Fluoridex Sensitivity Relief is a prescription-strength toothpaste made by Den-Mat. It combines 1.1% sodium fluoride with 5% potassium nitrate in a clean mint paste. Dentists often recommend it for sensitive teeth and cavity-prone mouths.
Buyers rate it highly. Dental retailers show scores between 4.7 and 4.96 out of 5, though many ratings come from the stores that sell it. Drugs.com shows a lower 7.3 out of 10 from only four reviews. Sample sizes matter here.
So is it worth the higher price and the prescription step? This review covers the formula, how it works, what users say, and what it costs. Our team at Optimal Weight Plan kept the focus on evidence, not sales copy.
What Is Fluoridex Sensitivity Relief Toothpaste?
Fluoridex Sensitivity Relief is a prescription-strength anticavity toothpaste designed to calm sensitive teeth while strengthening enamel. The 4 oz (112 g) tube carries an Rx Only label. Sellers describe it as a clean mint formula.
The brand sits in the Den-Mat professional line. Retailers say it was the first professional-strength fluoride toothpaste to pair this much potassium nitrate with high fluoride. That is the seller's claim, not an independent ranking.
What Is in Fluoridex Sensitivity Relief?
Two active ingredients drive the formula. Sodium fluoride at 1.1% (5000 ppm) fights decay, and potassium nitrate at 5% soothes sensitivity. Ordinary store toothpaste holds about 0.32% sodium fluoride (1450 ppm), so this paste carries roughly three to four times more.
The standard version contains sodium lauryl sulfate (SLS). An SLS-free version exists for people who react to it. Check the box for your exact variant before you buy.
Key Facts:
- 1.1% neutral sodium fluoride (5000 ppm)
- 5% potassium nitrate
- Clean mint flavor
- Standard and SLS-free versions
- 4 oz (112 g) tube
How Does Fluoridex Sensitivity Relief Work?
Fluoridex Sensitivity Relief works in two ways: potassium nitrate calms tooth nerves, and high-dose fluoride rebuilds enamel. Potassium nitrate settles the nerve endings inside the tiny channels of the dentin (dentinal tubules). Fluoride strengthens the surface above them.
Retailers say most users notice less sensitivity within about two weeks of twice-daily brushing. Why the wait? Potassium nitrate builds its effect over repeated use. It does not numb on the first brush.
Use a pea-sized amount in place of regular toothpaste, as your dentist directs. Then spit and skip food and drink for 30 minutes so the fluoride can settle onto the teeth.
How to Use It:
- Squeeze a pea-sized amount onto the brush.
- Brush all tooth surfaces as your dentist directs.
- Spit out the paste and avoid swallowing it.
- Wait 30 minutes before eating or drinking.
Does Fluoridex Sensitivity Relief Actually Reduce Sensitivity?
Yes, for most reviewers. Users describe noticeably calmer teeth compared with other sensitive toothpastes they tried. One buyer says it works better than any other sensitivity paste she has used. Another says it ended the sores in her mouth.
Results still vary. Sensitivity has many causes, including gum recession and worn enamel. A paste cannot fix a cracked tooth or a deep cavity, so see your dentist if pain persists.
What Are the Benefits of Fluoridex Sensitivity Relief?
Fluoridex Sensitivity Relief offers sensitivity relief, cavity protection, and enamel support in a single daily paste. You skip the extra step of layering a separate sensitivity product over a fluoride product. One tube does both jobs.
Sellers also point to use after whitening, when teeth often feel tender. Others recommend it for people with gum recession, worn dentin, or low fluoride in their drinking water. Those are seller recommendations, not trial results.
Main Benefits:
- Calms sensitive teeth with 5% potassium nitrate
- Helps prevent cavities with 5000 ppm fluoride
- Supports enamel remineralization
- Offers relief after whitening treatments
- SLS-free option available
Who Benefits Most From Fluoridex Sensitivity Relief?
People with elevated cavity risk and sensitive teeth gain the most from a prescription-strength paste. Dentists often suggest it for patients with exposed dentin or recent whitening. Patients with dry mouth after medical treatment are another group dentists consider.
A dentist decides if the dose fits you. Higher fluoride is a targeted tool, not an upgrade for every mouth.
What Do Fluoridex Sensitivity Relief Reviews Say?
Reviews are strongly positive across dental retailers, with ratings between 4.7 and 4.96 out of 5. DentalStores.com shows 4.96 from 228 reviews. DentalHealth.com shows 4.70 from 459 reviews, and its SLS-free listing shows 4.80 from 116. Benco shows a perfect 5.0, but from only four ratings.
Independent sources are thinner. Drugs.com lists a 7.3 out of 10 average from four reviews, with 50% reporting a positive experience. Small samples swing wildly, so weigh them lightly.

What Do Happy Users Say?
Happy users praise the clean taste and the strong sensitivity relief. Several mention that their dentist recommended it. One calls it the best toothpaste she has tried for sensitive teeth. Another says it works better than other sensitive pastes.
What Do Unhappy Users Say?
Complaints are rare in the text we reviewed, but the Drugs.com page shows that not everyone had a good result. Only half of its four reviewers reported a positive experience. The reasons were not detailed in the snippets we could access.
The price and the prescription requirement are the practical hurdles. Both come up in the cost section below.
How Does Fluoridex Compare With Clinpro 5000 and PreviDent 5000?
All three are 1.1% sodium fluoride (5000 ppm) prescription pastes. Fluoridex stands out for its sensitivity and whitening variants. Clinpro 5000 is a straightforward fluoride paste without sensitivity or whitening versions. PreviDent 5000 comes from Colgate and has Booster Plus, Sensitive, and Dry Mouth versions.
Flavor can decide it too. Clinpro comes in Mint and Bubble Gum. Fluoridex is mint only, which matters if mint bothers you.
Side-by-Side:
| Product | Fluoride | Variants |
|---|---|---|
| Fluoridex | 1.1% (5000 ppm) | Sensitivity, Sensitivity SLS-free, Whitening |
| Clinpro 5000 | 1.1% (5000 ppm) | Mint, Bubble Gum |
| PreviDent 5000 | 1.1% (5000 ppm) | Booster Plus, Sensitive, Dry Mouth |
Is Fluoridex Sensitivity Relief Safe?
Yes, when used as your dentist directs. It is a prescription product, so a dental professional should confirm it fits your risk level. The dose is far higher than regular toothpaste. Spit it out and do not swallow it.
We found no safety trial specific to this product in our research. The cautions below are general guidance for high-fluoride pastes, not claims from the maker.
Who Should Avoid Fluoridex Sensitivity Relief?
Young children and anyone who tends to swallow toothpaste should avoid it unless a dentist says otherwise. Swallowing high-fluoride paste is the main risk. Keep the tube out of reach of kids.
Ask Before Using If:
- You are pregnant or nursing
- You are giving it to a child
- You react to sodium lauryl sulfate (choose the SLS-free version)
- Your tooth pain is sudden, severe, or one-sided
How Much Does Fluoridex Sensitivity Relief Cost?

Where Can You Buy Fluoridex Sensitivity Relief?
You can buy it from dental suppliers and online dental shops, and your dentist may sell it directly. Because it is prescription strength, some sellers run a short eligibility check first. Buy from a reputable dental source.
Is Fluoridex Sensitivity Relief Worth the Price?
Yes, if you have sensitivity and a real cavity risk. A tube costs less than one dental filling co-pay at most sellers. The best price is often at a dental supplier.
Skip it if you have mild sensitivity only. A standard desensitizing paste may be enough, and your dentist can tell you.
