Ever wondered how a thin wire and a few small brackets can actually move teeth? The short answer: gentle pressure, kept up over time, in a direction your dentist has planned. Here is what is really going on, part by part.
The biology
Your teeth are not fused to the jawbone. Each one sits in its own socket, cushioned and held by a thin band of fibres called the periodontal ligament. That ligament is what makes movement possible.
This is a natural, everyday process. It just takes time. In most people a tooth moves roughly one millimetre a month, which is why treatment is measured in months rather than weeks. Pushing harder does not move a tooth faster, it only makes it sore.
The hardware
A fixed brace looks complicated, but it is really only four things working together.
Stage by stage
Braces do not do everything at once. The work is ordered, and each stage sets up the one after it.
Crooked teeth start lining up into a proper arch. A thin, springy wire does most of the work here. This is the stage where you notice the biggest visible change.
Gaps, including any left behind by extractions, are closed bit by bit using a firmer wire with small springs or elastics.
Each tooth is adjusted so the upper and lower sets meet properly. The changes are small, but they matter for chewing and for long-term stability.
Once the braces come off, a retainer holds everything in its new position while the bone settles around it. This part is not optional. Teeth drift back if the retainer stays in the drawer.
The retainer is included in both of our braces payment plans, along with extractions if you need them, scaling, and rebonding if a bracket comes off. See pricing for full details.
Every 4 to 6 weeks
The appointment is usually short, often 20 to 30 minutes. This is the normal order of things.
Once the new wire is in, the pressure builds again and the teeth start moving. That pressure fades over the following weeks, which is exactly why the visits are spaced the way they are. Miss appointments and the movement simply stalls, so turning up is honestly the biggest thing you can do to keep treatment on track.
It is normal for teeth to feel tender or a little achy for two or three days after an adjustment. Soft food helps. If something is sharp, poking your cheek, or genuinely painful, call the clinic instead of waiting for the next appointment.
How long
Most cases run 18 to 24 months. Mild overcrowding can be quicker. Complicated bites take longer. The table below shows a typical pattern, not a promise.
| Stage | Typical duration | What you notice |
|---|---|---|
| Early alignment | 3 to 6 months | The fastest visible change |
| Closing the spaces | 6 to 12 months | Gaps shrink slowly, month by month |
| Fine-tuning the bite | 3 to 6 months | Small changes, the bite starts to feel right |
| Retainer | Long term, after the braces come off | Worn as instructed to hold the position |
Every case is different, and no dentist can name an exact finish date at the start. Age, how far the teeth need to travel, whether extractions are needed, gum health and how consistently you attend all shift the timeline. Your dentist will give you an honest estimate after examining your teeth and X-rays, not before.
