Visible holes or pits in the tooth enamel

Jaw clenching

The correct answer is: Visible holes or pits in the tooth enamel

One common sign of tooth decay is the presence of visible holes or pits in the tooth enamel. Tooth decay occurs when the hard outer layer of the teeth, known as enamel, gets damaged due to the acid produced by bacteria in dental plaque. This acid demineralizes the enamel, leading to the formation of cavities, which manifest as holes or pits. These visible signs indicate that the decay has progressed sufficiently to compromise the structural integrity of the tooth, which is crucial for maintaining good oral health. Other signs of tooth decay may not be as definitive or visible until the condition worsens, making the identification of holes or pits a critical warning for dental intervention.
