What Causes Sensitive Teeth?

If you sometimes find the taste of something hot or cold painful on your teeth, you may suffer from sensitive teeth.

Sensitive teeth is a common problem which may be caused by cavities and fractured teeth.

But it can also be caused by worn tooth enamel, a cracked tooth or an exposed tooth root.

Tooth enamel is the strongest substance in the body and it protects the crowns of healthy teeth. A layer called cementum protects the tooth root under the gum line.

The part underneath the enamel and the cementum is called dentin, which is less dense than enamel or cementum.

The dentin contains small hollow tubes or canals called tubules. When the dentin loses its protective covering, the tubules allow hot, cold, acidic or sticky foods to reach the nerves and cells inside the tooth.

This causes hypersensitivity and occasional discomfort but fortunately, the irritation does not cause permanent damage.

Following proper oral hygiene helps prevent the gums from receding and causing the pain of sensitive teeth.

Brushing your teeth incorrectly or even brushing too much can cause gum problems.

Your dentist will advise you on the best daily routint to maximize your oral hygiene.

Taking care of removable partial dentures

If you have removable plastic dentures, it’s important to look after them carefully.

You should brush them each day to remove food deposits and plaque. This also helps prevent them from becoming permanently stained.

It’s best to use a brush that is designed for cleaning dentures as it has bristles arranged to fit the shape of the denture. But a regular, soft-bristled toothbrush is also acceptable.

Avoid using a brush with hard bristles as these can damage the denture.

When you are handling a denture, hold them carefully. Try standing over a folded towel or a sink of water with them in case you accidentally drop them.

It’s advisable to use a denture cleanser which has the American Dental Association seal of acceptance. However hand soap or mild dishwashing liquid are also acceptable for cleaning dentures.

Other types of household cleaners and many toothpastes are too abrasive and should not be used for cleaning dentures.

A denture can lose its proper shape if it is not kept moist. So it should be placed in soaking solution or water at night � though one with metal attachments could be tarnished if placed in soaking solution.

As you age, your mouth naturally changes, which can affect the fit of the denture so, if they no longer fit properly, they should be adjusted by your dentist.

See your dentist promptly if your denture becomes loose as this can cause sores or infections.

Don’t try to adjust or repair your denture yourself as this can damage the appliance beyond repair.

When you wear a partial denture, you need to continue brushing twice a day and cleaning between your teeth daily. This will help prevent tooth decay and gum disease.

Pay special attention to cleaning the teeth that fit under the denture’s metal clasps. Plaque that becomes trapped under the clasps will increase the risk of tooth decay.

Your dentist or dental hygienist can demonstrate how to properly brush and clean between teeth.

Regular dental check-ups and having your teeth professionally cleaned are vital for maintaining a healthy smile.

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

Some women worry about whether it’s 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 dentist’s advice and ask questions if you have any concerns.

How a bridge can bring back your smile even with missing teeth

If you’re missing one or more teeth, it probably affects your smile and you may also notice a difference in chewing and speaking.

But there are options available to help you restore your smile and limit other problems.

For example, a bridge – sometimes called a fixed partial denture – replaces missing teeth with artificial teeth.

Bridges help maintain the shape of your face, as well as reducing the stress in your bite by replacing missing teeth.

They literally bridge the gap where one or more teeth may have been previously.

The restoration can be made from gold, alloys, porcelain or a combination of these materials and it is bonded onto surrounding teeth for support.

Bridges can be removable � so that you can take them out and clean them – or fixed and so can only be removed by a dentist.

An implant bridge attaches artificial teeth directly to the jaw or under the gum tissue.

Your dentist will recommend which approach is best for you.

Whatever type of bridge you choose, its success depends on its foundation. So it’s very important to keep your remaining teeth healthy and strong.

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.

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.

Choosing the right mouthwash to meet your needs

These days many people like to use a mouthwash and there is a huge range of options to choose from.

The key to choosing the right one for your needs is being clear about what you are using it for.

Many people opt for mouthwash because they want to have fresh breath.

But many mouthwashes contain alcohol which can cause the mouth to dry. It’s best to minimize the chances of suffering from dry mouth as it can increase your risk of tooth decay and gum disease.

Therefore if you want fresh breath, a breath spray or drops may meet your needs better.

Another reason for using mouthwash is when you’ve been told you have a gum disease such as gingivitis. In this case, you’ll need to choose a mouthwash that contains ingredients known to kill the bacteria that cause gingivitis.

If you like to use a mouthwash that improves your oral health, use one that contains fluoride.

Read the directions of your mouthwash and make sure you spit it out.

Don’t assume that the most expensive mouthwashes are best. Think carefully about your needs and check the ingredients.

Your dentist will be able to advise you on the best choice of mouthwash.

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, it’s 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, you’ll have a few follow-up appointments with your dentist to take care of any initial issues and to answer any questions you have.

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.

Action steps to prevent gum disease

Gum disease is a major cause of tooth loss in adults but it can be prevented or reversed if you take the right steps.

It’s caused by plaque – a sticky film of bacteria that constantly forms on the teeth. These bacteria create toxins that can damage the gums.

However, you can help avoid gum disease by caring properly for your teeth and having regular dental checkups. These are some steps you can take to keep your teeth and gums healthy:

Brush your teeth well twice a day: This removes the film of bacteria from the teeth. Be sure to use a soft-bristled toothbrush that is in good condition. Toothpastes and mouth rinses containing fluoride strengthen the teeth and help prevent decay.

Clean between your teeth every day: You need to remove the bacteria and food particles that a toothbrush can’t reach so you should clean between your teeth with floss or interdental cleaners every day. Your dentist will show you how to do this properly without injuring your gums.

Even if you already have early stage gum disease, it can often be reversed by daily brushing and flossing.

Eat a balanced diet: A good diet based on a variety of foods from the basic food groups, such as grain products; fruits; vegetables; meat, poultry and fish; and dairy products will help your teeth. It’s also a good idea to limit snacks between meals.

Visit your dentist regularly: To prevent gum disease, it’s important to have regular dental checkups and professional cleaning.

Taking the right steps will help you avoid gum disease and can even reverse it if you catch it in the early stages.
