A dental bracket has a base and an engaging unit. The base has two engaged protrusions and two limiting protrusions. The engaging unit is mounted on the base and forms a space between the base and the engaging unit. The engaging unit has a plate, two engaging arms, and a blocking protrusion. The plate has a first surface and a second surface being flat and opposite the first surface. The two engaging arms are formed on the first surface of the plate and respectively engaged with the two engaged protrusions of the base. The blocking protrusion is formed on the first surface of the plate, is arranged between the two limiting protrusions of the base, and divides the space into two channels for inserting an archwire. The second surface of the engaging unit is flat and is able to decrease the foreign body sensation in the mouth.
