Invisalign Clear Aligners vs. Traditional Fixed Braces
Two proven ways to straighten your teeth, compared side by side — so you know what to expect before your free assessment.
Both straighten teeth, but they work very differently day to day — one is removable and nearly invisible, the other is fixed and works around the clock. Here's how they compare.
| Invisalign clear aligners | Traditional fixed braces | |
|---|---|---|
| Primary mechanism | Custom, 3D-printed medical-grade clear plastic aligners, changed every 1–2 weeks. | Metal or tooth-coloured ceramic brackets glued to the teeth, connected by archwires. |
| Visible when worn? | No — nearly invisible, and highly discreet for working professionals and public-facing roles. | Yes — noticeable metal wires and brackets (ceramic options blend in better but are still visible). |
| Removable for eating and cleaning? | Yes — fully removable to eat, drink, brush and floss, with no food restrictions. | No — fixed in place; hard, sticky or chewy foods risk snapping a wire. |
| Oral hygiene and maintenance | Straightforward — brush and floss naturally, with no brackets in the way. | Needs extra care — special floss threaders or interdental brushes to clean around the wires. |
| Comfort and mouth sensitivity | Smooth plastic, gentle on lips and cheeks, with minimal risk of mouth sores. | Metal edges or wire ends can irritate soft tissue and may need orthodontic wax. |
| Compliance required | High — needs 20–22 hours of daily wear to stay effective. | None day-to-day — works continuously, 24/7, once fitted. |
| Clinical suitability | Best for mild to moderate crowding, spacing and bite adjustments. | Suitable for all cases, including severe misalignments, complex rotations or vertical moves. |
| Check-up frequency | Routine reviews every 6 to 8 weeks, with fewer emergency appointments. | Adjustment and tightening appointments every 4 to 6 weeks. |
| Average duration | Typically 6 to 18 months, depending on case complexity and wear time. | Typically 12 to 24 months. |
General guidance only — which option suits you depends on the complexity of your case. A free assessment gives you a straight, personal recommendation.
