Types of Teeth Stains:

Based on the causes there are three types your teeth can be stained.

Extrinsic Teeth Stains:

This refers to the stains that happen on the outer layer of teeth i.e. enamel. The food particles with color when accumulate on the enamel, they produce tartar and eventually plaque which can cause discoloration of teeth. The plaque with these stained food particles gives an impression of discoloration, not the actual enamel layer.
There are certain foods that are most likely to cause tooth discoloration like tea, coffee, tobacco, blueberries, coca cola etc. If you take extremely good care of your dental hygiene, these are unlikely to happen as brushing with a good toothpaste and flossing will likely take care of it.
The stains of different colors on teeth represent different reasons why this particular discoloration occurs. These stains can be brown, yellow, green, orange and black.
Brown: This color is normally a sign of oral hygiene and they normally occur due to nicotine from cigarettes and other tobacco products, cola, tea, coffee, red wine, pomegranate, blue/blackberries and the formation of tartar. Tooth decay can also cause brown spots due to acid activity when sugary foods are consumed.
Black: These spots are less common and happen because of presence of iron in the saliva or the use of iron-containing oral solutions. A certain kind of reaction produces these black spots. Tartar buildup in some cases also produces black stains. Tooth decay can also be a reason.
Yellow: This is can be a result of poor dental hygiene and can be solved by brushing daily. It can also be because of worn enamel and exposed dentin which can color your teeth yellow accumulation of biofilm or plaque when food like tobacco is consumed.
Green and Orange: These stains are because of accumulation of chromogenic bacteria and fungi that accumulate because of poor hygiene.
As you can see, all these colored stains can be avoided by taking care of your oral health every day.

Intrinsic Teeth Stain:

Intrinsic staining is caused when erosion of enamel occurs and the stains steep deeper into layers of teeth. They can be of different colors like yellow, brown, grey or orange. Excessive use of fluoride is normally connected to intrinsic staining. Moreover, demineralization and hypocalcification can also cause intrinsic staining.
These stains cannot be removed by merely cleaning them every day. You will need professional help to get them cleaned through bleaching, teeth scaling or polishing. Some methods including tooth whitening products like strips or pastes can be used as well in some cases.

Age Related Stains:

With age, our teeth gradually discolor. The enamel gets thinner and exposes inner layers, like dentin, to the outside elements like the food you consume. It, certainly, is also worn down by many years of use and being under the influences of food and beverages that harm you enamel and other layers underneath.


Causes of Teeth Stain

There are quite a few causes of staining. Following is an elaborate explanation of all causes:
Food: Different types of food and drinks, sugary or otherwise, can stain your teeth. A few examples of food that causes discoloration include coffee, tea, cola, red wine, turmeric, blueberries, tobacco and many other. Any food containing artificial colors can also cause the same effect on your teeth.

When enamel wears off, the spots can develop on inner layers. Poor oral hygiene can make these spots permanent.
Tobacco: Use of tobacco and its products is a common cause of discoloration in your teeth. Nicotine particles stick in teeth causing discoloration. Tar produced during burning of tobacco is a brown sticky substance that can coat inside of your mouth and your lungs. It is also cancerous and can cause mouth, throat and lung cancer.
Oral Care: If you are not taking care of your oral hygiene by brushing twice and flossing daily, you are giving an opportunity to the discoloration elements to remain on your teeth and cause permanent discoloration. It is important to maintain good oral hygiene for the health of your teeth.
Tartar: Poor oral hygiene also encourages development of tartar. Food particles mixed with saliva form a sticky film on the teeth that is called plaque. This plaque, if not removed, can harden over time and form tartar. This tartar can cause yellowing or discoloration of your teeth.
Tartar buildup can cause tooth decay. The acid produced from tartar can bore a hole in your teeth causing dark colored decay holes. Therefore, tartar not just colors the teeth yellow but also causes black colored decay in teeth.
Trauma or Disease: There are a few diseases that can cause discolored teeth like fluorosis, enamel hypoplasia and celiac disease.
Medical Treatments: There are certain kinds of medical treatments and medications that can cause discoloration of teeth. Medications like tetracycline, glibenclamide and chlorhexidine can cause stains. Moreover, medications used for chemotherapy, high blood pressure and antihistamines can also cause discoloration.
Aging: Aging causes teeth to wear down which means that the outer layers like enamel start wearing off and exposing inner layers. Enamel is basically what shown whiteness in your teeth and when it wears off its shows yellow colored dentin causing yellow teeth.
Dental Filling, Crowns and Bridges: If you have previously done dental work like fillings, crowns, bridges or implants etc., they can lose their whiteness over time.
