Sometimes teeth are not straight.
They may be too crowded. A doctor can help fix them. They use small tools to move teeth. This helps your smile look good. Do you have straight teeth?
Sometimes teeth and jaws do not line up.
This can happen if a child eats mostly soft foods. Small jaws might not have enough room for teeth.
A special doctor can help fix this. They use tools like braces to move teeth. This can take a few months or years.
Some tools can be taken out. Other tools stay on the teeth. These tools help your smile look great.
Sometimes teeth and jaws do not line up correctly. This is called malocclusion. It means the bite is not normal. This happens to many people. About 56% of people in the world have it. One reason is diet. If children eat mostly soft foods, their jaws might stay small. Small jaws do not have enough room for teeth to grow in.
A special dentist can help. They use tools to move teeth and jaws. This can take a few months or even years. Some tools are removable. Others are fixed, which means they stay on the teeth.
In the past, doctors used different tools. Edward Angle is called the "father of modern orthodontics." He made many systems to fix teeth. One was the ribbon arch. It used a wire that could spring to move teeth. Later, doctors used x-rays. These showed that some problems come from the jaw, not just the teeth.
Today, doctors use metal brackets. They glue these to the teeth. A new system called the straight-wire appliance is very helpful. It uses special brackets to help teeth find the right spot.
Orthodontics is a special part of dentistry. It helps doctors fix teeth and jaws that are not in the right place. This can include fixing a bite that does not line up correctly. Many people have teeth that are crowded or sticking out. In fact, about 56% of people around the world have this issue. One reason this happens is because of what children eat. If children eat mostly soft foods instead of fresh fruits and vegetables, their jaws might grow smaller. Smaller jaws do not have enough room for all the teeth to come in properly.
There are many ways to fix these dental problems. Doctors can use different tools to move teeth slowly over time. Some tools are removable, so a person can take them out. Other tools are fixed, which means they stay glued to the teeth. Treatment can take anywhere from a few months to several years. For very serious cases, a person might even need jaw surgery. Most people start treatment before they become adults. This is because bones are easier to adjust when they are still growing.
People have tried to fix teeth for a very long time. Evidence from Greek and Etruscan items shows tools used as far back as 1000 BC. However, modern orthodontics really began in the mid-1800s. Norman William Kingsley was a very important person in this early time. He wrote a book called Oral Deformities to document how to help patients. He was also a pioneer in treating cleft palates. Later, Edward Angle became a major leader in the field. He is known as the "father of modern orthodontics."
Dr. Edward Angle created many important systems for treating teeth. He made the E-arch, the pin and tube, the ribbon arch, and the edgewise system. The E-arch used a rigid frame to help teeth follow a specific shape. The pin and tube system used small tubes to move teeth. Later, the ribbon arch became popular because its wire could spring to align teeth. In 1915, the American Journal of Orthodontics was created to help the science grow. By the mid-20th century, doctors realized that jaws, not just teeth, needed fixing. This led to new tools to help jaw growth.
Technology has changed how orthodontists work every day. Until the mid-1970s, braces were made by wrapping metal around each tooth. Now, doctors use special glue to bond metal brackets directly to the teeth. In 1972, Lawrence F. Andrews defined what a perfect bite should look like. He later introduced the straight-wire appliance system in 1976. This system changed everything because the brackets do most of the work. It uses a special combination of brackets and wires to position teeth. This means doctors do not have to bend the wires as much as they used to.
Orthodontics is a specialized branch of dentistry. It focuses on the diagnosis, prevention, and management of malocclusion. Malocclusion is the medical term for teeth or jaws that are not positioned correctly. It also includes fixing misaligned bite patterns. This field may also involve dentofacial orthopedics. This process modifies how a person's face grows. Misaligned teeth and jaws are very common worldwide. Research suggests the prevalence of malocclusion can be as high as 56%.
One major cause of malocclusion relates to childhood diet. Diets containing less fresh fruit and vegetables are often softer. These soft foods may cause jaws to grow smaller during development. Smaller jaws provide less room for teeth to erupt properly. To fix these issues, orthodontists use various appliances. These tools gradually adjust the position of teeth and the alignment of the jaw. Treatment can last from several months to a few years. In severe cases, a patient may require jaw surgery. Most treatment begins before adulthood. This is because pre-adult bones are easier to adjust.
Orthodontic history stretches back thousands of years. Evidence from Greek and Etruscan materials shows primitive appliances existed around 1000 BC. However, modern orthodontics began in the mid-1800s. Norman William Kingsley was a major influential figure. He published Oral Deformities to systematically document the field. Kingsley also pioneered treatments for cleft palates. He often used extraoral force to correct protruding teeth. During his era, the goal was often facial harmony and straightening teeth. Many teeth were removed to solve overcrowding. At that time, doctors did not fully appreciate the importance of an intact dentition.
Dr. Edward Angle is known as the "father of modern orthodontics." His work in 1890 changed the focus of the field. He moved the priority toward dental occlusion. Occlusion refers to how the upper and lower teeth meet. Angle created a classification system for malocclusions that is still used today. He believed that maintaining a full set of teeth was vital. He strongly opposed the practice of extracting teeth. Angle believed that perfect occlusion would naturally lead to better facial aesthetics. However, later practitioners found that focusing only on occlusion sometimes neglected facial proportions.
In the 1940s and 1950s, the field evolved again. Charles Tweed and Raymond Begg reintroduced tooth extraction. They did this to improve facial aesthetics and stability. During the postwar period, doctors began using cephalometric radiography. These are special X-rays used to measure changes in tooth and jaw positions. The X-rays revealed that many malocclusions were caused by improper jaw relations. This discovery shifted the focus toward functional jaw orthopedics. Today, clinicians use functional appliances and extraoral devices globally. These tools aim to amend growth patterns and jaw forms.
Dr. Edward Angle also developed four specific appliance systems. The first was the E-arch system. This used a rigid framework to recreate a specific arch shape. The second was the pin and tube appliance. This used vertical tubes to move teeth, but it was difficult to control. The third was the ribbon arch system. This was simpler and used wires with good spring qualities. The fourth was the edgewise appliance. Modern fixed appliances are mostly variations of the edgewise approach. Most fixed appliances use round wires first, then transition to rectangular archwires. These rectangular wires allow for much more precision during the final stages of treatment.
Recent technological advancements have revolutionized the process. Until the mid-1970s, braces were often wrapped around teeth with metal. New adhesives allowed doctors to bond metal brackets directly to the teeth. In 1972, Lawrence F. Andrews defined the characteristics of ideal occlusion. His definition included factors like correct crown angulation and tight contact points. In 1976, he introduced the straight-wire appliance system. This is also called the pre-adjusted edgewise system. This system uses a specific combination of brackets and archwires. It requires very little manual wire bending by the orthodontist. This makes the treatment much more efficient and predictable.
