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.

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.

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.

The causes of bad breath

Bad breath – also known as halitosis – is an unpleasant condition that can cause a great deal of embarrassment.

And, for many people, its made even worse by the fact they don’t even know that they have it.

There are many possible causes for bad breath so, if you think you might have the problem, talk to your dentist.

What you eat affects what you breathe out. Certain foods, such as garlic and onions, contribute to objectionable breath odor and even dieters may develop unpleasant breath from infrequent eating.

If you don’t brush and floss daily, particles of food remain in the mouth, collecting bacteria, which can cause bad breath.

Bad breath can also be caused by dry mouth (xerostomia) which occurs when the flow of saliva decreases.

One of the reasons why its especially important to talk to your dentist about bad breath is that it may be a sign of an underlying medical problem such as respiratory tract infection or gastrointestinal problems.

Persistent bad breath or a bad taste in the mouth can also be a warning signs of gum disease.

Smoking can also cause bad breath, stain teeth and reduce your ability to taste foods.

For all these reasons, you shouldn’t put up with the problem of bad breath. Talk to your dentist and find out what might be causing the problem.
