When It Comes to Oral Health, We Can Learn Something from the Beavers

By Staff writer, Youth Health

🌱 ‘Leave it to beavers’ right? The Oral Surgery Team

When it comes to understanding tooth decay, a group of researchers is saying, “Leave it to beavers.”

Researchers from Northwestern University have discovered something remarkable about the oral health of beavers, the semi-aquatic rodents that are known for their building skills and strong set of teeth.

These furry creatures certainly don’t enjoy the same conveniences humans have as far as taking care of their oral health is concerned. But unlike us, they don’t develop tooth decay.

The answer, it turns out, is the presence of iron in the enamel.

The enamel is one of the tissues that make up the teeth of humans and many animals including beavers. They are also the most visible parts-see the whites in your teeth?-and are made to be resistant to acids. Acid build-up happens based on the food a person eats. When there’s too much acid, it “dissolves” the enamel, making the teeth more sensitive and at risk of developing cavities.

The main composition of enamel is hydroxylapatite, which looks like nanowires. Surrounding it are magnesium and iron, both amorphous minerals. When the enamel tries to protect the teeth from acid deterioration, it’s not the nanowires that respond but these minerals. As the researchers put it, we do share a similar enamel structure but not composition with the beavers and perhaps other animals, and the difference in composition may help determine the degree of acid resistance of enamels.

In their study, the researchers looked into enamel of three animals including rabbits and beavers and analyzed the enamel’s amorphous structure using tomography.

They then exposed the enamel to acid while taking before-and-after images, then noticed that the nanowires remained but the surrounding minerals dissolved. Subsequently the team analyzed how these minerals help in increasing the enamel’s resistance and hardness and discovered that the incisors of beavers are pigmented and rich in iron, making it a much better enamel than one that’s treated with fluoride.

With this knowledge, the research may be helpful in gaining a better understanding of oral health, especially how tooth decay develops.

The entire research is available in Frontiers in Psychology journal.

How Chewing Gum Can Help Your Oral Health

By Jason Tetro, Huffpost 

The question has plagued dental professionals for years. Is chewing gum good or bad for your teeth? The rubbery substance has been used for millennia dating back to the Ancient Egyptians and Mayans. Originally gum was used to keep the mouth busy during times or work, ennui or angst but in the latter part of the 19th Century, specially formulated sticks were developed to help keep teeth white and improve breath.

Jump a hundred years later and the benefits of chewing were put under scrutiny. During the 1970s and ’80s, a number of studies revealed the lack of any dental benefit. There was no significant plaque reduction unless combined with normal oral health procedures, such as brushing and flossing. In contrast, the addition of sugars and other acid-promoting ingredients made gum an enemy rather than a friend of oral health.

As formulations modified, research revealed some benefit with alternative ingredient lists. The use of sugarless gum was shown to help if only to dilute out the levels of sugar and low pH in the mouth. The addition of sugar-substitutes xylitol and sorbitolhelped to reduce the formation of caries. In the case of xylitol, a lower incidence of other secondary problems including ear infections was also seen.

 Though research provided some indication of the impact of gum on health, few investigated the effects of chewing on the most populous resident of the mouth, sinuses and respiratory tract: microbes. There was a good reason for this lack of study; until a few years ago, no one really knew the nature of the oral microbiome other than those species known to be associated with dental cavities. As a result, the first studies focused on whether gum could reduce the levels of pathogens without any specific perspective on the rest of the over 250 different types contained in the average human mouth.

But last week, an international team of researchers provided the first comprehensive look at the impact of gum on oral health. Their initial goal was to identify the dynamics of chewing gum on the microbes. Yet, the results provided them — and us — with a potential path to even greater oral health with the help of a few moments of chewing pleasure.

The methods were relatively simple. The group asked five volunteers to chew one of two different sugarless gums containing sorbitol and other non-cavity causing ingredients. At varying time points between 30 seconds and 10 minutes, the volunteers spit the well masticated ball into a sterile solution. Then the researchers used a variety of methods ranging from culture to genetic techniques to identify the bacteria in the gum. To make the results even more robust, they looked at pieces under the electron microscope to visualize how the bacteria adhered to the matrix.

