Guidelines regarding the concentration of fluoride in water have recently been changed by the US Government's Department of Health and Human Services (HHS) and the Environmental Protection Agency (EPA). These agencies recommended a reduction of fluoride in water supplies to 0.7mg/L, modifying the original recommendations provided in 1962 by the US Public Health Service.
What is fluoride, and why add it to water supplies?
Fluoride is a chemical form of fluorine, a naturally occurring element. For decades, scientists have carried out studies on the effects of fluoride in water, and they have proved that fluoride strengthens tooth surfaces and makes them resistant to decay. A fluoride concentration of about one milligram per liter (1 mg/L), or 1 part per million (1ppm), in the water supply is associated with substantially fewer cavities. This concentration of fluoride (equivalent to a grain of salt in a gallon of water) has been found to have no negative health effects.
The Center for Disease Control (CDC) says that fluoridated water is one of the ten most effective public health measures of the 20th Century. The optimal amount of fluoride necessary to make teeth resistant to decay turns out to be between 0.7 and 1.20 milligrams per liter (mg/L). A certain amount of fluoride occurs naturally in water supplies, and communities have added fluoride to bring the amount up to the optimal recommendations.
How does fluoride you drink get into your teeth?
The fluoride you drink in your water is deposited in your bones. Bone is an active living substance that is constantly broken down and rebuilt as a normal body process. As this happens the fluoride is released into the blood, from which it can enter the saliva and act on the tooth surface.
What about fluoride from other sources?
Americans now have access to many sources of fluoride in addition to the water they drink. These include foods, beverages and toothpaste. As a result, dentists have begun to notice an increased prevalence of a condition known as Dental Fluorosis.
What is Dental Fluorosis?
Dental Fluorosis can occur when teeth, particularly in children, receive too much fluoride. This condition is a mottling or uneven staining of the tooth surface enamel. There may be small white spots or extensive brownish discolorations. The mottled enamel is still resistant to decay, but it may be unattractive in appearance.
What is the idea behind the new guidelines?
With the new guidelines, fluoride is kept at the lower end of the scale of the optimal concentration for strengthening teeth against decay. At this end, there is room to add consumption of fluoride from other sources such as foods or toothpaste. In short, it is the best of both worlds.

There's a lot to like about dental implants, today's state-of-the-art tooth-replacement system. We consider them the best choice for replacing missing teeth because implants are:
You may not realize this, but when a tooth is missing, the bone underneath it begins to melt away. That's because bone needs constant stimulation to rebuild itself and stay healthy, and it receives this stimulation from teeth. It's a delicate balance that's disrupted by the loss of even one tooth. Because implants are made of biocompatible titanium, they actually fuse to the bone and prevent bone loss.
The fusion of implant to bone is an extremely solid connection. Not only does it offer a strong replacement for a missing tooth, but it can also offer support to other tooth-replacement methods such as fixed bridges or dentures. By themselves, these other methods would not preserve bone and might even hasten its loss in the case of dentures. But with implants, bone-loss is prevented — as is embarrassing and uncomfortable slippage of dentures.
When you receive your implant, it is left alone for a few months to complete the fusion process described above. Then it is topped with a crown made of a realistic tooth-like material. The result is so convincing as a tooth replacement, only you and your dentist may be able to tell it's not a natural tooth.
Dental implants have an amazing success rate — over 97%. And once they fuse to the jawbone, they should never need replacement. In fact, they will likely outlast the crowns to which they are attached, but this is not a problem. Implant crowns are precision components that detach for easy replacement, should the need arise.
Implants have a higher initial cost than other forms of tooth replacement, but when you consider how long they last, they are very economical. Consider it an investment in your health, appearance and self-confidence.

