Tooth plaque provides unique insights into our prehistoric ancestors' diet
An international team of researchers has found new evidence that our prehistoric ancestors had a detailed understanding of plants long before the development of agriculture. By extracting chemical compounds and microfossils from dental calculus (calcified dental plaque) from ancient teeth, the researchers were able to provide an entirely new perspective on our ancestors' diets. Their research suggests that purple nut sedge (Cyperus rotundus) -- today regarded as a nuisance weed -- formed an important part of the prehistoric diet.
Coconut Oil To Help Prevent Tooth Decay
This new discovery is expected to lead to a new approach to dental hygiene products. People who are sensitive to chemical additives may be able to use the treated coconut oil more readily. Current microbial infections are getting more anitbiotic-resistant, which means that scientists will need to find new ways to combat them.

Fighting for oral dominance: Good fungi keep bad ones in check in healthy mouths
Human mouths contain a balanced mix of microbes which, when disrupted, can lead to oral diseases. A new study compares the bacteria and fungi present in the mouths of healthy individuals with those from patients infected with HIV and illustrates why oral candidiasis (aka 'thrush') is a common complication of HIV infection.

Craze Lines: Hairline Cracks In Your Front Teeth
Catherine recently left a comment asking about the discolored lines that she has running vertically in her front teeth. She was curious about what kinds of solutions there are to deal with this cosmetic problem.
Before I talk about the solutions to these lines that can occur in our teeth, I'll give an overview of what they are, why they happen, and how to get rid of them.
Craze Lines: Vertical Lines in Our Teeth
These vertical lines in her front teeth are actually known as craze lines. Over years of use, our teeth tend to develop tiny cracks in the hard outer layer known as enamel. These cracks normally don't cause any pain, but can easily stain, causing embarrassing discolored lines on your front teeth.
What Causes Craze Lines?
Craze lines can be caused by stress placed on a tooth. This can happen over the course of a lifetime of chewing or by any other process that causes a lot of stress on our teeth.
Some common causes of craze lines are biting your nails, grinding your teeth (many people do it in their sleep without realizing it), using your teeth as tools, trauma to your teeth, or simply routine use of your teeth.
In Dr. Cohen's textbook about root canals, he states, "Craze lines are merely cracks in the enamel that do not extend into the dentin and either occur naturally or develop after trauma."
This case report describes a situation where craze lines were caused by biting on hard objects such as the top ring of an aluminum soda pop can. Speaking of metal rings, wearing tongue rings can cause craze lines in your teeth.
Interestingly, some research points to temperature changes as a possible cause of craze lines. That's a great incentive to not chew ice cubes (especially after drinking hot coffee!)
One other cause of craze lines that should be discussed is going to the dentist. This research article states that he process of drilling away a cavity and filling a tooth can cause craze lines. That's certainly not a reason to avoid the dentist, though, since craze lines are harmless whereas untreated cavities can lead to significant complications.
Do Craze Lines Mean Your Teeth are Cracked?
Although craze lines are very tiny cracks in the outermost layer of your tooth, you don't need to worry about your tooth cracking in half.
One good way to think about craze lines is to take a look at the above photo of this porcelain doll. The cracks in the porcelain occurred after years of use. Although they are cosmetically displeasing, the cracks don't mean that the doll's head is about to crack open!
If you suffer from craze lines, you'll be pleased to know that the way that our teeth forms makes the enamel highly resistant to cracking.
A recent study looked at the crack resistance of the enamel in our teeth compared to a synthetic enamel. The study concluded, "While enamel is the most highly mineralized tissue of the human body, the microstructural arrangement of the prisms promotes exceptional resistance to crack growth."
If that isn't enough, this study says that "The microstructure of enamel is functionally optimized to guide cracks from the more brittle outer enamel inwards where they experience higher growth resistance and are prevented from causing fracture and chipping."
This study found that enamel is about three times as tough as the naturally-occurring crystals of hydroxyapatite (the crystal that our tooth is made from.)

