I got my lower tooth filled a month ago and had a complete ultrasonic scaling on the same day. I was having too much sensitivity at the time of scaling and it was uncontrollable. The dentist gave me local anesthesia for the sensitivity. I also complained of my tooth sensitivity which I was facing. After the treatment, I was advised to use a desensitizing toothpaste but still, I face the same issue when I eat icecreams. Does a desensitizing toothpaste take at least some months to work on sensitivities?
