Why teeth turn yellow regardless of oral hygiene habits

Tooth enamel naturally changes color over time due to aging and external influences. Because enamel is translucent, its thinning allows the yellowish dentin layer beneath to become more visible, causing the smile to lose brightness regardless of hygiene habits. Factors contributing to discoloration include smoking, consumption of coffee and red wine, the accumulation of pigmented plaque, and the formation of micro-cracks. According to dental specialists, darkening can also result from past injuries, certain medications, or chronic oral diseases. Accurate diagnosis by a dentist is required before any aesthetic correction to determine the specific cause of the color change. "It is important to understand that tooth color is determined by genetics and lifestyle; therefore, home methods are often ineffective or even dangerous for the tissue structure," explained dental therapist Elena Voronina to Pravda.Ru.
