Teeth colour is created by a number of factors; what you eat, how often you brush, and the colour of your parents’ teeth all effect how yours turn out.
There can also be staining on your teeth. It is quite common with smokers and people who drink coffee, tea, or sodas. Food can also have an impact, from curries to chocolate. The more a product would stain a shirt the more it will stain your teeth.
Make sure you’re following the 2×2 rule. Brush for at least two minutes, twice a day, and use a pea-sized amount of toothpaste. When picking your mouthrinse be sure it has enough fluoride – the recommended amount is between 0.05% to 0.2% sodium fluoride.
From yellow to grey, your teeth can come in many shades. This is due to the fact that the interior of your tooth, called the dentin, is where the colour comes from. As light filters though the tooth the hue is changed.
