This approach can certainly increase the anxiety both on parental and child’s front. Waterlase or Erbium laser-based dentistry has traversed a unique pathway where laser pops are used to remove the decays, followed by filling.
Since laser does not come in contact with the tooth structure, there is no pressure sensation on the tooth. This takes care of the numbing part. We don’t need to use needles or shots to numb the tooth prior to laser fillings. In case there is very deep carious decay and child is very sensitive or apprehensive, a small infiltration i.e. few drops of anesthesia are used.
