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.

How space maintainers help children have healthy teeth

Space maintainers can be crucial to the dental health of a child.

When a child loses a baby tooth early through decay or injury, the other teeth can shift and begin to fill the vacant space.

If this happens, the problem is that, when the permanent teeth emerge, there’s not enough room for them.

This can lead to crooked or crowded teeth and difficulties with chewing or speaking.

To prevent that, the dentist can insert a space maintainer.

This holds the space left by the lost tooth until the permanent tooth emerges.

Space maintainers might be a band or a temporary crown attached to one side of the space.

When the permanent tooth emerges, the dentist removes the device and protects the child’s future smile.

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, Alzheimers 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 persons 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 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 dont 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.

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.

Tips on choosing the best dentist for you

Choosing the right dentist for your needs is one way to give you the best chance of maximizing your oral health.

If you don’t already have a dentist – or want to find one better suited to your needs – here are a few points to consider.

– Get recommendations from family, friends, neighbors or co-workers

– Ask your physician or a local pharmacist

– If you are moving to a different area, ask your current dentist for recommendations in your new location

– Contact the local or state dental society

You can also use Yellow Pages or the American Dental Association directory at www.ADA.org.

Effective dental care depends on a great relationship between the dentist and the patient so you may want to visit more than one before making your decision.

To help decide if a dentist is right for you, consider:

Is the office easy to get to from your home or job?

Are the staff helpful and friendly?

Does the office appear to be clean, tidy and well organized?

Is the appointment schedule convenient for you?

What arrangements are made for handling emergencies outside of office hours?

Does it cater for any special needs you have?

As you’ll need to work closely with your dentist in caring for your oral health, it’s worth taking time to ask questions and take notes to make sure you choose the right one for your needs.

Building a strong relationship with your dentist

You’ll give yourself the best chance of good oral health if you build a strong relationship with your dentist.

That can sometimes mean asking the right questions and helping them to assist you in the best way possible.

So you want to make sure you have a dentist who will first of all explain techniques that you should use to help prevent dental health problems. They should be willing to show you step-by-step what you need to do.

You should also choose a dentist who is willing to take time to answer your questions, especially when they are recommending a course of treatment.

If you don’t understand any part of what your dentist recommends, don’t be afraid to ask for more information.

You may want to ask if there are other options to the solution they recommend. For example:

– How do the options differ in cost?
– Which solution will last the longest?
– Do all the options solve the problem?

Ask the dentist which treatments are absolutely necessary, which are elective and Which are cosmetic.

Ask which procedures are urgently needed, and which ones are less urgent. Your dentist will help you prioritize between problems which need immediate attention and those that are less urgent.

Often, treatment can be planned over a period of time but make sure you understand any consequences of delaying treatment.

It’s naturally also important to make sure that you are given full information about fees and payment plans before treatment is scheduled.

How your oral health links with your general health

Research has shown strong links between periodontitis (advanced form of gum disease) and other health problems such as cardiovascular disease, stroke and bacterial pneumonia.

And pregnant women with periodontitis may be at increased risk of delivering pre-term and/or having babies with low birth weight.

However, just because two conditions occur at the same time, doesn’t necessarily mean that one condition causes the other. The relationship could work the other way.

For example, there is evidence that diabetics are more likely to develop periodontitis and have more severe periodontitis than non-diabetics.

Alternatively, two conditions that occur together may be caused by something else.

In addition, people who smoke or use alcohol have a higher than average risk of developing periodontitis and other conditions, including oral cancer.

Research is looking at what happens when periodontitis is treated in individuals with these problems.

The aim is to find out whether periodontitis does have an effect on other health problems.

If one caused the other, improvement in periodontal health would also improve other health problems.

While the research is not yet conclusive, the potential link between periodontitis and systemic health problems, means that preventing periodontitis may be an important step in maintaining overall health.

In most cases, good oral health can be maintained by brushing and flossing every day and receiving regular professional dental care.

Different types of fillings and restorations

Nowadays, thanks to advances in dental techniques and materials, patients have a much wider range of choices when they have to repair missing, worn, damaged or decayed teeth.

For example, materials such as ceramics and polymer compounds that look more like natural teeth help dentists create pleasing, natural-looking smiles.

The traditional materials such as gold, base metal alloys and dental amalgam are still widely used as they have many advantages.

The strength and durability of traditional dental materials continues to make them useful in many situations. For example, they are good when fillings are required in the back teeth because the pressure of chewing is high in that area.

The choice of the best option will depend on several factors such as the patient’s oral and general health, where and how the filling is placed and the number of visits needed to prepare and adjust the restored tooth.

The choice about which option is best depends on each individuals needs so you should discuss the options with your dentist.

Your saliva and why its 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.
