Yellowing of teeth is a fairly common phenomenon that can be caused by a variety of factors:
Exogenous pigmentation: Certain foods and beverages, such as coloring-containing beverages such as coffee, tea, red wine, and cola, as well as certain condiments, such as curry and ketchup, can leave pigment on the surface of the teeth.
Smoking is also a common cause of yellowing of teeth, with the tar and nicotine in tobacco forming yellow or brown spots on the surface of the teeth.
Natural aging: As we age, the outer layer of white enamel wears away, exposing the yellow dentin underneath.
Oral hygiene: Teeth may become discolored if you don't brush your teeth regularly or floss to remove plaque and tartar.
Medications*** Certain medications, especially certain antibiotics such as tetracycline and doxycycline, can cause tooth discoloration in young children.
Long-term use of fluoride-containing products, certain mouthwashes or tooth cleaners may also cause tooth discoloration.
Dental disease: Teeth may turn yellow or darken after tooth damage, death, or root canal**.
Genetic factors: The color of teeth can also be influenced by genetic factors, and some people are born with yellowish teeth.
If you are bothered by yellowing of your teeth, you can consult a lab coat and they will provide you with methods such as cleaning, whitening or other ** methods depending on your specific situation. At the same time, maintaining good oral hygiene, regular teeth cleaning, and moderation of foods and drinks that cause tooth staining can all help maintain the brightness of your teeth.
