteria”

—Patti DeMatteis, ASDH, RDH

“Any dentist that is looking to not only achieve periodontal health for his/her patients, but keep it that way should definitely look at this product”

As Dr. Witt Wilkerson says, it’s “like sending in the good troops to drive out the bad.” Watch Dr. Wilkerson and other leading dentists talk about why ProBiora Health oral care probiotics are right for you.
