[Home](https://oralbench.com/) 2. [Guides](https://oralbench.com/guides) 3. Supplements for bad breath: mint, clove and a few probiotics Many tooth supplements promise fresh breath somewhere on the page. We checked what each label or sales page actually puts toward it, and set that next to what MedlinePlus, from the National Library of Medicine, says causes the smell. By **[OralBench editorial team](https://oralbench.com/about)** Updated October 27, 2026 ![A man in an office checking his breath behind his hand](https://oralbench.com/img/guia-bad-breath-supplements-768.webp?v=008e9b1161) Short answer Most of what these supplements put toward fresh breath is flavor: peppermint, wild mint or clove. MedlinePlus, from the National Library of Medicine, says "Bacteria that build up in your mouth and between your teeth produce the bad odor", and it credits brushing and flossing regularly with helping fight bad breath, while mints and gum "may make your breath fresher." No public health source we read covers probiotics for bad breath. GumAktiv is the one oral probiotic here whose label gives a single bacterium its own amount (20 mg of Streptococcus salivarius), and its page shows no breath data.

[How we choose and how we earn](https://oralbench.com/affiliate-disclosure) ## Products on this site that contain it - ### GumAktiv **Best for:** people who want an oral probiotic with Streptococcus salivarius in a stated amount #### Pros - 20 mg of Streptococcus salivarius on the label - Also names L. paracasei, L. reuteri and B. lactis BL-04 - A tablet you let dissolve in your mouth #### Cons - The label doesn't name the S. salivarius strain - No breath data on the page - Peppermint oil adds flavor, so fresher breath right after isn't proof of anything **Verdict** The only oral probiotic on this site that tells you how much Streptococcus salivarius is in each tablet. No public health source we read links probiotics to breath, so brushing and flossing stay the main plan.

Mouth & gums ### [Bad breath: the usual causes, the unusual ones, and what to do](https://oralbench.com/bad-breath) Halitosis is the medical name for bad breath. ## What each supplement puts toward fresh breath Product Mint, clove or other named ingredient Amount What the page says about it GumAktiv Streptococcus salivarius (a probiotic); peppermint oil 20 mg; not stated Nothing about breath for S. salivarius, which the page never mentions DentaVive Streptococcus salivarius K12 (a probiotic) Not disclosed Calls the strain "The Breath Guardian" DentaBiome Lactobacillus salivarius, which the page calls a "postbiotic strain" Not disclosed "Reduces volatile sulfur compounds (bad breath)" PurDentix Four probiotic strains in one blend, L. salivarius among them; peppermint leaf 40 mg for the blend, none per strain; not stated "Freshens Breath at the Source" ProDentim Peppermint Not disclosed (blend) Flavor, listed as a natural ingredient BioDentex Peppermint; stevia Not disclosed "Helps maintain fresh breath"; "Supports clean teeth and fresh breath" FortBite Clove and peppermint (brushed on) Not disclosed "Help maintain a fresh breath" Power Bite Wild mint; clove oil Not disclosed Flavor and aroma Dentitox Pro Peppermint oil Not stated Says it supports your teeth, "keeping them strong and your breath fresh" Oradentum Licorice root; cinnamon bark extract 50 mg each "Promote fresh breath and maintain oral cleanliness naturally" DentiCore Sodium copper chlorophyllin; peppermint leaf extract Part of a 120 mg blend; not stated Its pitch is about gums and airways OxyDental Sodium copper chlorophyllin; peppermint leaf extract Part of a 120 mg blend; not stated "eliminate foul odors at their source"; "freshen breath" DentaSmile Pro None named Not applicable The label: "Promotes whiter teeth, healthier gums and fresher breath" DentiVive None named Not applicable "A formula for healthy teeth and fresh breath" From each official page and label, read on September 25, 2026 (OxyDental and DentaSmile Pro on September 27, 2026; DentaBiome, DentaVive, Dentitox Pro, Oradentum and PurDentix on October 27, 2026). BioDentex, DentaBiome, DentaVive, DentiVive, FortBite, Power Bite and ProDentim show no supplement facts panel, so their rows come from the sales page. Each product has its own review on this site. ## How to read "fresh breath" on a label ### Freshening is a different claim MedlinePlus says mints and gum "may make your breath fresher," and that brushing and flossing regularly "help fight bad breath." Most of these labels make the first kind of promise. ### Look for a stated amount GumAktiv puts a number next to the ingredient it's built around, and Oradentum's label lists 50 mg each of the licorice root and cinnamon its page ties to fresh breath, on a panel that matches a blood sugar formula. Everything else is a name with no dose. ### Ask where the claim comes from None of these pages shows a breath test of its own product. A claim with nothing behind it is marketing. ## What helps, and when to get checked MedlinePlus keeps it short: "Having good dental habits, like brushing and flossing regularly, help fight bad breath." NIDCR's gum disease page spells out the routine: "Brushing your teeth twice a day with a fluoride toothpaste," flossing regularly, and seeing the dentist for check-ups and professional cleanings. If your mouth feels dry, NIDCR suggests drinking plenty of water and chewing sugarless gum or sucking on sugarless hard candy "to stimulate saliva flow." And if you think you have dry mouth, it says to "see your dentist or doctor to find out why your mouth is dry." Bad breath that sticks around is a reason to book a dental visit, since NIDCR counts it among the signs of gum disease. Since MedlinePlus notes that some diseases and medicines cause their own breath odor, it's worth raising with your doctor too if the dentist finds nothing in your mouth. ## Frequently asked questions **Do probiotics help bad breath?** No public health source we read covers probiotics for bad breath; none of these products shows breath data. **What is the best supplement for bad breath?** There isn't one we can point to with evidence behind it. If you want a probiotic anyway, GumAktiv at least tells you how much S. salivarius you're getting. **Why does my breath still smell after mints?** Mints "may make your breath fresher," as MedlinePlus puts it, but it traces the odor to "Bacteria that build up in your mouth and between your teeth." What it credits against bad breath is brushing and flossing regularly. **When should I see a dentist about bad breath?** When it doesn't go away with good brushing and flossing. NIDCR lists persistent bad breath as a symptom of gum disease, which a dentist or dental hygienist checks for. ## Sources Public pages from U.S. government health agencies that this page relies on.
