Imho, baking soda is very abrasive. I don’t have veneers, but I don’t use it. I prefer gel tooth”paste”.
Your opinion is worthless... go with the science and the engineering. The MOHS Hardness scale puts Sodium Bicarbonate (Baking Soda) at 2.5... very soft... Talc is 1, Tooth Enamel is 5.
Gel tooth paste still has suspended abrasives in it... usually pumice.
