Hi,
I've used Arm & Hammer Advance White Extreme Whitening with Baking Soda Toothpaste for a while. It's cheap. It does the job. It leaves a fresh
and clean feel in my mouth, but it has baking soda and it's possibly
more abrasive than other toothpastes.
Is it ok to brush your teeth with such an abrasive toothpaste a few
times a day or should I cycle it with a less aggressive toothpaste?

Baking soda is really not very abrasive; I just looked up the
ingredients and there are no other abrasives in it. So IF your brushing technique is good using it shouldn't be a problem.

According to the safety data sheet of a similar product the abrasive is probably "Silica, amorphous, fumed, crystalline-free". I do not think
it is as abrasive as the sand it is made from. If it were it would wear
out your enamel.
A toothpaste abrasive should wear away plaque but not tooth enamel.
I have an old bridge that originally had an acrylic tooth-like coating
which is no longer there due to brushing which wore it away. Fortunately
on the side of the mouth it is not noticeable. I used to use toothpaste
to polish an acrylic watch lens and people have used toothpaste to
polish plastic headlight lenses. It is abrasive enough to remove a
fogged layer.
Silica, amorphous, fumed, crystalline-free

It was copied from an SDS for one of their whitening toothpastes and how
it is made is described in this Wiki article:

My acrylic veneer bridge, I believe, was pre-1970.
I have two bridges over 55 years old and have been surprised how long
they have lasted.
I lost a third bridge on front teeth I mentioned here a while back
replaced by a flexible acrylic bridge and never brush it with toothpaste
as I know it is abrasive to acrylic.

silica has to be abrasive. There would be no other reason to include it.

I just wonder what makes a toothpaste abrasive. What ingredients should
I avoid? I believe silica has to be the most abrasive, correct me if I'm wrong.

I had a patient--I'm thinking in the early 2000s--this gentleman in his 80s. He'd been in a concentration camp during the war. When he was liberated, he said he'd spent a year in a Swiss hospital. They did 4
large gold/acrylic veneer bridges in each quadrant of his mouth. Now 60 years later, the acrylic was all worn; the gum had shrunken back so you
could almost put your finger under them.
One of the teeth holding one of the bridges was rotten--we replaced it.
When that was finished, I asked him about the other 3--he refused to replace them. "If I did, I'd be too beautiful," he said. "My wife would
get suspicious."

Had I known maybe 20 years ago when I got a partial that my bridges
would have held up I would have gotten implants. Now over 80, not sure
it is worth it.
I might have mentioned a friend's brother that got them about age 85 and after work fully done needed a quadruple bypass. Turns out he lived to 99.

I wouldn't rule out implants based on age alone. It becomes more
worthwhile of course if you don't function well with your partial, and
if a new partial would not be expected to improve your function.

SteveMy partial works fine except for biting into something like a apple.
The flexible acrylic is fine and better than the previous one with wires going around back teeth. Every now and then I use a little adhesive if eating a sandwich.
My brother had problems with his and got implants and now I hear one of
the implants failed and he is having extra work done.
What is known about the biochemistry of how calcium, phosphate, magnesium, fluoride are ordered to form apatite to repair tooth surface? Can it just happen randomly or might bacterial colonies of some types help as they develop layers on the toothsurface? Though I guess the first layer to develop after abrasive brushing would contain the acid forming Strep mutans?
