Justin Bieber does not have a gold tooth.
He has, however, been seen sporting various grillz over the years. Grillz are removable dental jewelry that are typically made of gold, platinum, or diamonds. They are often worn for fashion purposes and can be customized with different designs.
It is important to note that while grillz are a popular fashion accessory, they can also pose certain risks to dental health. For example, they can trap food and bacteria, leading to cavities and gum disease. They can also damage the enamel of teeth if they are not properly fitted.
Therefore, if you are considering getting grillz, it is important to consult with a dentist to ensure that they are safe for your teeth.
