Introduction to Orthodontics
Orthodontics is the branch of dentistry that focuses on correcting the alignment of teeth and making sure they are properly positioned in your jaw. An orthodontist specialises in treatments that help straighten your teeth, such as braces or dental retainers. Both of these methods use consistent, gentle pressure to gradually guide teeth into position.
Orthodontics can be used to treat a range of different dental problems. Some of the most common include crooked or crowded teeth, over or under bites caused by misaligned jaws, irregular positioning or gaps in your teeth. Orthodontics may also look after issues caused by dental diseases like decay or gum disease, or dental injuries & accidents.
