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 periodontist 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.

Understanding your wisdom teeth

Many patients ask whether wisdom teeth are really necessary since so many people have them removed.

The fact is that wisdom teeth are a valuable asset to the mouth when they are healthy and properly positioned.

However, problems can occur that sometimes make it better to have them removed.

For example, when the jaw isn’t large enough, the wisdom teeth can become impacted – misaligned or unable to grow in properly. They may grow sideways, emerge only part way from the gum or remain trapped beneath the gum and bone.

The reasons wisdom teeth may have to be extracted include:
– The teeth have only partially erupted. This leaves an opening for bacteria which cause infection.
– There is a chance the wisdom teeth will damage adjacent teeth.
– A cyst forms which may destroy surrounding structures such as bone or tooth roots.

Ask your dentist about the health and positioning of your wisdom teeth.

Your dentist will tell you if there are any issues and will recommend any steps needed.

What is plaque and how does it affect your teeth?

Plaque is a sticky film of bacteria that covers our teeth and, when we eat something, these bacteria release acids that attack the tooth enamel.

When these attacks are repeated over time, the enamel will break down and this will eventually lead to cavities.

When plaque is not removed through daily brushing and cleaning it hardens into calculus or tartar. When tartar collects above the gum line, brushing and cleaning between the teeth becomes more difficult.

The gum tissue can become swollen or may bleed. This is called gingivitis and it is the early stage of periodontal (gum) disease.

There are several steps you can take to protect yourself against this happening:

– Brush your teeth twice a day with fluoride toothpaste
– Clean between teeth daily with floss or an interdental cleaner
– Eat a balanced diet and limit the number of snacks between meals
– Visit your dentist regularly for professional cleanings and oral exams
– Ask your dentist about sealants – these are protective coatings that can be applied to the back teeth where decay often starts.

If you take steps to remove the plaque each day, you have a greater chance of avoiding tooth and gum problems.

How a baby’s first teeth develop

A newly born baby usually has no teeth visible but most have begun to develop primary or baby teeth.

These generally begin to appear about six months after birth.

Over their first few years, they will develop all 20 primary teeth and will usually have them all in place by age three.

The teething process is uncomfortable for many babies and they can become sleepless and irritable. They also might lose their appetite or drool more than usual.

If your infant has a fever or diarrhea while teething or continues to be cranky and uncomfortable, call your physician.

Sometimes when a tooth erupts, an eruption cyst may develop. The tooth will eventually rupture this as it pushes through the gums and these cysts are usually harmless and should be left alone.

If a baby has sore or tender gums when they are teething, it can help to gently rub the gum with a clean finger, a small, cool spoon or a wet gauze pad.

When this happens, your dentist or pediatrician may suggest a pacifier, teething ring or a special “numbing” salve for the gums.

When the teeth begin to erupt, you should brush them with a soft-bristled toothbrush and a little water to prevent tooth decay.

Toothpaste is not recommended until a child reaches age two. When a child begins using toothpaste, you need to supervise the brushing to make sure they don’t swallow it.

Regular dental checks should begin after your child’s first tooth appears or by their first birthday.

The secrets of brushing and flossing your teeth effectively

Though many of us say we brush our teeth regularly, you get the best results by making sure you brush properly.

Here are the steps you should follow:

First, place the toothbrush at a 45-degree angle to your gums.

Then, move the brush back and forth gently in short (tooth-wide) strokes.

Brush the outer tooth surfaces, the inner tooth surfaces, and the chewing surfaces of the teeth.

Use the “toe” of the brush to clean the inside surfaces of the front teeth, using a gentle up-and-down stroke.

Finally, brush your tongue to remove bacteria and freshen your breath.

As well as brushing your teeth, you should floss them every day. Here’s how to floss for best results.

Break off about 18 inches of floss and wind most of it around one of your middle fingers.

Then wind the remaining floss around the same finger on the opposite hand. This finger will take up the floss as it becomes dirty.

Hold the floss tightly between your thumbs and forefingers.

Guide the floss between your teeth using a gentle rubbing motion. Never snap the floss into the gums.

When the floss reaches the gum line, curve it into a C shape against one tooth. Gently slide it into the space between the gum and the tooth.

Hold the floss tightly against the tooth. Gently rub the side of the tooth, moving the floss away from the gum with up and down motions.

Repeat this method on the rest of your teeth.

Don’t forget the back side of your last tooth.

If you have difficulty handling dental floss, consider other types of interdental cleaner such as special brushes, picks or sticks.

Your dentist or hygienist will be able to give your further tips on how to brush and floss for best results.

How sealants can give your teeth extra protection

Sealants are made from plastic material applied to the back teeth to protect the enamel from plaque and acids.

The plastic bonds into the depressions and grooves (pits and fissures) of the chewing surfaces of the back teeth – premolars and molars.

Although thorough brushing and flossing can help remove food particles and plaque from smooth surfaces of teeth, the toothbrush bristles cannot reach all the way into the depressions and grooves to extract food and plaque.

The benefit of sealants is that they protect these vulnerable areas by “sealing out” plaque and food.

Your dentist can apply sealants quite easily and it takes only a few minutes to seal each tooth.

The teeth being sealed will first be cleaned. Then the chewing surfaces are roughened with an acid solution which makes it easier for the sealant to stick to the tooth.

The sealant is then ‘painted’ onto the tooth enamel, where it bonds directly to the tooth and hardens.

Sometimes a special curing light is used to help the sealant harden.

As long as the sealant remains intact, the tooth surface will be protected from decay.
They usually last several years before a reapplication is needed. Your dentist will check the condition of the sealants during your regular visits and reapply them when necessary.

Sealants are ideal for children because the risk of developing pit and fissure decay starts early in life. However, many adults can benefit from sealants as well.

Your dentist can tell you whether sealants would help your oral hygiene program.

How dentistry has developed over the last 300 years
