Oral - B Professional Toothpaste Is Causing Mouth Sores

Since using this product, I have developed painful mouth sores. I am concerned about the potential harmful ingredients in this toothpaste and believe it may be a case of product tampering or a manufacturing error. upon researching online, I discovered that several other consumers have reported similar issues with this particular product. Given the recurring nature of these complaints, I believe there is a serious problem with the toothpaste's formula. I demand a full refund and a thorough investigation into this matter. I expect a prompt and satisfactory resolution to this issue.
