Braces are devices used to correct tooth misalignment or bite problems. They usually consist of a series of brackets, archwires, elastics, and other accessories, with the goal of gradually moving teeth into the correct position. The functions of braces include: 1. Adjusting tooth alignment Goal: Braces can correct problems such as crowding, large gaps, and misalignment of teeth to make them aligned. Method: By applying constant, gentle pressure, the teeth are pushed to move to a more appropriate position. 2. Improving bite problems Goal: Bite problems such as overbite (lower lower teeth), underbite (lower upper teeth), and crossbite (misaligned upper and lower teeth) can affect chewing function. Method: Braces can improve the bite relationship between the upper and lower teeth, ensure normal function, and reduce future oral problems. 3. Increase oral health Goal: Correct patients with irregular teeth and reduce the difficulty of cleaning teeth caused by crowding or misalignment of teeth, thereby reducing the risk of oral diseases such as caries and periodontal disease. How: Braces improve the alignment of teeth, making them easier to clean and less likely to harbor bacteria. 4. Improve facial aesthetics Goal: By improving the alignment and bite of teeth, braces can improve the appearance of the face, especially the proportion of teeth and lips. How: Improvements to teeth can often significantly improve the beauty and confidence of a smile. 5. Use different types Metal braces: The most common and most effective, usually consisting of metal brackets and archwires. Ceramic braces: Similar in color to teeth, less visible, but more expensive. Invisible braces: Such as Invisalign, use clear plastic brackets that gradually adjust the teeth by replacing them regularly. By wearing dental braces, patients are able to improve their bite and tooth alignment, ultimately achieving a healthier mouth and a more beautiful smile.
