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.

Taking care of your teeth and gums during pregnancy

Your oral health is an important part of your overall health, and this is never more true than during pregnancy.

Good oral health habits not only help prevent oral problems during pregnancy, they also help the health of your unborn child.

What you eat during your pregnancy affects the development of your unborn child — including teeth.

Eating a balanced diet is necessary to provide the correct amounts of nutrients to nourish both you and your child.

Your babys teeth begin to develop between the third and sixth month of pregnancy, so it is important that you receive sufficient nutrients especially calcium, protein, phosphorous, and vitamins A, C, and D.

There is a common myth that calcium is lost from the mothers teeth during pregnancy.

In fact, the calcium your baby needs is provided by your diet, not by your teeth. If your diet does not provide enough calcium, your body will provide this mineral from stores in your bones.

If you have an adequate intake of dairy products the main source of calcium or take any supplements your obstetrician recommends this will help you get the calcium you need.

To help prevent tooth decay and periodontal disease, brush your teeth thoroughly twice a day with fluoride toothpaste to remove plaque. Be sure to clean between your teeth daily with floss or interdental cleaners.

Make regular visits to your dentist during your pregnancy to ensure the best possible health for you and your baby.

What will it be like living with dentures?

People who are new to wearing dentures naturally have many questions about how their life will change.

New dentures may feel awkward for a few weeks until you become accustomed to them. The dentures may feel loose while the muscles of your cheek and tongue learn to keep them in place.

During this time, its not unusual to experience minor irritation or soreness. You may find that saliva flow temporarily increases.

As your mouth becomes accustomed to the dentures, these problems should diminish.

Dentures can be made to closely resemble your natural teeth so that little change in appearance will be noticeable. Dentures may even improve the look of your smile and help fill out the appearance of your face and profile.

Eating will take a little practice. Start with soft foods cut into small pieces. Chew slowly using both sides of your mouth at the same time to prevent the dentures from tipping. As you become accustomed to chewing, add other foods until you return to your normal diet.

Continue to chew food using both sides of the mouth at the same time. Be cautious with hot or hard foods and sharp-edged bones or shells.

Initially you may also find that wearing dentures changes how you speak. Pronouncing certain words may require practice. Reading out loud and repeating troublesome words will help. If your dentures “click” while you’re talking, speak more slowly.

You may find that your dentures occasionally slip when you laugh, cough or smile.

After your dentures are fitted, youll have a few follow-up appointments with your dentist to take care of any initial issues and to answer any questions you have.

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.

Tips for people with difficulty handling a toothbrush

There are many people who find it difficult to look after their dental health properly because they have problems handling a toothbrush.

This can be due to a severe physical disability or simply basic dexterity problems.

There are a few simple steps you can take to make it easier for people who find it difficult to hold on to a toothbrush or dental floss.

Here are some simple ‘home remedies’:

– Use a wide elastic band to attach the brush to the hand

– Enlarge the brush handle with a sponge, rubber ball or bicycle handle grip

– Wind an elastic bandage or adhesive tape around the handle

– Lengthen the handle with a piece of wood or plastic such as a ruler, popsicle stick or tongue depressor

– Tie floss into a loop for easier handling

– Use an electric toothbrush or commercial floss holder

Your dentist will be able to provide specific guidance and further tips for people who need an easier way to handle a toothbrush and floss.

Is it safe to have an X-ray while pregnant?

Some women worry about whether its safe to have an X-ray exam while they are pregnant.

This can cause them to put off treatment they need.

However, untreated dental infections can pose a risk to the fetus, and dental treatment may be necessary to maintain the health of the mother and child. Sometimes this will mean an X-ray is necessary.

Radiation from dental X-rays is extremely low but every precaution is taken to minimize radiation exposure.

For example, a leaded apron reduces exposure to the abdomen and should be used when a dental radiograph is taken.

In addition, a leaded thyroid collar can protect the thyroid from radiation, and should be used whenever possible. The use of a leaded thyroid collar is strongly recommended for women of childbearing age, pregnant women and children.

Overall there is no reason to avoid dental radiographs (X-rays) while pregnant, breastfeeding or trying to become pregnant.

Follow your dentists advice and ask questions if you have any concerns.

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.

What dentists are doing to improve services for older adults

As people are living longer and enjoying good health for many years, dentists are increasingly offering improved services to recognize the special needs of older adults.

This growing segment of the population is wearing fewer dentures and they are keeping their natural teeth longer. They are also concerned to maintain good health and a great smile for many years.

However, patients in this group sometimes require special consideration because reduced mobility and dexterity may make daily oral hygiene difficult.

And certain medical conditions and impairment may make them more anxious when visiting the dentist.

For example, problems with vision or hearing loss may cause worry. Always let the dentist and staff know if you have any concerns so that they can adjust their treatment and their pace to meet your needs.

Older patients can sometimes put up with problems such as toothaches, bleeding gums and clicking dentures because they are not aware of the wide range of treatments and techniques now available.

Dentists are increasingly sensitive to the special needs of and the importance of dental health in the older patient.

As many older patients are more health conscious than ever before, regular visits to the dentist ensure their oral health is an important part of their overall health.

How Invisalign can replace metal braces

The Invisalign system is a series of clear, thin, mouthguards that fit over the teeth and can gradually straighten them.

These have been called invisible braces as they can be an effective alternative to metal braces in some circumstances.

The big advantage of Invisalign is much improved appearance and comfort.

Invisalign mouthguards can be removed during eating and when brushing and flossing. As traditional braces may trap food and plaque, this is another major benefit of Invisalign.

While the system has advantages, it also has some drawbacks.

For example, it is more expensive – costing 25-50 percent more than metal braces.

Also the fact that you remove the mouthguards more often means that you may forget to wear them and it could take longer for you to achieve the desired results.

Invisalign is better suited to some people than others – for example, it may be particularly suitable for adults who have slight to moderate spacing or crowding of their teeth.

Your dentist will be able to tell you if you might be a suitable candiate for Invisalign.

You will get more detailed advice from an orthodontist who has been certified in the Invisalign system.

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.
