If left untreated, what condition may plaque buildup lead to?

Tooth decay
Gingivitis
Pulpitis
Periodontitis

The correct answer is: Gingivitis

If plaque buildup continues to accumulate on teeth, it can lead to the development of gingivitis, as bacteria in the plaque can cause inflammation of the gums. While tooth decay is a concern and can also be caused by plaque, this occurs on the surface of the tooth and does not necessarily require treatment if caught early. Pulpitis is more commonly caused by dental trauma or a deep cavity, and periodontitis is a more advanced form of gum disease that can lead to bone and tooth loss. Therefore, B is the most likely and immediate consequence of untreated plaque buildup.
