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.

Common questions about dental insurance

Understanding what’s covered by your dental insurance is an important part of making sure you get the best oral care possible.

Here are some common questions that arise when people want to understand their cover better.

– If treatment my dentist recommends is not covered by my insurance, does that mean it’s not necessary?

Some plans make exclusions such as sealants, pre-existing conditions, adult orthodontics, and specialist referrals. This depends on your dental plan and you should not let the level of cover determine whether you need treatment.

– My dental benefit will only pay for a large filling but my dentist recommends I get a crown. Which should I choose?

Some plans will only cover the least expensive solution but it may not be the best option for your needs. You should decide based on your health needs and not on your insurance cover.

– My dental plan says it will pay 100 percent for checkups and cleanings but the insurance company says I owe for part of the dentist’s charge. How can this be?

Some plans provide cover based on a “customary fee” for each procedure. So, if your dentist’s fee is higher, your benefit will be based on a percentage of the customary fee instead of your dentist’s fee. Although these limits are called “customary,” they may not accurately reflect the fees that dentists charge in your area.

– Will my plan cover the care my family will need?
If your employer offers more than one plan, check the exclusions and limitations of the coverage as well as looking at the general benefits. It’s a good idea to discuss your family’s likely needs with your dentist before choosing a plan.

The plan document should specify who is eligible for coverage under the plan.

Plans offered by the same provider or employer can vary according to the contracts involved so your dentist will not be able to answer specific questions about your benefit or predict what the coverage for a particular procedure will be.

If you have specific questions about coverage, talk to your plan provider.

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, it’s 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.

Caring for people who have special needs

People at any age can have a condition that makes it difficult for them to look after their own dental health.

This could affect people who suffer from a wide range of conditons such as stroke, spinal cord injury, multiple sclerosis, mental retardation, Down syndrome, genetic disorders, Alzheimer’s disease or arthritis.

However, people in all of these categories have the same dental needs as everyone else – they need daily brushing and flossing, regular dental visits and a balanced diet.

There are some steps caregivers can take to make it easier to look after people in those categories.

If the person is uncooperative or uncontrollable, try to explain what you are about to do and schedule the task for a time of day when they are rested.

Move in a calm, slow, reassuring manner to avoid startling them. Give praise and encourage them when they help themselves.

Support the person’s head, and take special care to prevent choking or gagging when the head is tilted back.

If the person is unable or unwilling to keep their mouth open, your dentist will explain how you can make and use a mouth prop.

Ask your dentist for advice on how to care for people with special needs and check if they have facilities for caring for these needs in the dental office.

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

It’s 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, it’s important to visit your dentist regularly for professional cleanings and oral examination.

How mouth protectors can save your teeth

If you take part in sports that carry a significant risk of injury, you should wear a mouth protector.

Accidents can happen during any physical activity and, if you participate in sports such as football, hockey, basketball, baseball, gymnastics and volleyball, you might be grateful for the extra protection one day.

Something as simple as a misdirected elbow in a game, or a spill off a bicycle, can leave you with chipped or broken teeth, nerve damage to a tooth or even tooth loss.

Mouth protectors usually cover the upper teeth and they can cushion the effect of a blow to the face, reducing the risk of broken teeth and injuries to the soft tissues of the mouth.

In addition, if you wear dental appliances such as braces on your lower jaw, your dentist may suggest a mouth protector for these teeth as well.

A properly fitted mouth protector will stay in place while you are wearing it, making it easy for you to talk and breathe. The three main types of mouth protectors are:

Stock: These are inexpensive and come ready to wear. But they often don’t fit very well and they can be bulky � making breathing and talking difficult.

Boil and bite: These can also be bought at many sport stores and may fit better than stock mouth protectors. You first soften them in water, then insert them and allow them to adapt to the shape of your mouth.

Custom-fitted: Protectors that are specially made for you by your dentist are more expensive but are likely to fit better than one you buy off the shelf.

Choosing to wear the right mouth protector can help you avoid serious long-term damage to your teeth and mouth.

Dry mouth is a common problem that can harm your teeth

If your saliva flow is reduced, this can cause dry mouth which often leads to increased tooth and gum problems.

