Abstract: The present invention is intended to provide a toothbrush in which the handle of the toothbrush includes a plurality of handle pieces and the handle pieces can be selectively assembled and separated by fitting coupling, screw coupling, or the like, thereby contributing to enabling children to make it a rule to brush their teeth by particularly stimulating the curiosity and interest of the children, and also improving brain development and a learning effect. The present invention provides a toothbrush including: a head (3) into which bristles (2) are planted; and a handle (4) which is coupled to the head (3); wherein the handle (4) includes a plurality of separate handle pieces (4a), and the handle pieces (4a) are selectively coupled to their adjacent handle pieces (4a) and separated from the adjacent handle pieces (4a).

Abstract: The present invention is intended to provide a toothbrush which can increase a contact area between teeth and bristles and further enhance frictional force while a head on which the bristles are planted is elastically moving vertically and laterally in accordance with the shapes of the teeth, which can minimize the wear of teeth and the damage of periodontal tissues attributable to booth brushing by adjusting pressure excessively exerted on teeth by a toothbrush user, which enables a patient with a periodontal disease to more easily use bass technique-based tooth brushing, thereby helping the cleanliness of gums and the health of periodontal tissues, maximizing a tooth brushing effect, and contributing to the improvement of oral hygiene, and which can provide the convenience of fabrication.

Abstract: Disclosed herein is a toothbrush. The toothbrush (1) includes a head (2), and a through hole (3) formed vertically through the head. The through hole (3) is formed in one or more portions by a predetermined length at a predetermined portion around a front, back, left or right of the bristle body (5) to prevent the bristle body (5) from being separated from the head (2). The bristle body (5) and the head (2) are connected to each other by one or more connecting portions. This toothbrush enables the bristle body implanted with bristles to freely and flexibly move upwards, downwards, leftwards or rightwards in the through hole of the head, so that the bristle body flexibly moves so as to adapt to various shapes of the teeth when brushing the teeth, thereby maximizing the contact area between the teeth and the bristles as well as the brushing effect.

Abstract: The present invention relates to a toothbrush, characterized by forming a hole perforated in an up-down direction on a header of a toothbrush, wherein the hole has placed therein a plate having a brush implanted thereon, and the plate is fixed on top of an elastic member fixed on the edge of the bottom surface portion of the header, so as to enable an elastic movement in up, down, left, right directions, and as the plate having the brush implanted thereon elastically moves similarly on the header according to the shapes of the teeth, the contact area between the teeth and the brush increases and the friction increases, to maximize the tooth brushing effect, minimizes the abrasion of the teeth and the damage of the periodontal tissues due to tooth brushing by adjusting the pressure exerted excessively on the teeth by a user, to enable an easier use of Bass tooth brushing techniques and to aid the user in achieving both cleanliness of gums and oral hygiene.

Abstract: Disclosed herein is a dental scaler for removing accumulated deposits from the teeth, having a low manufacturing cost so as to be widely used at home. The dental scaler includes a first casing adapted to serve a grip; a power supply-receiving section and a motor installed at the inside of a first casing serving as a grip, wherein the power supply-receiving section is adapted to contain a power supply device therein and a rotating speed of the motor is adjustable by a first switch. A vibrator is eccentrically installed at a driving shaft of the motor to be selectively in electrical contact with a second switch for connecting or disconnecting a power of an electromagnet An electromagnet-receiving section is formed at the front end portion of the first casing, for containing the electromagnet therein.
