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.

For adults with a reasonably well fitting bite, but mild to moderate crowding or spaces between your teeth, clear orthodontic aligners can be an ideal solution for straightening your teeth. This is why we offer this treatment option to our patients experiencing these issues. However, for those of you who are unfamiliar with what they are or how they work, this will give you a brief understanding.

Clear orthodontic aligners consist of a series of clear “trays” that fit snuggly over all teeth to slowly shift them into alignment. Patients are typically required to wear them 20 hours per day for about 2 weeks before progressing to the next tray. With each new tray, you are one step closer to achieving your goal of perfectly aligned teeth. The entire process usually lasts 6-18 months depending on how much movement is required to achieve the goals.

Each aligner is individually made from very precise molds of the patient's teeth to ensure proper fit. And we map out the entire alignment process using computer generation from each patient's initial molds so that we can identify the number of trays required. But best of all, clear orthodontic aligners are perfectly smooth with no rough edges like traditional braces, and you can remove them for eating, brushing, and flossing teeth as well as for brief social events.

We have noticed that there are two types of patients when it comes to enhancing a person's smile. One type, which we'll call the “Perfect Minded” patient, expects teeth that are completely regular in their arrangement and of maximum whiteness and brightness, often beyond the range of traditional guides for tooth color. They are looking for a perfect “Hollywood” smile. The other, the “Natural Minded” patient, is looking for a more natural look. This person expects a general sense of regularity and alignment of teeth with definite brightness, but not so much that the teeth are noticeable before and above other facial features. Which type are you?

The “Perfect Minded” Patient
While you expect maximum regularity and alignment of teeth along with maximum whiteness and brightness, the “perfect minded” patient requires a smile completely symmetrical (balanced from one side to the other). If we drew a vertical line down the center of your face (midline), it would fall directly between your front teeth and your smile would look just the same on each side of the line. You also expect your smile to be horizontally symmetric, so that it matches the curvature of your lower lip and the gum lines match from side to side.

The “Natural Minded” Patient
You are looking for a more subtle, natural look produced by including some minor irregularities in your look. Like the “Perfect Minded” individual, you still expect your teeth to be generally regular and well aligned but you also want to have some minor asymmetries (not matching) as you move farther back along your jaw to make your teeth look real. Your preference in tooth color is not a super shade of white, but for a tooth color that looks very natural for your facial skin and hair color.

There is no right or wrong here. What is important is to be sure to communicate your expectations to us before embarking on a program of smile redesign.

Hearing the news that you need a root canal often causes anxiety for most people given all the bad press this procedure has received (e.g., “I'd rather have a root canal than...”). However, the truth is that root canal treatment relieves pain; it doesn't cause it. And it is typically highly successful. The real pain occurs for most people when decay is left untreated or the nerve in a tooth under a very large filling becomes infected and dies.

For these reasons, we have put together the following list of questions you should consider asking prior to having a root canal or endodontic (“endo” – inside: “dontic” – tooth) treatment.

• Am I a good candidate for root canal treatment?
• Does it hurt to have a root canal?
• What can I expect if I do not have a root canal treatment?
• Are there any other treatment options for me given my situation? If so, what are they?
• Do you do root canal treatment or should I see a specialist?
• How long will the entire process take from my first appointment until my root canal treatment has healed?
• Will the pain I am in immediately subside after a root canal or will it take some time?
• Will I need or receive any type of sedation while having the treatment?
• Are there any risks associated with root canal treatment? If so, what are they?
• How long can I expect my natural tooth to last after root canal treatment?
• What could happen to cause a root canal to require a second treatment?
• How much will my root canal cost?
• Will my insurance cover all or a portion of the cost?
• Will the tooth be as strong after root canal treatment, or will it need a crown?
• Will there be any special maintenance required on an ongoing basis after I have a root canal?
