A mild tasting toothpaste that is very effective at both gently cleansing and gradually filling in cracks and fractures. I had a chip off of one canine that was actually starting to be painful. I have every motivation not to seek dental treatment because of special needs that require I be under general anesthesia in a hospital operating room as a high risk surgical patient. The last time I had dental work, I sprang a rare reaction, they could not use the one reversal agent every OR has to have on hand for this rare reaction. The board-certified Harvard-trained anesthesiologist had to use other means to bring me through. I no longer can travel the thousands of miles to this one specific hospital that knows my case, which is also why I was looking for some way to fill this chipped tooth on my own. I have been treating this tooth for several months by brushing everywhere but this tooth and holding the paste in the mouth for a time before rinsing out well. I have, concurrently, been using the "Shine" powder, not to clean but as a crevice filler because it strikes me as possibly too abrasive. "Shine," however, is grittier, has some interesting animal-based ingredients, and lacks the glycerin that is present in the Himalayan formula, meaning: adherence ought to be more effective without the oil slick. The non-nano "Shine" seemed to be the most helpful in the beginning of my self treatment. However as I gradually built up a protective initial layer on the tooth, this smoother Himalaya formula with the nano hydroxyapatite worked much better as a "finisher" to consolidate and maintain the tooth coating I had slowly built up. I am not claiming a permanent solution, nor am I claiming that it is possible to achieve what I have without diligence and care and real time. There is no substitute for seeing the dentist if you are in trouble. I am only reporting that this toothpaste works IF you do your twice daily maintenance work and eat carefully around a tooth that is slowly mending. The pain is now gone, the tooth surface is smooth. It feels like any other tooth in my head. Yes, this toothpaste is pricey but a tiny amount on a wetted toothbrush goes a long, long way and generates lots of foam. It does not leave a gummy residue on the rest of one's teeth like the "Shine" powder does. The taste is a mild, very smooth mint, not at all overwhelming. Excellent product.
