Of all the braces, aligners, are the most aesthetically pleasing. They are invisible and can be removed before eating or brushing your teeth. They are comfortable and easier to clean. Aligners may cost more than traditional metal or ceramic braces. They are not suitable for severely crowded or misaligned teeth.
After having braces on for a year or two, you may have stains around the brackets. That is the reason it is so important to clean your teeth properly when you have braces.
