The proper or the right time taken to brush one's teeth lasts for two minutes or 120 seconds.
The correct method involves brushing of the teeth twice a day that prevents tooth loss, gum disease and decay. Hold the toothbrush at a 45-degree angle preferably using a soft-bristled toothbrush and brush with short strokes that are half-tooth-wide that reach the gum line. Use a rolling motion to brush the outer surfaces of the upper and lower teeth. Brush back and forth against the chewing surfaces of the teeth holding the toothbrush in a flat position. Hold the tip of the toothbrush in a vertical position using an up-and-down movement on the inside of the teeth. Use a back-to-front motion with the toothbrush to clean the tongue for fresher breath.