Dry mouth – known as xerostomia – is a common problem especially among older adults. It’s caused by certain medical disorders and is often a side effect of medications such as antihistamines, decongestants, pain killers and diuretics.

The common problems associated with dry mouth include:

– Constant sore throat
– Burning sensation
– Problems speaking
– Difficulty swallowing
– Hoarseness or dry nasal passages

When there is not enough saliva to lubricate your mouth, wash away food and neutralize the acids produced by plaque, there is a risk of extensive tooth decay.

If you are at risk from this condition, your dentist can recommend various methods to restore moisture.

For example, sugar-free candy or gum stimulates saliva flow, and moisture can be replaced by using artificial saliva and oral rinses.

As dry mouth is a potential side effect of many prescribed and over-the-counter medications it is a very common problem.

These medications can include antihistamines, decongestants, painkillers, high blood pressure medications, muscle relaxants, drugs for urinary incontinence, Parkinson’s disease medications, antidepressants and many others.

Fortunately there are many simple solutions available to reduce the risk to your oral health caused by dry mouth so talk to your dentist if you are on any kind of medication or you feel you may be at risk from this issue.

How older adults can handle dry mouth and taste problems

Reduced saliva flow that results in a dry mouth is a common problem among older adults.

It is caused by certain medical disorders and is often a side effect of medications such as antihistamines, decongestants, pain killers and diuretics.

Some of the common problems associated with dry mouth include:
– Constant sore throat
– Burning sensation
– Problems speaking
– Difficulty swallowing
– Hoarseness or dry nasal passages

Left untreated, dry mouth can damage your teeth. Without adequate saliva to lubricate your mouth, wash away food, and neutralize the acids produced by plaque, extensive cavities can form.

Your dentist can recommend various methods to restore moisture. For example, sugar-free candy or gum stimulates saliva flow, and moisture can be replaced by using artificial saliva and oral rinses.

Another issue that can affect older adults is a loss of appetite due to a change in your sense of taste. Besides an age-related decrease in the sense of taste and smell, certain diseases, medications and dentures can contribute to a decrease in your sense of taste.

Whether you are suffering from dry mouth or problems with your sense of taste, your dentist will be able to make suggestions to help.

How cosmetic dentistry can change your smile – and your life

Modern cosmetic dentistry has created many opportunities that did not exist before for people to improve their appearance and change the way they feel about themselves.

Although cosmetic dentistry really did not exist a few yaears ago, it now attracts interest from a wide range of people.

There are few people who don’t want to improve their appearance by making their teeth straighter and whiter so that they look better when they smile.

New technology and procedures have created many more opportunities for dentists to help patients look better.

One of the most important opportunities for doing this is porcelain veneers.

These are custom-made wafers that the dentist places over the front of the teeth to repair damage and make them look better.

They can overcome many cosmetic dental problems such as whitening stained or discolored teeth, closing gaps between teeth or correcting a crooked smile without the need for braces.

They can also cover up chips and imperfections so that the smile looks much better.

Another important cosmetic trend is the increased use of white fillings.

White fillings now are more lifelike than ever and they last longer than previously.

They have become the material of choice for many dentists as they blend in with teeth and look better.

If you feel your smile is less than perfect, talk to your dentist about how it could be better.

How dental x-rays help improve your oral health

Many diseases of the teeth and surrounding tissues cannot be seen when your dentist examines your mouth so an X-ray examination can reveal important additional information:

For example, X-rays can help show:
– Small areas of decay between the teeth or below existing fillings
– Infections in the bone
– Gum disease
– Abscesses or cysts
– Developmental abnormalities
– Some types of tumors

The way they work is that more X-rays are absorbed by the denser parts (such as teeth and bone) than by soft tissues (such as cheeks and gums). This creates an image called a radiograph.

Tooth decay, infections and signs of gum disease appear darker because of more X-ray penetration. The interpretation of these radiographs allows the dentist to safely and accurately detect hidden abnormalities.

The frequency of X-rays (radiographs) will depend on your specific health needs.

Your dentist will review your history, examine your mouth and decide whether you need radiographs and what type.

When you are a new patient, the dentist may recommend radiographs to establish how the hidden areas of your mouth currently look to help identify changes that occur later.

X-rays can help identify and treat dental problems at an early stage and so can save time, money and unnecessary discomfort.
