Periodontal (gum) diseases are sometimes called “silent” because those who have them may not experience painful symptoms. But certain signs point to the existence of these common diseases. If you are experiencing any of the symptoms below, it is time to visit our office so these problems can be treated before they lead to serious infection and loss of teeth.
Gums that bleed during the brushing of teeth. Some people think that gums bleed from brushing too hard. In fact, healthy gum tissues will not bleed with normal brushing. The usual cause of bleeding gums is an accumulation of dental plaque in the areas where your teeth meet your gums. Plaque is a film of bacteria, called a biofilm, which accumulates on your teeth. If you are not brushing and flossing effectively, plaque irritates your gum tissues and causes an inflammation and swelling called gingivitis. This causes your gums to bleed easily on contact with a toothbrush or floss.
Gum tissues that appear red and swollen. If plaque is allowed to accumulate for 24 hours or more, the inflammation in your gum tissues becomes chronic. The continuous presence of bacteria makes it impossible for your body's natural defenses to fight the infection. Chronic inflammation leads to a breakdown of the normal attachment between the teeth and the gums, causing the formation of “pockets.” Inside these pockets the infection continues to attack the tissues that support your teeth. Eventually this can lead to a breakdown of the bone that surrounds your teeth.
Bad breath. Bad breath is another sign of accumulated plaque. The bacteria in plaque may emit gases that have an unpleasant odor.
Gums that are sensitive to hot or cold. Chronic inflammation can also cause the gums to recede, exposing the roots of the teeth in which nerves may be close to the surface, leading to sensitivity to heat and cold.
Teeth that are getting loose, or a painful area in the gums. If you experience these symptoms, the infection has progressed a long way from the “silent” stage. It is time to seek immediate professional help.
If you answered “yes” to any of the above questions, a professional dental examination is in order. With daily removal of plaque by effective brushing and flossing, along with frequent professional cleanings to remove any plaque that you were unable to catch, you will go a long way to preventing periodontal disease. Also, be aware that smoking tends to mask the effects of gum disease. Generally, if you smoke your gums will not bleed when brushing or flossing, nor will they show signs of swelling.

Until recently anyone who needed to repair cavities in his or her teeth ended up with a mouth full of “silver” fillings. Dental amalgam, which has a silver appearance, was the tooth restoration material of choice. Amalgam, a combination of metals including silver, mercury, and other metals, is still used — but today there are other options that mimic the original teeth they are restoring.
You may have read about some people's concerns about the mercury used in dental amalgam. According to the American Dental Association (ADA), scientific studies have found no ill effects arising from using dental amalgam in fillings for adults or children: “While questions have arisen about the safety of dental amalgam relating to its mercury content, the major US and international scientific and health bodies, including the National Institutes of Health, the US Public Health Service, the Centers for Disease Control and Prevention, the Food and Drug Administration and the World Health Organization, among others have been satisfied that dental amalgam is a safe, reliable and effective restorative material.” Dental amalgam is still used for molars (back teeth) that must withstand heavy pressure from chewing.
For teeth that are more visible, materials that look and perform more like the original teeth — and are thus more pleasing in appearance — are now available. Dentistry is now taking a “biomimetic approach” (from words meaning “life mimicking”). The new materials — composite resins and porcelains — look like teeth because in many ways their structure imitates the biologic structure of teeth.
Composite resins are made of a plastic material (methacrylate) combined with fillers made of silica, a form of glass. They are able to bond to natural tooth structure and resemble the dentin, the inner layer of the tooth, which has a porous structure similar to bone.
Dental porcelains are a form of ceramic. They are non-metallic materials formed by the action of heat, like the ceramics used in porcelain cups and bowls. They come in a powder form that is mixed with water, shaped, and then placed in an oven until they reach the proper hardness. The end product is translucent and very hard, resembling the densely packed crystals of calcium that make up a tooth's normal outer layer, the enamel.
The old amalgam fillings required removal of tooth material to prepare a site in which they could be placed. Composite resins and porcelains can be used to treat teeth that have small or large amounts of damage to their natural substance because the materials bond directly to the remaining dentin and enamel. Thus they end up stabilizing and strengthening the restored tooth, as well as providing a natural-looking appearance.

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. DonÃ¢Â€Â™t 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.
When choosing among different ways to solve a problem, knowledge is power. In the case of selecting the best repair for a dental problem, count on your team of dental professionals to advise you. But you as the patient make the final decision, and it helps to thoroughly understand the different options, their advantages and disadvantages. If you have a chipped or broken front tooth, your likely repair options are composite resin or porcelain veneer.
Composite resins are synthetic materials that can be colored to match your natural teeth. The material is bonded to the tooth surface using adhesives that become part of the tooth structure, strengthening the original tooth. The repair looks as good as, or even better than, your original tooth. Such repairs can be used to restore small to large chips and other damage caused by decay or trauma.
Since the composite resin repair is applied directly to the tooth in the dental office, the repair can be made in a single appointment. You do not need to use a temporary repair while waiting for the final replacement to be made at a dental laboratory. This also means that the repair will cost less.
Another advantage of composite resin is that less of the healthy tooth needs to be removed to prepare the tooth to receive the replacement, since it bonds directly to the original tooth structure.
Porcelain veneers are very thin layers of tooth-colored porcelain that are also bonded to the tooth. They are usually recommended in situations with more serious injury or risk to the tooth, such as teeth that have been fractured, treated for root canal, or injured in contact sports.
Application of porcelain veneers may require more tooth preparation (in which more of the original tooth material must be removed) before the restoration can be bonded in position. Bonded porcelain veneers are likely to be longer-lasting than composite resins. They must be fabricated in a laboratory, so they require more than one visit and cost more.
All of the above are factors to consider in choosing composite resin or porcelain veneer to restore your chipped or damaged tooth. As usual in making such decisions, the final choice will depend on your individual situation.
