This is a specialized area in dentistry focusing in how teeth are to be aligned straight inside the mouth. A beautiful smile comprises of healthy gum, bright white teeth and straight teeth. Some people have too many teeth or too big in size of the teeth to fit perfectly inside the mouth, while others have gaps between teeth. Orthodontists or dentists with further training in orthodontics can implement braces to straighten teeth. Traditional braces normally required placing metal brackets and wires onto teeth and treatment length often involves 2-4 years time. In recent years, some shortcut options are made available to people such as Invisalign braces or often called invisible braces. I advise that pros and cons of each option should be reviewed together with your dental professional before you choose what option to go for.
