When the gums have pus, it is recommended not to go for scaling. This is because the ultrasonic vibration used in scaling, the process of rinsing the calculus, may cause slight irritation and damage to the gums, resulting in bleeding gums, as well as the gums may rupture the abscess, which may result in a phenomenon of cross-infection, leading to an increase in the patient’s sense of pain, and also require additional treatment. When there is an abscess in the gums, it is advisable to treat the abscess first and wait until it is completely eliminated before going for scaling. Gums with abscesses are most likely due to periapical inflammation, or chronic periapical inflammation, but may also be due to other causes, which can be diagnosed and treated by a dentist, and then scaling can be performed after the abscesses are cured.
