Vitamin C and Teeth.

What about the Ascorbic Acid damaging my teeth?
I have been taking the Liposomal vitamin C for almost a year and went for a check up a couple of weeks back and my dentist was amazed at how healthy my gums and my teeth were.  However, I did notice a slightly higher sensitivity on my teeth when he did the sensitivity tests. In response to this sensitivity my dentist told me to swish and spit out some  bi-carb mixed with water after each of my Liposomal vitamin C doses as a way of quickly neutralising any acid that could have come in contact with my teeth. I now have a bottle of pre-mixed bi-carb and water next to my vitamin C bottle ready to swig, swish and spit.

My bi-carb and water premix consists of  2 teaspoons of bi-carb in 250 ml of water.
I shake the bottle before I swig, swish and  spit.