How to Get Rid of Craze Lines
So, what should you do if you have craze lines and you hate how they look? There are a few alternatives.
The least invasive option is to try teeth whitening. Many craze lines show up because tiny amounts of debri get into the crack and stain the crack, making it visible. Teeth whitening can bleach away the stain and make the craze lines very hard to detect.
There are other options that involve actual dental work. Before trying these options, it's good to keep in mind that craze lines can be caused by dental work, and that no dental work is better than your natural teeth.
These options include having an aesthetic tooth-colored filling material placed over the crack or having a veneer. To do the filling, your dentist will simply smooth down the tooth in the affected area and add some filling material that is the same color as your natural tooth. To do a veneer, your dentist will smooth down the whole face of the tooth and place a thin piece of porcelain over the tooth (kind of like a fake fingernail.)
Conclusion
With these alternatives in mind, it's worth noting that most dentists agree that there's no need to treat craze lines since they rarely lead to further breakdown of the tooth. Some studies (like this one) do argue that the small lines may serve as a future site of a cavity, but if you're going in for your regular check-ups, your dentist can usually detect potential problems.

Osteoporosis drugs appear to impede cell membrane repair
A class of drugs widely used to treat osteoporosis appears to impede a cell's ability to repair a protective outer membrane that helps determine what enters and exits, researchers report. The inability to quickly repair a membrane is lethal to a cell and may help explain the rare and serious side effect of jawbone destruction that can occur following dental work in patients taking these drugs, the researchers note.

Gum disease bacteria selectively disarm immune system, study finds
Bacteria responsible for many cases of periodontitis cause an imbalance in the microbial community in the gums, with a sophisticated, two-prong manipulation of the human immune system, research shows. Not only does the team's discovery open up new targets for periodontitis treatment, it also suggests a bacterial strategy that could be at play in other diseases involving dysbiosis.

Byproducts of bacteria-causing gum disease incite oral cancer growth, study shows
Researchers have discovered how byproducts in the form of small fatty acids from two bacteria prevalent in gum disease incite the growth of deadly Kaposi's sarcoma-related lesions and tumors in the mouth. High levels of these bacteria are found in the saliva of people with periodontal disease, and at lower levels in those with good oral health -- further evidence of the link between oral and overall physical health. The discovery could lead to early saliva testing for the bacteria, which, if found, could be treated and monitored for signs of cancer and before it develops into a malignancy, the researchers say.

Gum disease bacteria may cause heart disease
The same bacteria that cause gum disease also promotes heart disease -- a discovery that could change the way heart disease is diagnosed and treated. Heart disease is the leading cause of death in the North America. Gum disease affects 46 percent of the U.S. population and is caused by bacteria that grow on the teeth under the gums. Although doctors know that patients with gum disease are at higher risk for heart disease, gum disease isn't viewed as a traditional risk factor for heart disease.

No One Is Safe From Morning Breath!
 | Morning breath is just a fancy way of saying bad breath. Don’t worry, it’s common – everyone gets it and there is nothing to be ashamed of. Although you cannot stop it from happening, there may be some ways to reduce the odor. In order to minimize bad breath, you have to first understand why it happens. When your are sleeping, the normal flow of saliva decreases. This causes your mouth to dry out, providing the perfect atmosphere for odor-producing bacteria to multiply. Unfortunately, this means that no one is safe from morning breath. Here are a few tips to help fight bad breath:
As simple as these steps may be, many people ignore them resulting in bad breath. The most effective way to combat morning breath is with proper oral hygiene. Remember, morning breath is normal. There is no reason to be embarrassed – everyone gets it! |

Tooth loss linked to depression, anxiety
Tooth loss from caries and periodontal disease is an outcome from complex, chronic conditions. Several biopsychosocial factors are involved, including accessing care. Individuals reporting dental anxiety may avoid dental care; and individuals with depression may be negligent in self-care. In this study, researchers examined a potential association of tooth loss with depression and anxiety.

'Microbial Pompeii:' 1,000-year-old plaque preserves bacteria, microscopic particles of food on skeleton teeth
A ‘microbial Pompeii’ has been discovered, preserved on the teeth of skeletons around 1,000 years old. The research team discovered that the ancient human oral cavity carries numerous opportunistic pathogens and that periodontal disease is caused by the same bacteria today as in the past, despite major changes in human diet and hygiene. “The study of ancient microbiomes helps us understand the evolutionary history of human health and disease," says a senior author of the study. “It informs modern medicine.”

