I had my teeth cleaned in the first week of Feb 2011. The Dr said I will have some pain and hot & cold sensitivity for some time. But I am having tooth sensitivity on my right upper tooth even now. The filling from my upper tooth had come out about 2 years ago but I did not have any problem because of it. Is the pain due to some inadvertent mistake on the part of the Dentist or due to the method of the cleaning (laser or ultrasound - I am not sure). Can this pain be relieved ?
