Using the heel or toe of the brush is effective for cleaning which surface?

1. Occlusal surfaces

2. Buccal surfaces

3. Lingual surfaces of anterior teeth

4. Distal surfaces of molars

The correct answer is: Lingual surfaces of anterior teeth

Using the heel or toe of the toothbrush is particularly effective for cleaning the lingual surfaces of anterior teeth. The design of most toothbrushes allows for effective cleaning of these surfaces, which can be more challenging to reach with the bristles alone. The heel or toe, which refers to the back or front part of the brush head, can effectively target the hollows and contours of the lingual surfaces. The lingual surfaces are often prone to plaque accumulation, making effective brushing essential for optimal oral health. By employing the heel or toe, the user can angle the brush to reach these difficult areas, ensuring a thorough cleaning that protects against decay and gum disease. Other surfaces, such as the occlusal surfaces of molars or the buccal surfaces of teeth, may utilize different brushing techniques or parts of the brush for optimal cleaning, but the specific maneuvering with the heel or toe is most suited to the unique structure of the anterior teeth's lingual surfaces.
