Overview
Dentistry is a medical specialty that focuses on oral health, including the teeth, gums, jaw-related structures, and the tissues inside the mouth. Dental professionals work to prevent disease, relieve pain, restore function, and improve appearance when needed. Good oral health supports eating, speaking, social interaction, and overall well-being.
Key Symptoms
People may need dental care for tooth pain, sensitivity to hot or cold, swollen or bleeding gums, bad breath, mouth sores, loose teeth, or trouble chewing. Broken teeth, jaw discomfort, and changes in the way the teeth fit together can also be reasons to seek care. Some oral problems cause few symptoms at first, which is why routine visits matter.
Causes and Risk Factors
Dental problems can result from plaque buildup, frequent sugar exposure, poor oral hygiene, tobacco use, alcohol use, dry mouth, injuries, and infections. Risk can also be affected by limited access to dental care, some medicines, certain health conditions, and age. Mouth and gum problems may become more likely when regular prevention is difficult.
Who Is Affected
People of all ages can need dental care, from young children to older adults. Children may develop cavities early, while adults may face gum disease, tooth wear, or tooth loss. People with chronic health conditions, braces, dentures, or reduced saliva may need closer monitoring.
Prevention
Prevention usually includes brushing twice daily with fluoride toothpaste, cleaning between teeth, limiting sugary foods and drinks, and having regular dental checkups. Avoiding tobacco and reducing alcohol use can also protect oral tissues. Community measures such as fluoridated water, where available, can help lower tooth decay risk.
Diagnosis and Tests
Dentists diagnose oral health problems by asking about symptoms, examining the mouth, and checking the teeth, gums, tongue, and other tissues. They may use dental X-rays or other imaging to look for decay, infection, bone loss, or hidden damage. In some situations, dentists refer people to specialists such as orthodontists, oral surgeons, periodontists, or oral medicine experts.
Treatment Categories
Dental treatment may include preventive care such as cleanings, fluoride treatments, and sealants, as well as procedures to repair or replace damaged teeth. Care can also involve treatment for gum disease, infections, injuries, bite problems, or oral pain. Some people need specialist care for braces, surgery, root canal treatment, dentures, implants, or evaluation of unusual mouth lesions.
Diet and Lifestyle
A diet lower in free sugars can support oral health, especially by reducing frequent sugary snacks and drinks. Drinking water, maintaining daily mouth care, and using protective gear during contact sports can help reduce injury and disease. Tobacco use increases the risk of gum disease, tooth loss, and oral cancer, so stopping tobacco is an important step for many people.
When to Seek Medical Care
Contact a dentist or healthcare professional if you have ongoing toothache, swelling, bleeding gums, mouth sores that do not heal, loose teeth, or pain when chewing. Care is also important after a chipped, cracked, or knocked-out tooth, or if dentures or braces are causing sores or difficulty eating. Early assessment can help limit complications and preserve function.
When It May Be an Emergency
Urgent or emergency care may be needed for facial swelling, trouble breathing or swallowing, heavy bleeding from the mouth, severe infection, or major dental trauma. A knocked-out adult tooth should be treated quickly. Fever with dental pain or swelling can also signal a more serious problem and needs prompt medical attention.
