Crest Pro-Stain
For your ironic news of the day:
Crest Pro-Health mouthwash users have been complaining that their teeth are stained brown and they suffer from a loss of taste after use. Crest has actually offered to pay dentist bills.
Hi.
I'm sorry. Some people who use an antimicrobial product such as Crest Pro Health, may experience some tooth discoloration. This is true especially among those people who experience a lot of tartar. Unlike stains due to smoking or beverages which can discolor the entire tooth, antimicrobial tooth discoloration can occur in hard to brush areas like between the teeth and at the gum line. This type of staining is only temporary and on the surface of the tooth. We will share your information with our Health and Safety Team who will follow-up with you regarding your dental expenses.
Thanks for writing.
