Tooth enamel erosion is a serious issue for many children that can result in permanent impairment of oral health. The problem isn’t just bacterial acid that causes tooth decay — it’s also the high acid content of sodas, energy and sports drinks widely popular among children and teenagers today.
Enamel is made of the strongest substance in the human body, which enables it to shield the inner layers of the teeth from disease and other environmental factors. Its chief nemesis, though, is acid: when enamel interacts with high concentrations of acid for a prolonged time, its mineral content will begin to soften and dissolve, a process known as de-mineralization. Saliva is the enamel’s main protection against acid with the ability to neutralize (or buffer) acid and restore some of the enamel’s mineral content, usually within thirty minutes to an hour after we eat.
The high acid content of many popular beverages, however, can overwhelm saliva’s buffering ability, especially if a person is sipping for an extended time on an acidic drink. This kind of exposure is different from acid produced by bacteria that causes tooth decay: bacterial acid tends to concentrate in specific areas of the teeth, while the constant wash from acidic beverages will have a more generalized eroding effect on teeth.
This level of enamel loss is irreversible, which can leave a tooth in peril of decay and ultimate loss — and increase long-term dental care and costs. The best strategy is to have your child stop or significantly curtail drinking highly acidic beverages. Rather than drink sports beverages for hydration, substitute water, nature’s hydrator. Milk can also be a viable beverage substitute.
If you do allow some acidic beverages, try to limit them to mealtimes and discourage extended sipping. Look for drinks with added calcium as this can reduce the beverage’s erosive potential. The goal is to reduce the amount and duration beverage acid is in contact with tooth enamel.
Making these changes will help greatly to protect your child’s tooth enamel, and give saliva a chance to do its job protecting it. Your efforts will also increase your child’s chances of better dental health in the future.

A few days before the Oscars, Vanity Fair magazine asked Academy Awards host Neil Patrick Harris to name his most treasured possession. Was it his Tony award statuette for best leading actor in a musical? His star on the Hollywood Walk of Fame? The stethoscope he wore while playing teenaged doctor Doogie Howser on TV? No, as it turns out, the 41-year-old actor’s most treasured possession is… his wisdom teeth. Yes, you read that correctly. “Oddly, I still have my four wisdom teeth,” Harris said. “I refuse to let them go or I’ll lose my wise parts.”
How odd is it for a 41-year-old to have wisdom teeth? Actually, not that odd at all. While it is true that wisdom teeth are often removed, there’s no one-size-fits-all approach to this. It all depends on whether they are causing problems now, or are likely to cause problems in the future.
The trouble wisdom teeth cause is related to the fact that they are the last molars to come in, and that molars are large in size. By the time wisdom teeth appear between the ages of 17 and 21, there often is not enough room for them in the jaw. Sometimes it’s because you may have inherited a jaw size that’s too small for your tooth size; and generally speaking, the size of the human jaw has evolved to become smaller over time.
If room is lacking, the adjacent molar (that came in earlier) can interfere with the path of eruption — causing the wisdom tooth to come in at an odd angle. The wisdom tooth can hit up against that other tooth, possibly causing pain or damaging the adjacent tooth. This is known as “impaction.” Sometimes the wisdom tooth breaks only partway through the gum tissue, leaving a space beneath the gum line that’s almost impossible to clean, causing infection. A serious oral infection can jeopardize the survival of teeth, and even spread to other parts of the body.
If a wisdom tooth is impacted, will you know it? Not necessarily. A tooth can be impacted without causing pain. But we can see the position of your wisdom teeth on a dental x-ray and help you make an informed decision as to whether they should stay or go. If removal is the best course of action, rest assured that this procedure is completely routine and that your comfort and safety is our highest priority. If there is no great risk to keeping them, as Neil Patrick Harris has done, we can simply continue to monitor their condition at your regular dental checkups. It will be particularly important to make sure you are reaching those teeth with your brush and floss, and that you keep to your schedule of regular professional cleanings at the dental office. All healthy teeth are indeed worth treasuring.

Crowns are a mainstay of cosmetic dentistry used to improve your smile’s appearance in a variety of situations. Not all crowns are alike, though — and the differences could affect your cost.
Crowns or caps are needed to cover remaining tooth structure which was previously damaged. Tooth decay and trauma are the major reasons for damage or loss of tooth structure that make crowns necessary. After preparing the remaining healthy tooth to fit into the new crown, we then make an impression mold of the tooth for a dental technician to use to create the new crown. It’s at this point where the road to your new smile can take different paths, both in construction and how much artistry goes in to your crown’s formation.
Porcelain crown construction falls into two general categories. The first category involves life-like porcelain fused to an inner core of metal. Because many older types of porcelain tend to be brittle and subject to breaking under pressure, metals are used to strengthen the crown. A fused crown can thus provide both durability and a life-like appearance.
In recent years, though, new dental materials have made the second category — all porcelain crowns — a viable option. Either lithium disilicate or zirconium oxide account for nearly two-thirds of crowns made today. Although research on their durability is relatively new, initial results have been encouraging, showing advanced all-ceramic crowns can tolerate forces comparable to porcelain fused to metal (PFM) crowns used in bridges.
On the downside, these newer materials may be more expensive than PFM crowns. Costs for manufacturing may also increase depending on how life-like the matching of color with other teeth you desire your crown to be. For example, individual teeth aren’t a uniform color — there are gradations of color that can vary from the tip of the tooth to the root. To capture these gradations in an individual crown requires a high level of artistry and time by the dental technician, which increases the final cost.
If you’re in need of a crown, it’s best to first make an appointment for a consultation to review your options, and to consider both your expectations and financial ability. Together we can determine what it will take to create a new look for your teeth that fits your expectations and your budget.
