I have been told by some dentists that make no difference, just saying.Also, I wonder if drinking it through a straw is better for the teeth.
Also using a straw is not standardized so to speak, so drink it from the lips almost some a bit behind the lips.
I have tried with the straw really far back to help out contact with teeth and unfortunately the taste and satisfaction was not there if the straw was too far back on the tongue.
No to mention even the straw seems to matter, especially if it is a paper straw.
