Every dental treatment doesn’t give you pain or discomfort as it depends on the specific procedure involved and the skills of the practitioner, whether he is experienced or not. Some well-trained practitioners give numbing agents to the patients before starting the procedure to minimize the pain. As if talking about teeth whitening which just causes temporary tooth sensitivity and gum irritation. It just gives mild pain. And if we talk about the veneers treatment, the experts give local anesthesia to minimize the discomfort and the same as in all orthodontic treatments. A mild pain will be felt at the start, but it will subside with time.
