Beautiful and healthy smile is a straight way towards well-being, good mood and self-confidence. Unfortunately, many people feel embarrassed because of their discoloured, yellowish teeth therefore they tend to cover their mouth with hand when laughing, avoid close contact with people, and avoid showing their teeth when smiling.

Changes in tooth colour are caused by several factors: poor oral hygiene; genes; passing time (with age, the structure of teeth changes – dentin thickness increases, the colour turns yellow and the enamel becomes thinner and more transparent); consumption of staining foods (coffee, black tea, red wine), harmful habits (smoking, chewing tobacco), as well as various diseases or administration of antibiotics and other medications.
