Toothpaste has three main ingredients: \b Abrasives, Fluoride, and Surfactants
\b0 \ \
50% of toothpaste is made of Abrasives which remove plaque and food particles. But that's
nothing compared to crushed \b bones and shells
\b0 that were used by the Greeks. Not everyone had a toothbrush so toothpaste is usually
just rubbed with \b fingers, rags, or a branch \

As an aside, toothbrush does more work than the toothpaste.

\cf0 \ Things did not get better in the
\b 1800s \b0 . Tooth paste was prepared with
\b burnt bread, cinnamon, or burnt alum \b0 . Tooth powder consisted of
\b chalk, pulverized brick, or salt \b0 , which can sometimes to more harm than
good.\ \
\ A lot of things happened between
\b 1890s to 1900s \b0 : the
\b collapsible tube \b0 was invented, so was
\b premixed toothpaste \b0 ,
\b fluoride was used for the first time \b0 , and Volleyball was born. It really was.
In the 50s, striped toothpaste was invented, and the ADA approved fluoride use. \
\b Fluoride \b0 slows down and reverses enamel erosion
but only when mixed with saliva. \b Natural fluoride
\b0 can be found in water, plants, and animals. In the US, toothpaste can contain around
\b 1000 parts per million \b0 and can be up to
\b 1500 in the EU \b0 . Fluoride is also sometimes mixed in
water treatment plants of certain cities. \
\b Pets and astronauts \b0 have special toothpaste that can be swallowed.
But, swallowing normal toothpaste could cause nausea and diarrhea. No one wants
\b space diarrhea \b0 . Fluoride can also be toxic if swallowed
in large amounts. There's also \b teeth whitening toothpaste
\b0 that uses hydrogen peroxide, but it's the abrasives that do the heavy lifting. Results
show up after brushing \b twice a day for three to four weeks
\b0 . \ \
(3rd) \b Surfactants
\b0 (detergent) like \b Sodium Lauryl Sulfate
\b0 , which can be found in shampoo, creates foam which distributes paste more evenly.
Though I'd imagine that it was a great \b marketing
\b0 opportunity to be the first foaming toothpaste.\ \
\ The three most popular flavour are
\b Peppermint, Spearmint, and Wintergreen \b0 , but there are also exotic flavours like
peanut butter, apricot, and whisky to name a few.
\b Stannous Fluoride \b0 found in toothpaste could also alter taste.
\b Oranges \b0 are unpleasant while
\b apples \b0 taste great. \
\ In
\b 2007 \b0 , a toothpaste containing poisonous
\b diethylene glycol \b0 was recalled world wide. As you know by
now, we put a lot of \b synthesized chemical
\b0 in toothpaste, and that's why there's \b herbal and natural toothpaste
\b0 which uses natural ingredients. \ \
It still \b blows my mind
\b0 that people used to make tooth paste out of
\b pulverized bricks and charcoal and then rub it in their teeth with a rag
\b0 . Come to think of it, there's probably a
\b hipster \b0 out there trying that right now. \
