Uses of Dental Mirror

Now let me explain for what purposes these dental mirrors are used. These dental mirrors have four important functions in dentistry.

  1. Indirect Vision: – There are many objects in an intraoral structure that cannot be seen directly. Indirect vision mirrors become a great use to view these tooth surfaces.                                                                                                                          
  2. Indirect Illumination: – As illumination means lightening you may have got an idea as these mirrors help to reflect light onto teeth and other dark surfaces of the mouth.                                                                                                                             
  3. Retraction:- You may have seen a dentist holding cheeks, tongue, or lips to view all those hidden surfaces. For example, like in retraction of lips, we raise lips upward to view the upper teeth and gums.                                                                                 
  4. Transillumination – This is another effective method to identify the cracks in teeth. This is also called a light detector that will surely confirm whether there is a crack on teeth or not.
