Smoothing a filling involves removing any excess material and ensuring a smooth transition between the filling and the natural tooth surface. This process may involve filing down the tooth slightly to create a more natural contour and prevent any discomfort or irritation to the patient's tongue or cheek.
Smoothing a filling is an important step in the restorative process as it helps to ensure the longevity of the filling and the comfort of the patient. A well-smoothed filling is less likely to chip or break, and it will be more comfortable for the patient to bite and chew.
