That stuff has to be extremely strong, to withstand the constant pressure on it. What is it, and why isn’t it sold commercially for other purposes? Or is it?
[My father had a problem with a crown constantly falling off, and finally went to a different dentist who got it permanently attatched. She told him the first dentist was using a lesser type of cement and she used the real good stuff. But she said the reason most dentists don’t use what she used was that it would make removing the crown, if necessary for whatever reason, virtually impossible and it would have to be cut off in pieces.]
I’ve been a dentist over 30 years. I use 3M glass ionomer luting cement. Haven’t read the package in years but I don’t think it is Rx only so I imagine one could buy it online. Zinc oxide eugenol is now mainly used as a temporary cement or when one needs a sedative effect.
Maybe someone can finally answer my question! I have at home some dental cement that appears to be about 40–50 years old. It is labelled “Dralalith 60 Füllungs-Porzellan”, “Made in Western-Germany by DRALA Dental-KG, Hamburg”. My question is, what is it? (There is a white powder and a liquid component.)
Some time ago, my dentist and I discussed crown removal on some future work I anticipated and I asked him how the old crown is removed. He said that normally he avoids attempts to force it away from the remaining tooth, unless it’s loose, and simply drills it off as a matter of routine.
My guess is that the stuff at Home Depot is just as good as dental cement, and cheaper, so there’s no market for it. So why don’t dentists use the Home Depot stuff? Because it’s going in people’s mouths, so they need the expensive stuff that has been verified as safe for human mouths.
Again, this was only my guess. But it is very much in line with what I often tell my kids: Most of your questions can be answered with the single word, “marketing”.
I can’t think of anything in HD which is applied to such a small area and can then withstand the strong pressure that people subject their teeth to, constantly and over such a long period of time. Perhaps I’m wrong. But I would give dental cement a shot.
