Comparison AENO DB8 vs AENO DB7

The purpose indicates for whom an electric toothbrush or set is designed. In electric brushes, this is important not only due to the size of the head but also due to the power of vibrations/rotations, cleaning modes, pressure sensor, and the comfort of the handle.

— Adult toothbrush. Adult electric brushes are intended for permanent teeth, a larger jaw, and the usual cleaning pressure. Such models are generally not suitable for children due to the large head, higher intensity of movements, and a body that's difficult to hold with a small hand. For example, an adult electric brush works well with plaque along the gum line or around braces for teens and adults, but for a younger child, it's better to choose a separate children's model.

— Adult toothbrush 2 pcs. A set for two adult users includes two full electric toothbrushes, each designed for individual daily use. This is a convenient option for a couple or family where everyone needs a separate handle with a motor, rather than just different attachments on one brush.

— Children's toothbrush. A model for children is created taking into account small teeth, delicate enamel and gums, as well as an uncertain brushing technique. It differs from an adult toothbrush with a smaller head, more gentle intensity, and often additional motivational elements, such as a timer, lighting, or a bright design....Often children's brushes are targeted at a specific age, which depends on the size of the head and the bristle stiffness of the head.

— Adult + children's toothbrush. This set combines a full-fledged adult electric toothbrush and a separate children's model adapted to the child's age. It is convenient for family use when an adult needs standard power and head size, and a child needs softer and safer cleaning.

The number of working nozzles that are standardly supplied with the device. Nowadays, options are quite common with both one and two or three nozzles in the kit; and in the most extensive sets, this number can be four or five or even more.

In many sets, several nozzles may have different purposes. For instance, an irrigator, in addition to its standard nozzle, might include orthodontic and periodontal nozzles. However, it's important to note that models with the same number of accessories in the kit can have different specific specializations. So, when making a choice, it's wise to consider not just the quantity but also the types of nozzles available. Additionally, there's an option where several identical interchangeable heads come with one handle. This configuration is particularly common in toothbrushes. It enables multiple individuals, such as family members, to use a single device, and such a set is usually more cost-effective than purchasing individual toothbrushes for each person.
