I have noticed that in my patients who've undergone dental prophylaxis, a yellowish calculus tends to build up along the tooth surfaces--usually within six months of the cleaning. With only a glance, I can always tell that we have cleaned a patient's teeth in the past. Do you have any suggestions or insight for us?
