455:(5.09-11.13). Whitening toothpastes have a mean pH of 6.83 with a range (4.22-8.35). Mouthwashes also vary greatly in pH from pH 4.40 to 6.80. Mouth rinsing after an acidic challenge increased salivary pH. The tested mouthwashes raised pH higher than water. Mouthwashes with a neutralizing effect can potentially reduce tooth erosion from acid exposure. Essentially the human mouth is an optimum habitat for this organism and any pH level alteration needed to stunt the reproductive rate significantly would require a duration of time that would cause greater damage to the tooth enamel than to 67: 244:
