Dearest Lufflies (ewe know I luff ewe guys and gals dont ya ? )


See Barrington Ethelbread The Third brushing his teeth ?




He's a good cat, a klevur cat, a cat with clean teeth !

.....however,

he just drank some of this stuff !




Ewe'd normally think...not a problem...best thing to do is brush your teeth after drinking juice...but Barrington then went on learn that ewe should wait a good thirty minutes or so after drinking orange juice before brushing your teeth !!...why's that then ?

Won't the excess juice lingering in his mouth continue to harm Barringtons teeth ?...so why the need to wait for half an hour ?

Do ewe know !

I don't ...I want to !!



hugs

Yep we do!

Perhaps being so acidic, the acid might help to remove or loosen plaque for brushing.. or perhaps the teeth absorb vitamin c and this gives it time to penetrate without harming them???? I really don't know but that would be my guesses!

Here is advice given to bulimics.. 

Quote
It is very important to not brush your teeth after vomiting. While it takes the taste away it can cause extra damage to the teeth by damaging the surface crystals on the enamel layer of the teeth. The best option is to wash your mouth out with plenty of water and wait several hours before brushing your teeth or eating anything acidic such as fruit or fizzy drink. This allows the saliva to neutralise the stomach acid which seeps into the surface enamel after vomiting. Brushing your teeth destroys the protective layer of enamel, making it easier for the acid to attack it.

I'm no specialist in this field, but I always thought that acidic foods (like fruit juices) temporarily soften the enamel, so if you brush your teeth when they are soft and vulnerable you risk wearing them away rather quickly -- and maybe getting sensitive teeth?
