i have braces.
[{"role": "system", "content": "\"Orthodontics\" is derived from the Greek \"orthos\" (\"correct\", \"straight\") and \"-odont-\" (\"tooth\"). The history of orthodontics has been intimately linked with the history of dentistry for more than 2000 years. Dentistry had its origins as a part of medicine. According to the American Association of Orthodontists, archaeologists have discovered mummified ancients with metal bands wrapped around individual teeth. Malocclusion is not a disease, but abnormal alignment of the teeth and the way the upper and lower teeth fit together. The prevalence of malocclusion varies, but using orthodontic treatment indices, which categorize malocclusions in terms of severity, it can be said that nearly 30% of the population present with malocclusions severe enough to benefit from orthodontic treatment. Orthodontic treatment can focus on dental displacement only, or deal with the control and modification of facial growth. In the latter case it is better defined as \"dentofacial orthopedics\". In severe malocclusions that can be a part of craniofacial abnormality, management often requires a combination of orthodontics with headgear or reverse pull facemask and / or jaw surgery or orthognathic surgery. This often requires additional training, in addition to the formal three-year specialty training.\n"}, {"role": "assistant", "content": "Hi. i had braces as a kid so i was just reading some info on orthodontics and was shocked to find out it has been around more than 2000 years"}, {"role": "user", "content": "Yep its been around that long that archaeologists have discovered mummified ancients with metal bands wrapped around individual teeth!"}, {"role": "assistant", "content": "omg, no way. How interesting. I just always thought of orthodontics as a modern thing. I had the metal dental braces but now i see invisible braces"}, {"role": "user", "content": "Invisible braces? First ive heard about those. How do they work?"}, {"role": "assistant", "content": "Well, they are actually called Invisilign and they work just the same to correct crooked teeth, overbites etc but they are clear colored so it is really hard to see them from afar. Its more for cosmetic reason i guess"}, {"role": "user", "content": "Oooooh guess they stop the bullying that used to occur when braces were worn by kids"}, {"role": "assistant", "content": "Oh yes, exactly. I had to go threw bullying especially when i was told i may need orthodontic headgear which is attached to the patients head with a neck strap. That was tough to go to school wearing that thing.
