The facts about oral cancer

Oral cancer is not as well known as other types of cancer but it can represent a life-threatening risk if not identified early.

– It strikes an estimated 35,000 Americans each year
– More than 7,500 people (5,200 men and 2,307 women) die of these cancers each year
– More than 25% of Americans who get oral cancer will die of the disease
– On average, only half of those diagnosed with the disease will survive more than five years
– African-Americans are especially vulnerable; the incidence rate is 1/3 higher than whites and the mortality rate is almost twice as high

Although the use of tobacco and alcohol are risk factors in developing oral cancer, approximately 25% of oral cancer patients have no known risk factors.

There has been a nearly five-fold increase in incidence in oral cancer patients under age 40, many with no known risk factors.

The incidence of oral cancer in women has increased significantly, largely due to an increase in women smoking. In 1950 the male to female ratio was 6:1; by 2002, it was 2:1.

The best way to prevent oral cancer is to avoid tobacco and alcohol use.

Unusual red or white spots can form in and around the mouth. These are often harmless but they can be cancerous or pre-cancerous.

Identifying and removing these early enough is a major factor in reducing the incidence of cancer.

So knowing the risk factors and seeing your dentist for regular examinations can help prevent this deadly disease.

Dental plaque – what it is and how to avoid it

You’ve probably heard people talking about plaque and maybe you’ve some idea of what it is.

But it’s useful to know a bit more about it so that you can do what’s necessary to minimize the risks.

Plaque is a sticky film of bacteria that forms on teeth and gums.

When you’ve eaten a meal or snack, the bacteria in plaque release acids that attack tooth enamel. When this happens regularly, the enamel can weaken. This eventually leads to tooth decay.

The food we eat often causes plaque bacteria to produce acids. So, if you eat a lot of snacks, your teeth may be suffering acid attacks all day.

If you don’t remove the plaque through effective daily brushing and cleaning between the teeth, it can eventually harden into calculus or tartar.

Another effect of plaque is that it also produces substances that irritate the gums, making them red and tender or causing them to bleed easily.

If you want to prevent tooth decay and gum disease, make sure you have a balanced diet and avoid having too many snacks between meals.

When you feel like a snack, go for foods such as raw vegetables, plain yogurt, cheese or a piece of fruit.

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.

Periodontal disease: what it is and how to avoid it

Periodontal disease is an infection of the tissues that support your teeth.

There is a very slight gap (called a sulcus) between the tooth and the gum.

Periodontal diseases attack this gap and cause a breakdown in the attachment of the tooth and its supporting tissues.

When the tissues are damaged, the sulcus develops into a pocket and, as the disease gets more severe, the pocket usually gets deeper.

The two major stages of periodontal disease are gingivitis and periodontitis.

Gingivitis is a milder and reversible form of periodontal disease that only affects the gums. Gingivitis may lead to periodontitis, which is a more serious, destructive form of periodontal disease.

There are several factors that have been shown to increase the risk of developing periodontal disease:
– Systemic diseases such as diabetes
– Some types of medication
– Crooked teeth
– Bridges that no longer fit properly
– Fillings that have become defective
– Smoking
– Pregnancy

And there are a number of warning signs that can suggest a possible problem:
– Gums that bleed easily
– Red, swollen, tender gums
– Gums that have pulled away from the teeth
– Persistent bad breath or taste
– Permanent teeth that are loose or separating
– Any change in the way your teeth fit together when you bite
– Any change in the fit of partial dentures

However, it’s also possible to have periodontal disease with no warning signs.

It’s therefore important to have regular dental checkups and periodontal examinations.

If you have developed periodontal disease, the treatment will depend on how far it has progressed.

You can take steps to prevent periodontal disease from becoming more serious or recurring.

Good dental hygiene practices such as brushing twice a day, cleaning between your teeth, eating a healthy diet and having regular visits to the dentist will make a huge difference.

How removable partial dentures can help you

Removable partial dentures usually involve replacement teeth attached to plastic bases, connected by metal framework.

They attach to your natural teeth with metal clasps or �precision attachments’. Precision attachments generally look better than metal clasps and are nearly invisible.

Crowns may be required on your natural teeth to improve the fit of a removable partial denture.

When you first get a partial denture, it may feel awkward or bulky. But you will gradually get used to wearing it.

It will also take a bit of practice to get used to inserting and removing the denture. It should fit into place easily and you should never force it.

Your dentist may suggest that you wear your partial denture all the time at first. While it will be uncomfortable for a while, it will help you identify if any parts of the denture need adjustment.

After making adjustments, your dentist will probably recommend that you take the denture out of your mouth before going to bed and replace it in the morning.

With a denture, eating should become a more pleasant experience compared to having missing teeth.

But, initially, you’ll need to eat soft foods cut into small pieces. And avoid foods that are extremely sticky or hard.

Some people with missing teeth find it hard to speak clearly so wearing a partial denture may help. However, you’ll probably need to practice certain words at first to get completely comfortable.

