What is a common indicator of gingivitis?

1. White spots on teeth

2. Pain when chewing

3. Reddened, swollen gums

4. Cold sensitivity

The correct answer is: Reddened, swollen gums

A common indicator of gingivitis is reddened, swollen gums. This condition typically arises from the accumulation of plaque and bacteria along the gum line, leading to inflammation. When the gums are irritated, they may become visibly red and swollen, which is a hallmark sign of gingival inflammation. This response is part of the body's immune reaction to the irritants, and it can also be accompanied by other symptoms such as bleeding during brushing or flossing. Other indicators such as pain when chewing, white spots on teeth, or cold sensitivity are not specifically characteristic of gingivitis. Pain while chewing may suggest a more advanced dental issue, such as cavities or tooth infections. White spots on teeth could indicate early demineralization or decay, and cold sensitivity often points to enamel erosion or exposed dentin rather than gingivitis. Therefore, the condition of reddened and swollen gums serves as a primary visual and tactile cue for the early diagnosis of gingivitis.
