“Buck teeth,” the common term for protruding upper front teeth, is medically referred to as a malocclusion, often an excessive overjet or a Class II malocclusion. This condition occurs when the upper teeth extend significantly forward past the lower teeth, resulting from misaligned teeth or a mismatch in jaw size. While correction is often addressed during childhood, effective treatment options are available to adults seeking to improve their bite function and aesthetic appearance. The adult process differs because the jawbones are fully formed, meaning tooth movement is achieved through remodeling of dense bone rather than leveraging natural growth.
Non-Surgical Orthodontic Solutions
Most adult corrections for protruding teeth utilize orthodontic mechanics to physically reposition the teeth and align the bite. These methods apply continuous, gentle force, which gradually encourages the surrounding bone tissue to remodel, allowing the teeth to shift into a corrected position. The duration for this process typically spans between 18 to 36 months, depending on the severity of the initial misalignment and the complexity of the case.
Traditional metal or ceramic braces involve brackets bonded to the teeth and connected by archwires, providing precise control over individual tooth movement. Clear aligner systems, such as Invisalign, offer a nearly invisible alternative, using a series of custom-made, removable plastic trays to incrementally move the teeth. While effective for mild to moderate cases, clear aligners require significant patient compliance, needing to be worn for 20 to 22 hours per day.
For more challenging movements, orthodontists may incorporate adjunct therapies to enhance the efficiency of braces or aligners. Intermaxillary elastics, commonly known as rubber bands, are stretched between the upper and lower arches to help correct the bite relationship. Temporary Anchorage Devices (TADs) are small, temporary screws placed into the jawbone that act as fixed points to help pull or push teeth more effectively.
Aesthetic and Camouflage Treatments
When protrusion is mild or the primary concern is purely cosmetic, non-orthodontic options can camouflage the appearance of buck teeth without fundamentally changing the underlying bite structure. These treatments alter the shape and surface of the teeth to create an illusion of better alignment. They are generally quicker alternatives to full orthodontic treatment.
Dental bonding involves applying a tooth-colored composite resin directly to the tooth surface, which is then sculpted and hardened with a special light. This material can be used to add volume to teeth that appear too small or to reshape the edges of teeth that contribute to the protruded look. Bonding is a minimally invasive, single-visit procedure that is more economical than other cosmetic approaches.
Porcelain veneers represent a more durable aesthetic solution, consisting of thin, custom-made shells bonded to the front surface of the teeth. Veneers are often used to correct minor spacing, chips, or irregularities in shape and can visually mask slight protrusion. Unlike bonding, veneers typically require a small amount of enamel removal to ensure a proper fit and a natural appearance.
Addressing Severe Skeletal Issues
In some cases, the protrusion is not solely due to the position of the teeth but is a skeletal issue, meaning the upper or lower jawbones are severely mismatched in size or position. This condition, often a severe skeletal Class II malocclusion, cannot be fully corrected by moving teeth alone without compromising stability or facial aesthetics.
The definitive treatment for significant skeletal discrepancies is a combined approach known as surgical orthodontics, which involves orthognathic (jaw) surgery. This process requires an initial phase of orthodontics to align the teeth within each jawbone individually, a step called decompensation. The surgery then involves repositioning the jaws, often by advancing the lower jaw (mandibular advancement), to establish a proper bite relationship.
Following the surgical phase, a final period of orthodontic treatment is necessary to fine-tune the occlusion and ensure the teeth interdigitate perfectly. This comprehensive treatment is typically reserved for adults who experience functional impairments, such as difficulty chewing or speaking. The entire process, including pre- and post-surgical orthodontics, is a multi-year commitment.
Retention and Long-Term Stability
Regardless of the method used, the teeth possess a natural tendency to drift back toward their original positions, a phenomenon known as relapse. The retention phase is a lifelong commitment and is important to ensure the stability of the corrected bite. The surrounding bone, ligaments, and gums need time to reorganize and stabilize around the newly positioned roots.
Retainers are custom-made appliances designed to hold the teeth in their final alignment until biological stabilization occurs. There are two primary types: fixed and removable. Fixed retainers consist of a thin wire permanently bonded to the backside of the front teeth, offering continuous retention.
Removable retainers include clear thermoplastic trays, which resemble aligners, or traditional Hawley retainers, made of acrylic and wire. The initial wear protocol typically involves wearing the retainer full-time for several months, followed by a transition to nightly wear indefinitely. Consistent use is paramount to maintaining the aesthetic and functional results achieved.
