Dental hygiene is important — as is taking pride in your “pearly whites.”
But keeping your teeth bright and white can be a challenge, with various factors causing discoloration.
Dr. Ronald Santana, head of science and development at Oral Biolife in Pennsylvania, noted that tooth discoloration refers to the “staining or darkening of teeth” from internal or external factors.
“Extrinsic discoloration is caused by color changes of the tooth enamel by external factors such as smoking, foods or beverages, including coffee, tea and red wine,” he said in a statement to Fox News Digital.
