What is the general and specific features of the primary dentition?

The primary dentition, commonly known as baby teeth, consists of 20 teeth that typically emerge between six months and three years of age. General features include smaller size, whiter color, and a more rounded shape compared to permanent teeth. Specific features include the absence of premolars, with only incisors, canines, and molars present, and the presence of wider primary molars that help guide the development of the permanent dentition. Additionally, primary teeth have thinner enamel and dentin layers, making them more susceptible to decay.
