Braces help make teeth straight.
They use small parts to push teeth. This helps your teeth fit well.
Metal parts called brackets stick to the teeth. A wire goes through the brackets. Tiny rubber bands hold the wire in place. These bands can be many colors.
The wire puts pressure on the teeth. This pressure moves the teeth slowly. New bone grows to hold the teeth in their new spots. This keeps the teeth safe and strong.
Some braces are clear so they are hard to see. Other braces go behind the teeth. You can even use clear trays to move teeth. These trays are called aligners.
After the braces come off, you may wear a clear plate. This plate is called a retainer. It keeps your teeth from moving back. It helps your new smile stay straight.
Braces help make teeth straight. They also help teeth fit together well.
This can fix gaps or crooked teeth. It can also help with how a person bites.
How do braces work? They use force and pressure to move teeth. First, a doctor sticks small metal parts called brackets to the teeth. Then, a wire goes through these brackets. Small rubber bands, called ligatures, hold the wire in place.
The wire puts pressure on the teeth. This pressure moves the teeth slowly. As the teeth move, the body uses bone remodelling. This is a way the body makes new bone to support the teeth in their new spots.
There are many kinds of braces. Some are made of metal. Others are clear so people can barely see them. Some braces go behind the teeth. After the braces come off, people often wear a retainer. A retainer is a clear plate. It keeps the teeth from moving back to their old spots.
Dental braces are special tools used to straighten teeth. They help teeth fit together in a healthy way.
Braces can fix many different issues. They can fix gaps or crooked teeth. They also help with things like overbites, underbites, or cross bites. Some people use braces to improve how their jaw works. Others use them just to make their smile look better.
Braces can be used for health or for looks.
How do these tools actually move your teeth? It happens through constant force and pressure.
First, a doctor attaches small pieces called brackets to each tooth. Then, a metal wire called an archwire is placed through the brackets. Small elastic bands, or ligatures, hold the wire in place. The wire pushes against the brackets to move the teeth. This pressure causes a process called bone remodelling. The body actually makes new bone to support the teeth in their new spots. This must happen slowly so the teeth stay safe.
Getting braces is a careful process done by a trained doctor. In North America, most people see an orthodontist. These are dentists who spent two or three extra years studying how to fix teeth and jaws.
First, the doctor looks at your teeth and takes X-rays. They might even make a 3D digital model of your mouth using a laser scanner. If you need space for your teeth, the doctor might use spacers to move teeth apart. They might also use an expander to make the dental arch wider. Sometimes, a doctor may even need to remove a tooth to make room.
There are many different types of braces you might see. Traditional metal braces are very common and use stainless steel.
Some people have allergies to nickel, so they might use gold-plated steel or titanium instead. Titanium is light and very strong. There are also self-ligating braces that do not need small rubber bands. If you want braces to be hard to see, you can choose clear braces or lingual braces. Lingual braces are special because they are attached to the back of the teeth. Some people even use clear removable aligners to move their teeth.
Treatment can take anywhere from six months to two and a half years. Every few weeks, you will visit the doctor for an adjustment.
The doctor will change the wires or the colorful elastic bands. Once the braces are finally removed, the work is not quite done. You will likely need to wear a retainer to keep your teeth straight. A retainer is often a clear plate that fits over your teeth. Most people wear them for about six months after their braces come off. This stops the teeth from moving back to their old spots.
Dental braces are orthodontic devices used to align and straighten teeth. They help position teeth correctly in relation to a person's bite. This process can improve overall dental health by correcting various issues. Common problems include overbites, underbites, and cross bites. Braces can also fix open bites, deep bites, gaps, or crooked teeth.
While some use braces for medical reasons, others use them for cosmetic purposes. In many first-world economies, cosmetic use is quite common.
The movement of teeth relies on constant force and pressure. This process involves four main elements: brackets, bonding material, an archwire, and ligature elastics, also called O-rings. The archwire puts pressure on the brackets, which in turn pushes the teeth. Sometimes, dentists use springs or rubber bands to apply force in specific directions. This constant pressure moves teeth into new positions over time.
To move a tooth, the body must undergo bone remodelling. This is a biomechanical process where bone becomes stronger or weaker based on load. Cells called osteoclasts and osteoblasts manage this change. As the tooth moves, the periodontal ligament is stretched or compressed. The body then uses bone deposition to create new bone that supports the tooth in its new location.
There are several different types of braces available today. Traditional metal braces, often called "train track braces," are made of stainless steel.
Some patients use gold-plated stainless steel if they have a nickel allergy. Titanium braces are another option because they are light and strong. Self-ligating braces are a second common type that uses a built-in system to secure the archwire. These do not require elastic ties and may reduce treatment time and pain. For those seeking a more subtle look, clear braces or lingual braces are available. Lingual braces are custom-made and bonded to the back of the teeth, making them invisible from the front.
Some people also use progressive, clear removable aligners for simpler cases.
Applying braces is a precise medical procedure. In North America, most treatment is performed by orthodontists. These are dentists who completed two to three years of additional post-doctoral training.
The process begins with a consultation and a visual inspection of the teeth. Doctors then take X-rays, moulds, and impressions to analyze the problem. Many modern clinics now use digital models created by laser-scanning dental impressions. This allows for computer-automated treatment simulations in a virtual setting. To prepare for the braces, a doctor might use orthodontic spacers to create room between the teeth. Brackets are then attached to the teeth using dental cement and cured with a light.
Treatment duration and complexity vary for every patient. Most treatments last between six months and two and a half years. In extreme cases, a patient might require orthognathic surgery. If there is not enough space in the mouth, a doctor may perform an extraction to remove a tooth. Another method is expansion, which uses a palatal expander to make the dental arch larger.
For children and teenagers, a headgear appliance might be used to keep teeth from moving. Patients typically visit the orthodontist every three to six weeks for adjustments. During these visits, the doctor replaces or modifies the archwire and the colorful ligatures. This frequent adjustment helps shift the teeth into the correct final position.
Once the braces are removed, the work is not yet finished. The teeth have a tendency to move back to their original positions. To prevent this, patients use retainers to keep the teeth in alignment.
Hawley retainers are a very common type of retainer. Many patients use a transparent plate for about six months after treatment. For patients who had long or difficult treatments, a fixative wire might be attached to the back of the teeth. This provides extra support to ensure the teeth stay straight. Some patients may also need a gum lift or a fiberotomy to improve the gumline before using a retainer.
Modern orthodontics continues to evolve with new technologies. Customized orthodontic systems now combine 3-D imaging with treatment planning software. Some systems even use a robot to custom-bend the archwire for the patient. Additionally, modern archwires often use nickel-titanium or temperature-sensitive materials. These wires are limp and flexible when cold, making them easy to thread through brackets. Once they reach body temperature, they stiffen and apply a constant, light force to the teeth. This combination of biology and technology allows for more efficient and comfortable results.
