If you have crooked or gapped teeth, you may be tempted to try DIY orthodontics using videos on YouTube or at-home kits that are advertised on TV. These options are said to save people money by avoiding appointments with dental professionals. The truth is, DIY orthodontics are unsafe and could end up costing you more money later on. Complications can arise from placing DIY or mail-order dental appliances over decayed teeth or infected gums. Only a professional orthodontist can determine the presence of these problems and ensure they are fixed correctly. Options like Invisalign 5 offer people with mildly crooked or gapped teeth a way to straighten them with clear aligners instead of braces, in as little as six to eight weeks, at a cost comparable to those mail-order products.
