You’ve probably heard that electric toothbrushes can be more effective than their stationary brethren, but how exactly do these tools work? What makes them more effective and how do they move across the teeth? Although different models have different designs, the basic mechanics are the same for all electric toothbrushes.
According to ExplainThatStuff.com, there are two major parts to electric toothbrushes. The first is the outer casing, which holds the cam and gears, the circuit board, the battery and the motor; the second is the detachable head, which is used for actually brushing your teeth.
Most electric toothbrushes are comparable in design to beard trimmers, though the gears that control the brush head are different than those that control blades on a razor. It allows the toothbrush head to both spin and reciprocate at the same time, which allows the bristles to agitate bacteria, plaque and food particles on your teeth.
The circuit board is attached to the on/off switch on the outer casing, which allows the user to control whether the brush is operating and at what speed. The functionality of electric toothbrushes vary greatly; some have several speeds and other options to control your brushing experience, while others are simply in comparison.
The motor is operated by a rechargeable battery, which is powered by the base unit. Electric toothbrushes must be charged between uses if you want them to work properly, and failing to charge your brush on a regular basis will eventually allow the battery to die completely.
Brush heads for electric toothbrushes are typically long and narrow with a round collection of bristles on the end. It can be easily snapped on and off the outer casing, which is helpful when multiple people use the same device, and the bristles may vary in length, width and shape to help reach as many parts of the tooth as possible.
When you use electric toothbrushes, the oscillating motion of the brush head is designed to cover the tooth area completely and remove any stubborn plaque or food particles that might remain. These brushes are just like the regular kind in that they should be used with a healthy dose of toothpaste, and they should be cleaned regularly if you want the product to last a long time.
Additionally, the exterior of electric toothbrushes can look different. Some have texturized handles with rubber-coated buttons to facilitate a better grip and easier functionality, and some are brightly colored or otherwise decorated. However, the real question is whether or not they work properly, so make sure to look at the features of each product before making a decision.
