To clean your teeth effectively:

• Start with the back teeth and work your way towards the front teeth.
• Hold the nozzle at a 90-degree angle to your teeth and gumline.
• Gently glide the nozzle along the gumline, pausing briefly between each tooth.
• Ensure the water stream reaches between teeth and along the gumline to remove plaque and debris.
• Clean the outer surfaces, then the inner surfaces, and finally the chewing surfaces.
