Does using hydrogen peroxide as a mouthwash dry out the gums?
Use 3% Hydrogen Peroxide and dilute with equal amount of water to get 1.5% concentration. Then use it as mouthwash for up to 60 seconds. I saw a dentist on tv personally recommend this as an alternative to alcohol based mouthwashes, as they dry out the mouth and allow high levels of bateria to grow. I have been using it and feel it works very well, just be careful not to burn your mouth. If you feel pain, either your concentration is too high, or your rinsing for too long. Concentration and contact time is what is important to kill bacteria and not your oral tissue.
