Detailed Description
The following describes the embodiments of the present utility model in detail with reference to the drawings.
In one embodiment of the present utility model, as shown in fig. 1, a dental electrode capable of avoiding secondary infection is provided, and as shown in fig. 1, the dental electrode comprises a dental electrode body 100, wherein the dental electrode body 100 can comprise an electrode tip 110, an insertion part 120, a handle 130 and functional components, and the functional components comprise a power connector 150, a negative pressure device 140 and a drip chamber 150.
