What should i brush my teeth with besides toothpaste?

Baking soda: Using a plain toothbrush and floss without toothpaste will still remove the bacterial plaque from the teeth. Baking soda has been used as a substitute for toothpaste.

Why not tootpaste?: Brushing your teeth produces the cleaning result mostly with the mechanical action from the brushing and not so much chemical action from the toothpaste. Any kind of cleaning agent (soap, water, salt) may do the similar job. However, most toothpaste has fluoride. Fluoride also helped with teeth sensitivity and fight decay. If you are allergic to fluoride, nonfluoride toothpaste can be used.

Mouthwash: The toothbrush itself does most of the work when brushing your teeth. Try listerine and you will get about 90% of the beneficial effect of brushing with toothpaste. The only downside will be the lack of Fluoride which will make you more susceptible to tooth decay.

Best is tooth paste: Hydrogen peroxide baking soda.
