It works!
I recently started using this product two days ago, and I must say, it works like magic. I usually suffer from bad breath, especially after not talking for a while and when I wake up in the morning. However, for the past two days, my breath has been fresh all day long. I'm genuinely impressed and will definitely be ordering again—this is going to be a monthly must-have for me!

Great!
Fabulous product. I've never had such healthy gums and noticed a great difference after only 3 weeks. No more bleeding gums and less plaque. Stains have disappeared too. It's easy and convenient to use. The customer service is excellent and orders are dispatched and delivered quickly.

I have been looking for this sort of product for years now, even purchased a similar product from the US, which was not nearly as good, also I had to stop taking it as it gave me an upset tummy. So overjoyed with this product, I take it at bedtime and just let it slowly dissolve in the mouth. My breath has improved enormously and my teeth seem to be healthier, which is brilliant. I will take it forever! Thank you!

What Are Dental Probiotics and How Do They Work?​

If you’ve struggled with bad breath or gum issues, you’re not alone. You’ve probably turned to mouthwash, chewing gum, or even extra brushing to keep your breath fresh.

Sound familiar?

Well, here’s the truth. These only mask the problem—they don’t fix it.

The real cause of persistent bad breath and bleeding gums is actually an imbalance of bacteria in your mouth. When harmful bacteria outnumber the good ones, they release foul-smelling gases and contribute to gum disease, plaque build-up, and other oral health issues.

This is where dental probiotics come in.

Unlike gut probiotics, which work in your digestive system, dental probiotics are designed to work in your mouth. They introduce good bacteria that naturally compete with the bad ones, helping to restore balance to your oral microbiome.

Once they colonise your teeth, gums, and tongue, these beneficial bacteria help reduce odour-causing microbes and improve overall oral health. This is the key.

Brushing and flossing are essential, but they can’t fully correct a bacterial imbalance on their own. Even mouthwash, which may kill bacteria, can wipe out both the bad and the good.

Dental probiotics, on the other hand, actively rebuild and strengthen the good bacteria in your mouth, creating an environment where harmful bacteria struggle to survive.

The result? Fresher breath, healthier gums, and long-term protection against dental issues.

I had never heard of these before so wasn’t sure about buying them. So glad I did. Pleasant taste lasts around three minutes then they dissolve in your mouth. Breath remains minty and no morning breath. Highly recommend

I'm a great fan of this product and have been using it practically since it was first advertised. My dental health has been improved, especially gum health, and it's so nice to wake up in the morning without a bad taste in my mouth. If I miss taking one for any reason, I really notice the difference. It would be really good if the tablets came in smaller bottles to save on plastic waste.

    I have a systemic issue (MCAS) which affects the balance of flora (mouth, GIT etc). I have to avoid probiotics that are histamine inducing. Mouthgenics happens to be the least triggering formula that I have come across.

    I have bought 4 x 30 of your supplements thus far and once, when I forget to take my nightly dose, there was a noticeable difference in oral ‘sweetness’ the following morning.

    Your website, payment system and customer care has been seamless and efficient too.

    I feel very grateful.

    Love these oral probiotics. After a bad Covid infection I got periodontal disease and wanted to maintain my gum health as I’ve been paying for expensive gum treatment since. I’ve tried other brands Blis K12 but been really disappointed with the taste. I love the taste and the fact they are evidence based . My daughter is also now a convert.

    Louise (verified owner) –

    I bought these to protect the gum around my wisdom tooth which sometimes gets swollen as I didn’t want to have to take antibiotics. They helped clear up the swelling very quickly.
    Today, I just came back from the dental hygienist- my 6 monthly visit- and she said there was a definite improvement since the last visit. Much less plaque, and I told her I had had a lot less bleeding gums too. They also bled far less than they normally do after the hygienist had been poking and scraping and doing AirFlow for half an hour. Very pleased and will definitely be continuing.
    I also want to commend the very friendly and helpful customer service team. I contacted them when one of my bottles arrived not properly sealed and they sent me two in replacement, which arrived very quickly.

    I bought these for my husband who suffers from gum disease, loose teeth and bad breath. He was in a cycle of being afraid to brush his teeth as the gums bled so much then finding loose teeth and having bad breath. After years of using corsodyl toothpaste and mouthwash, obliterating his oral microbiome, mouthgenics was a last effort to save his teeth.
    The dog breath was gone after one day, the bleeding is greatly reduced and he says his teeth are no longer loose. He is using his toothbrush for longer and with more confidence.
    Please develop a toothpaste and mouthwash to enable the healthy microbiome to last all day.

