Having beautiful white teeth of course depends on good oral hygiene to a degree. But brushing and flossing alone aren’t the only factors. The structural integrity of our tooth enamel is actually determined by genetics, meaning some of us are more likely to experience decay than others. 

The same goes for dentine, which is the calcified tissue that lies underneath tooth enamel, protecting the dental pulp encased within. Now dentine is actually yellow, which explains why our teeth gradually turn that colour when the enamel wears away.
