KeepingFluoridetoJusttheRightAmountProtectsYourFamilysSmiles

Since the 1950s fluoride has played an important role in the fight against tooth decay as an additive to hygiene products and many public water supplies. But although a proven cavity fighter, some have questioned its safety over the years.

To date, though, the only substantiated health risk from fluoride use is a condition known as enamel fluorosis, which occurs when too much fluoride is ingested during early tooth development as the mineral embeds in the tooth structure. Fluorosis can cause changes in the enamel’s appearance, ranging from barely noticeable white streaking to darker visible staining and a pitted texture.

Fluorosis is primarily a cosmetic problem and not a serious health issue. The staining on otherwise sound teeth, however, is permanent and more severe cases may require extensive bleaching treatment to improve appearance. The best strategy is to prevent fluorosis by monitoring and limiting your child’s fluoride intake, until about age 9.

Tooth decay is a more serious condition than fluorosis so we’re not advocating you eliminate fluoride but that you keep your family’s intake within safe levels. The first step is to determine just how much that intake is now, particularly if you drink fluoridated water. If you have public water, you may be able to find its fluoridation level online at apps.nccd.cdc.gov or call the utility directly.

You should also be careful about the amount of toothpaste your child uses to brush their teeth. Children under two need only a trace (a “smear”) on the brush, and children between the ages of 2 and 6 a pea-sized amount. And, they should brush no more than twice a day.

Another possible concern is infant formula, especially mixable powder. While the formula itself doesn’t contain fluoride, water mixed with it may. If you live in an area with increased fluorosis risk, consider breast-feeding (breast milk has little fluoride), using ready-to-feed formula, or mixing powdered formula with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”

We’ll be glad to help assess your family’s current fluoride intake and advise you on making adjustments to bring it into normal ranges. Taking in the right amount of fluoride assures you and your children receive the most benefit and protection from it, while avoiding future smile problems.

TRUEORFALSETheGreatToothpasteTest

You use toothpaste every day — don't you? But how much do you really know about what's inside the tube: namely, the white, sticky stuff that keeps your teeth clean and your breath fresh? Take this True/False quiz and find out!

True of false: Powdered charcoal, brick dust and crushed bones were once ingredients in toothpaste. TRUE

Many years ago, these gritty abrasive materials were used to make toothpaste. Today, abrasives are still used — but they're much gentler. Compounds like hydrated silica or alumina, calcium carbonate, and dicalcium phosphate have proven effective at cleaning and polishing tooth surfaces without damaging the enamel.

True of false: Fluoride was first introduced into toothpaste in 1955. FALSE

Arguably toothpaste's most important ingredient, fluoride was used as early as 1914. But its mass-marketing debut came with the Crest brand in the mid-1950s. Today, no toothpaste without fluoride can receive the American Dental Association's Seal of Approval. That's because it has been shown to strengthen tooth enamel and help prevent tooth decay.

True of false: Detergent is a common ingredient of toothpaste. TRUE

But it isn't the same kind you do laundry with. Detergents — also called surfactants, because they act on the surfaces of liquids — help to loosen and break down deposits on your teeth, which can then be rinsed away. Like other health and beauty products, many toothpastes use a gentle detergent, derived from coconut or palm kernel oil, called sodium lauryl sulfate.

True of false: Whitening toothpastes work, to some degree, on all stains. FALSE

Whether the whitening agents in toothpaste will work for you depends on why your teeth don't look white in the first place. The abrasives and enzymes in these toothpastes can help remove “extrinsic” stains: those on the surface of your teeth. But for “intrinsic” stains — that is, internal discoloration — they probably won't help. In that case, you may need to get professional bleaching treatments.

True of false: Toothpastes made for sensitive teeth have substances that block pain transmission. TRUE

Potassium nitrate and strontium chloride can block the sensation of pain that may occur when dentin — the material that makes up most of the inside of teeth, and is normally covered by enamel — becomes exposed. Fluoride, too, helps reduce sensitivity. But the benefits of reduced tooth sensitivity may take a few weeks to really be felt.
