10 Tooth-Cleaning Devices & Products of Yesteryear

Original image

Here at mental_floss, as the name suggests, we take our dental hygiene seriously. Accordingly, we felt it would be only fitting and proper to take a closer look at the products and devices folks have used throughout the centuries to fight plaque, tartar, oral fungi and other miscellaneous cavity creeps.

1. Miswak Cleaning Stick

4 out of 5 dentists recommend sugarless gum to patients who chew gum, you say? Big deal! The miswak was recommended by Mohammad himself. In existence for thousands of years and still used to this day, the miswak comes from the twigs of the Salvadora persica (a.k.a. the Arak or Peelu tree). The fibrous stems aren’t just ideal for removing detritus, either—they're also a natural source of fluoride. A 2003 study on miswak vs. toothbrush use concludes that (when users are given proper instruction), chewing sticks are "more effective than toothbrushing for reducing plaque and gingivitis."

2. Early Toothbrushes

Thanks to international trade, by the late 1700s Europeans were consuming greater quantities of sugar than ever before, and tooth decay was consequently on the upswing. The common tooth cleaning practice at the time—rubbing a rag with soot and salt on the teeth—wasn’t doing the trick, apparently. Toothbrushes existed but were considered exotic, so they weren’t widely available. In stepped businessman William Addis, who reckoned the personal brush he used might have mass appeal and rolled the dice on manufacturing them. It was a good gamble: his brushes were an instant smash. Before long it was unfashionable not to use one—and fancy, bone-handled models of the sort shown here began to appear in droves.

3. Bejewelled Toothpicks

Back in the 1800s, it wouldn’t have been unusual to see the cream of fashionable society whipping out these silver or gold plated picks after a fine supper and going full tilt at their incisors. The trend persisted through the 1950s, and it wasn't unusual to find these sterling picks monogrammed or branded with the family crest. Takeaway: don’t be fooled by those boxes of sticks that say “Fancy Toothpicks.”

4. Dental File

From the Middle Ages through the early 1800s, barbers often doubled as dental surgeons. Because—then as now—pearly whites were considered desirable, dental surgeons were often engaged not only to perform extractions, but to whiten teeth. Their technique? Filing holes between the patient’s teeth, then coating their choppers with corrosive nitric acid. And sure enough, this process whitened people’s teeth. Unfortunately it also dissolved the enamel and eventually led to decay and worse.

5. Tongue Scrapers

Tongue cleaning has been practiced since ancient times in India and Russia. And those folks knew what they were about, since decaying bacteria and fungi on the tongue are related to many common oral care and general health problems (not to mention halitosis). Ivory and silver scrapers are just a few of the models used by the hygienically scrupulous in the 1800s, but these days you can (and should) pick up a plastic one at the nearest pharmacy.

6. Early Dental Floss

Even though folks had been using strings and strands of all sorts to dig gunk from between their teeth for centuries, the official invention of floss is generally credited to New Orleans dentist Levi Spear Parmly, who introduced his silk version in 1815. 73 years later, Johnson & Johnson received the first patent for dental floss, and the time-honored tradition of dental hygienists scolding their patients for not flossing often enough was born.

7. Rubber Disk Toothbrush

Here’s a 1931 design that never caught on, despite its very scientific assertion that “the rubber itself produce[d] a polish when used with a dentrifice [i.e., toothpaste or tooth powder]”. Perhaps the problem lay in the shape, or maybe the rubber toothbrush was just too weird compared to the brushes we'd all grown accustomed to by the '30s. At any rate, this was a huge flop.

8. Long-Handled Tongue Brush

Described as having “an unusually long handle, curved to fit the mouth," this Depression-era brush allowed its user to “reach any part of the tongue which may need cleaning,” thus saving exhausted tongue-brushers from the laborious task of raising their arms a few more inches.

