The difference between canker sores and cold sores

Although canker sores are often confused with cold sores, there is a difference.

Canker sores occur inside the mouth, and cold sores usually occur outside the mouth.

Canker sores are small ulcers with a white or gray base and a red border. There can be one or more sores in the mouth. They are very common and often recur.

They usually heal in a week or two and rinsing with antimicrobial mouthrinses may help reduce the irritation.

Cold sores – also called fever blisters – are composed of groups of painful, fluid-filled blisters that often erupt around the lips and sometimes under the nose or chin.

Cold sores are usually caused by herpes virus type I and are very contagious. They usually heal in about a week.

Over-the-counter topical anesthetics can provide temporary relief and prescription antiviral drugs may reduce these kinds of viral infections.

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. Heres 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.

Common mouth sores: causes and cures

Mouth sores can be very annoying and painful and can have many causes.

The causes can range from infections – bacterial, viral or fungal – to a loose orthodontic wire or a denture that doesn’t fit or a sharp edge from a broken tooth or filling.

But mouth sores may be symptoms of an underlying disease or problem.

So, if you’ve had any mouth sore that lasts a week or longer, its a good idea to get your dentist to check it out.

Here are some of the most common mouth sores:

Canker sores: These are small ulcers with a white or gray base and a red border. They appear inside the mouth and are not contagious though they often return. Problems such as poor immune systems, viruses or fatigue and stress may be involved. They usually heal on their own after a week or two.

Cold sores: Cold sores are annoying and painful. They are also known as fever blisters or Herpes simplex and are groups of fluid-filled blisters. They often erupt around the lips and sometimes under the nose or around the chin. Cold sores caused by herpes virus type 1 are very contagious and the virus stays in the body. Cold sore blisters usually heal in a week by themselves.

Candidiasis: This fungal infection (also called moniliasis or oral thrush) occurs when the yeast Candida albicans reproduce in large numbers. It is common among denture wearers and people who have dry mouth syndrome are very susceptible to it. The focus is on preventing it or controlling the conditions that caused the outbreak.

Any mouth sores that last more than a few days should be checked with your dentist.

Why cavities aren’t 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.

Is bottled or tap water better for your teeth?

With many people concerned about the taste and purity of tap water, the sales of bottled water have increased significantly in recent years.

Tap water goes through a process of purification designed to eliminate suspended materials, remove tastes and odors and kill microorganisms.

Fluoride is added to most tap water supplies with the aim of reducing cavities.

Fluoride becomes incorporated into our teeth as they develop and makes them more resistant to decay. It can reverse the progress of early cavities and reduce the need for dental treatment.

Mass water fluoridation has played an important role in reducing tooth decay.

The problem with bottled waters is that they usually don’t contain fluoride.

So there is a risk that drinking bottled water can increase the risk of cavities for some people.

If you drink a lot of bottled water, you can make up for this by using fluoride toothpaste and mouth rinse.

Your dentist may even suggest a fluoride supplement if they notice an increase in cavities.

How sugar in your diet affects your teeth

The sugar content in the food you eat has a big effect on your teeth and gums.

When bacteria (plaque) come into contact with sugar in the mouth, acid is produced, which attacks the teeth for 20 minutes or more. This can eventually result in tooth decay.

That’s why drinking sugar-filled sodas, sweetened fruit drinks, and non-nutritious snacks can take a toll on teeth.

This is particularly true for children as their eating patterns and food choices affect how quickly they develop tooth decay.

Foods that contain sugars of any kind can contribute to tooth decay. However, almost all foods, including milk or vegetables, have some type of sugar. Many of them also contain important nutrients that are an important part in our diet.

To help control the amount of sugar you consume, read food labels and choose foods and beverages that are low in added sugars. Soft drinks,candy, cookies and pastries often contain added sugars.

Treating Sensitive Teeth

Sensitive teeth is a common problem that causes many people to feel discomfort with hot or cold foods and drinks.

It can also make it uncomfortable to brush or floss the teeth and therefore can lead to further oral problems.

However, sensitive teeth can be treated.

If you suffer from this, your dentist may suggest that you try a desensitizing toothpaste, which contains compounds that help block transmission of sensation from the tooth surface to the nerve.

For desensitizing toothpaste to work, you normally have to make several applications.

If the desensitizing toothpaste does not help, your dentist may suggest further solutions.

For example, fluoride gel – which strengthens tooth enamel and reduces the transmission of sensations – may be applied to the sensitive areas of the teeth.

If the sensitivity is caused by receding gums, your dentist may use bonding agents that “seal” the sensitive teeth.

The sealer is usually made of a plastic material.

If there is severe hypersensitivity which cannot be treated by other means, there is the option of endodontic (root canal) treatment.

Sensitive teeth is a problem that can stop you enjoying your food but is one that can often be solved.

Why its not inevitable that youll lose your teeth as you get older

Advancements in dental techniques and the increased focus on preventive dentistry means older adults are keeping their natural teeth longer than ever before.

A survey by the National Institute of Dental and Craniofacial Research showed that the rate of toothlessness in the 55 to 64 age group has dropped 60 percent since 1960.

Whatever your age, its important to practice good oral hygiene at home and to visit your dentist regularly. A few simple steps can help you maintain good oral health throughout your life.

Plaque, the sticky, colorless layer of bacteria that causes tooth decay and gum disease, can build up quickly on the teeth of older adults, particularly when they neglect oral hygiene. This can increase the risk for tooth decay and periodontal disease.

So its important to brush your teeth twice a day with fluoride toothpaste, and clean between your teeth daily with floss or interdental cleaners.

Regular dental checkups are also an important part of caring for your teeth.

This can help you save your teeth and gums and prevent other dental problems. It will save you time and money in the long-run as well.

The power of panormaic x-rays

X-rays are extremely valuable for helping dentists identify issues that may not show up on normal oral examination.

The three most common types of dental X-rays are the bitewing, periapical and panoramic X-rays.

Panoramic X-rays give a broad overview of the entire mouth – supplying information about the teeth, upper and lower jawbone, sinuses, and other hard and soft tissues of the head and neck.

Unlike other X-rays, where the film is placed inside the patients mouth, the panoramic film is contained in a machine that moves around the patient’s head. So they are very easy to use.

Panoramic X-rays are often used to check wisdom teeth but they will also reveal deep cavities and gum disease. They are also useful to help patients with past or present jaw problems or those who require full or partial removable dentures, dental implants, or braces.

They can also be valuable in assisting people who are suspected of having oral cancer or have had recent trauma to the face or teeth.

Panoramic X-rays play an important role in thorough dental examinations and are recommended at least every five years or so for most patients.

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.