When all the data had been analyzed, the group was treated to a surprise. While they expected to see bacteria in the gum — and they did to the tune of 100 million per piece — they were taken aback when they found the highest concentrations in gum spit out after the first few minutes. As the time went on, the concentration decreased in a linear fashion.

This reduction in extraction efficiency over time might have been due to a higher level of saliva in the mouth or the lack of stickiness, allowing the bacteria to return to the mouth. Either way, the data suggested the best amount of time to chew in terms of oral health was anywhere from 30 seconds to two minutes. Any time after that, a loss of 10 per cent of the population per minute would occur.

The group then looked at the nature of the microbes in the gum. Again, there was a surprise waiting for them in the data. When they looked at the origin of the bacteria, not all isolates were part of the tooth or the salivary microbiome. In the case of one gum, less than half of the bacteria could be traced. The results suggested the majority of bacteria were transient rather than colonized.

This result was particularly intriguing as the gum could potentially remove any pathogenic invaders who might be on the lookout for a home. The team suggested this radical removal might actually assist the maintenance of health. While the oral cavity has the ability to fight off infections through immune function, enzymes and antimicrobial peptides, physical removal via gum chewing might offer significant help in the process.

The last step of visualization involved what the researchers suggested was akin to looking for a needle in a haystack. Despite the over 100-million bacteria isolated from a stick of gum, the researchers had difficulties finding a bacterium using the electron microscope. When they did, it was alone, not in clumps, and took up only a small surface area.

This latter result suggests a large potential for increased bacterial removal. By incorporating ingredients to make the gum stickier to pathogens, a means of oral health improvement could be developed. This could be beneficial to help individuals who are particularly susceptible to infections as well as those who might be travelling. They can maintain their microbiome by getting rid of the newly introduced strains.

Overall, this particular study reinforces the beliefs of those over a century and a half ago who believed chewing gum could be good for health. Although the road has been bumpy and formulations have changed to reflect the necessities of a healthy lifestyle, the influence of gum on oral health appears to be positive. Whether the goal is fresher breath or removal of pathogens, it seems a few minutes of gum chewing might be an excellent way to keep a healthy mouth.

Turbocharge your teeth cleaning: Hi-tech ‘triple toothbrush’ can clean your mouth in just ten seconds

By Mark Prigg, Daily Mail

Now you definitely have time to brush! Check out this clip on how to clean your mouth in just 10 seconds with this brand new toothbrush technology
For those who simply don’t have time to brush their teeth in the morning, help is at hand. The Oral Surgery DC Team

A new Kickstarter campaign is raising funds for a $99 triple headed electric toothbrush. Its inventors claim it can clean an entire mouth in just ten seconds.

‘Wouldn’t it be simpler and easier to always be sure you are brushing the right way, and just spend a few seconds brushing rather than 2 minutes?’ the firm behind the GlareSmile says. It says the three brushes work together. The two outer brushes respectively brush the vestibular and lingual/palatal surfaces of each tooth, while the central brush cleans the occlusal surfaces.

The rotation movement from the bottom to the top guarantees plaque removal the same way you would do with your manual or electric toothbrush, but faster and with no risk of mistakes.’Our team is led by a dentist, who has been searching for a solution for the last 5 years, and after several tests and prototypes has invented GlareSmile, the first electric toothbrush which works 100% automatically on your teeth, guaranteeing the correct brushing technique in just 10 seconds.’ it claims.

GlareSmile also has an internal memory which keeps track of the usage statistics, which can also be synced with an app. ‘By connecting GlareSmile to your laptop you can download all the statistics and through an App on your smartphone, connect to your dentist and share them,’ the firm said. The brush also has a built in UV light to kill bacteria. When inside the removable cap, the 3 brushes rotate against plastic listels, automatically removing any kind of residual from the bristles.

‘In an industry which has not experienced great innovations over the last decades, our aim is to spread this breakthrough change to make everyone’s oral health simpler and better,’ the Italian firm says.

“Can Drinking Lemon Water Damage My Teeth?”

Screen Shot 2017-03-09 at 8.34.33 PM

By David Wolf, DavidWolf.com

🍋 Sadly, that refreshing water with citrus fruit in your office can do more harm than you think! Read below for tips on avoiding the acidity and still enjoying the benefits. The Oral Surgery DC Team

The health benefits of drinking lemon water are very well documented. In the past, we’ve even recommended you drink a large glass of it first thing in the morning.