9. Hands-Free Motorized Toothbrush

Wowza! This motor-propelled toothbrush allowed its busy owner to multitask, taking care of his choppers by means of a “vibrating arm," and thus leaving him free to shave, trim his nails or think really hard about whether shaving while a vibrating arm is scrubbing at his teeth is really a good idea. The design appeared and disappeared in 1937.

10. Bourbon & Scotch Flavored Toothpaste

Invented in 1954 by Don Poynter—the same man who brought us crossword-puzzle toilet tissue, by the way—these novelty pastes contained real alcohol. Thanks to a nice spread in Life magazine, they became a huge (but short-lived) seller.

5 Tips for Becoming A Morning Person

You’ve probably heard the term circadian rhythm. Your circadian rhythm is an internal clock that influences your daily routine: when to eat, when to sleep, and when to wake up. Our biological clocks are, to some extent, controlled by genetics. This means that some people are natural morning people while others are night owls by design. However, researchers say the majority of us fall somewhere in the middle, which is good news if you want to train yourself to wake up earlier.

In addition to squeezing more hours out of the day, there are plenty of other good reasons to resist hitting the snooze button, including increased productivity. One survey found that more than half of Americans say they feel at their best between 5 a.m. and noon. These findings support research from biologist Christopher Randler, who determined that earlier risers are happier and more proactive about goals, too.

If you love the idea of waking up early to get more done, but you just can't seem to will yourself from out under the covers, here are five effective tips that might help you roll out of bed earlier.

1. EASE INTO THE HABIT.

If you’re a die-hard night owl, chances are you’re not going to switch to a morning lark overnight. Old habits are hard to break, but they’re less challenging if you approach them realistically.

“Wake up early in increments,” Kelsey Torgerson, a licensed clinical social worker at Compassionate Counseling in St. Louis suggests. “If you normally wake up at 9:00 a.m., set the alarm to 8:30 a.m. for a week, then 8:00 a.m., then 7:30 a.m.”

Waking up three hours earlier can feel like a complete lifestyle change, but taking it 30 minutes at a time will make it a lot easier to actually stick to the plan. Gradually, you’ll become a true morning person, just don’t try to force it to happen overnight.

2. EXERCISE IN THE MORNING.

Your body releases endorphins when you exercise, so jumping on the treadmill or taking a run around the block is a great way to start the day on a high note. Also, according to the National Sleep Foundation, exercising early in the morning can mean you get a better overall sleep at night:

“In fact, people who work out on a treadmill at 7:00 a.m. sleep longer, experience deeper sleep cycles, and spend 75 percent more time in the most reparative stages of slumber than those who exercise at later times that day.”

If you don’t have much time in the morning, an afternoon workout is your second best bet. The Sleep Foundation says aerobic afternoon workouts can help you fall asleep faster and wake up less often throughout the night. “This may be because exercise raises your body’s temperature for about four to five hours,” they report. After that, your body’s core temperature decreases, which encourages it to switch into sleep mode.

3. MAKE YOUR BEDROOM IDEAL FOR SLEEP.

Whether it’s a noisy street or a bright streetlight, your bedroom environment might be making it difficult for you to sleep throughout the night, which can make waking up early challenging, as you haven’t had enough rest. There are, however, a few changes you can make to optimize your room for a good night’s sleep.

“Keep your bedroom neat and tidy,” Dr. Nancy Irwin, a Los Angeles-based doctor of psychology on staff as an expert in sleep hygiene at Seasons Recovery Centers in Malibu, suggests. “Waking up to clutter and chaos only makes it more tempting to crawl back in bed.”

Depending on what needs to be improved, you might consider investing in some slumber-friendly items that can help you sleep through the night, including foam earplugs (make sure to use a vibrating alarm), black-out drapes, light-blocking window decals, and a cooling pillow

Another simple option? Ditch the obnoxious sound of a loud, buzzing alarm.