    Have been taking the probiotics since the start of 2024 and my dentist was very impressed with my dental hygiene on my yearly check-up, so perhaps Mouthgenics are to thank for that! They are certainly a great addition to my evening routine and I plan to take them for a long time yet. Customer service is also fantastic, they are very supportive and very receptive to any queries I have.

    I’m taking it just before bed, and it’s definitely doing its job.
    It taste, a bit too sweet for me, as I would prefer to be more neutral, but of course everyone have a different taste buds and preferences.
    Personally, I think, its the best product on UK market right now, tackling bad breath and oral health problems.

    It is easy to find solutions to mask bad breath but only for short periods. I did not realise that there are separate probiotics for the mouth and stomach. To have a British product which includes all they key ingredients is the winner. BLIS K12 being one of them. I decided to take one tablet at night time just before going to sleep, and one in the morning. I have only taken 2 tablets and noticed more saliva thus helping to maintain a healthier mouth. I am hoping with ongoing use the benefit of all the active ingredients working collectively will reap the benefits of fresh breath. Initially after 24 hours I am happy with the results so far which will vary from person to person. The product is packaged well and the tablet dissolves nicely on the tongue.

Some of The Best Probiotic Strains for Bad Breath & Gum Disease with Research Studies

BLIS K12: Published in the National Library of Medicine: study found 23 subjects suffering with halitosis were put through 3 days of testing with the K12 strain. After a week, the subjects’ volatile sulphur compound – the unpleasant bad breath smell – showed a reduction of 85%.

Lactobacillus Reuteri: Published in Science Direct, 20 participants with pathologic halitosis tested for 2 weeks. They found a reduction in gum bleeding upon probing, reduced gum pocket depths and decreasing the bad breath pathogens.

Lactobacillus Brevis: Published in the University of L’Aquila, Italy, found that taking a supplement with Lactobacillus brevis helped treat gum disease and gum inflammation.

Lactobacillus brevis may also help protect teeth by making them more resistant to enamel demineralisation. It has also shown potential for aiding in the remineralisation process, helping to restore minerals to the enamel, which can prevent early tooth decay.

Lactobacillus Paracasei: Cited in Dentistry Journal, a study on 122 children over a period of 12 months found L. Paracasei had a significant reduction of cavity causing bacterium notorious for tooth decay and plaque.

FAQs

Most frequent questions and answers

The most effective method of taking our Dental Probiotics product is to take the chewable tablet before going to bed, after brushing your teeth. Ensure they’re allowed to dissolve slowly in your mouth. Move it around in your mouth without chewing, allowing the beneficial bacteria to adhere to your tooth surfaces and gums for maximum effectiveness. It should take around 3-5mins to get really small before it can be bitten and swallowed.

This varies by product and by person. Your oral care routine, including habits like flossing, as well as factors such as dry mouth or saliva flow, can affect how quickly you notice a difference. Most people may see results within a few days or a few weeks while others may take several months to see a noticeable difference.

When choosing a dental probiotic supplement, it’s important to consider the strain count and CFU count. A good dental probiotic supplement should contain at least 6-8 strains of beneficial bacteria with a minimum of 6 billion CFU per serving. This will ensure that you are getting a strong and effective probiotic supplement for oral health.

We recommend to also look for complementary ingredients aimed at fresh breath or gum support, such as Vitamin D, Zinc, Inulin and Xylitol. These ingredients can help to reduce plaque buildup, support healthy gums and tooth enamel, and protect against bacteria that cause cavities.

Alongside probiotics, keeping the mouth clean with flossing or even a water flosser can support the oral flora.

If you have ongoing bleeding, soreness, or concerns such as receding gums, it’s best to speak to your dentist. Food supplements should not replace a varied, balanced diet or a healthy lifestyle.

No – our Dental Probiotics product does not need to be refrigerated and can be stored in a cool, dry place.

Unlike products that mainly freshen breath or mask odour, dental probiotics are designed to support a balanced oral microbiome by helping beneficial bacteria outcompete unwanted bacteria. That makes them a useful addition to daily hygiene rather than a replacement for other oral care steps.
