Different types of dentist and how they help your oral care

While many people see dentists as the single group of people who look after the health of your teeth and mouth, there are various specialist categories that help you in different ways.

The categorization of a dentist will depend on their education, training and experience.

Here are some of the main specialist areas of dentistry:

Endodontics: Concerned with the dental pulp – the part in the center of a tooth made up of living soft tissue and cells and root canal therapy

Oral and Maxillofacial Pathology: This deals with the identification, and management of diseases affecting the oral and maxillofacial regions

Oral and Maxillofacial Radiology: Deals with the production and interpretation of images and data produced by radiant energy that are used for the diagnosis and management of diseases, disorders and conditions of the oral and maxillofacial region

Oral and Maxillofacial Surgery: Diagnosis and surgical treatment of diseases, injuries and defects of the tissues including extractions, facial surgery and implants

Orthodontics and Dentofacial Orthopaedics: Mainly deals with diagnosis, prevention and treatment of misaligned teeth and modification of midface and mandibular growth

Pediatric Dentistry: Provides preventive and therapeutic oral health care for infants and children through adolescence.

Periodontics: Prevention, diagnosis and treatment of diseases of the supporting and surrounding tissues of the teeth and the maintenance of the health, function and esthetics of these structures and tissues. Most periodonitist place implants

Prosthodontics: Diagnosis, treatment planning, rehabilitation and maintenance associated with missing or deficient teeth and/or oral and maxillofacial tissues. Includes dentures, bridges and the restoration of implants.

Plus, of course, general dentists provide everyday care and many specialist services to maintain your oral health.

Oral cancer: Why early detection is so important

Although thousands of Americans die every year from oral cancer, there is a high chance it can be cured if it is caught early enough.

Each year, more than 30,000 Americans are diagnosed with oral cancer and only half of those diagnosed survive more than five years.

But nowadays, dentists have the skills and tools to ensure that early signs of cancer and pre-cancerous conditions are identified.

If it is caught early, there is a much higher chance that, with your dentists help, you could win a battle against oral cancer.

The key is to know the early signs and see your dentist regularly.

Oral cancer often starts as a tiny, unnoticed white or red spot or sore anywhere in the mouth.

It can affect any area of the oral cavity including the lips, gum tissue, cheek lining, tongue or the palate.

Other signs include:
- A sore that bleeds easily or does not heal
- A change in the color of the oral tissues
- A lump, thickening, rough spot, crust or small eroded area
- Pain, tenderness, or numbness anywhere in the mouth or on the lips
- Difficulty chewing, swallowing, speaking or moving the jaw or tongue
- A change in the way the teeth fit together

Oral Cancer most often occurs in those who use any form of tobacco. Smoking combined with alcohol use greatly increases the risk.

However, oral cancer which is most likely to strike after age 40 can occur in people who do not smoke and have no other known risk factors.

Diets with a lot of fruits and vegetables may help prevent its development.

Oral cancer screening is a routine part of a dental examination so regular checkups with an examination of the entire mouth are essential in the early detection of cancerous and pre-cancerous conditions.

The early years of dentistry and teeth

Although there have been huge advances in dental care in recent years, there are records of people dealing with teeth going back over thousands of years.

Here are some of the key dates from the early years in the development of dentistry.

5000 BC: A Sumerian text describes tooth worms as the cause of dental decay.

2600 BC: Hesy-Re, an Egyptian scribe, often called the first dentist, dies. An inscription on his tomb includes the title the greatest of those who deal with teeth, and of physicians.

500-300 BC: Hippocrates and Aristotle write about dentistry, including the eruption pattern of teeth, treating decayed teeth and gum disease, extracting teeth with forceps, and using wires to stabilize loose teeth and fractured jaws.

166-201 AD: The Etruscans practice dental prosthetics using gold crowns and fixed bridgework.

500-1000: During the Early Middle Ages in Europe, medicine, surgery, and dentistry, are generally practiced by monks, the most educated people of the period

700: A medical text in China mentions the use of silver paste, a type of amalgam.

1130-1163: A series of Papal edicts prohibit monks from performing any type of surgery, bloodletting or tooth extraction. Barbers often assisted monks in their surgical ministry because they visited monasteries to shave the heads of monks and the tools of the barber trade sharp knives and razors were useful for surgery. Following the edicts, barbers assume the monks surgical duties: bloodletting, lancing abscesses, extracting teeth, etc.

1210: A Guild of Barbers is established in France. Barbers eventually evolve into two groups: surgeons who were educated and trained to perform complex surgical operations; and lay barbers, or barber-surgeons, who performed more routine hygienic services including shaving, bleeding and tooth extraction.

1400s: A series of royal decrees in France prohibit lay barbers from practicing all surgical procedures except bleeding, cupping, leeching, and extracting teeth.

Why cavities arent just for kids

Tooth decay or cavities result from destruction of the tooth enamel and can lead to a range of problems from toothache to bad breath.

Cavities occur when foods containing carbohydrates (sugars and starches) such as milk, sugared drinks, cakes or candy are frequently left on the teeth.

Bacteria that live in the mouth thrive on these foods, producing acids as a result. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay.

Many people associate cavities with children but the changes that occur with aging make cavities an adult problem, too.

Recession of the gums away from the teeth, combined with an increased incidence of gum disease, can expose tooth roots to plaque.

Tooth roots are covered with cementum, a softer tissue than enamel. They are susceptible to decay and are more sensitive to touch and to hot and cold. The majority of people over age 50 have tooth-root decay.

Decay around the edges of fillings is also common to older adults. As many of them did not benefit from fluoride and modern preventive dental care when they were younger, they often have a number of dental fillings.

Over the years, these fillings may weaken, fracture and leak around the edges.

Bacteria accumulate in these tiny crevices causing acid to build up which leads to decay.

You can help prevent tooth decay by following these tips:

- Brush twice a day with fluoride toothpaste
- Clean between your teeth daily with floss or interdental cleaner
- Eat nutritious and balanced meals and limit snacking

Its also worth asking your dentist about supplemental fluoride, which strengthens your teeth, and about dental sealants, a plastic protective coating which is applied to the chewing surfaces of the back teeth to protect them from decay.

In addition, its important to visit your dentist regularly for professional cleanings and oral examination.
