Bad breath can have a serious impact on a person's social and business life. Americans are well aware of this fact, and spend nearly $3 billion each year on gums, mints, and mouth rinses in order to make their breath “minty fresh.”
Bad breath or halitosis (from the Latin halitus, meaning exhalation, and the Greek osis, meaning a condition or disease-causing process) can originate from a number of causes; but oral bacteria are the most common source. About 600 types of bacteria grow in the average mouth. If bacteria act on materials that have been trapped in your mouth, many of them produce unpleasant odors.
Most often, bad breath starts on the back of the tongue, the largest place in the mouth for a build-up of bacteria. In this area bacteria can flourish on remnants of food, dead skin cells, and post-nasal drip. As they grow and multiply these bacteria produce chemical products called volatile sulfur compounds or VSCs. These compounds emit smells of decay reminiscent of rotten eggs.
In addition to bacteria on the tongue, halitosis may come from periodontal (gum) disease, tooth decay, or other dental problems. If you have halitosis, it is thus important to have a dental examination and assessment, and to treat any such problems that are found. Treating bacteria on the tongue without treating underlying periodontal disease will only temporarily cure bad breath.
The next step is to take control of tongue bacteria by brushing or scraping your tongue, with possible addition of antiseptic mouth rinses. People who have bad breath have more coating on their tongues than those who don't, and regularly cleaning the surface of the tongue has been demonstrated to reduce bad breath.
Implements have been designed specifically for the purpose of scraping or brushing the surface of the tongue. Using a toothbrush is not as effective because it is designed to clean the hard tooth surface, rather than the spongy surface of the tongue. To keep your breath fresh, you must regularly remove the coating from your tongue. This means acquiring a tongue scraper or brush and using it every day.

Gum disease (gingivitis) and tooth decay are primarily caused by dental plaque. Dental plaque is a whitish, sticky film that accumulates daily along the gumline and on the surfaces of your teeth. Composed of bacteria, it is controllable through good oral hygiene habits — most importantly, effective brushing.
Controlling plaque and preventing gingivitis and tooth decay will make it more likely that you keep your teeth through your lifetime and will also improve your general health. Scientific studies have linked gum disease and diseases of the heart and circulatory system.
“I know how to brush my teeth. I've been doing it since I was a toddler,” you may be saying. But you may not be performing this daily ritual in the most effective way.
Let's take another look at tooth brushing. First, your grip: Hold the brush in your fingertips with a light pressure. Position the brush so the bristles are at a 45 degree angle to your gumline, and then brush with a gentle scrubbing motion. Donât scrub too hard, or you may damage your sensitive gum tissue.
Some electric brushes can remove plaque more quickly than a regular hand-held brush, but if you brush well any kind of brush works. A brush will last several months. Get a new one when the bristles become worn or splayed out.
Use a toothpaste that contains fluoride. When used consistently, fluoride toothpastes make your teeth more resistant to decay. Spit out the toothpaste after brushing, but don't rinse or you will wash the fluoride away.
After brushing, complete your cleaning job by using floss to clean between your teeth where the brush does not reach. Wrap it in a “C” shape around each tooth and move it vertically up and down, removing plaque from the tooth surfaces where your teeth meet. You can also use an antibacterial mouth rinse.
Thoroughly clean your teeth at least once a day, brushing and flossing. A plaque film takes 12 to 24 hours to form itself again.
To be certain you are brushing correctly, ask our office or one of our hygienists to demonstrate brushing techniques for you in your own mouth. You can also assess the quality of your brushing technique by checking with your tongue after brushing to make sure your tooth surfaces feel smooth and slick. Your gums should not bleed after brushing. Bleeding is a sign of infection. If you have a habit of consistent brushing but your gums continue to bleed, it's time for a visit to our office.
Why is it important to replace missing teeth with restorations such as dental implants? You might be surprised to find that the damage caused by missing teeth is much greater than the simple gaps left in your smile.
