ProvaDent

Xylitol-first: organic xylitol, cranberry, purple carrot and 4 unnamed strains. Two tablets a day.

ProvaDent official site

ProDentim vs ProvaDent is a fair question: both are chewable oral probiotics sold online, both cost the same and both come with a 60-day guarantee. But they are built on different ideas. We wrote a full review of each (ProDentim and ProvaDent). This page puts the facts side by side, checked on both official sites and labels in October 2026, so you can decide which one, if either, fits you.

What is different inside

ProDentim: built around named probiotic strains

According to the manufacturer, each ProDentim tablet holds 3.5 billion bacteria from three strains, plus inulin (a plant fiber), malic acid, tricalcium phosphate and peppermint. The strain that matters most is Lactobacillus reuteri: several small trials of specific L. reuteri strains have looked at gum inflammation, with some encouraging results. The catch is that results depend on the exact strain and dose, and ProDentim does not give the amount of each strain.

ProvaDent: built around xylitol

ProvaDent leads with organic xylitol, a sweetener that the bacteria behind cavities cannot ferment. A large Cochrane review found the evidence for xylitol preventing cavities is real but low quality, and studies usually used several grams a day. ProvaDent does not say how much xylitol each tablet contains. It adds cranberry extract (early lab research on bacteria sticking to teeth), purple carrot powder (little direct research), a proprietary "BioFresh Clean Complex" whose contents are not disclosed, and four probiotic strains without names.

What they have in common

Both are dietary supplements, not treatments. Neither replaces brushing, flossing or the dentist, and neither finished product has a published clinical trial. For what the research shows goal by goal, read our guide to oral probiotics. For a neutral overview, see the NIH Office of Dietary Supplements probiotics fact sheet.

Price and cost per day

Both are sold only through their official websites, with orders processed by ClickBank. When we checked in October 2026, both offered the same three packages. ProvaDent has twice as many tablets per bottle, but you take two a day, so each bottle of either lasts 30 days and the cost per day is identical:

The bonuses are e-books with home oral care tips, not extra product. Offers change often, so confirm the price on the order page. If you are trying an oral probiotic for the first time, a smaller package keeps less money tied up while you decide, and both come with a 60-day money-back guarantee counted from the order date.

Safety: the xylitol question

Probiotics are generally well tolerated by healthy adults; mild digestive changes are the most common effect. Xylitol is safe for people in normal amounts, but large amounts can cause gas or loose stools. The one clear safety difference is pets: xylitol is highly toxic to dogs, even in small amounts (FDA explanation). If you have a dog and cannot keep the bottle out of reach, ProvaDent is the riskier choice.

For either product: people with a weakened immune system, serious illness, pregnancy, or who take prescription medication should talk to a doctor first, and children should not take them without a pediatrician's approval.

What other comparisons get wrong

Most pages ranking for "ProDentim vs ProvaDent" are sales copy hosted on unrelated websites, and they contradict each other. Here is what we found, compared with what the official sites and labels say:

• "ProvaDent is a liquid" or "a capsule you swallow". The label says chewable tablets, 60 per bottle. One section of the official site mentions a "capsule", but the rest of the site and the label describe a chewable.
• Specific ProvaDent strain names. Some pages list strains such as Streptococcus salivarius or Bacillus coagulans. The official site only says "4 strains of probiotics" and names none, so those lists are guesses.
• A 30-day or 90-day ProvaDent guarantee. The official site states 60 days, the same as ProDentim.
• "ProvaDent is cheaper". In October 2026 both had identical package prices and the same cost per day.
• A clear "winner". Without a clinical trial of either product, any page declaring a proven winner is going beyond the evidence.

Which one to choose

Skip both if you have pain, bleeding gums or a loose tooth: see a dentist first. And whichever you pick, the basics matter far more: brush twice a day with fluoride toothpaste, clean between your teeth daily, cut down on sugary snacks and keep your checkups. The American Dental Association's MouthHealthy site is a good free reference.
