Crest ProHealth toothpaste is worse for staining than the mouthwash FWIW.Same thing happened to me...my teeth were black within 6 months. I couldn't figure it out. I went to get my teeth cleaned...and my dentist asked if I was using Crest Mouthwash, and that it was infamous for staining teeth. I complained to Crest and Procter & Gamble, who owns them, replied. I asked them to pay for my cleaning. They sent these long forms and told me to send them $150 cleaning bill. It cost me $3 to send, because they are in Europe. They sent me back a $5 gift card. What a joke. P&G is a huge company...and this is how they treat customers. Selling horrible products, and then skirting responsibility. And still selling it to this day. I have since avoided their products, and hope others do too. Shameful.
After my bad staining experience with Crest ProHealth toothpaste and mouthwash, I switched to Sensodyne toothpaste and Listerine Zero Alcohol mouthwash - I've had several cleanings since then and no more staining, and alcohol dries out the tissues in your mouth so I am avoiding that as well.I don't have any teeth staining. I've been using Cepacol for many years. I use a small amount to rinse before brushing. I like the overall "tingly" feel using it as pre-rinse. '
Mix just prior to use. The combo releases an atom of oxygen from the hydrogen peroxide that is starved for an electron in it's valence shell. This oxygen atom binds with odor causing bacteria, killing it. Actually, it burns it up as oxygen is a fuel.The best mouthwash is NaHCO3 + H2O2.
Tastes awful. Don’t swallow.
Cleans really well.
