Mouthwash with fluoride, according to Dr. Dan Peterson of Family Gentle Dental Care, can reduce the bacteria that causes cavities by 50 percent. Additionally, therapeutic rinses prescribed by a dentist are beneficial in preventing the buildup of bacteria due to periodontal disease, dry mouth or a condition that prevents an individual from brushing regularly.

On the Other: Mouthwash Without Flouride

However, over-the-counter mouthwashes that do not contain fluoride are considered by Dr. Peterson to be no more beneficial than rinsing with regular water, which will dislodge food particles, but does not prevent plaque buildup or cavities. Additionally, Zbys Fedorowicz of the Ministry of Health in Bahrain suggests that some mouthwashes can stain teeth, leaving a temporary but unsightly colored film on the teeth and tongue.

Bottom Line

Individuals suffering from bad breath, dry mouth or other dental problems should consult a dentist for a prescription mouthwash that kills bacteria. Those who do not have dental problems can rinse with water after eating to dislodge food particles instead of using over-the-counter mouthwash.
