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.

Root canal treatment

Root canal therapy is an important treatment that can save a tooth with a diseased nerve and which in the past would probably have needed to be removed.

Inside each tooth is the ‘pulp’ which runs like a thread down through the root and provides nutrients and nerves to the tooth. It is the soft tissue that contains nerves, blood vessels and connective tissue.

If the pulp is diseased or injured, the pulp tissue dies.

The most common cause of pulp death is a cracked tooth or a deep cavity. Both of these problems can let bacteria enter the pulp.

So, if you don’t remove it, your tooth gets infected and you could lose it.

After the dentist – or periodontist (a dentist who specializes in problems of the pulp) – removes the pulp, the root canal is cleaned and sealed off to protect it. Then your dentist places a crown over the tooth to help make it stronger.

Most of the time, a root canal is a relatively simple procedure involving one to three visits with little or no discomfort.

Your restored tooth could last a lifetime, if you continue to care for your teeth and gums and enjoy regular checkups.

What’s involved in getting a dental implant?

Dental implants are increasingly popular as a way to replace missing or damaged teeth.

Their great advantage is that they look natural and feel secure helping you to restore your smile and eat more easily.

Implants are an ideal solution for many people but they are not an option for everyone.

Placing implants requires some surgery so patients must be in good health, have healthy gums and have adequate bone to support the implant.

They must also be committed to taking action to maintain their oral hygiene and to visiting the dentist regularly.

The process for placing implants is as follows:

First, surgery is performed to place the anchor. This can take up to several hours. Following the surgery, you may need to wait up to six months for the bone to grow around the anchor and firmly hold it in place. Sometimes follow up surgery is required to attach a post to connect the anchor to the replacement teeth. Alternatively, the anchor and post may already be attached and are placed at the same time.

After the gums have had several weeks to heal, the next step is to fit specially-made artificial teeth to the post portion of the anchor. This can take a few weeks to complete as several fittings may be required.

Implant surgery can be done either in a dental office or in a hospital, depending upon a number of factors. A local or general anesthetic may be used. Usually pain medications and, when necessary, antibiotics are prescribed.

After your implants are fitted, your dentist will give you tips and advice on maintaining your oral hygiene.

Your dentist can help you decide whether you would be a good candidate for implants.

Diagnosing jaw problems and pains – TMD and TMJ

More than fifteen percent of American adults suffer from chronic facial pain.

Common symptoms can include pain in or around the ear, tenderness of the jaw, clicking or popping noises when opening the mouth or even head and neck aches.

There are two joints and several jaw muscles which make it possible to open and close the mouth. They work together when you chew, speak, and swallow.

These structures include muscles and ligaments, as well as the jaw bone, the mandible (lower jaw) with two joints, the TMJ’s.

The TM joint is one of the most complex joints in the body. Located on each side of the head, these joints work together and can make many different movements, including a combination of rotating and gliding action when chewing and speaking.

Several muscles help open and close the mouth. They control the lower jaw (mandible) as it moves forward, backward, and side-to-side.

Both TM joints are involved in these movements. Each TM joint has a disc between the ball and socket. The disc cushions the load while enabling the jaw to open widely and perform rotating and transnational movements.

Any problem that prevents this complex system of muscles, ligaments, discs and bones from working together properly may result in a painful TMJ disorder.

If you are suffering from this type of pain, your dentist can help identify its source with a thorough exam and appropriate x-rays.

Often, the problem is a sinus or toothache or it could be an early stage of periodontal disease.

But for some pain, the cause is not so easily diagnosed.

The pain could be related to the facial muscles, the jaw or mandibular joint, located in the front of the ear.

Treatments for this pain may include stress reducing exercises, muscle relaxants, or wearing a mouth protector to prevent teeth grinding.
They’ve been successful for many and your dentist can recommend which is best for you.

Taking care of your dentures

Your dentures are designed to last a very long time so it’s important that you take care of them as you would take care of your own teeth.

They are very delicate and may break easily if dropped even a few inches. So it’s a good idea to stand over a folded towel or a basin of water when handling dentures.

