At Perfect White Smile Cosmetic Dentistry Beverly Hills, led by Dr. David Frey, we frequently meet patients from Beverly Hills, West Los Angeles, and across Greater Los Angeles who are researching jaw expansion devices such as DNA Vivos, ALF and AGGA. Many of these appliances are promoted as “non-surgical” ways to widen the jaw, improve breathing and sleep, and relieve TMJ symptoms.
While these claims can sound appealing, it’s important to understand how these devices actually work, what science supports, and what risks may be involved before starting treatment.
This guide explains DNA Vivos, ALF and AGGA appliances from an evidence-based cosmetic and functional dentistry perspective.
Understanding DNA Vivos, ALF and AGGA Appliances
What is the DNA Vivos Appliance?
The Vivos DNA Appliance® (Daytime-Nighttime Appliance) is a custom-fabricated, removable oral orthopedic device designed to promote gradual expansion and remodeling of the maxilla (upper jaw) in both developing and adult patients. Worn primarily in the evening and during sleep, the appliance applies light, intermittent forces through precision expansion screws and acrylic support structures to encourage slow transverse widening of the dental arches and midface. Unlike traditional rapid palatal expanders that rely on fixed anchorage, the DNA appliance is tooth-borne and removable, allowing controlled, progressive adjustment over time. It is commonly used in airway-focused dentistry to increase arch width, improve oral cavity volume, and support better nasal breathing and upper airway development as part of a non-surgical treatment approach.
What Is the ALF Appliance?
The Advanced Lightwire Functional (ALF) appliance is a thin wire device placed behind the teeth along the palate. It delivers light, continuous pressure and is often marketed as a way to “guide” jaw growth and improve craniofacial balance.
ALF is most promoted for children and adolescents, though some providers offer it to adults. Training for ALF is typically provided through certification programs rather than formal orthodontic residencies.
Supporters claim that ALF can influence facial structure, posture, and airway health. However, these claims are not strongly supported by high-quality clinical research, particularly in adults.
What Is the AGGA Appliance?
The Anterior Growth Guidance Appliance (AGGA), also known as ORA, is a device that includes wires, springs, and an acrylic pad that rests against the palate. It applies forward and outward pressure on the front teeth.
AGGA can be used to stimulate upper jaw growth in adults. Unlike traditional orthodontic expanders, it relies mainly on tooth-supported forces rather than skeletal anchorage.
AGGA has been the subject of significant medical, legal, and regulatory scrutiny due to reports of patient harm.
How the DNA Vivos, ALF and AGGA Compare to Traditional Orthodontic Devices
Many patients are surprised to learn that ALF and AGGA function similarly to long-established orthodontic appliances such as:
- Crozat appliances
- Quad-helix expanders
These devices have been used for decades to move teeth and create dental space. However, they are not designed to produce skeletal expansion of the jaw in adults.
In traditional orthodontics, these appliances are used cautiously and within clearly defined limits. They are not promoted as tools for facial remodeling or adult jaw growth.
In fact, none of the 3 above mentioned appliances may actually grow any bone! A dentist super-imposed over 100 cat scans before and after only to find that no growth occurred in any of them. Yes, this is a simple case study but many patients go through hell with devices only to wind up in a worse jaw position or no change whatsoever.
Dental Expansion vs. Skeletal Expansion: A Critical Difference
One of the most important concepts in jaw treatment is understanding the difference between dental and skeletal expansion.
Dental Expansion
Dental expansion occurs when teeth are tilted or moved outward within the jawbone. This can help with mild crowding and spacing issues.
However, excessive dental expansion can:
- Push teeth outside their supporting bone
- Cause gum recession
- Lead to bone loss
- Create bite instability
- Increase tooth sensitivity
Dental expansion does not physically widen the jawbone since the teeth tip to create space.
Skeletal Expansion
Skeletal expansion means widening the actual jawbone by separating the midpalatal suture.
In children and adolescents, this can be achieved using orthopedic expanders such as:
- Rapid Palatal Expanders (RPE/RME)
- Hyrax expanders
- Haas expanders
In adults, the palatal suture is fused. True skeletal expansion typically requires:
- Surgically Assisted Rapid Palatal Expansion (SARPE)
- MARPE or MSE devices with skeletal anchorage
Without these approaches, meaningful jaw widening in adults is limited.
Does the DNA Vivos, ALF and AGGA Create Real Jaw Expansion?
DNA Vivos, ALF and Skeletal Change
Research suggests that ALF produces primarily dental movement rather than bone separation. The forces it applies are generally too light to open the palatal suture in adolescents and adults.
Any “widening” seen is most likely caused by tooth tipping, not true jaw expansion.
AGGA and Jaw Growth Claims
Clinical analyses indicate that AGGA also works mainly by pushing teeth forward and outward.
In many documented cases, this has resulted in:
- Severe tooth flaring
- Bone erosion
- Gum recession
- Tooth mobility
- Tooth loss
There is no strong scientific evidence that AGGA reliably produces safe skeletal expansion in adults. It just tips the anterior 6 teeth forward creating space in the alveolar ridge bone.
Potential Risks of DNA Vivos, ALF and AGGA Treatment
At our Beverly Hills cosmetic dentistry practice, patient safety and long-term stability are priorities. Devices that rely mainly on dental tipping when skeletal correction is needed can create serious complications.
Possible risks include:
- Teeth moving outside the bone
- Permanent gum recession
- Exposed tooth roots
- Chronic facial or jaw pain
- Bite deterioration
- Chewing difficulties
- Root damage
- Need for future surgery or extractions
- Treatment relapse
When structural jaw issues are present, using inappropriate appliances can cause more damage.
Legal and Regulatory Concerns
In recent years, AGGA and similar appliances have been linked to lawsuits and FDA safety communications. Cases allege that patients were harmed after being told the devices would remodel their jaws. The jury is still out if any expansion occurs with bone growth.
Reported outcomes include:
- Loss of multiple teeth
- Permanent bone damage
- Extensive restorative treatment
- Ongoing pain and dysfunction
These cases highlight why evidence-based dentistry is essential, especially for treatments that promise dramatic changes.

- MARPE or surgical consultation
- Restorative and cosmetic solutions
- TMJ-focused therapy
Every treatment plan is personalized for patients in Beverly Hills, West Los Angeles, and the surrounding communities.
Frequently Asked Questions (FAQ) About DNA Vivos, ALF, AGGA, and Jaw Expansion Devices
Can ALF expand my jaw as an adult?
In most adults, ALF does not produce true jaw expansion. It moves teeth rather than widening bone.
Is AGGA safe for adults?
AGGA has been associated with serious complications in many cases. It is currently considered controversial and high-risk. Its too bad because if used properly, it helps with orthodontics especially with crowded teeth in the anterior segment.
Can jaw expansion improve breathing?
In some patients, properly planned skeletal expansion may improve airway volume. However, this requires precise diagnosis and appropriate appliances or surgery.
How do I know what treatment is right for me?
A comprehensive evaluation with imaging and expert analysis is essential. One-size-fits-all appliances are rarely appropriate. In most cases, everything can be accomplished with Controlled Arch Braces. The wires are trained to move the teeth out.
Do you treat TMJ and bite issues in Los Angeles?
Yes. Dr. Frey provides TMJ, bite alignment, and cosmetic-functional dentistry services for patients.

- Scientific evidence does not support reliable skeletal expansion in adults using these devices.
- Both appliances mainly cause tooth movement rather than bone growth.
- Improper use may result in permanent damage.
- Evidence-based orthodontic and cosmetic dentistry offers safer, more predictable outcomes.