By doing so, as reported by Food Matters, you unlock a whole range of benefits that include boosting the immune system, improved digestion and strengthening of the liver.

Not to mention the fact that it can quench your thirst like no other flavored drink out there, something much appreciated as the hot summer months creep up on us.

But there’s a downside we often forget to mention when it comes to drinking lemon water and it’s no slouch…

Lemon Water’s Effect On Your Teeth


All citrus fruits, due to their acids, can damage your teeth. This is especially true for lemons. They contain high amounts of citric acid that quickly wears away at the enamel of your teeth.

Enamel is hard to grow back and once it’s severely damaged, it can even be irreparable.

Signs of enamel erosion include:

  • Tooth Discoloration – Enamel gives teeth their white appearance. Once it wears away, the teeth may have a yellow tint because dentin, the substance that formes the inside of your teeth, is showing through.
  • Transparent Edges – If the edges of the teeth are transparent, this is a sure sign that they enamel is thin and not as strong as it should be.
  • Tooth Sensitivity – The dentin is exposed to the nerve of the tooth. Therefore, if the enamel is being eroded, the inside of the tooth is exposed to temperatures that make eating or drinking cold things uncomfortable.

How To Get Around These Risks

I mean, you don't really want to give this up, do you?

I mean, you don’t really want to give this up, do you?

Wait! Don’t give up on lemon water just yet. Despite the potential for harmful effects, there are things you can do to prevent damage. Here are a few:

  1. Try cold lemon water instead of warm lemon water. This will reduce the amount of available acid that can touch your teeth.
  2. Don’t brush your teeth immediately after drinking lemon water. This will wear away the enamel even more as the citric acid is still fresh on your teeth. Before you do brush, rinse your mouth with water.
  3. Drink lemon water carefully so that it does not touch your teeth or drink with a straw so that it bypasses your teeth.
  4. Try lemon essential oil instead. It has all the benefits, but the oil is made from the lemon peel not the fruit. This makes it healthier for your teeth! 1 -2 drops in a glass of water is perfect!

Can You Handle The Tooth? 10 Things You Didn’t Know About Teeth

Screen Shot 2017-03-09 at 8.13.20 PMBy Amanda Green, Mental Floss

The average adult has 28 to 32 teeth, depending on their “wise” set of third molars or lack thereof. But besides the importance of brushing and flossing, how well do you know your chompers? From LED braces to pearly whites in hard-to-reach places, we bring you the tooth, the whole tooth, and nothing but the tooth.


About one in every 2000 babies is born with natal teeth, so sometimes baby’s first dentist appointment is only a few days after birth. Natal teeth usually grow on the bottom gums and tend to have weak roots; they’re often removed to prevent problems with breastfeeding and accidental swallowing. Being born with teeth can be a symptom of certain medical conditions, and ancient physiognomy associated it with evil—but it’s usually harmless. Advice columnist twin sisters Ann Landers and Abigail Van Buren were both born with teeth. So were Napoleon and Julius Caesar.


Losing baby teeth is a rite of passage, not to mention a small source of income for most kids. By age 3, the average child has a full set of 20 temporary teeth. These little chiclets loosen and eventually fall out as the permanent teeth below start to erupt. Children typically start losing teeth around 5 or 6 and finish in their early teens. But if a person doesn’t have a replacement permanent tooth, that baby tooth will stay put.


Mo’ molars, mo’ problems? Depends who you ask. People with hyperdontia have extra, or super-numerary, teeth. Most of these teeth remain hidden below the gumline, but occasionally they’ll erupt and crowd other teeth. If extra teeth crash a mouth party, a dentist can remove them, or an orthodontist can make bank straightening all of them out. Very rarely, a person will lose a “permanent” set of teeth at an older age, only to have a no-for-real-now set grow back in. The rest of us have to get dentures.


What exactly is the Tooth Fairy supposed to do with the teeth she collects? If she’s crafty, she might want to look into selling human tooth art on Etsy. Yep, there’s apparently a small—and more than a little creepy—demand for artsy molars and incisors. Exhibit A: These double rings made of molars. Exhibit B: This quirky pendant that, dare we say, looks really cute. But these molar cuff links? Designer imposters. Even actress Scarlett Johansson made a golden necklace out of one of her extracted wisdom teeth and gave it to her ex-husband Ryan Reynolds. Do you think she got it back after they split?


