Staining of teeth is very common nowadays; this happens because of certain foods and drinks as well as environmental factors. Tooth whitening procedures are gaining popularity in the aesthetically concerned population because of the unsightliness of stained teeth.
The tooth stains or discolorations can be of two types
Intrinsic staining, which is from inside the enamel and starts in the formative phases of tooth development by the consumption of antibiotics like tetracycline by the mother while the child is in the womb or the consumption of fluoride by the child in his tooth formative years. Extrinsic stains, which are acquired by the consumption of certain food items like coffee or wine. Tobacco consumption also leads to extrinsic stains.
Tooth whitening procedures – Tooth whitening procedures at the dental office may include the use of bleaching agents or mild abrasive techniques. A well-qualified professional can judge the extent of discoloration of the tooth and can hence decide the method of tooth whitening required. Tooth whitening with bleaching agents can lead to sensitivity of teeth, so it should be done with caution and the use of tooth whitening toothpastes at home should be avoided because it can lead to serious consequences with time. As is already mentioned, every discoloration is not the same, so a patient should discuss about his/her treatment options with the dental professional.
