not baking soda, it was the bleach.
And it’s NOT BS. I live with my ruined teeth.

Ceramic restorations do not have "enamel" surfaces. Only natural teeth have enamel surfaces and a 20 to 1 of 7% original Clorox Dakin's solution will not even touch that enamel much less any Ceramic, which is a hard, non-reactive, glassy substance which is used in CHEMICAL LABS to contain many very reactive chemicals including strong acids and bases. You could have used the Clorox full strength from the bottle on a denture and probably not harmed it, but I would not advise it.

Using an even STRONGER household bleach (9 to 1) solution is often recommended to disinfect dentures regardless of materials they are made of to kill any residual oral yeast infections.

Your stomach acid can be as high as Ph 1.5 and your dental restoration is designed to withstand you vomiting that level of acid and not being discolored or being damaged in situ by that level of acid being poured over it. I assure you the materials your restoration was made out of, unless your dentist was extremely incompetent, were well capable of withstanding a short bath of very dilute Sodium Hypochlorite. . . And in fact we're probably bathed in a stronger solution of it when they were manufactured to clean and disinfect them.

While full strength Dakin's Solution, a base, has a Ph of 10, according to manufacturers of commercial versions of it the solution does not even require a Materials Data Satety Sheet it is so innocuous.

"Dakin's Solution® is not considered a hazardous substance1; therefore a Material Safety Data Sheet is neither required nor available.
Please accept this information sheet as a substitute.

The Dakin's solution recommended in this article is only slightly stronger than the water you would encounter in a public swimming pool or a spa and in fact degrades within minutes to salt water.

Starting with the new 7% solution of NaOCl in water, the Clorox formulation, diluted by 24 water added to 1 Clorox, the resulting NaOCl is only a ~0.3% solution. That is extremely weak. . . It's even recommended as a mouthwash regardless of what appliances you have in your mouth.

Note this PDF on how to make Dakin's Solution from Ohio State University Medical Center, (it uses the old Clorox concentration of 5.25%), and mentions the use as a mouthwash.

Dental ceramics are not easily affected by chemicals, Right-wing Librarian. In fact, just silicate ceramics, the lowest and cheapest level ceramics that might be used, are really hard to chemically change:

Ceramics generally have good chemical resistance to weak acids and weak bases. However, very strong acids or strong bases tend to produce ion exchange reactions and dissolve the structures. HF is commonly used to intentionally etch ceramic surfaces composed of silicates. It is the F- ion that causes the actual damage. In dentistry, most 2-phase silica-based restorations are treated with 10% HF solutions to etch them. This produces different dissolution that creates micromechanical relief prior to micromechanical bonding.

HF is HydroFluoric Acid, the strongest acid known. We use it it to etch the surfaces of the ceramics so they can be chemically glued to each other or to the tooth surfaces. It is FAR stronger than the weak acids or bases you are claiming damaged your ceramic restorations. Most modern ceramic restorations use sapphire or alumina composite ceramics which are even more impervious to chemical reaction that these more silicate and cheaper versions.

So, I repeat, your claim is BS.
