What does mater alba refer to in dental hygiene?

Mater alba refers to a soft, bulky, and white or yellowish material that can accumulate on the teeth and surrounding tissues. It is a mixture of debris, food particles, and bacteria, often appearing as an accumulation that can sit on tooth surfaces without the hard, calcified quality of calculus. This material is different from dental plaque, which is a more organized biofilm that contributes to various dental issues. Mater alba is of concern in dental hygiene because it can lead to plaque formation if not properly removed through effective brushing and flossing, highlighting the importance of proper oral hygiene practices in preventing dental disease.
