hi,
I would like to start sublingual methyl b12 but heard it could cause loss of tooth enamel. Has anyone heard of this or had this experience?
I sure would appreciate some information on this. Thank you for any replies.

It will work the same in the body if you swallow it. No need to dissolve in the mouth.

Hi Mrs. D,
Thank you for answering. I read that many people have trouble absorbing b12so that the sublingual bypasses that and goes directly into the blood. I'm confused.

Not much gets thru the oral membranes... cobalamin is a huge molecule and hard to absorb.

Most of the sublingual dissolves in your saliva and you swallow it.
So take on an empty stomach for best results. This is why such a high dose is needed orally.

I have made a general informational thread about B12 here:

Most of the new studies on oral tablets do not use sublingual.
Some of the sublinguals are hard little things...so chew those up and swallow.

I can't answer the part about tooth enamel, my teeth were ruined by gluten to begin with, and in the over 4 yrs that I have been taking B12, I do not think they are any worse.

As for swallowing, or letting it dissolve, there is a lot of controversy over it. Some believe it doesn't matter, some believe it is very important to let it dissolve. I believe letting it dissolve is best, some does get absorbed, if you just swallowed, it's all in your stomach at once. My neuro said it comes in a nose spray now, but I haven't checked into that. Some doctors believe it's best to inject it, which bypasses the stomach altogether. I guess it's whatever you feel is best. I can say, in 4 1/2 years, my B12 has slowed my neuropathy progress, and in some instances, it has improved it, so I will continue to take it my way.

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.

Many people get receding gums as they age. This is partly due to lack of nutrients to support the gums or heavy brushing. Taking drugs that dry the mouth make it worse.

The exposed tooth there has no enamel and will react to things like salt, sugar or other chemicals and is very susceptible to decay.

You can swallow the B12, but make sure you do so on an empty stomach.

I have also heard a few times that letting the B12 desolve is best. I personally don't want to take any chances right now so i am doing what I am told. I am actually going to be calling a specialist monday because I don't feel I am getting the proper treatment for my defiency... but that is another message... anyway...

I did notice that right after I started the b12 I was feeling a bit of an ache in my teeth. but that was only the first few times. Maybe its a reaction and something you both adjusts to. I am sure it's fine, but it wouldn't hurt to ask a professional. good luck
