Excellent product, works exactly as described!
My teeth are called &#34;soft teeth&#34;.  This means the enamel has never been as strong or as thick as it should have been.  They have always been prone to unexpected enamel cracking and deterioration, irregardless of fluoride toothpastes, remineralization oral rinses or a strict sugar free diet. This product has desensitized my teeth and appears to have strengthened the enamel. Have had no further issues with unexpected enamel chips since regularly using gel. Wish I had been able to use this product for my entire life.  What a difference it would have made.  Thank you Dr. Song!
