Sensodyne Repair Protect Toothpaste with Fluoride 70 gm - Pack of 1

Thank you for making this product available! I live in the US, and our version of Sensodyne Repair and Protect does not contain NovaMin (bioglass). This product is shipped from the UK and DOES contain NovaMin.I didn't take good care of my teeth when I was younger, and consequently I have suffered the acid erosion that results from careless dental hygiene paired with a Pepsi addiction. There's nothing I regret more. Now my enamel is thin, and I'm left with sensitive teeth.I've been using this product for over a year, and it has absolutely helped with my sensitivity problem! I used to be very sensitive to hot and cold temperatures, and even brushing my teeth hurt in certain areas. I no longer have pain, and even ice cream is actually manageable now! However, even with the tremendous improvement with sensitivity, teeth-whitening strips still hurt. I've never been able to use them longer than a couple days, so I've stopped trying. Also, I have not experienced any noticeable whitening as a result of using this toothpaste.Besides the overall decrease in sensitivity, the toothpaste flavor tastes good, and my dentist appointments have been going well. It's too early for me to personally determine this toothpaste's effectiveness at cavity prevention. Judging from the unique way NovaMin works to remineralize your teeth, I imagine it's helping a lot!Additional information about remineralization and NovaMin:For the past 6 months, I have been using this Sensodyne toothpaste in the morning and a prescribed fluoride toothpaste at night (Colgate PreviDent 1.1% Sodium Fluoride). Both are meant to aid in the remineralization of tooth enamel. Enamel remineralization doesn't exactly "regenerate" lost enamel (it won't fill a cavity or permanently build up over your teeth), but it does strengthen the enamel that remains on your teeth by providing it with the required minerals (calcium, phosphate, and fluoride).From the studies I've read about it, NovaMin has a greater remineralization effect and results in greater surface microhardness of the enamel, compared to fluoride. The way NovaMin works is that it increases the pH of the mouth (neutralizes acidity), which creates the conditions needed for remineralization. Then, the "bioglass", which is silica (glass) that contains calcium, phosphorus, and sodium, mineralizes the enamel by bonding to the surface of your teeth.This Sensodyne toothpaste contains both NovaMin and fluoride, which sounds pretty great to me!New technologies:A startup called Auxomel has developed a prototype peptide-gel that actually does "regrow" enamel! It works by mimicking the natural protein that forms enamel, which can then be mineralized. Unfortunately, it will probably be many years before it's available.Until then, our best at-home solution appears to be bioglass technologies. There is a new type of bioglass toothpaste available elsewhere in the world (not the US) called BioMin. It is supposed to be even better than NovaMin because it works for a long time (up to 12 hours after brushing), forming a barrier over the teeth that slowly releases calcium, phosphate, and fluoride to remineralize the enamel continuously throughout the day/night. Unfortunately, I don't see BioMin here on Amazon. I'd be interested in trying it, though!Update 2021-10-25: I just read that "BioMin F" was FDA approved in the USA in Dec 2020 and is currently available by prescription. The only toothpaste I'm aware of at the moment that contains it is Dr. Collins BioMin Restore Plus toothpaste. I haven't tried it. Maybe someday it will become available without a prescription?

Purchased from and shipped to the United States.Product is the UK Sensodyne Repair and Protect (75 ml) containing BOTH NovaMin and Fluoride (as per the ingredients listed on the package). As I said, THIS IS THE ONE YOU WANT. This is also relatively cheap ($7.98/tube shipped is not cheap, but it's not ridiculous either).The US version contains stannous (tin) fluoride (you know, Fluoristan, from the '60s), which isn't bad, but it won't "repair" the teeth like Novamin is supposed to. Glaxosmithkline has no trouble overcharging for the US version, despite not containing any advanced bioglass technology. In short, the US version was engineered to drain your bank account, not to repair your tooth enamel repair. Avoid the US version like the plague.As a toothpaste, it's fairly standard. Average flavor, texture, whatever. There is a slight crunch that might be the Novamin particles, but I'm not sure how large they're supposed to be. Don't store it with the cap off or the bioglass will absorb water and become less effective.Now some background on Novamin? Keeping in mind I'm not a medical professional:For whatever reason, Novamin is not sold in the US. It has been speculated that FDA approval could not be had for "repair" toothpaste (despite the fact that the drugstore is filled with products that promise to "restore" your teeth). I believe since Glaxosmithkline purchased Novamin, no Novamin products are sold in the US (this includes all of the hippie fluoride-free toothpastes that were available).This product contains 1450 ppm fluoride (as 1.08% w/w sodium monofluorophosphate). I have found claims that the maximum ppm fluoride in the US is either 1100 or 1500 ppm. Regardless, 1450 ppm of fluoride is shown to be MORE effective than Novamin alone (http://www.ncbi.nlm.nih.gov/pubmed/20546825) at preventing demineralization of teeth. Higher ppm is even better so if you need it, ask your dentist if you can have a prescription for the 5000 ppm fluoride toothpaste.However if you don't want to or can't do that, don't need prescription-strength toothpaste, or don't want to risk being exposed to very high levels of fluoride, this product, apparently, combines both a higher-than-average level of fluoride (good) and Novamin (also good). It appears that Novamin will simultaneously whiten teeth by causing fresh hydroxyapatite (the primary mineral in tooth enamel - also happens to be white) to be formed on the tooth surface. This is in contrast to other toothpastes which remove stains with hydrogen peroxide and abrasives.With continuous use, Novamin is supposed to build up a layer of hydroxyapatite on your enamel, covering up any exposed dentin and causing sensitivity to decrease. I believe (I am neither a dentist or a materials scientist) that Novamin is more effective at -covering- exposed areas than fluoride, as it is deposited (in my understanding) as a bioglass particle which binds to teeth containing the ions necessary to form hydroxyapatite (which are then released at the tooth surface). That is, the particle creates a local covering of hydroxyapatite, as opposed to the fluoride which is kind of just floating around everywhere.The hydroxyapatite deposits are only supposed to be a few microns thick (my interpretation based on this http://www.repairandprotect.ca/pdf/NovaMin_JCD_2011_Clinical_Summaries_HR_EN.pdf), so this won't regrade your teeth and fill in potholes (go to the dentist!), but it should prevent sensitivity and protect against future damage with regular use.But again, I'm not a medical professional. This is just toothpaste, you should be okay if you use it. If you have a real problem, go to the dentist and don't try to self-treat any conditions with this stuff.