When you are not wearing your dentures, store them away from children and pets.

Like natural teeth, dentures must be brushed daily to remove food deposits and plaque.

Brushing helps prevent dentures from becoming permanently stained and helps your mouth stay healthy.

There are special brushes designed for cleaning dentures but a toothbrush with soft bristles can also be used. Avoid using hard-bristled brushes as these can damage your dentures.

Some denture wearers also use hand soap or mild dish washing liquid for cleaning and that’s fine. But avoid using powdered household cleansers, which may be too abrasive. Also, avoid using bleach, as this may whiten the pink portion of the denture.

The first step in cleaning dentures is to rinse away loose food particles thoroughly. Moisten the brush and apply denture cleanser. Brush every surface, scrubbing gently to avoid damage.

Dentures may lose their shape if they are allowed to dry out. When they are not worn, dentures should be placed in a denture cleanser soaking solution or in water. Never place dentures in hot water, which could cause them to warp.

Ultrasonic cleaners are also used to care for dentures. However, using an ultrasonic cleaner does not replace a thorough daily brushing.

You can seriously damage your dentures by trying to adjust or repair them yourself. So see your dentist if your dentures break, crack, chip or if one of the teeth becomes loose.

Over time, dentures will need to be relined, re based, or remade due to normal wear. They may also need to be replaced if they become loose and the teeth show signs of significant wear.

You need to make regular visits to your dentist to make sure the dentures are working as well as possible for you and to check for more serious problems in your mouth such as oral cancer.

Understanding your wisdom teeth

Many patients ask whether wisdom teeth are really necessary since so many people have them removed.

The fact is that wisdom teeth are a valuable asset to the mouth when they are healthy and properly positioned.

However, problems can occur that sometimes make it better to have them removed.

For example, when the jaw isn’t large enough, the wisdom teeth can become impacted – misaligned or unable to grow in properly. They may grow sideways, emerge only part way from the gum or remain trapped beneath the gum and bone.

The reasons wisdom teeth may have to be extracted include:
– The teeth have only partially erupted. This leaves an opening for bacteria which cause infection.
– There is a chance the wisdom teeth will damage adjacent teeth.
– A cyst forms which may destroy surrounding structures such as bone or tooth roots.

Ask your dentist about the health and positioning of your wisdom teeth.

Your dentist will tell you if there are any issues and will recommend any steps needed.

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.

Making your teeth look better with veneers

Everybody wants the best smile possible and there’s no need to have it spoiled by gaps in your teeth or by teeth that are stained or badly shaped.

Whether the problem was caused by nature or by an injury, you may be able to have a veneer placed on top of your teeth to restore or improve your smile.

Veneers are thin, custom-made shells crafted from tooth-colored materials designed to cover the front side of teeth.

Your dentist will usually make a model of your teeth and the veneers will be made by a specialist dental technician.

A small amount of enamel has to be removed from your teeth to accommodate the shell so having veneers is usually an irreversible process.

In order to make the most of your veneer, your dentist may suggest that you avoid foods and drinks that could discolor them, such as coffee, tea or red wine.

It’s also possible that veneers might chip or fracture.

But, for many people, veneers are well worth it as they give them a completely new smile.

Root canal treatment

Root canal therapy is an important treatment that can save a tooth with a diseased nerve and which in the past would probably have needed to be removed.

Inside each tooth is the ‘pulp’ which runs like a thread down through the root and provides nutrients and nerves to the tooth. It is the soft tissue that contains nerves, blood vessels and connective tissue.

If the pulp is diseased or injured, the pulp tissue dies.

The most common cause of pulp death is a cracked tooth or a deep cavity. Both of these problems can let bacteria enter the pulp.

So, if you don’t remove it, your tooth gets infected and you could lose it.

After the dentist – or endodontist (a dentist who specializes in problems of the pulp) – removes the pulp, the root canal is cleaned and sealed off to protect it. Then your dentist places a crown over the tooth to help make it stronger.

