What Is the Definition of Dentistry?
Many people search online for “what is the definition of dentistry” because they want a simple explanation.
Dentistry is the branch of healthcare that focuses on the prevention, diagnosis, and treatment of diseases and conditions affecting the teeth, gums, mouth, and supporting structures.

Dentistry includes many areas such as:
- Preventive dental care

What Is the Dentistry and Why Is It Important?
To fully understand what is the dentistry, it is important to know why oral healthcare matters in daily life.
The mouth is one of the most important parts of the body. People use their teeth and mouth to eat, speak, smile, and communicate. Healthy teeth help people chew food properly, which supports digestion and nutrition.
Dentistry is important because it helps:
- Prevent tooth decay

Dentists can also detect early signs of oral cancer and other medical problems during regular dental exams.
