What is the primary concern when dealing with plaque on teeth?

The primary concern when dealing with plaque on teeth is that it can lead to gum disease. Plaque is a sticky film of bacteria that forms on teeth. If not removed through daily brushing and flossing, plaque can harden into tartar, which can irritate the gums and lead to inflammation and infection. This condition is commonly known as gingivitis, which can progress to more severe forms of gum disease, such as periodontitis, if left untreated.

Maintaining good oral hygiene is essential to prevent plaque accumulation and limit the risk of developing gum disease, which can have broader health implications beyond just oral health. This highlights the importance of regular dental check-ups and effective cleaning practices in promoting overall well-being. The other options presented do not accurately reflect the impact of plaque on dental health.
