An abscessed tooth is a pocket of pus, usually caused by some kind of infection and the spread of bacteria from the root of the tooth to the tissue just below or near the tooth.

In general, a tooth that has become abscessed is one whose underlying pulp (the tooth’s soft core) has become infected or swollen. The pulp contains nerves, blood vessels and connective tissue, and lies within the tooth. It extends from the crown of the tooth, to the tip of the root, in the bone of the jaws.

An abscessed tooth can be an extremely painful condition.

In some cases, antibiotics are administered in an attempt to kill an infection. If antibiotics are ineffective and an abscess is shown to be damaging the pulp or lower bony structures, a root canal procedure may be needed to remove the dead pulp and restore the tooth to a healthy state

Americans spend more than $1 billion a year on over the counter halitosis products, many of which are ineffective because they only mask the problem.

What causes bad breath?

Bad breath is caused by a variety of factors. In most cases, it is caused by food remaining in the mouth – on the teeth, tongue, gums, and other structures, collecting bacteria. Dead and dying bacterial cells release a sulfur compound that gives your breath an unpleasant odor. Certain foods, such as garlic and onions, contribute to breath odor. Once the food is absorbed into the bloodstream, it is transferred to the lungs, where it is exhaled. Brushing, flossing and mouthwash only mask the odor. Dieters sometimes develop unpleasant breath from fasting.

Periodontal (gum) disease often causes persistent bad breath or a bad taste in the mouth, and persistent bad breath may mean a sign that you have gum disease.

Gum disease is caused by plaque – the sticky, often colorless, film of bacteria that constantly forms on teeth. Dry mouth or xerostomia may also cause bad breath due to decreased salivary flow. Saliva cleans your mouth and removes particles that may cause odor. Tobacco products cause bad breath, stain teeth, reduce your ability to taste foods and irritate your gum tissues. Bad breath may also be a sign that you have a serious health problem, such as a respiratory tract infection, chronic sinusitis, postnasal drip, chronic bronchitis, diabetes, gastrointestinal disturbance, liver or kidney ailment.

Here are characteristic bad breath odors associated with some of these illnesses:

Diabetes – acetone, fruity

Liver failure – sweetish, musty

Acute rheumatic fever – acid, sweet

Lung abscess – foul, putrefactive

Blood dyscrasias – resembling decomposed blood

Liver cirrhosis – resembling decayed blood

Uremia – ammonia or urine

Hand-Schuller-Christian disease – fetid breath and unpleasant taste

Scurvy – foul breath from stomach inflammation

Wegner`s granulomatosis – Necrotic, putrefactive

Kidney failure – ammonia or urine

Diphtheria, dysentery, measles, pneumonia, scarlet fever, tuberculosis – extremely foul, fetid odor

Syphilis – fetid

Bad breath may also be caused by medications you are taking, including central nervous system agents, anti-Parkinson drugs, antihistamines/decongestants, anti-psychotics, anti-cholinergics, narcotics, anti-hypertensives, and anti-depressants.

Caring for bad breath

Daily brushing and flossing, and regular professional cleanings, will normally take care of unpleasant breath. And don’t forget your often overlooked tongue as a culprit for bad breath. Bacterial plaque and food debris also can accumulate on the back of the tongue. The tongue’s surface is extremely rough and bacteria can accumulate easily in the cracks and crevices.

Controlling periodontal disease and maintaining good oral health helps to reduce bad breath. If you have constant bad breath, make a list of the foods you eat and any medications you take. Some medications may contribute to bad breath.

Improperly cleaned dentures can also harbor odor-causing bacteria and food particles. If you wear removable dentures, take them out at night and clean them thoroughly before replacing them.

If your dentist determines that your mouth is healthy and that the odor is not oral in nature, you may be referred to your family physician or to a specialist to determine the cause of the odor and possible treatment. If the odor is due to gum disease, your dentist can either treat the disease or refer you to a periodontist, a specialist in treating gum tissues. Gum disease can cause gum tissues to pull away from the teeth and form pockets. When these pockets are deep, only a professional periodontal cleaning can remove the bacteria and plaque that accumulate.

Mouthwashes are generally ineffective on bad breath. If your bad breath persists even after good oral hygiene, there are special products your dentist may prescribe, including Zytex, which is a combination of zinc chloride, thymol and eucalyptus oil that neutralizes the sulfur compounds and kills the bacteria that causes them. In addition, a special antimicrobial mouth rinse may be prescribed. An example is chlorhexidine, but be careful not to use it for more than a few months as it can stain your teeth. Some antiseptic mouth rinses have been accepted by the American Dental Association for their breath freshening properties and therapeutic benefits in reducing plaque and gingivitis. Instead of simply masking breath odor, these products have been demonstrated to kill the germs that cause bad breath. Ask your dentist about trying some of these products.

For example, repeated episodes of vomiting, which is common in people with bulimia, release harmful stomach acids that pass through the mouth and can erode tooth enamel, causing cavities, discoloration and tooth loss. Other problems, such as poorly fitting fillings and braces, are another byproduct of such eating disorders.

Brushing after episodic vomiting is actually more harmful than one would think. The best practice is to rinse thoroughly with a neutral solution such as baking soda and water.

A canker sore is typically one that occurs on the delicate tissues inside your mouth. It is usually light-colored at its base and can have a red exterior border.

