Primary teeth are characterized by having fewer cusps compared to permanent teeth. This difference is an important aspect that relates to their overall structure and function. Primary teeth, also known as deciduous or baby teeth, are designed to accommodate a smaller jaw and assist in the development of speech and chewing habits for young children.

In contrast, permanent teeth typically have more cusps to enhance their ability to grind food, which is necessary for a more varied diet as humans mature. The design of primary teeth reflects their role in helping guide the eruption of the permanent teeth that will follow.

While it is true that primary teeth are smaller, less durable, and erupt earlier in life than permanent teeth, the characteristic feature regarding the number of cusps distinctly sets them apart. Understanding these differences is crucial for anyone studying dentistry, as it impacts treatments and the management of a child's oral health.