Most of the time, a root canal is a relatively simple procedure involving one to three visits with little or no discomfort.

Your restored tooth could last a lifetime, if you continue to care for your teeth and gums and enjoy regular checkups.

Different types of dentist and how they help your oral care

While many people see dentists as the single group of people who look after the health of your teeth and mouth, there are various specialist categories that help you in different ways.

The categorization of a dentist will depend on their education, training and experience.

Here are some of the main specialist areas of dentistry:

Endodontics: Concerned with the dental pulp – the part in the center of a tooth made up of living soft tissue and cells and root canal therapy

Oral and Maxillofacial Pathology: This deals with the identification, and management of diseases affecting the oral and maxillofacial regions

Oral and Maxillofacial Radiology: Deals with the production and interpretation of images and data produced by radiant energy that are used for the diagnosis and management of diseases, disorders and conditions of the oral and maxillofacial region

Oral and Maxillofacial Surgery: Diagnosis and surgical treatment of diseases, injuries and defects of the tissues including extractions, facial surgery and implants

Orthodontics and Dentofacial Orthopaedics: Mainly deals with diagnosis, prevention and treatment of misaligned teeth and modification of midface and mandibular growth

Pediatric Dentistry: Provides preventive and therapeutic oral health care for infants and children through adolescence.

Periodontics: Prevention, diagnosis and treatment of diseases of the supporting and surrounding tissues of the teeth and the maintenance of the health, function and esthetics of these structures and tissues. Most periodonitist place implants

Prosthodontics: Diagnosis, treatment planning, rehabilitation and maintenance associated with missing or deficient teeth and/or oral and maxillofacial tissues. Includes dentures, bridges and the restoration of implants.

Plus, of course, general dentists provide everyday care and many specialist services to maintain your oral health.

What to expect when having a tooth extracted

The process of having a tooth extracted may seem worrying but you’ll find it much easier if you know what to expect on the day and afterwards.

Your dentist will make the process as comfortable as possible for you by numbing the area around the tooth to be extracted.

In most cases, a small amount of bleeding is quite normal and your dentist will advise you what process to follow to allow healing as quickly as possible.

Generally, you should avoid anything that might prevent normal healing.

For example, it’s best not to smoke, rinse your mouth vigorously or drink through a straw for 24 hours afterwards as these could delay healing.

For the first few days, if you need to rinse your mouth, do it gently. If you are suffering pain or swelling, apply a cold cloth or an ice bag.

If necessary, your dentist will recommend something for any pain.

At the beginning, don’t clean around the socket where the tooth has been removed but you should brush and floss the other teeth as usual.

Modern procedures make having an extraction and the follow-up more comfortable than ever before.

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 dental implants can give you a better smile

If you have missing teeth, you dont just have to rely on crowns, conventional bridges and dentures.

Many people are now choosing dental implants as the best way to restore their smile and solve dental problems.

Implants are placed below the gums during a series of appointments. They fuse to the jawbone and provide a base for individual replacement teeth, bridges or a denture.

As they are fused to the bone, they offer greater stability. And, because they are integrated into your jaw, your replacement teeth will feel more natural.

This secure fit often also makes them more comfortable than other solutions.

In order to have implants, you need to have healthy gums and adequate bone to support the implant.

To find out whether you could be a candidate for dental implants, talk to your dentist about what they could do for you.

Why dry mouth can be a problem and what to do about it

Your saliva plays an important role in your oral health and reduced saliva flow can lead to health problems.

Reduced saliva flow can lead to a dry mouth and this is a common problem among older adults.

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

Dry mouth can be associated with various problems such as a constant sore throat, burning sensation, problems speaking, difficulty swallowing, hoarseness or dry nasal passages.

Drying irritates the soft tissues in the mouth, which can make them inflamed and more susceptible to infection. Without the cleansing effects of saliva, tooth decay and other oral health problems become more common.

So, if dry mouth is not treated, it can damage your teeth.

Without adequate saliva to lubricate your mouth, wash away food, and neutralize the acids produced by plaque, extensive decay can occur.

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