Dentists have really helpful fluoride toothpaste for stronger cavity-resistant tooth for many years.1 It’s nonetheless thought of the “gold commonplace” in dental colleges, regardless of its security issues.
However there’s a brand new ingredient on the town confirmed to be simply as efficient as fluoride and utterly non-toxic.
It’s referred to as hydroxyapatite. Hydroxyapatite toothpaste has changed fluoride toothpaste as what I like to recommend to all of my sufferers. However what’s hydroxyapatite toothpaste?
On this weblog publish, we’ll study hydroxyapatite and try how fluoride compares with it.
How Does Fluoride Toothpaste Work?
Your tooth have an outer masking referred to as enamel that’s made up of calcium and phosphate. Your saliva additionally comprises calcium and phosphate that continuously bathe your tooth. These minerals maintain your tooth sturdy.
Micro organism present in cavities can break down meals particles and create an acidic surroundings in your mouth. This acidic surroundings is harsh and might strip away these useful minerals from the surfaces of your tooth. This course of is named demineralization.
The fluoride in fluoridated toothpaste works by:
- Teaming up with the calcium and phosphate in your saliva and tooth to type a compound referred to as fluorapatite. This compound appears to be like like a crystal lattice (apatite crystal lattice).
- Masking demineralized enamel with the extra acid-resistant fluorapatite. This remineralizes the tooth, restores their energy, and protects it from additional injury by acid.
How Does Hydroxyapatite Toothpaste Work?
Hydroxyapatite is a type of calcium that makes up 97% of your tooth enamel and almost 70% of the dentin of your tooth.
The remainder of your enamel is definitely composed of water, collagen, and different proteins.
Hydroxyapatite is absorbed by the tooth and fills the enamel fissures brought on by demineralization.
Essentially the most extensively studied sort of hydroxyapatite is nano-hydroxyapatite. Toothpaste that comprises nano-hydroxyapatite has particle sizes between 20-80 nanometers (nm). Due to its small measurement, it could possibly insert into actually small areas, which ends up in higher advantages.
Not like fluoride, hydroxyapatite works by:
- Remineralizing enamel from inside, reaching the innermost a part of a dental cavity
- Binding to plaque and dangerous micro organism in our mouth
How does Hydroxyapatite Examine to Fluoride in Efficacy?
In the case of which toothpaste is extra environment friendly, there’s actually no distinction between hydroxyapatite and fluoride toothpastes.
One research in contrast 10% hydroxyapatite with 500 ppm F− (amine fluoride), which dentists sometimes prescribe.2 The researchers found that the ten% hydroxyapatite labored simply in addition to 500ppm F− for remineralization and lesion depth (LD) discount.
The conclusion of the research was that hydroxyapatite toothpaste is the same as fluoride toothpaste relating to efficacy.
Advantages of Hydroxyapatite over Fluoride Toothpastes
Each fluoride and hydroxyapatite can remineralize tooth construction, however right here’s why I want to suggest hydroxyapatite over fluoride:
- Oral microbiome pleasant: Though each have antibacterial properties, fluoride kills decay-causing micro organism and a few good micro organism. Alternatively, hydroxyapatite doesn’t kill the micro organism. It prevents dangerous micro organism from attaching to the enamel.3
- Fortifies enamel: Hydroxyapatite can improve the microhardness of enamel.4 The coating of hydroxyapatite reinforces the tooth higher than the fluorapatite coating.
- Non-toxic: Hydroxyapatite is biomimetic.5 There aren’t any negative effects with hydroxyapatite—the truth is, it’s secure sufficient to swallow all the tube of toothpaste! With fluoride, then again, there’s a poison management label on the tube, and overexposure causes dental and skeletal fluorosis.
- Child-friendly: At an early age, youngsters don’t have full management over swallowing and might ingest giant quantities of toothpaste.6 When this occurs, the fluoride in toothpaste can get absorbed into the bloodstream and trigger dental fluorosis (a change within the look of tooth enamel). Toothpaste that comprises hydroxyapatite reduces the danger of fluorosis.
- Whitens: Hydroxyapatite toothpaste has been proven to lighten the shade of the tooth with out the assistance of any further abrasives or whitening brokers.7
Is Fluorapatite Stronger than Hydroxyapatite?
Fluorapatite is much less soluble than hydroxyapatite. Which means that in acidic circumstances, fluorapatite is stronger and extra immune to demineralization.
Nevertheless, this doesn’t imply that fluorapatite toothpaste is best than hydroxyapatite toothpaste. The truth is, research present that hydroxyapatite toothpaste is simply nearly as good as fluorapatite toothpaste, with an additional benefit — it helps with dental hypersensitivity.8
Ought to I Swap to Hydroxyapatite Toothpaste?
To me, it is a no-brainer. When you have a greater various to fluoride toothpaste and it’s non-toxic, why wouldn’t you?
To most dentists, it is a no-brainer as nicely—nonetheless, fluoride remains to be taught because the “gold commonplace” in dental colleges, and there are nonetheless some dentists on the market who is likely to be leery of hydroxyapatite. If that is your dentist, ship them the analysis!
I like to recommend everybody speak to their dentist about switching to a hydroxyapatite toothpaste, particularly the next classes of individuals:
- Pregnant ladies
- Individuals who dwell in areas with fluoridated water provide
- Infants and kids, particularly if they’re beneath the age of six.
- Folks with delicate tooth, as hydroxyapatite treats the basis reason for sensitivity.9
Which Toothpaste Manufacturers Include Hydroxyapatite?
There are two manufacturers of hydroxyapatite toothpaste manufacturers I like to recommend to readers as a result of I exploit them myself and so they even have an applicable focus of hydroxyapatite to be efficacious. There are numerous hydroxyapatite toothpastes on the market, sadly, that don’t include sufficient of the ingredient to have an impact—in case you’re undecided, e-mail the corporate and ask for the focus. It ought to be 15% or extra.

Backside line
The most important benefit of utilizing toothpaste with hydroxyapatite is that it remineralizes your tooth with none negative effects, in contrast to fluoride that’s poisonous in giant portions.
Hydroxyapatite is of course current inside our physique and constitutes most of our enamel.
Each fluoride and hydroxyapatite are scientifically confirmed to reverse dental decay—why not select the much less poisonous one?