“One great way to adapt to rising earlier is to have an alarm that is a pleasing sound to you versus an annoying one,” Dr. Irwin says. “There are many choices now, whether on your smartphone or in a radio or a freestanding apparatus.”

4. TAKE THE TIME TO PROPERLY WIND DOWN.

Getting up early starts the night before, and there are a few things you should do before hitting the sack at night.

“Set an alarm to fall asleep,” Torgerson says. “Having a set bedtime helps you stay responsible to yourself, instead of letting yourself get caught up in a book or Netflix and avoid going to sleep.”

Torgerson adds that practicing yoga or meditation before bed can help relax your mind and body, too. This way, your mind isn’t bouncing from thought to thought in a flurry before you go to bed. If you find yourself feeling anxious before bed, it might help to write in a journal. This way, you can get these nagging thoughts out of your head and onto paper.

Focus on relaxing at night and stay away from not just exercise, but mentally stimulating activities, too. If watching the news gets your blood boiling, for example, you probably want to turn it off an hour or so before bedtime.

5. GET YOUR DAILY DOSE OF LIGHT.

Light has a immense effect on your circadian rhythm—whether it’s the blue light from your phone as you scroll through Instagram, or the bright sunlight of being outdoors on your lunch break. In a study published in the Journal of Clinical Sleep Medicine, scientists compared the sleep quality of 27 subjects who worked in windowless environments with 22 subjects who were exposed to significantly more natural light during the day.

“Workers in windowless environments reported poorer scores than their counterparts on two SF-36 dimensions—role limitation due to physical problems and vitality—as well as poorer overall sleep quality," the study concluded. "Compared to the group without windows, workers with windows at the workplace had more light exposure during the workweek, a trend toward more physical activity, and longer sleep duration as measured by actigraphy.”

Thus, exposing yourself to bright light during the day may actually help you sleep better at night, which will go a long way toward helping you wake up refreshed in the morning.

Conversely, too much blue light can actually disturb your sleep schedule at night. This means you probably want to limit your screen time as your bedtime looms closer.

Finally, once you do get into the habit of waking up earlier, stick to that schedule on the weekends as much as possible. The urge to sleep in is strong, but as Torgerson says, “you won't want your body and brain to reacclimate to sleeping in and snoozing.”

New Device Sanitizes Escalator Handrails While They're in Use

LG

If you have ever hesitated to touch a well-used escalator's handrails for fear of contracting some disease from the masses, LG Innotek has an answer for you. The company just released a handrail sterilizer that uses UV light to kill nearly every germ coating the rubber belts, according to The Verge.

As the railings move with the escalator, they pass through the UV light, which kills 99.99 percent of germs, according to tech developer LG Innotek. The sterilizer is placed just before escalator users hop on, ensuring the handrails are still relatively clean when you grab on at the bottom. The device is a little bigger than a regular hand sanitizer dispenser (around the size of a piece of paper) and starts automatically when the escalator begins moving. It runs on power generated by the movement of the escalator.

UV radiation is used to kill super-germs in hospitals (and one company wants to bring it to planes), but it's relatively easy to use on your phone, your toothbrush, or anywhere else in your house. You can already get handheld UV sterilizers online, as well as aquarium-specific ones. In April 2017, LG Innotek released a faucet that purifies water by UV-sterilizing it inside the aerator. However, the fact that escalator railings are constantly on the move makes them easier to clean automatically than subway railings, door handles, and other potentially germy public surfaces we touch every day.

Bear in mind that while nobody likes getting a cold, germs aren't always bad for you. Some types can even help protect you against developing asthma, as scientists found while researching the health differences between Amish children and their counterparts on more industrialized farms. Whether you touch the handrails or not, cities have their own unique microbiomes, and those ubiquitous bacteria are pretty much guaranteed to get on you whether you like it or not. On the bright side, if you are a germophobe, UV sterilization has been touted as a possible alternative to other antibacterial treatments that cause supergerms.
