Parodontax Toothpaste Caused Mouth Pain and Burning

I bought a Parodontax toothpaste from Checkers about 1 month ago, and after using it, I started to have painful experiences. These problems began shortly after I started using the product, and I had not experienced such pain with other toothpastes before. Due to the severity of the discomfort, I consulted a professional about the situation. After this experience, I lost my trust in the product, and I am worried about its safety and possible side effects. I kindly request a detailed formal explanation from Parodontax regarding what might have caused these painful experiences, whether similar complaints have been received before, and whether there is any risk associated with this product. I would also like to be informed about what steps will be taken so that other consumers do not experience the same problem.
