I started using Colgate whitening toothpaste and after only 2 days my teeth and gums were in so much pain. My lips are swollen and my jaw is sore. I went to the dentist worried that I had an infection. He said it was from the toothpaste. I am on painkillers and stopped using the product. This should be taken off the market. I am unable to eat and drink without severe pain. My cheeks are also swollen. I have been in pain for 5 days now and hope it is better soon. Colgate should compensate all the customers who have had these horrible side effects.