As the years go by, teeth lost early in adulthood cause structural changes in a person's face. By age 45 changes in facial structure are already visible in the form of sunken cheeks. By 60, cheeks and lips lose their support, resulting in an aging look. This process continues and if the teeth are not replaced, much of the structural support of the person's face is lost.
These changes are caused by loss of bone. Although it may seem static, bone is actually living tissue that needs constant stimulation to maintain its form and density. With normal stimulation it is in a constant state of resorption (breaking down) and deposition (building up). Teeth provide the needed stimulation for the bone that surrounds them (called alveolar bone) as they meet each other during biting, chewing, and speech. When the stimulation continues, the bone continues to rebuild itself. Without this stimulation, the bone resorbs, does not build up again, and loses substance.
Without stimulation, alveolar bone loses width, height, and volume. Since your teeth and their surrounding bone support your chin, cheeks, and lips, this has a powerful effect on your appearance. It may also affect your ability to chew and to speak.
As alveolar bone diminishes, the next layer of bone also begins to resorb. This is the bone of the jaw itself. The lower part of the face begins to collapse, and the cheeks become hollow. This effect is especially noticeable for people with no teeth (edentulous).
Usually the first tooth to be lost, due to infection and decay, is a molar (back tooth). In the past, a missing single back tooth was frequently replaced by a fixed partial denture (FPD). A crown is provided for each of the two teeth on the sides of the gap, called abutment teeth, to support a false tooth in the middle. However, if they are not well cared for, the abutment teeth may be the next to succumb to decay.
Today the treatment of choice is an implant. A dental implant is a tooth-root replacement made of titanium, which fuses with the bone — making it very stable. Above the gums it is covered by a crown that looks like a natural tooth. The benefit of the implant is that it continues to provide stimulation to the alveolar bone, preventing bone loss.
Implants are also a good choice in the case of multiple missing teeth. They can be used to support bridges or false teeth (dentures). The results are an improved, younger appearance and better functionality.

Of all the of amazing procedures in today's dentistry, surgery that causes new bone to grow — in places where it had previously been lost — is high on the list of the most extraordinary. (When bone is lost or resorbed, it is broken down into its mineral components, which are dissolved into the bloodstream. Resorption of tooth-supporting bone often takes place after teeth are lost.) Dental techniques that cause new bone growth are important because a certain amount of bone is needed to replace lost teeth with dental implants.
Today's dental implants themselves are an amazing innovation. Implants consist of a replacement for the tooth's root, usually made of a metal called titanium. A replacement for the crown, the part of the tooth that is visible above the gums, is attached to the titanium root. Titanium has the remarkable quality of being able to fuse with the bone in which it is anchored. This process, first discovered in the 1950s, is called osseointegration.
In the case of missing upper back teeth, many people who wanted dental implants in the past were told that they did not have enough bone to anchor the implants and that they had to get removable dentures instead.
But now a new surgery called maxillary sinus augmentation can cause your body to regenerate bone where it was lost and is needed to anchor dental implants.
Bone in the upper jaw or maxilla usually supports your upper back teeth. Inside the maxilla, on either side of your upper jaw, are air spaces in the bone, which are lined with a membrane. These spaces, called the maxillary sinuses, are generally shaped like pyramids; but their shape and size is different in each person. The new surgical procedures involve lifting up the sinus membrane in the area where bone is needed and filling the space thus created with a bone grafting material. Your body then creates new bone to fill the space. This usually takes about six months. If you have almost enough bone to stabilize the implants, they can be placed simultaneously with the graft, thus saving time and avoiding a second surgical procedure.
All grafting materials used today are approved by the Food and Drug Administration (FDA) and must be prepared according to their guidelines. They are specially treated to render them completely safe for human use.
After the surgery there is usually no more than mild to moderate swelling and some discomfort, about the same as having a tooth removed.
