When speaking about veneers in dentistry, many people wonder what they are really made from and how they produce such natural results. The answer is dental porcelain...and yes, it really is a type of porcelain or glass. Even though they are made of porcelain, not all porcelains are the same. This is one reason there can be such a wide price range when comparing porcelain veneer pricing from one dentist to another. For example, the quality of the dental porcelain used and the expertise of the dental lab artisans greatly impact the price of a veneer — just like other pieces of fine art, pricing depends upon the materials used and the artistry of the person creating them.
Dental porcelains are used to create veneers because of their near ideal optical properties in mimicking natural teeth in shine, opacity, and translucence. And when you combine these facts with the artistry of the lab technician and your dentist skill's in placing the veneers, you begin to understand how veneers are virtually undetectable in cosmetically-enhanced teeth. Another reason for using dental porcelain is that they can be made in many colors, shades and translucencies to enhance the optical properties and natural beauty of whiter, brighter, and visually appealing teeth. However, do not let the word porcelain, fool you when it comes to durability. While veneers are not as strong as natural teeth they are not so fragile that you should worry about breaking or damaging them with normal wear and tear. However, you should avoid biting into extremely hard substances; using your veneers as a tool in lieu of scissors, tweezers, or pliers (you should not use your natural teeth as a tool either!); and twisting your veneers when biting into harder substances.
Periodontal (gum) disease, though it may be invisible to everyone but your dentist, can have a powerful effect on your entire body. Not only is it dangerous to your teeth and jaws, but it can increase your risk of heart attack and stroke, cause preterm births in pregnant women, and affect blood sugar control in diabetics.
Diabetics are our subject for today. Symptoms of diabetes include abnormally high levels of glucose (a form of sugar) in the blood, leading to frequent urination, excessive thirst, blurred vision, unexplained weight loss, and loss of energy. The disease can also cause severe complications in various parts of the body.
Normally, glucose, your body's main energy source, is kept under control by a hormone called insulin, which is made by an organ called the pancreas. In type 1 diabetes, a person's pancreas does not produce enough insulin to deal with all the glucose in his or her blood. In type 2 diabetes — a condition related to increased age, physical inactivity, overweight, and heredity — the pancreas may produce enough insulin, but the body is not able to use it effectively. This condition is called insulin resistance.
People with type 1 diabetes need insulin to survive. Type 2 may be treated with exercise, diet, medications, and insulin supplements.
Serious complications of diabetes range from kidney failure, blindness, and nerve damage to infections that do not heal, gangrene and amputation of limbs.
Diabetes and periodontal disease seem to have reciprocal effects on each other. Diabetics are more likely to have periodontal disease than non-diabetics; and those with periodontal disease are likely to face worsening blood sugar control over time.
Periodontal disease (from “peri”, meaning around and “odont”, meaning tooth), is caused by dental plaque — a film of bacteria that settles on your teeth and gums every day. It's what you remove with daily brushing and flossing. Any bacteria that remain cause inflammation, which can lead in the worst cases to loss of bone and eventual loss of teeth.
The close relationship of diabetes and periodontal disease probably results from changes in the function of immune cells responsible for healing. Inflammation is a part of normal wound healing — but chronic or prolonged inflammation can destroy the tissues it was meant to heal. This may be a major factor in the destructive complications of diabetes.
Many of these complications begin in the blood vessels. Like the eyes and the kidneys, gum tissues are rich in blood vessels. Gum tissues are also under constant attack from bacteria. If you are a diabetic, effective plaque control, along with regular professional dental cleaning, can have positive effects not only on periodontal disease, but also on control of your blood glucose level.

Did you know that the bacteria that cause tooth decay are usually transmitted to children from their parents, through sharing the same spoon or kissing? Once inside the child's mouth, the bacteria live on the teeth in what is called a biofilm. When the child consumes sugary foods or drinks, the bacteria act upon the sugar to produce acids that eat away at the child's teeth, producing tooth decay.
These bacteria thrive on carbohydrates such as bread, sweets, and sodas. Even fruit juices, which offer more vitamins than soda, are filled with sugars that lead to decay. The child's saliva works hard to neutralize the acidity produced from these foods, but if the child often snacks between meals this neutralization process doesnÃ¢Â€Â™t have a chance to occur.
The first sign of decay may be white spots on the teeth, an indication that minerals in the surface enamel have been dissolved in certain locations. Before it goes any farther, this process can be reversed by reducing the exposure to acids and using fluorides to strengthen the tooth surface.
Make sure your child sees a dentist by his first birthday, to provide preventive care and treat any beginning decay.
You can also help your child develop the habit of brushing his teeth with fluoridated toothpaste. It is important to use only a smear of toothpaste on the brush for very young children, and a pea-sized amount on the brush for children over the age of 2. Sometimes small children swallow their toothpaste, and excessive amounts of fluoride can cause staining on the teeth. When your children are very young, you must brush their teeth. As they get older, they can do it themselves, with your supervision. We can also apply fluoride varnish to strengthen the tooth surface and make it resistant to acids.
Brushing twice a day is a good start. But it can't prevent tooth decay when a child is eating carbohydrates all day. One way to reduce the use of sugar is to use xylitol, a naturally occurring sweetener that looks and tastes like table sugar and improves oral health. Studies have shown that use of this sweetener reduces tooth decay in children.
Another good idea is to wean children from bottles and training cups as early as possible. Sometimes children are given bottles filled with milk or sugary beverages at bedtime to help them relax. A better idea for their teeth is to teach them to drink from a regular cup filled with milk — or preferably, with water.

Do you constantly feel like you are running on empty? Do you snore, feel like napping every day, or even drink multiple cups of coffee just for the caffeine boost? You may have a sleep related breathing disorder (SRBD) or Sleep Apnea (“a” – without; “pnea” – breath) in which your airways become obstructed causing chronic loud snoring. The good news is that we can help both diagnose and treat this disorder, which means you will be able to finally get the rest that you (and your sleeping partner) so desperately need.
The reason that sleep apnea is so disruptive to daily living is that it causes awakening for a few seconds up to 50 times per night, significantly decreasing the amount of deep sleep that is necessary for full rejuvenation. Airway blockage during sleep commonly results from obesity, an enlarged tongue or tonsils, and other factors that can cause your airway to close off when you lie down, all increasing the likelihood that you will suffer from sleep apnea. These conditions are dangerous and impair the brain and heart from receiving adequate oxygen, increasing your risk for both stroke and heart attack.
The study of sleep and its disorders is relatively new. One successful way to treat sleep apnea is with a “CPAP” machine which uses a Continuous Positive Airway Pressure mask overnight to keep air passages open while sleeping. Another more comfortable, less noisy, and unobtrusive method is to use Oral Appliance Therapy, which features an appliance like a retainer that can be custom fitted to your mouth made by a dentist trained in sleep medicine.
And yes, dentists are increasingly being recruited to help study and treat sleep disorders. There are actually several ways in which we can help. Because we see our patients on a regular basis, we are uniquely qualified to diagnose early signs of SRBDs. For example, if you start to snore almost immediately after falling asleep in the dental chair, we will be able to discuss this important warning sign with you. We can also examine the back of your mouth to see if you possess any of the traits that point to SRBDs, including large tonsils and/or an elongated uvula — the tissue in the back of your throat that looks like a little punching bag.
So, if you want to stop snoring and start sleeping well or you think you may have a SRBD, call our office to schedule a basic oral exam and consultation.
