Dear PoPo,
I was reading about wholistic dental care.
This one dentist recommends making a paste of 3Parts Baking Soda, 1Part table salt. Then pour a tiny bit of hydrogen peroxide into your hand with the mixture. Mix it up to make a paste. Then getting a soft bristle tooth brush and take the paste and work it into your where the top of your gums overlaps the bottom of the tooth. There is a name for that part, I just forget, you probably know.
This is suppoused to strenghten the gums and make sensitivity on teeth less painful.
He also says to use a rubber triangle pick thing once the gums have grown a bit and flossing.
I have not tried it yet, but am interested and was wondering what you thought about this.