While it can take a little geting used to initially, a partial denture can help you enjoy your food with less worries.

What to do if your tooth cracks

While our teeth are normally very strong, they can crack for a number of reasons.

Reasons could include tooth decay, trauma/injury, grinding of the teeth or a stress fracture.

Sometimes, our jaw may be stronger than our teeth and the teeth can fracture when we bite heavily on food.

We can protect our teeth in some circumstances – for example it may be advisable to wear a mouthguard during sports.

Taking proper care of the teeth and regular visits to the dentist will help keep your teeth in good shape.

If a tooth cracks, it may become painful if the nerve is exposed and the area can become tender.

If this happens, rinse your mouth with warm water to clean the area and apply a cold compress to reduce swelling. Then call your dentist immediately.

Treatment will depend on where the tooth has fractured, how close it is to the nerve and the overall condition of the tooth.

A cracked tooth may be repaired with silver alloy, gold, porcelain or plastic. Or it may require a crown or overlay or bonding, which applies porcelain or enamel to the fractured tooth.

If you contact your dentist quickly, they will be able to take the most approriate action to preserve the tooth as much as possible.

Your saliva and why it’s so important

You probably don’t give too much thought to the saliva in your mouth, but if you think of it like a bloodstream you’ll realize how important it is.

Like blood, saliva helps build and maintain the health of the soft and hard tissues.

It removes waste products from the mouth and offers first-line protection against microbial invasion that might lead to disease.

Saliva is derived from blood and therefore can also be used to detect disease.

Saliva enhances enamel protection by providing high levels of calcium and phosphate ions. It contains the minerals that maintain the integrity of the enamel surface and helps protect against caries.

When salivary flow is reduced, oral health deteriorates – much in the same way body tissues suffer if blood circulation is disrupted.

Patients with dry mouths (xerostomia) experience difficulty chewing, speaking and swallowing. A major cause of dry mouth is medication – almost eighty percent of the most commonly prescribed medications lead to dry mouth.

Chewing gum after a snack or meal stimulates salivary flow, clearing food from the mouth and neutralizing plaque acid.

Your saliva is important to your oral health both for preventing disease and in helping to diagnose problems.

How dentistry has developed over the last 300 years

When you visit a modern dental surgery, it’s hard to imagine the challenges of dental treatment without all the latest technology.

Yet specialists have been taking care of people’s teeth for thousands of years.

Here are some of the key developments over the last 300 years.

1723: French surgeon Pierre Fauchard – credited as being the father of modern dentistry – publishes the first book to describe a comprehensive system for the practice of dentistry.

1760: John Baker, the earliest medically-trained dentist to practice in America, immigrates from England and sets up practice.

1790: John Greenwood adapts his mother’s foot treadle spinning wheel to rotate a drill.

1790: Josiah Flagg, a prominent American dentist, constructs the first chair made specifically for dental patients.

1832: James Snell invents the first reclining dental chair.

1841: Alabama enacts the first dental practice act, regulating dentistry in the United States.

1844: Horace Wells, a Connecticut dentist, discovers that nitrous oxide can be used as an anesthesia and successfully uses it to conduct several extractions in his private practice.

1880s: The collapsible metal tube revolutionizes toothpaste manufacturing and marketing.

1890: Willoughby Miller notes the microbial basis of dental decay in a book which started a world-wide movement to promote regular toothbrushing and flossing.

1896: New Orleans dentist C. Edmond Kells takes the first dental x-ray of a living person in the U.S.

1938: The nylon toothbrush, the first made with synthetic bristles, appears on the market.

1945: The water fluoridation era begins when the cities of Newburgh, New York, and Grand Rapids, Michigan, add sodium fluoride to their public water systems.

1950s: The first fluoride toothpastes are marketed.

1960: The first commercial electric toothbrush, developed in Switzerland after World War II, is introduced in the United States. A cordless, rechargeable model follows in 1961.

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 your routine dental cleaning is not routine

For many patients, the dental cleaning appointment may seem little more than a more complicated version of brushing your teeth.

However, this appoinment plays a crucial role in patient education and prevention of dental disease.

The appointment is called a “dental prophylaxis,” or “prophy” and it’s one of the most important steps in your dental care program.

Here are some of the elements that it may include, depending on your needs:

– Oral hygiene evaluation

– Tooth brushing and flossing instructions

– Scaling above the gum to remove plaque and tartar

– Debridement of tartar beneath the gum

– Polishing the teeth

– Periodontal charting

It’s important to remove plaque from the teeth as it ultimately forms a hard, rough sediment known as tartar or calculus, which must be removed by a dental professional to help prevent periodontal disease.

Polishing the teeth removes stains and creates a feeling of fresh breath and a clean mouth.

The hygienist or dentist may recommend a prophylaxis visit every two to six months.

Although insurance may only cover two prophies a year, recall frequency depends on many factors and should be based on individual needs.

These appointments can help you have much better dental health and could save you a great deal of time and money in the long run.
