The power of panoramic x-rays

X-rays are extremely valuable for helping dentists identify issues that may not show up on normal oral examination.

The three most common types of dental X-rays are the bitewing, periapical and panoramic X-rays.

Panoramic X-rays give a broad overview of the entire mouth – supplying information about the teeth, upper and lower jawbone, sinuses, and other hard and soft tissues of the head and neck.

Unlike other X-rays, where the film is placed inside the patient’s mouth, the panoramic film is contained in a machine that moves around the patient’s head. So they are very easy to use.

Panoramic X-rays are often used to check wisdom teeth but they will also reveal deep cavities and gum disease. They are also useful to help patients with past or present jaw problems or those who require full or partial removable dentures, dental implants, or braces.

They can also be valuable in assisting people who are suspected of having oral cancer or have had recent trauma to the face or teeth.

Panoramic X-rays play an important role in thorough dental examinations and are recommended at least every five years or so for most patients.

Treating Sensitive Teeth

Sensitive teeth is a common problem that causes many people to feel discomfort with hot or cold foods and drinks.

It can also make it uncomfortable to brush or floss the teeth and therefore can lead to further oral problems.

However, sensitive teeth can be treated.

If you suffer from this, your dentist may suggest that you try a desensitizing toothpaste, which contains compounds that help block transmission of sensation from the tooth surface to the nerve.

For desensitizing toothpaste to work, you normally have to make several applications.

If the desensitizing toothpaste does not help, your dentist may suggest further solutions.

For example, fluoride gel – which strengthens tooth enamel and reduces the transmission of sensations – may be applied to the sensitive areas of the teeth.

If the sensitivity is caused by receding gums, your dentist may use bonding agents that “seal” the sensitive teeth.

The sealer is usually made of a plastic material.

If there is severe hypersensitivity which cannot be treated by other means, there is the option of endodontic (root canal) treatment.

Sensitive teeth is a problem that can stop you enjoying your food but is one that can often be solved.

How the food you eat can cause tooth decay

When you put food in your mouth, it immediately meets the bacteria that live there.

Plaque, for example, is a sticky film of bacteria.

These bacteria love the sugars found in many foods. So, when you don’t clean your teeth after eating, the bacteria and the sugar can combine to produce acids which can destroy the enamel – the hard surface of the tooth.

In time, this can lead to tooth decay. The more often you eat and the longer foods are in your mouth, the more damage occurs.

Many foods that are nutritious and important in our diet contain sugars – such as fruits, milk, bread, cereals and even vegetables.

So the key is not to try and avoid sugar but to think before you eat.

When you eat is also important because each time you eat food that contains sugars, the teeth are attacked by acids for 20 minutes or more.

This means that foods that are eaten as part of a meal cause less harm. More saliva is released during a meal, helping to wash foods from the mouth and reduce the effects of acids.

Here are some tips to follow when choosing your meals and snacks.
– Eat a variety of foods from different food groups
– Limit the number of snacks that you eat
– If you do snack, choose nutritious foods, such as cheese, raw vegetables, plain yogurt, or a piece of fruit

It’s also important to brush your teeth twice a day and to clean between your teeth daily with floss or interdental cleaners.

And of course regular visits to your dentist will help prevent problems from occurring and catch those that do occur while they are easier to treat.

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.

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.

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 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.

Periodontal disease: what it is and how to avoid it

Periodontal disease is an infection of the tissues that support your teeth.

There is a very slight gap (called a sulcus) between the tooth and the gum.

Periodontal diseases attack this gap and cause a breakdown in the attachment of the tooth and its supporting tissues.

When the tissues are damaged, the sulcus develops into a pocket and, as the disease gets more severe, the pocket usually gets deeper.

The two major stages of periodontal disease are gingivitis and periodontitis.

Gingivitis is a milder and reversible form of periodontal disease that only affects the gums. Gingivitis may lead to periodontitis, which is a more serious, destructive form of periodontal disease.

There are several factors that have been shown to increase the risk of developing periodontal disease:
– Systemic diseases such as diabetes
– Some types of medication
– Crooked teeth
– Bridges that no longer fit properly
– Fillings that have become defective
– Smoking
– Pregnancy

And there are a number of warning signs that can suggest a possible problem:
– Gums that bleed easily
– Red, swollen, tender gums
– Gums that have pulled away from the teeth
– Persistent bad breath or taste
– Permanent teeth that are loose or separating
– Any change in the way your teeth fit together when you bite
– Any change in the fit of partial dentures

However, it’s also possible to have periodontal disease with no warning signs.

It’s therefore important to have regular dental checkups and periodontal examinations.

If you have developed periodontal disease, the treatment will depend on how far it has progressed.

You can take steps to prevent periodontal disease from becoming more serious or recurring.

Good dental hygiene practices such as brushing twice a day, cleaning between your teeth, eating a healthy diet and having regular visits to the dentist will make a huge difference.

Why a dental abscess should be treated quickly

If you have any kind of swelling in your gum, it almost certainly indicates a serious infection that should be treated urgently.

Dental abscesses result from a bacterial infection in the teeth or gums.

For example, it may come from an untreated cavity. Cavities result when some of the bacteria in our mouths mix with sugars and starches in our diet to produce acid.

This acid attacks the hard enamel coating of our teeth and, as the cavity gets deeper, it eventually infects the nerve and blood supply of the tooth.

In some cases, a dental abscess is caused by an infection of the gum. Bone loss from gum disease can create a pocket between the tooth, gum and bone.

When bacteria and other debris get into this pocket, an abscess can form.

The treatment for an abscess depends on how severe the infection is.

If the abscess has been caused by decay, root canal treatment may be needed or the tooth may even have to be removed.

If the abscess has been caused by the gum, the gum will need deep cleaning or surgical treatment. Again the tooth may need to be removed.

Sometimes, a small incision may be made into the gum to drain the abscess. If this happens, antibiotics and pain medication may be used to relieve discomfort.

If you wait until the gum is severely swollen before seeking treatment, the situation can become very serious.

The abscess at this stage can prevent you breathing properly and can be life-threatening.

So if you have any signs of swelling in your gum, contact your dentist immediately.
