I have bad teeth due to having my wisdom teeth and infections in them for so long, and not having money or insurance to pay to have them removed for a very long time. Since I started using this toothpaste, my teeth and gums hurt, but in a good way. I have seen an improvement in my buildup, and I am looking for a new dentist to do a deep cleaning to help remove the years of buildup now that my wisdom teeth and infections are gone. It feels good to be able to brush my teeth and it not feel like I am brushing them with acid. I look forward to the day that it doesn't hurt at all to brush them. This toothpaste does not require you to use a lot, and I have only used it 3 times since I got it on the 3rd of January. What I have seen is a major plus that I think will be much better if I have a dentist do a deep cleaning, since this toothpaste would work well as a preventative, even though it has already removed more than I expected it to in the first 3 brushings (tonight will be number 4). I will definitely be buying more, and I will likely stop buying any other toothpaste. It should be known that I use a super soft manual toothbrush to brush my teeth because I tend to brush with a heavy hand.
