Pro B Fresh Review: Does It Relief Bad Breath?

Have you heard of probiotics and how they can help you with conditions like gastrointestinal problems, obesity, mental health, and overall well-being? If not, you may have searched for probiotics for better health on Google.

In fact, one study found that prebiotics and probiotics are the third most commonly used supplements among adults, following minerals and vitamins.

Probiotic-based nutritional supplements have skyrocketed in popularity in the last decade due to their popularity in treating various health conditions.

Several studies and new research have started finding out that probiotic-based supplements can help to fight bad breath and overall benefit your oral health.

Pro B Fresh is a dental probiotic supplement that is specifically designed to treat your oral health by removing bad bacteria while maintaining good bacteria in your mouth. It contains specific probiotic strains that will benefit your oral and dental health.

In our full review of Pro B Fresh, we thoroughly studied the science behind its ingredients, side effects, benefits, and other factors so you can decide if it’s right for you. 

Let’s start exploring right away.

What is Pro B Fresh?

Pro B Fresh is a probiotic supplement that claims to fight and prevent bad breath and is designed to assist people with poor oral/dental health.

Pro B fresh is marketed as a supplement specifically for your dental and oral health, unlike other probiotics that are promoted for overall health.

The product claims that its targeted oral probiotic strains of beneficial bacteria, such as S. salivarius K12, L. reuteri, and L. paracasei, can help with the aforementioned benefits.

It contains a proprietary probiotic blend as well as a variety of other ingredients.

When manufactured, the Pro B Fresh contains 3 billion live bacteria colony-forming units (CFUs) and an effective level of bacteria (1 million CFUs) “until the best by date,” according to the label.

Pro B fresh should be taken once or twice daily after brushing your teeth or using mouthwash.

They also claim that their tablets have very long shelf lives and do not need to be refrigerated on a regular basis.


Not much is known about the manufacturer of Pro B Fresh. The company has a poorly designed official website that fails to provide many important details. 

The only thing we know about Pro B Fresh from their official website is that they have corporate offices in Canada, Australia, and the United Kingdom. 

We don’t believe the manufacturer makes any other products besides Pro B Fresh because their homepage lacks a shop or store page. 

The manufacturers also claim to offer a money-back guarantee of 90 days. 

Pro B Fresh Benefits And Uses

The chewable Pro B Fresh has benefitted many users with oral and dental issues, which suggests it does have some benefits that you might be seeking. 

Pro B Fresh’s benefits and some of its uses include:

  • It can prevent bad breath and provide a fresh feel every time you use it. 
  • Can help reduce symptoms of gingivitis and periodontal disease.
  • The probiotics used promotes oral health and maintain a good oral flora. 
  • Pro B Fresh dental probiotics can help eliminate the problems related to tonsils.
  • Besides adding freshness to your morning breath it can defend against gum infections and tooth cavities. 

That was all for the benefits the dental probiotics may provide you. As you see it’s mainly used for two purposes i.e. bad breath and tonsils.

You can always take one Pro B Fresh tablet in the morning to kickstart your day with a fresh breath that will long throughout the day.

Ingredients Making Pro B Fresh

Pro B Fresh uses a proprietary blend of probiotics that provides 3 billion CFUs per serving.

The four bacteria used in the blend are Lactobacillus paracasei 8700:2, Lactobacillus reuteri, Lactobacillus acidophilus, and Streptococcus salivarius BLIS K12.

Because Pro B Fresh contains a proprietary blend, it is difficult to determine whether clinically active amounts of probiotics are included.

With this in mind, clinical studies and research on these strains/bacteria have been discussed below.

1. Lactobacillus paracasei (8700:2)

L. paracasei, which is similar to other strains of Lactobacillus bacteria like L. rthamanos and L. Casei, is frequently used in the fermentation of dairy products.

By lowering oral streptococcus levels, the bacteria linked to tooth decay, this bacterial species may offer caries protection.

One randomized trial found that taking 100,000 CFU/g Lactobacillus paracasei reduced inflammation levels.

According to one study, L. paracasei showed antibacterial properties when combined with fermented skim soy milk.

2. Lactobacillus reuteri

Another strain of prebiotic used in the Pro B Fresh tablets is L. reuteri. This strain produces antimicrobial molecules that can inhibit pathogenic microbes’ colonization. 

Studies have found that a decrease in L. reuteri abundance can lead to inflammatory diseases in humans. 

Another study using Lactobacillus reuteri on oral health indexes found that the group which received L. reuteri noticed an improvement in plaque, gingivitis, and bleeding. However, the results achieved were not statistical. 

3. Lactobacillus acidophilus

This bacteria is mainly found in your intestine and helps your body break sugar like Lactose into lactic acid. 

It prevents the flourishment of bad bacteria in your gut and protects you from conditions like vaginal yeast infection and diarrhea. 

In the mouth, L. acidophilus can promote the growth of good bacteria and can prevent them from developing in the oral cavity. Not much research has been done on L. acidophilus for oral health.  

4. Streptococcus salivarius BLIS K12

The last strain of probiotics in Pro B Fresh tablets is the Streptococcus salivarius which is mainly found in your oral cavity and contributes to the establishment of immune homeostasis. 

A study published in the year 2021 concluded that Streptococcus salivarus K12 inhibited immune activation by pathogens during periodontal disease.

Some other reports and studies have also found S. salivarius K12 to decrease the incidence of tonsils in children. 

Thus, Streptococcus salivarius K12 can be considered a powerful strain for oral health and preventing tonsils in children as well as adults. 

