The nano-bubble cleaning technology of the AO3 oral irrigator uses high-frequency water molecule cutting to produce nano-bubbles and negative ion water flow. The physical effect of the nano-bubbles and the chemical effect of the negative ions can effectively clean the dental plaque, dirt, and foreign objects on the surface of the gums and oral cavity. This leads to the removal of stubborn tartar and plaque.

Additionally, the AO3 oral irrigator has a robust gum effect. The nano-water bubbles produced by the device bounce off the gum surface with a rounded arc before bursting, generating powerful vibration and impact forces. This is equivalent to countless water hammer massages on the gums at high frequencies, which do not cause gum pain or bleeding like traditional oral irrigators. It helps to better protect gum health and improve gum robustness, which is the fundamental basis for healthy teeth.
