In what direction should the polishing stroke be applied?

The polishing stroke should be applied from the gingival third toward the incisal or occlusal surface because this technique effectively removes plaque and debris while minimizing trauma to the gingival tissue. By directing the stroke in this manner, the dental assistant is ensuring that the polishing agent moves away from the gums and toward the tooth surfaces, which helps in maintaining periodontal health and preventing irritation or damage to the gingiva. This technique also enhances the effectiveness of the polishing process, allowing for the smoothening of the tooth surface in a controlled manner, thus contributing to the overall oral hygiene of the patient.

Additionally, this forward stroke aids in creating a clean and polished surface, improving the aesthetic appearance of the teeth while helping to reduce the potential for future plaque accumulation. Using this ascending motion is aligned with the natural direction of tooth surfaces and encourages better results during the polishing procedures.
