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.

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.
If you are missing upper back teeth, contact us to schedule an appointment to evaluate your upper jaw. You can also learn more about this procedure by reading the Dear Doctor magazine article “Sinus Surgery.”
If you are dissatisfied with the way your smile looks, and your dentist is unhappy with the way your teeth fit together — but you don't like the idea of wearing braces — clear aligners may be your best solution. How much do you know about this teeth-straightening alternative? Below are some FAQs on the subject.
What do we mean by clear aligners? Clear aligners are a system for straightening teeth that uses clear plastic removable “trays” that fit over your teeth. As the teeth move to fit the trays, new trays are substituted that are designed to continue to move your teeth into the desired position. This system is an alternative to the traditional system of brackets and wires known as braces.
How can teeth be moved to new positions? The connection that holds a tooth in place in your jaws — the periodontal ligament — is not immobile. It constantly changes its position based on the normal forces of your bite. As the ligament is pushed on one side and pulled on the other, the living cells of your mouth respond by depositing bone and cementum (the protective covering of the tooth's root) on one side and dissolving it on the other. Normally this happens in a balance, maintaining your teeth in their position. We can manage these slight changes by applying constant light forces to move teeth in a predictable way.
How long does it take to move teeth to their optimum position using clear aligners? As with braces, the process is gradual. Total treatment time can range from six months to two years.
Do the trays have to be worn all the time? As you move through the sequence of trays, each is worn for 20 hours per day for two weeks. They may occasionally be removed for important social occasions.
How does an orthodontist design the sequential trays that are used? The trays are designed using a computer, based on an assessment and images of your mouth, teeth and jaws.
What kinds of problems can clear aligners correct? This method works well to correct mild to moderate crowding or spacing. If your back teeth already fit together as they should, the system may be ideal. If you have an extreme overbite or underbite, braces might work better.
Are clear aligners an alternative for everyone? Clear aligners are recommended for adults and recently, teenagers. They are not usually recommended for young children.
Why is it important to have your teeth straightened? Besides the obvious benefit of feeling better about yourself and your appearance, straight and well-aligned teeth work better. You will experience a better-functioning bite and can improve your oral health.

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.
