WhatsInYourToothpaste

What do burnt eggshells, crushed bones, brick dust and ox-hoof ashes have in common? Are they things you discovered in your kid's pocket? Ingredients in a witches brew? Funky organic compost materials?

It may be hard to believe — but they're all substances that were once used to make toothpaste, from ancient Egyptian concoctions through 18th century British blends. But don't worry: You won't find any broken crockery or ashes inside a modern tube! Today's toothpastes are scientifically formulated to be effective in removing plaque, which helps prevent tooth decay and gum disease (not to mention bad breath.) So what makes them work so well?

One class of ingredients found in all toothpastes is abrasives — also called cleaning and polishing agents. These slightly grainy substances make the mechanical action of brushing more effective. But unlike crushed bones, or the harsh, gritty particles of yore, today's abrasives are designed to remove stains and bacterial films without damaging tooth structure.

Next come detergents, which account for the foam you see when you brush vigorously. Detergents (sometimes called “surfactants”) help to break up and wash away materials that would otherwise be difficult to dissolve. An ingredient called sodium lauryl sulfate, which is also found in many shampoos, is probably the most common detergent used in toothpastes.

Fluoride, first included in toothpaste in 1914, is another common ingredient. In fact, all toothpastes that carry the seal of the American Dental Association contain it, typically in the form of sodium fluoride, stannous fluoride or sodium monofluorophosphate. It has been proven to make tooth enamel stronger and more resistant to decay.

In addition to these primary components, toothpastes generally contain flavorings to make them more palatable, and binders and preservatives to hold them together and keep them from drying out. Special-purpose toothpastes — like those designed to whiten teeth, prevent tartar, or help reduce sensitivity — have added ingredients.

But regardless of what's in your toothpaste, there's one thing you should remember: It's not the paste (or the brush) that keeps your teeth and gums healthy — it's the hand that holds it! Brushing once or twice a day, using a soft brush with the proper technique (and your favorite toothpaste!) is probably the most important thing you can do at home to enhance your overall oral health.

UnderstandingToothSensitivity

Tooth sensitivity is an all too common problem among dental patients. If eating certain foods or simply touching a tooth causes you pain, you should know why this may be happening and what can be done about it.

Tooth sensitivity occurs in most cases because the portion of the tooth known as the dentin has been exposed. The dentin contains nerve fibers that inform and alert the brain about the current environment of the tooth (temperature or pressure changes). The enamel protects the tooth from environmental extremes.

Receding gums are the most common cause for dentin exposure — the enamel only protects the crown of the tooth and is not present on the root of the tooth. Acids in certain foods can then begin to erode the dentin around the roots and expose nerves. Sweet items (mainly sugar) and temperature shifts irritate the nerve endings, causing pain.

While receding gums (most commonly caused by brushing too hard and too often) may be the most common cause for sensitivity, it isn't the only one — tooth decay may also lead to it. Untreated, decay works its way into the tooth pulp and irritates the nerves. Treating the decay and filling the tooth may also cause sensitivity unless the dentist places a lining designed to minimize it temporarily while the area heals.

Alleviating pain from sensitivity begins with how you brush your teeth. Remember: the goal of brushing is to remove plaque, which does not require vigorous action. Brush gently with a soft-bristled brush and not too often. We might even recommend not brushing a very sensitive tooth for a few days to give the tooth a rest. You should also brush with a toothpaste containing fluoride, which will help strengthen the tooth surface against the effects of acids and sweets.

During an office visit, we can also apply a fluoride varnish or use certain filling materials that will serve as a barrier for the sensitive area. For cases where decay has irreversibly damaged the tooth pulp, a root canal may be the best treatment.

Tooth sensitivity isn't necessarily something you have to live with. There are treatments that can relieve or lessen the pain.
