An electric toothbrush can cost anywhere from $40 to $300 or more. The exact cost of an electric toothbrush hinges on several factors, including the brand, features, and model. Models with fancy, high-tech features usually cost more, whereas simpler models with the basics are generally more affordable. Remember, you don’t have to spend hundreds of dollars on an electric toothbrush to get a good-quality option. Some excellent models are priced much more affordably than a several-hundred-dollar price tag.
