Yellow and discolored teeth indeed look pretty disagreeable and they are source of embarrassment in society। Bright smile give beauty to your face and people who have discolored or yellow teeth often do not smile to offset their unpleasant teeth.
Before I will tell you the treatment options for yellow teeth , you should know what are those factors that are causing your teeth look yellow.
1. Some people have yellow teeth from birth (originally yellow). If you belong to this category you don't need worry about anything because your teeth aren't diseased. All you have is defective enamel (outer layer) mineralization defect and the second layer which is yellow coloured called dentin is showing off from thin enamel.
2. SMOKING: I don't understand why people smoke?? Its more of a fashion in teenagers and adults but they don't know the long term harms of this crappy thing. People who smoke often have ugly teeth that are brown to black in colour which is because of nicotine(component of cigarrete) that makes salivary pH acidic. No argument , smoking is indeed a major cause of tooth yellowing as well as discoloration.
3. TEA and COFFEE : Excessive intake of tea and Coffee causes extrinsic staining and yellowing of teeth over a period of time because it contains color imparting substances.
4. BAD ORAL HYGEINE : Most of you do not take care of your teeth as much as your skin,hairs,nails etc. Your teeth also need some time to care for them. If you do not brush them properly then they will ultimately appear yellow so no matter how tired you are always brush your teeth before going to bed and also between meals.
5. BEVERAGES and ENERGY DRINNKS: Avoid taking lots of carbonated drinks as they are very dangerous for your teeth, they are corrosive in nature and make your teeth weak and brittle and once they become weak they acquire extrinsic pigmentation easily. Use Mineral water instead of harmful drinks.
6. AGING: As u grow older your enamel wear down due to attrition and underlying dentin appears yellow. Moreover with age people do not take care of their teeth and their bad oral hygeine causes teeth to appear yellow.
7. SYSTEMIC FACTORS : Diabetes mellitus , Congenital porphyria, Amelogenesis imperfecta, Dentinogenesis imperfecta all of them leads teeth to become brittle, porous and less mineralized leading to yellowing with time.
8. SWIMMING: It is not a very major factor but some research has shown that swimmers have weak teeth becausa of high chlorine content in swimming pools which might cause teeth to become brittle and yellow.
9. ATTRITION, ABRASION, EROSION : Do not use your teeth for opening cans and packages. Also people living in rural areas eat hard sugarcane that causes attrition(wearing off enamel). Do not insert needles, pins, pencils between your teeth because this habit again causes fragile teeth.
Improper brushing technique (horizontal brushing) causes abrasion so avoid it.
Excessive vomiting in people who have anorexia nervosa/bilimia nervosa causes erosion which is chemical wearing of teeth (this is usually seen in teenager girls who have fear of gaining weight even if they are underweight and for doing it they vomit out forcibly after taking meal).
TREATMENT OPTIONS:
1. Bleaching and whitening
2. Crowning if one or two teeth affected
3. Porcelain Veeners
4. Composite Veneers
5. Laser technology/treatment
