The length of time needed for braces depends on a case-by-case basic. Typically, patients will wear fixed braces for about 18 to 24 months. For oral issues that are more challenging to correct or for our older patients, braces may be required for up to three years. If your dental problems are less severe or you’re a prime candidate for clear aligners like Invisalign, braces may only be needed for 6 to 12 months.
