Dentistry is a specialized branch of medicine. It focuses on the teeth, gums, and the entire mouth.

This field involves the study, diagnosis, and prevention of oral diseases. Practitioners often focus on dentition, which is the arrangement and development of teeth. They also examine the oral mucosa, the soft lining of the mouth. Dentistry may even include the craniofacial complex, such as the temporomandibular joint.

This work is essential for maintaining overall human health.

Dental treatments follow specific clinical processes to restore health. Dentists often begin by using radiographs, or X-rays, to inspect the mouth. These images help identify tooth deformities or oral maladies. To fix a damaged tooth, a dentist might perform a restoration. This includes using fillings, crowns, or bridges. If a tooth is too damaged, they may perform an extraction to remove it.

For deeper issues, they use endodontic therapy, which is a root canal treatment. Dentists can also prescribe medications like antibiotics or sedatives to manage patients.

There are many different types of dental care and specialists. General dentists can perform most common procedures like restorative and periodontal therapy. However, many choose to specialize in specific areas. Pediatric dentistry, or pedodontics, focuses specifically on children. Periodontics is the study and treatment of the periodontium, which supports the teeth. Endodontics focuses on the dental pulp and its surrounding tissues.

Some specialists, like oral and maxillofacial surgeons, may even require both medical and dental degrees.

History shows that dentistry is an ancient practice. The earliest evidence dates from 7000 BC to 5500 BC. It is thought to be one of the first medical specializations.

In 1828, John M. Harris started the first dental school in Ohio. The Baltimore College of Dental Surgery opened in 1840. In the United Kingdom, the first dental schools opened in London in 1859. Over time, laws like the British Dentists Act 1878 helped regulate the profession. These rules ensured only qualified practitioners could use the title of dentist.

Modern dentistry relies on evidence-based practices. This means using high-quality scientific research to guide all medical decisions. For example, dentists use fluoride in water and toothpaste to prevent decay. They also study how systemic diseases affect the mouth. Conditions like diabetes, osteoporosis, and celiac disease can impact oral health.

In some cases, irreversible enamel defects can be the only clue to a celiac diagnosis. Dentists even use hematology, the study of blood, to prevent complications during surgery.

Specialized fields allow for very precise medical care. Anesthesiology in dentistry deals with advanced sedation and pain management. Cosmetic dentistry focuses on improving the appearance of a patient's smile. Forensic odontology involves using dental evidence to help identify people in legal cases.

Prosthodontics involves replacing missing teeth with dentures or bridges. Some experts even practice maxillofacial prosthetics. They help patients who have lost facial features due to trauma or tumors. This demonstrates how diverse the field of dental medicine can be.

Finally, it is important to understand oral-systemic health. This concept describes how oral health affects the entire body. Many studies show that gum disease is linked to increased risks of heart disease and diabetes. Oral infections can also be connected to preterm birth. Because the mouth is connected to the rest of the body, dental care is vital. Regular checkups and proper hygiene help protect both the mouth and the whole system.