No one wants to deal with an abnormal growth, but teratomas are especially icky. The germ cell tumors can contain several types of tissues and are usually found in the ovaries, testes, and near the tailbone. Some of them even contain teeth. And hair. And occasionally eyes, hands, and other limbs! Fortunately, many teratomas are benign and can be surgically removed. If you’ve got one, here’s hoping the Tooth Fairy sends you a get well card.


Ever hear the expression “I’d give my eye-teeth”? One woman literally gave her eye a tooth to restore her vision. In 2000, Sharon Thornton lost her vision to Stevens-Johnson syndrome, a condition that destroys the cells on the eye’s surface. Nine years later, the 60-year-old woman elected to try an unusual surgery. One of her canines was removed, so her cheek and dental tissue could be implanted in her left eye, replacing the damaged cornea. Within a day, the blind woman had regained 20/70 vision and the hope of improved sight in the future.


Back in ye olde days of orthodontia, the most creative thing the metal-mouthed could do with their braces was choose rubber band color. Today’s options include Invisalign or lingual braces hidden along the inside of your teeth. Or you can modernize traditional braces with glow-in-the-dark or LED technology. In the former option, fluorescent rubber bands or brackets glow when light-activated. (Orthodontists suggest shining a flashlight on the braces for a quick demonstration.) The Japanese clothing store Laforet Harajuku invented LED braces for a January 2011 ad campaign. Switched on by smiling wide, these multicolored flashing lights don’t actually straighten teeth. They will, however, make you the coolest kid at a rave.


Straight white teeth might seem universally appealing, but one country’s snaggletooth is another country’s sex appeal. (How do you think Austin Powers got so much action?) In Japan, crooked teeth called yaeba are so coveted that some women with perfect teeth get crooked veneers to enhance their smiles. They figure that crowded chompers make them look younger and more adorable, which makes sense. American parents could save lots of money if the trend catches on here…


A third set of molars helped our larger-jawed ancestors grind up roots, nuts, and leaves. But nowadays, 35% of people are born without wisdom teeth. Most of the rest of us are encouraged to get ours removed—our mouths are too small; our dentistry to pricey to screw up. When our bodies no longer need an organ or part, it becomes vestigial and eventually disappears. According to scientists, future generations will lack appendices, wisdom teeth, and maybe even little toes.

“What Happens After My Tooth Extraction?”

Screen Shot 2017-03-09 at 8.31.54 PM

→ Here’s everything you need to know from Dr. Nkungula to help prepare for dental care after your visit: 

Post – Operative Mouth Care

Care of the mouth following a surgical procedure is essential in the healing process.

Bleeding: Some bleeding and oozing is normal for several hours after your procedure.

  • Avoid spitting, use of a straw and smoking.
  • Bite down on gauze pack in mouth for 20-30 minutes and then discard or change if necessary.
  • If bleeding is more than slight, bite down firmly on a moistened tea bag for 30 minutes.

Discomfort: If prescription was given, use as directed.

  • Take prescription as soon as you get home and before local anesthesia (numbing) wears off.
  • Do not take pain medication on an empty stomach as it may cause nausea.
  • If no prescription was given, over-the-counter medications (e.g. Aspirin, Advil) can be taken.

Swelling: Some degree of swelling is normal and can be minimized with the use of cold and hot gel pack – the table below is a guide.

WHEN USED? Day 1-2 Day 3 onwards
HOW OFTEN? 2-3 times daily 2-3 times daily as needed
WHY? Control and manage swelling Bone and gum healing and repair

Diet: A soft or liquid diet is recommended for the first few days following surgery.

  • Until local anesthesia (numbness) wears off, be careful chewing to prevent biting the numb area.

Care of mouth: Do not rinse your mouth vigorously for the first 24 hours after surgery as vigorous rinsing interferes with clot formation and slows healing

  • After 24 hours,begin gentle warm salt water rinses for one week at extraction site and resume gentle brushing of remaining teeth.
  • Avoid use of alcohol, smoking or carbonated drinks for 1-2 days after surgery.

Note: Antibiotics may decrease the effectiveness of birth control medications.  Additional methods of birth control should be used while on antibiotics.
