Are there any Ph tablets that are effective at neutralizing the acid that isn’t toothpaste? I’ve only recently learned you aren’t supposed to rinse your mouth after brushing!

You could just eat a spoonful of baking soda.

I put baking soda in my drinking water, as mentioned at https://news.ycombinator.com/item?id=27329115 - typically 1 teaspoon per liter

> (it doesn’t hurt!) It doesn't hurt for you . Some people, including myself, have had root canals that have almost caused worse pain than when I was in the ICU.

That's the parent's point: the tools and methods have changed so that now it no longer hurts.

This was 5 years ago. We're all different. Some people respond poorly to root canals, some feel moderate pain, some feel absolutely no pain.

And to be clear, the pain has been after my root canal, not during (even though ostensibly, the nerve is gone). My worst root canal was infected, but the endodontist claims that it usually doesn't cause that much pain (perhaps, but not for some people).

My mother and uncle have had the same issues. My father has never had issues.

Crooked dentists? Is this some sort of conspiracy theory? Dentists are medical professionals, who have been needed since the dark ages, and nowadays have very complex equipment and technology to ensure the best long-term and life-like suitable treatments for people. What are you on about?

To be fair, dentists do engage in what really looks like price fixing (at least where I am, and to an outside eye). Every dentist here charges the exact same amount, regardless of whether they’re in the middle of a high-income metropolitan area or in bumkinville. Also every once in a while you see some real horror stories of dentists doing unnecessary procedures on sedated patients, and although the extreme cases are…

In the USA? If so, that's probably moreso a result of the reimbursement structures imposed by dental insurance companies, rather than active collusion among dentists.

How does this compare with Sensodyne Repair and Protect? That product uses Novamin and effective rebuilds enamel, also offering whitening, reduced sensitivity, etc.

Repair is not rebuilding. “Repair” toothpaste chemically strengthens existing enamel.

Fluoride strengthens enamel. Novamin remineralizes enamel. It "rebuilds" it. How Sensodyne markets it is largely irrelevant.

Indeed, this product targets sensitivity which is exactly what Novamin does (by remineralizing those tiny holes permanently, versus traditional sensitivity products that simply "clog" them temporarily).

Note that Novamin-containing Sensodyne is an overseas thing that you have to import. For whatever reason they didn't seek FDA approval in the US so the product there is sans it.

Weird teeth-cleaning trick that I discovered from suffering from interstitial cystitis / painful bladder syndrome (IC / BPS): toss a bit of baking soda in your water, such as 1 teaspoon per liter. It makes it alkaline. My teeth got whiter and felt better (less of a film feeling). Baking soda is used as a cooking ingredient and shouldn't be too risky, but don't go overboard... bit of discussion on the IC / BPS aspect…

Urine alkalinization will also slow down your kidney's excretion of alkaline drugs and their metabolites. And speed up excretion of acidic drugs.

And yes, you definitely don't want to overdo it:

sugar doesn't cause cavities, acids do. some bacteria which is not uniformly present in people eats carbs and deposits acids. this is covered in great detail ina good book, "kiss your dentist goodbye" that i just read. ive seen improvements in my awful teeth after giving the free regimen a try

Wait, what? Where did you learn that?

Not really. Plaque removal has to be the #1 thing done at a dentist's office. I've had one cavity filled in the last 15 years, and the rest of the visits have been cleanings (ie. plaque removal). Plus, it really doesn't matter how well you brush and floss. There's always something for the hygienist to remove. Which, I can only assume prevents this lozenge from actually doing anything.

Perhaps in the future there will be a layer added to this pill that first dissolves the plaque.

That itself could be a standalone product -- I'd expect lots of people would prefer sucking a lozenge over daily toothbrushing

A teaspoon of baking soda dissolved in a glass of cold water is also the absolute best, instant cure for heartburn. TUMS could never.

> In addition, the researchers are investigating a gel or solution with the engineered peptide to treat hypersensitive teeth. This problem results from weakness in the enamel that makes the underlying dentin and nerves more vulnerable to heat or cold. Most common products currently on the market can put a layer of organic material on the tooth and numb nerve endings with potassium nitrate, but the relief is only temp…

Have you tried a toothpaste with Stannous Fluoride? Potassium nitrate never helped me any, but stannous fluoride has helped with my tooth sensitivity.

Doesn't pretty much all toothpaste have that? Unless its kid's toothpaste or something specifically for people who are avoiding flouride.