A cold sore or fever blister, on the other hand, usually occurs on the outside of the mouth, usually on or near the nose or lips. A cold sore is contagious because it is caused by the herpes simplex virus, and it is usually painful and filled with fluid.

In most cases, patience is the best medicine for treating canker sores. A healthy diet and good oral hygiene are usually the best remedy, but some special rinses and anesthetics can help. Cold sores can be treated effectively with some over-the-counter topical creams; sometimes, an antiviral medication will be prescribed by your doctor.

Tooth decay is caused by a variety of things; in medical terms, cavities are called caries, which are caused by long-term destructive forces acting on tooth structures such as enamel and the tooth’s inner dentin material.

These destructive forces include frequent exposure to foods rich in sugar and carbohydrates. Soda, candy, ice cream—even milk—are common culprits. Left inside your mouth from non-brushing and flossing, these materials break down quickly, allowing bacteria to do their dirty work in the form of a harmful, colorless sticky substance called plaque.

The plaque works in concert with leftover food particles in your mouth to form harmful acids that destroy enamel and other tooth structures.

If cavities aren’t treated early enough, they can lead to more serious problems requiring treatments such as root canal therapy.

Preventing Cavities

The best defense against cavities is good oral hygiene, including brushing with a fluoride toothpaste, flossing and rinsing. Your body’s own saliva is also an excellent cavity fighter, because it contains special chemicals that rinse away many harmful materials. Chewing a good sugarless gum will stimulate saliva production between brushing.

Special sealants and varnishes can also be applied to stave off cavities from forming.

If you have any of the following symptoms, you may have a cavity:

Unusual sensitivity to hot and cold water or foods.
A localized pain in your tooth or near the gum line.
Teeth that change color.
Baby Bottle Tooth Decay

Baby bottle tooth decay is caused by sugary substances in breast milk and some juices, which combine with saliva to form pools inside the baby’s mouth.

If left untreated, this can lead to premature decay of your baby’s future primary teeth, which can later hamper the proper formation of permanent teeth.

One of the best ways to avoid baby bottle tooth decay is to not allow your baby to nurse on a bottle while going to sleep. Encouraging your toddler to drink from a cup as early as possible will also help stave off the problems associated with baby bottle tooth decay.

Broken, Fractured, or Displaced Tooth

A broken, fractured or displaced tooth is usually not a cause for alarm, as long as decisive, quick action is taken.

If the tooth has been knocked out, try to place the tooth back in its socket while waiting to see your dentist.

First, rinse the mouth of any blood or other debris and place a cold cloth or compress on the cheek near the injury. This will keep down swelling.

If you cannot locate the tooth back in its socket, hold the dislocated tooth by the crown – not the root. Next, place it in a container of warm milk, saline or the victim’s own saliva and keep it in the solution until you arrive at the emergency room or dentist’s office.

For a fractured tooth, it is best to rinse with warm water and again, apply a cold pack or compress. Ibuprofen may be used to help keep down swelling.

If the tooth fracture is minor, the tooth can be sanded or if necessary, restored by the dentist if the pulp is not severely damaged.

If a child’s primary tooth has been loosened by an injury or an emerging permanent tooth, try getting the child to gently bite down on an apple or piece of caramel; in some cases, the tooth will easily separate from the gum.

Infections and other problems such as receding gums and gum disease, or periodontal disease, are common afflictions among diabetics for many reasons; for instance, diabetics often are plagued by diminished saliva production, which can hamper the proper cleansing of cavity-causing debris and bacteria from the mouth. In addition, blood sugar levels that are out of balance could lead to problems that promote cavities and gum disease.

As with any condition, good oral hygiene, including regular brushing, flossing and rinsing, as well as the proper diabetic diet, will go a long way in preventing needless problems

Some of the less alarming results of dry mouth include bad breath. But dry mouth can lead to more serious problems, including burning tongue syndrome, a painful condition caused by lack of moisture on the tongue.

If dry mouth isn’t readily apparent, you may experience other conditions that dry mouth can cause, including an overly-sensitive tongue, chronic thirst or even difficulty in speaking.

If you don’t have a medical condition that causes it, dry mouth can be minimized by sipping water regularly, chewing sugarless gum and avoiding smoking. Of course, there is no substitute for regular checkups and good oral hygiene.

But sometimes, fluorosis occurs when fluoride-containing toothpastes or rinses are swallowed, instead of expelled.

Fluorosis causes a number of aesthetic problems, including abnormally darkened or stained teeth. While such problems are generally harmless to your health, they can create concerns with your appearance.

Gum disease originates in the gums, where infections form from harmful bacteria and other materials left behind from eating. Early warning signs include chronic bad breath, tender or painful swollen gums and minor bleeding after brushing or flossing. In many cases, however, gingivitis can go unnoticed. The infections can eventually cause the gums to separate from the teeth, creating even greater opportunities for infection and decay.

Although gum disease is the major cause of tooth loss in adults, in many cases it is avoidable.

If gingivitis goes untreated, more serious problems such as abscesses, bone loss or periodontitis can occur.

Periodontitis is treated in a number of ways. One method, called root planing, involved cleaning and scraping below the gum line to smooth the roots. If effective, this procedure helps the gums reattach themselves to the tooth structure. However, not all instances of scaling and root planing successfully reattach the tooth to the gums. Additional measures may be needed if the periodontal pockets persist after scaling and root planing

Pregnancy has also been known to cause a form of gingivitis. This has been linked to hormonal changes in the woman’s body that promote plaque production.