Ingredients Conclusion:

Pro B Fresh contains some probiotic strains that are useful for your oral health and may decrease the abundance of bad bacteria causing foul breath. However, few of the ingredients lacked enough human studies to convince if they can really promote the health of your oral cavity and gums.

Does Pro B Fresh Work For Dental Health?

There is no one answer to it. It’s because Pro B Fresh is a dietary supplement and not a drug. Thus the results can vary among individuals.

Still, looking at the results and after evaluating the ingredients we have a positive view of the dental probiotic.

Pro B Fresh contains four different strains of Lactobacillus bacteria each of which is linked to your oral health.

Some have antibacterial properties which in turn can inhibit the growth of bad bacterias and prevent bad breath conditions.

Also, strains such as Streptococcus salivarius have proven to improve conditions of gingivitis, bleeding, and tonsils. 

Thus, you can expect Pro B Fresh to improve your oral health and solve the problem of bad breath.

Pro B Fresh Possible Side Effects

ProB Fresh is free of soy, gluten, wheat, nuts, sugar, artificial color, or preservatives, and is non-GMO, which means it is unlikely to cause allergies.

Although they do not state the side effects of taking this supplement on their official website, some people may experience some side effects from taking Peppermint and Spearmint.

When first starting out with any probiotics-based supplement it may cause mild side effects including safe tools, gas, nausea, bloating, abdominal cramping, and taste disturbance (1).

For example, Lacticaseibacillus Paracasei and Lactobacillus Acidophilus in this supplement can cause side effects such as increased gas and bloat, but these effects are well tolerated and these two are safe for 9 months.

Lactobacillus reuteri side effects include difficulty breathing, severe dizziness, rash, itching, and swelling of the throat, tongue, and face.

Allergic reactions from Lactobacillus reuteri are uncommon but if you experience any, consult your doctor immediately or discontinue use of this supplement.

Side effects from Peppermint and Spearmint include nausea, abdominal pain, dry mouth, heartburn, sleepiness, and slowed breathing. Also. Sedative medications can cause breathing difficulties and excessive sleepiness.

Before beginning any new supplement, as with any other, it is best to consult with your healthcare practitioner.

Cost And Where To Buy

Pro B Fresh is available for purchase at only two places, their official website and at Amazon. But we don’t recommend you to buy it from their official website. 

It is because we don’t think the official website is legit and maintained by the owners of the supplement. Also, there’s no detail provided about the founder and its manufacturer.

Amazon is the best place where you can buy Pro B Fresh dental probiotics. There it costs you $34.98 per bottle. Each bottle contains 30 servings (1 tablet a day).

  • The dental probiotics come in form of chewable tablets making them easy to ingest.

Who Should Buy Pro B Fresh?

To be clear Pro B Fresh can be used by anyone who wants to experience fresh breathing. But we personally think some specific people must consider this product. 

You should buy ProB Fresh in case –

  1. You are experiencing a really bad breath and if that worries you.
  2. Anyone suffering from gum disease, periodontal disease, or cavities.
  3. You have tonsils and that troubles your voice and gives foul breath.

Pro B Reviews: What Users Experienced?

As you know the dental probiotic Pro B Fresh is available only on Amazon and it’s the official website for purchase. You can get your hands only on the reviews at these places. 

Now, since we do not trust the official website very much, we must not consider the reviews. It is always best to go with third-party reviews as on amazon

If you take a look, most positive reviews point towards Pro B Fresh helping people deal with the problem of bad breath. While some people also reported it to be effective for their tonsils.

People who were happy with the product mentioned in the Pro B Fresh reviews that it simply didn’t work for them and is a waste of money.

Why don’t listen to them directly? Here are a few important Pro B Fresh reviews you should consider before making a purchase.

Amazon Customer says –

OMG!! If you have those awful disgusting tonsil stones stop here! I am a super clean human being and have had tonsil stones for years. I’ve tried everything under the sun and was just about to give up until I came across dental probiotics. I have been shocked that I have not had one. They are the most disgusting thing ever on earth and this product truly works. You have to get past the weird taste and stick with it I chew one every morning after I brush my teeth and every night after I brush my teeth. I have not had tonsil stones in two weeks which is completely rare this absolutely works!

Scrump says –

This is my 2nd bottle and I am really happy with this product. You just pop one in your mouth in the morning after brushing your teeth. They have a slight mint flavor and melt in your mouth within 10 minutes. I feel like my mouth is in better condition and I don’t have bad breath anymore. I will continue to order this product.

One Lady says –

Just save your money and buy some probiotics with 10 different strains the results would be better. This is what I ended up doing.

Araceli Sandoval says-  

I received this item and the Expdate is 3/2022 I tossed it immediately and would like a refund as soon as possible. I asked my Dr. and he said never to take anything that has expired.

Final Verdict: Should You Buy Pro B Fresh?

While human research on dental probiotics is still in its early stages, many customer reviews have found that Pro B Fresh provides the claimed benefits.

According to some research, the lactobacillus strains and probiotic strains included in ProBfresh may help to prevent bad breath and improve overall oral health.

Customer reviews of Pro B Fresh appear promising, but a clinical study is required to provide more certainty about the claimed benefits.

Furthermore, Pro B Fresh is less expensive than other dental probiotic supplements with comparable benefits. Given its lower price point, Pro B Fresh appears to be a good place to start when considering any of these products.

This supplement may not be safe for some people because it has not been tested by a third party and some of its ingredients can cause side effects, allergic reactions, and symptoms.

So, before taking Pro B Fresh or other supplements, consult with your doctor to ensure that they are appropriate and safe for you.
