I just began taking 1000 mcg's of B-12 sublingual "dots" microlozenges yesterday and I immediately noticed that my teeth began aching afterward, as if I had bathed my teeth in sugar! It was a very unpleasant experience. I placed the lozenge under my tongue and allowed it to dissolve before swallowing as per the instructions on the bottle.

Is there something in the vitamin B-12 lozenges that can destroy the tooth enamel? It sure feels like it could.

I started taking these microlozenges rather than paying for the B-12 shots at my doctor's office. I hadn't had my "monthly" B-12 shot in over 3 months and noticed a decline in my energy, mental alertness and ability to remember things. I was hoping the B-12 lozenges would help. Any input would be greatly appreciated.
