How Do Teeth Lose Their Whiteness?
Teeth losing their whiteness may occur due to many different factors. The most common of these factors are diet, oral hygiene, lifestyle choices, and some health conditions.
Diet: One of the main factors that cause changes in the color of teeth is the food and beverages consumed. Dark colored drinks such as tea, coffee, cola and wine can cause stains on the surface of the teeth over time. Additionally, intensely colored spices such as soy sauce and red pepper can also cause tooth discoloration.
Smoking and Alcohol Use: Smoking is an important factor that causes yellowing and staining of teeth. Nicotine and tar stick to the surface of the teeth, causing yellow or brown stains to form over time. Alcohol consumption, especially dark alcoholic beverages, has similar effects.
Oral Hygiene: Adequate and regular brushing, flossing and regular dentist checks are critical in maintaining the health and whiteness of teeth. Inadequate oral hygiene paves the way for plaque accumulation and subsequent tartar formation, causing teeth to become dull and discolored.
Medications and Health Conditions: Some medications, especially antibiotics such as tetracycline and doxycycline, can cause teeth discoloration. Additionally, excessive consumption of fluoride (fluorosis) or some diseases during childhood can also affect the natural color of the teeth.
Aging: With the aging process, the natural thinning of tooth enamel and the dentin layer underneath becomes more visible, causing the teeth to appear more yellow.
