Braces are sometimes necessary to align crooked teeth, correct a misaligned bite or modify the amount of space between teeth, but many patients dislike the idea of wearing them. However, that dislike often partly stems from the fact that people aren't aware of more modern orthodontic options, such as self-ligating braces. As with traditional braces, self-ligating braces fit small brackets to your teeth which are connected to a thin wire. That wire is used to apply force, which is what moves your teeth into the correct position.

Untreated tooth decay can lead to dark spots on your teeth, which are cavities. Once a dentist has filled those cavities (using a tooth-coloured composite dental resin), your teeth have been restored. So why, potentially years later, are you developing yellow spots on your teeth? Enamel and Fillings The outer layer of human teeth is made of dental enamel, which is highly mineralised and incredibly strong. However, when this enamel decays, your dentist will fill any cavities with composite resin, which is designed to match the colour of your dental enamel.
