Clear aligners straighten teeth by applying controlled, strategic pressure to move them gradually into alignment. Each aligner set makes slight adjustments, guiding teeth into their next position based on a dentist-designed treatment plan.
Understanding how clear aligners actually work helps you trust the process and stick with the treatment. Teeth don’t move at random — they respond to mechanical force applied in a precise, biological way. When aligners are designed and monitored correctly, the results are predictable, safe, and long-lasting.
Modern aligner treatments start with detailed scans or impressions. These models form the foundation of your dentist-directed plan.
With NewSmile, the process includes:
This digital planning stage ensures that every shift is both safe and biomechanically appropriate.
Each aligner tray applies gentle force to certain teeth, encouraging them to shift horizontally, vertically, or rotationally.
Aligner pressure doesn’t push teeth instantly — it stimulates bone remodeling, a natural biological response.
Teeth move because the bone around them adapts. When gentle force is applied, the body breaks down bone on one side and rebuilds it on the other. This is called alveolar bone remodeling.
This process is slow, steady, and completely natural — one of orthodontics’ core principles.
Clear aligner success relies on consistent wear. Each tray slightly advances your teeth toward their final position. This is why following the recommended 22-hour wear schedule is essential.
With systems like NewSmile available across the U.S., you can access dentist-designed plans with optional virtual support to ensure every step is on track.
You're an excellent candidate if you:
Most U.S. adults and teens qualify, making aligners one of the most accessible orthodontic treatments available.
Most teeth can be moved depending on your treatment plan, including rotations and minor bite corrections.
Mild pressure is normal when switching trays — it means movement is happening.
Most treatments last 4–12 months depending on case complexity.
Mild overbite, crossbite, and underbite issues may be treated depending on severity.
Yes. They use gentle orthodontic forces used in traditional braces — just delivered in a more discreet form.
