The goal of orthodontics is not just to straighten teeth but also to ensure a proper, functional bite, which is achieved through a controlled, multi-step process. Braces work by applying gentle, constant pressure to stimulate the biological process of bone remodeling, allowing teeth to move slowly into new positions. The appearance of your teeth and braces will change significantly over time, sometimes looking worse before the final alignment is achieved.
The Phased Stages of Tooth Movement
Orthodontic treatment is a systematic journey that follows distinct, strategic phases. This methodical approach ensures that forces are applied gently and predictably, establishing a foundation for later, more complex movements.
The first phase is typically dedicated to leveling and alignment. During this stage, the orthodontist uses light, flexible archwires to correct severe crowding or rotation and bring the height of the teeth into a uniform plane. Because the wire conforms to the existing crooked teeth, the teeth may initially move in seemingly random directions or create temporary gaps as they untwist. This early movement creates a smooth arch shape, preparing for the next phase.
Once the teeth are generally aligned, the focus shifts to the working phase, which is dedicated to correcting the bite and closing any remaining spaces. This stage often involves the use of stronger, stiffer wires, along with auxiliaries like elastic bands or power chains, to move entire segments of the arch. Correcting an overbite or underbite requires the coordinated movement of the upper and lower jaws, which can temporarily make the bite feel uneven or awkward.
The final stage is known as finishing and detailing, where the orthodontist makes minor adjustments to achieve the ideal aesthetic and functional outcome. This involves ensuring that each tooth is perfectly positioned and that the cusps of the upper and lower teeth interlock correctly. Even small adjustments in tooth angulation or rotation can take several months, emphasizing the precision required at the end of treatment.
Why Brackets and Wires Appear Uneven
The appearance of crooked brackets or wavy wires is often an intentional part of the treatment plan, not a sign of a problem. The hardware is deliberately designed to apply specific forces to individual teeth. Each bracket acts as a handle to transmit force from the archwire, and its placement determines the direction of movement.
A bracket may be temporarily placed higher, lower, or at an angle on a severely rotated tooth to encourage it to spin into the correct orientation. As the tooth rotates, the bracket’s position will visually appear to straighten relative to the archwire. If all brackets were placed in a perfectly straight line on crooked teeth, the necessary rotational movements would not occur.
The initial archwires themselves are often bent or shaped to apply the precise torquing forces needed to untwist teeth. When inserted into the brackets, this wavy wire shape generates the gentle, persistent pressure that guides the teeth toward the desired straight arch. It is only later in treatment, when the teeth are closer to their final alignment, that the orthodontist will be able to place a perfectly straight, rigid wire.
Other features, such as elastic power chains or springs, also contribute to a temporary visual asymmetry. These components are used to pull specific teeth together to close gaps or to push teeth apart for space creation. The intentional unevenness of the hardware is a visual reflection of the complex, individualized mechanical forces being applied to achieve the final uniform alignment.
Identifying Normal Progress Versus Urgent Concerns
Distinguishing between expected sensations and genuine problems is important when managing life with braces. Normal progress involves mild soreness or tenderness, particularly after an adjustment, indicating that the teeth are actively moving. Minor irritations, such as a wire end poking the cheek, can usually be managed at home by applying orthodontic wax. Temporary gaps may appear as crowding is relieved, and teeth may feel slightly loose due to the necessary bone remodeling process. These minor shifts and discomforts are indications that the treatment is progressing as planned.
Urgent concerns require immediate attention from the orthodontist to prevent delays in treatment or injury. A loose or broken bracket means the force is no longer being applied correctly and needs to be re-bonded. Similarly, a wire that has come out of the back tube or is severely poking the gum tissue should be addressed promptly. Other emergencies include significant swelling of the face or gums, or any oral trauma resulting in broken hardware or severe pain.
To help prevent these issues, patients must avoid hard, sticky, or crunchy foods that can shear off brackets or bend wires. Regular, diligent oral hygiene is also necessary to prevent plaque buildup, which can hinder movement and damage the teeth.
