Invisalign vs. Braces - Which is Best? Each alignment method has its advantages and disadvantages. In general, braces are cheaper and are a time-tested and successful solution. But they are not removable and brushing and flossing are a bit more complicated. And braces are effective for severely misaligned teeth. Invisalign aligners are clear and offer a more appealing cosmetic appearance. They are worn almost 24 hours per day and they are usually the more expensive option. Because they require additional care and cleaning Invisalign aligners are usually not recommended for younger children.
