How do braces work is one of the first questions patients ask when a dentist suggests orthodontic treatment, and the answer is more interesting than you might expect. Braces do not force teeth into place overnight. They use steady, gentle force to guide your teeth, and even the bone that holds them, into a new position over time.
This guide walks through how dental braces work, the parts that do the work, the main types available, and what to expect if you wear braces. Whether you are considering braces for yourself or your child, knowing the basics makes the whole process easier to follow. By the end, how braces gradually move teeth into place should be clear.
Quick Overview
- Braces work by applying constant, gentle pressure that moves your teeth slowly into a straighter position.
- That pressure triggers a natural process called bone remodelling, where the bone around each tooth breaks down and rebuilds.
- Brackets, an archwire and small elastic bands work together to guide teeth in a specific direction.
- Treatment takes time and regular adjustments, and results depend on your teeth, your jaw and your age.
Below, we explain the mechanism step by step, the parts of a set of braces, the main types, and how to care for them.
How do braces work?
Braces work by exerting constant pressure on your teeth. Held by brackets and a connecting archwire, that gentle, steady force slowly moves teeth from a crooked or crowded position toward a straighter one, correcting many bite problems along the way.
The movement is gradual by design. Teeth are not set rigidly in your jaw; each one sits in bone and is held by soft tissue that allows tiny movements. When braces apply pressure in a specific direction, your teeth begin to shift a little at a time, and the bone around them adapts to match. This is why orthodontic treatment is measured in months rather than days, and why the force involved is applied gradually rather than all at once. Too much force too quickly would not speed things up; it could harm the tooth and the surrounding bone, so a measured, ongoing push is what actually works.
What problems can braces fix?
Braces are used to correct a wide range of orthodontic issues, not just the look of your smile. They can bring crowded teeth into line, close one or more gaps, and rotate or straighten crooked and misaligned teeth so they sit in a straight line.
Braces also address bite issues, such as an overbite, underbite or crossbite, where the upper and lower teeth do not meet as they should. Because the way your teeth meet is linked to your jaw, correcting these bite problems can also improve your overall jaw alignment. The aim is straight teeth that not only look tidier but also work and clean more easily, which is good for your long-term oral health.
The parts of a set of braces
Traditional braces are made of three main parts: small brackets bonded to each tooth, a thin archwire that runs across them, and elastic bands that hold everything together. Each part has a job in moving your teeth.
Metal brackets are fixed to your individual teeth and act as handles. The archwire, often made of nickel titanium or stainless steel, threads through the brackets and carries the force that moves your teeth. Small elastic bands, sometimes called rubber bands, hold the archwire in place and can add extra pull, sometimes connecting your upper and lower teeth to correct the bite. As the wire tries to return to its natural shape, it applies pressure to the teeth through the brackets. That is how braces hold their shape and keep working between your visits.
What happens to your teeth and bone
When braces apply pressure, each tooth presses against the bone on one side and pulls away on the other. Your body responds by removing bone where the tooth is heading and building new bone behind it, a process called bone remodelling.
Around every tooth is a layer of underlying tissue that connects it to the bone. Pressure from the braces stretches this soft tissue on one side and compresses it on the other. On the compressed side, your body breaks down bone so the tooth can move; on the stretched side, it lays down new bone to fill the space left behind. This steady cycle is how teeth are moved safely, and it is why teeth move slowly rather than all at once. This gradual tooth movement continues, adjustment after adjustment, until each tooth reaches its desired position, and the teeth moved during treatment stay supported by healthy bone. How quickly it happens varies from person to person, shaped by your individual biology and how closely you follow your plan. It is also completely normal for teeth to feel slightly loose while this is happening, which settles as the bone firms up around each tooth’s new position.
Types of braces
The main types are traditional metal braces, ceramic braces and lingual braces, plus clear aligners as a removable alternative. They rely on the same principle of gentle pressure but differ in how they look, where they sit and what they cost.
Traditional metal braces
Traditional metal braces use hard-wearing stainless steel brackets and are the most common option, well suited to more complex movements.
Ceramic braces
Ceramic braces work in the same way as metal braces but use tooth-coloured brackets that blend in and are less noticeable.
Lingual braces
Lingual braces sit on the inside of your teeth, facing the tongue, so they stay hidden from view while they straighten teeth.
Clear aligners
Clear aligners, such as Invisalign, are a series of removable clear trays that move teeth without brackets or wires, and can suit milder crowding or spacing.
Your dentist will talk through which option suits your teeth, your lifestyle and your goals.
What to expect during braces treatment
Braces treatment is a gradual process. After your braces are fitted, you return for regular adjustments, where your dentist tightens or changes the archwire to apply new pressure and fine-tune the position of your teeth.
Getting your braces fitted
Getting braces fitted usually takes about one to two hours, and involves cleaning each tooth, bonding on the brackets, and threading the archwire through them. Both braces and clear aligners should be fitted and monitored by a dentist, who will check your teeth and plan the treatment before anything begins.
Adjustments along the way
Each visit builds on the last. You will usually return every few weeks, and at your next appointment the wire may be adjusted or replaced so your teeth keep moving in the right direction, with elastics added for fine-tuning. Braces keep working between visits by applying constant pressure, so your teeth move steadily even when nothing feels like it is happening. Treatment time varies from person to person, and some orthodontic cases need longer than others depending on how much movement is needed, which is something your dentist can estimate for you. Keeping your appointments helps the whole treatment process stay on track.
Looking after your braces
Braces need a little extra care. Brush gently after meals with a soft-bristled toothbrush and fluoride toothpaste, clean between your teeth, and protect your oral health throughout treatment.
Food traps easily around brackets and wires, so thorough cleaning matters more than ever. Take your time around each bracket, and clean between the teeth where a normal brush cannot reach. Interdental brushes or a floss threader help you clean under the wire and between teeth, and rinsing after meals clears trapped food. Brackets and wires trap more food and plaque than usual, so staying on top of cleaning helps you avoid decay and gum problems during treatment. Keeping up regular dental visits protects your teeth and gums while your braces do their work, and good habits now make your result easier to keep afterwards.

Frequently Asked Questions
Do braces hurt?
Braces should not be uncomfortable for long, but it is common to feel some tenderness or tightness for a few days after they are fitted and after each adjustment. This happens as your teeth begin to move and usually eases on its own. If discomfort is ongoing or sharp, let your dentist know so they can check everything is sitting correctly.
How long does braces treatment take?
Most braces treatment takes somewhere between one and three years, though this varies widely. The time depends on how much your teeth need to move, the type of braces, and how closely you follow your dentist’s advice. Your dentist can give you a clearer estimate once they have assessed your teeth and jaw.
Can adults get braces, or are they only for children?
Adults can get braces too. While younger patients are often treated because their jaws are still developing, teeth can be moved at almost any age, provided your gums and supporting bone are healthy. Many other patients start treatment well into adulthood, which is why discreet options like ceramic and lingual braces have become popular.
Which foods should I avoid with braces?
With fixed braces, it helps to avoid hard, crunchy and sticky foods that can damage a bracket or wire, such as hard lollies, nuts and chewing gum. Cutting firmer foods into smaller pieces also reduces the strain on your braces. Your dentist will give you a list of certain foods to be careful with during treatment.
What happens when my braces come off?
Once your teeth have reached their new position, your braces are removed, and you move on to wearing a retainer. Teeth naturally tend to drift over time, so a retainer holds them in place while the bone settles. Your dentist will explain how long to wear it to protect your result.
