The market for sugar alternatives has grown exponentially since saccharin was accidentally discovered in 1878. Today, saccharin has been joined by other FDA-approved zero-calorie artificial sweeteners, including aspartame (“Equal®” or “NutraSweet®”), sucralose (“Splenda®”) and rebaudioside A, derived from the stevia plant. You can also choose low-calorie alcohol sugars like erythritol or xylitol.

With rare exceptions, all these choices are widely considered safe substitutes for table sugar, high fructose corn syrup or other versions of this plentiful carbohydrate. Finding substitutes for sugar is a worthy health goal: besides its role in obesity, sugar is considered a contributing factor in cardiovascular disease and diabetes.

It's also a prime food for oral bacteria that cause dental disease. As bacteria consume sugar they produce acid as a byproduct. Acid softens and dissolves the mineral content in enamel, leading to erosion and the formation of cavities. While saliva normally neutralizes acid after we eat, constant snacking and higher quantities of sugar in our food make it difficult for it to control or neutralize acid in the oral environment.

Because most of us are hard-wired with a “sweet tooth,” it's difficult for many to cut back on sugar. Artificial sweeteners help reduce the amount of sugar in the diet with obvious benefits for general health. It can also make a big difference in your dental health by helping you prevent tooth decay.

One alcohol sugar may even go a step further. In addition to reducing the presence of sugar in the mouth, xylitol (found in chewing gums, candy and breath mints) also seems to reduce bacterial growth by interfering with their ability to ferment the sugar.

If you're considering using an artificial sweetener, get to know them first: some like aspartame aren't suitable for baked goods or cooking, while saccharine or sucralose are. People with a rare genetic condition called phenylketonuria also can't properly process aspartame in the body.

Be sure you also talk to us about artificial sweeteners' impact on oral health, especially the benefits of xylitol for dental care. Used in a wise and informed way, these sugar alternatives can improve both your oral and general health.

EdenSherandtheLostRetainer

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!

If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.

If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?

As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.

And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!
