Chapter 18: The Retention Phase
Comprehensive treatment doesn't end the day braces come off or the last aligner is worn. Teeth remain capable of shifting for a long time afterward, so a period of retainer wear is a standard and necessary part of the process, not an optional add-on.
Types of Retainers
• Hawley retainers: a removable retainer with a wire and acrylic base, adjustable and durable, often used as a first retainer after braces or aligners.
• Clear (Essex-type) retainers: a removable, transparent plastic tray similar in appearance to a clear aligner, popular for its near-invisibility.
• Fixed (bonded) retainers: a thin wire bonded directly to the back of the front teeth, worn continuously and not removed by the patient, often used alongside a removable retainer on the opposite arch.
Typical Wear Schedule
Most orthodontists recommend near full-time wear (aside from eating and cleaning) for the first few months after active treatment ends, gradually reducing to nights-only wear, often continued indefinitely or for several years, since teeth can drift at any age without some form of ongoing retention.
Skipping the retention phase is one of the most common and most avoidable causes of relapse — teeth gradually shifting back toward their original position after otherwise successful treatment.
