Tongue and lip piercings, tooth jewels and even gold grills all give us the chance to accessorise our mouths.
But again, these fancy things need to be looked after carefully to avoid long term damage to our teeth and gums.
Oral piercings
Oral piercings can pose a bigger risk to your health than piercings on other parts of the body.
This is because they are difficult to care for and are more prone to infection.

Tooth jewellery
Tooth jewellery involves sticking gemstones to your tooth but, pretty as it might look, it can lead to some long-term problems.
The area of the tooth underneath the gem is impossible to clean and can become damaged.
It's also illegal for anyone who is not a qualified dentist to carry out the application of tooth jewellery because of the risk of damage to your teeth.
Teeth grills / grillz
By wearing tooth grills you might increase your risk of tooth decay and gum disease. This is because bacterial plaque can get trapped between them and the tooth's surface.
They can interfere with your bite, making it difficult to close your mouth properly. They can also cause headaches and pain from propping the mouth open in an unnatural position.
