- Handle Shape: The handle should be easy to grip and comfortable to hold. It may be curved or straight, depending on personal preference, but should fit snugly in the palm of the hand allowing for full range of motion.
- Grip Material: The handle material should be non-slip and textured for a secure hold. It should be durable and resistant to wear and tear, as well as easy to clean and maintain.
- Head Size and Shape: The head of the toothbrush should be compact enough to reach all areas of the mouth comfortably, but not too small that it requires excessive brushing. The shape should allow for easy maneuvering around the teeth and gums, and the bristles should be arranged to effectively clean the teeth.
- Bristle Density: The density of the bristles should be medium-soft to avoid causing damage to the teeth and gums. The tips of the bristles should be rounded to prevent any sharp edges from causing discomfort.
- Bristle Length: The length of the bristles should be short to medium, around 10 to 12 millimeters, to allow for effective cleaning without causing irritation to the gums.
- Overall Size and Weight: The toothbrush should be comfortable to hold and lightweight, for easy maneuverability.
Some ergonomic toothbrushes may also feature:
- Angled heads to reach hard-to-reach areas
- Pivoting heads to adapt to different angles and surfaces
- Non-slip grips for added stability
- Indicator bristles to signal when the toothbrush needs to be replaced
