Tooth whitening is a process of removing discolorations from a tooth. It is one of the most popular cosmetic dental procedures, quick and easy to perform. It can only transform one’s smile and make one look years younger and boost self-confidence. We recommend professional teeth whitening whereby a dentist is involved since it requires following standard procedures.

 

Causes of discoloured teeth

1. Ageing is one cause of discoloured teeth. The natural shade of teeth ranges from light-off grey (off-white) to a slightly more yellow in tint. Overtime as one ages, teeth tend to change in colour naturally.
2. Staining is another factor leading to discoloured teeth. Drinks like coffee, tea, wines and certain foods and vegetables can stain teeth. Poor dental hygiene like inadequate brushing, flossing and rinsing off the mouth using antiseptic mouthwash to remove plaque and stain producing substance like coffee and tobacco causes teeth discolouration.
3. Smoking is a major contributor to staining of teeth because of nicotine. Several diseases that affect the enamel and dentine on the teeth also can cause teeth discoloration.
4. Treatments for certain conditions like head and neck chemotherapy can cause discoloration 
5. Excess fluoride in water or toothpaste causes discoloration.
6. Certain antibiotics are known to discolour teeth, especially when given to children before age 8.
7. Genetics is also a contributor, since some people have a naturally brighter and thicker enamel than others.