Sleeping disorders impact people in different ways. For some people, they may feel they do not have a problem — except for the fact that their sleeping partner complains about their snoring. For others, they may know they have a snoring issue because they constantly wake themselves up gasping for air. This is a dangerous condition known as Obstructive Sleep Apnea OSA (“a” – without; “pnea” – breath). If any of these scenarios sound like your experience, then you may have OSA or another type of Sleep Related Breathing Disorder (SRBD). However, before jumping to conclusions, you need to obtain a thorough examination from a primary-care physician who is trained in sleep medicine in conjunction with our office. We have received training in the diagnosis and treatment of sleep disorders. But the good news is that sleep apnea is a treatable condition.
As for your question, yes, there are many things we can do to treat your snoring after the cause of your problem is properly established. One helpful approach is through the use of a specially designed oral appliance that we custom make and fit to your mouth. It is easy to use during sleep. Once in place, it will keep your lower jaw in a forward position so that your tongue is held forward to stop blocking your upper airway (i.e. the back of your throat and area causing your snoring and hindering your breathing while you sleep). Another option is to use a Continuous Positive Airway Pressure (CPAP) machine. This specialized machine requires you to sleep with a mask that covers your mouth and/or nose. While you sleep, it delivers continuous pressure to your windpipe so that your tongue is forced away from your airway.
If your snoring is keeping you or your loved ones awake, we are a good place to start. Contact us today to discuss your questions about snoring or to schedule an appointment. You can also learn more about snoring and sleep disorders when you continue reading the Dear Doctor magazine article “Sleep Disorders & Dentistry.”
A generation ago, hearing the term, “smile makeover,” would most likely have resulted in questions and puzzled looks. However, through the power of both the media and celebrities, today it has become a common household term with over 70% of all inquiries coming from people in the 31 to 50 year old age group, according to the American Academy of Cosmetic Dentistry (AACD). While some people seek cosmetic dentistry purely to boost their self-esteem, others pursue it to improve first impressions during business and social interactions, as many studies have revealed that first impressions are the ones that typically last the longest.
The AACD study also revealed other interesting statistics that support why a smile makeover is a wise choice that can yield a life-changing return on your investment — you!
Another important study recently conducted by Beall Research & Training, Inc., an independent marketing research firm, used before and after photos of smile makeovers for polling purposes. The research found that people who have had a smile makeover are viewed by others as more attractive, intelligent, happy, successful in their career, friendly, interesting, kind, wealthy, and appealing to the opposite sex. This evidence clearly proves just how important a first impression can be as well as what it can silently communicate about you.

It can start with a simple twinge or be as severe as excruciating pain. From time to time, we have patients asking questions about tooth sensitivity — what causes it? What can be done about it? For these reasons, we have put together the following list of frequently asked questions (FAQs) so that you can develop a healthy understanding about this painful and often avoidable condition.
The first layer of protection of the teeth is enamel. Enamel is a dense crystalline structure, the hardest substance produced by animals. It is an inert substance that has no nerve supply and thus it protects the teeth from temperature and pressure changes. When it is compromised, worn thin, or exposed due to gum recession, it leaves the dentin exposed and vulnerable. Unlike enamel, dentin is living and has delicate nerve fibers within it.
Once dentin is exposed, it can become sensitive. It typically occurs when the dentin comes in contact with heat, cold, or the “double whammy” combination of both cold and sweets. Even the bristles of a soft toothbrush can irritate exposed dentin causing sensitivity and pain.
One of the simplest ways to minimize or prevent sensitivity is by teaching proper brushing techniques so that teeth are cleaned without causing either sensitivity or damage. Brushing too hard is a frequent culprit. Being overzealous can literally cause gum recession, leave dentin, and wear it away leaving it grooved. Another step to minimize sensitivity is to use a toothpaste containing fluoride. Fluoride increases the strength of tooth surfaces and thus makes teeth more resistant to attack by acids and sweets. If severe, we may need to apply a barrier to cover the sensitive areas. These barriers may range from concentrated fluoride varnishes to replacing lost tooth structure with filling materials.