Functional Website Design: More Than Just a Pretty Face
Website design and dentistry have more in common than you might think. The same principle applies to designing an attractive, effective dental website. A pleasing color scheme and high-quality images may site visitors’ attention, but functionality keeps them on your site and ultimately drives them to make contact. For now, let’s focus on principles of functional dental web design; we’ll look at aesthetics in a later post.
WHO will visit our website?
Patients, obviously, but let’s break it down further. Does your practice generally cater to a few clearly defined demographics? If dental implants are your signature service, your audience will most likely be older adults. A pediatric dentist would design a website that speaks to parents, especially mothers. Are they tech-savvy?
WHY are they visiting our website?
Remember the days when the search for a dentist began with a long list of names and numbers in a phone book? Information was limited at best with no indication of a dentist’s specialty, exact distance, patient satisfaction, or accepted insurance providers. It wasn’t that this information wasn’t important then, rather a matter of space constraints. Ideally, your website should present this information in a logical, easily navigated format. Drop-down menus and toolbars come to mind.
HOW do they visit our website?
Ten years ago, it was as simple as designing for a laptop or desktop screen. Today, your patients access the Web on smartphones and tablets with varying screen sizes and loading times. Responsive web design–design that accommodates a variety of browsers and devices–is critical. If your site isn’t optimized for different viewing experiences, you’ve alienated a sizable chunk of your target audience.

Copywriter Magic: Turning Your Practice Into Words
We Will Interview You
Not only will we ask you standard interview questions, but we will likely also ask you some not-so-run-of-the-mill questions, like what your favorite movie is, or what you like to do in your spare time. Part of the magic that goes into turning you into a relatable person online, while promoting your business, is ensuring we capture your personality and goals. Through years of experience, we have become familiar with the subtle nuances of a website that capture a patient’s attention. Our copywriters make detecting those major and minor details that truly resonate with a dental patient their number one priority. They also create your web pages around your practice’s goals. Are you focused on driving home your patient-centered approach to dentistry? Do you primarily offer cosmetic services? We’ve got you covered.
Copywriters Love Words
Did I mention how much copywriters love words? First, copywriters make sure content is SEO’d, accessible and easy to read. Choosing the right words is as significant as ensuring the copy reads smoothly. In addition, we recognize that while our writers have a solid knowledge of clinical dentistry, your patients probably don’t. Furthermore, they probably don’t want to. Our writers are masters in turning scientific information – and often-unpleasant information – into content your patients will understand, connect with, and that will not cause them to run from the screen. Copywriters will not write, for example, “decrease discomfort” but “improve comfort.” They will focus on the positive aspects of dentistry to set readers’ minds at ease. MDPM writers create clean, factual web pages, while drawing on both the emotions and logic of your patients, so they feel compelled enough to pick up the phone and make an appointment.
Revisions
Did something change suddenly, such as your address? Did you read through your website only to find something didn’t translate exactly as you had hoped? With lightening speed (without sacrificing accuracy and thoughtfulness) our copywriters will make revisions according to your needs. Our goal is twofold: to ensure we create a website that assists you in attracting and retaining new clients, and to ensure that you feel your website truly reflects your dental practice.

Eruption Cyst: Photos of a Purple Bump on the Gums
A little over a year ago, I wrote an article discussing eruption cysts. Those are the bluish-purple bumps that can form on the gums right before a tooth pushes its way into the mouth.
Upon first glance, many parents are understandably concerned that their child has a serious problem in their mouth. The photo I used in the original article isn't very clear, and I thought it would be good to post a couple more photos that were recently shared with me.
Photos of Eruption Cysts
The photo below shows two eruption cysts over the permanent upper front teeth. The teeth are still white, the purple color is due to bruising that has occurred between the gums and the permanent tooth. Usually, no treatment is necessary and the teeth will come through within a couple of weeks.
The next photo shows an eruption cyst where the upper left six-year molar is preparing to come into the mouth. Many parents may not even notice eruption cysts when they occur this far back in the mouth.
Fact: Since many eruption cysts occur on the back teeth and only last a few weeks, they often go undetected. Because of this, nobody really knows how common eruption cysts really are. Most estimates say that they occur in under 1% of all children.
To Treat or Not to Treat
Normally, eruption cysts don't need any treatment. The tooth will usually poke through the eruption cyst and come into the mouth on its own within a couple of weeks. If the eruption cyst is causing lots of pain, or if it is causing concerns due to its appearance (as in the first photo), it can be cut open to expose the tooth.
You can click the following link to check out a picture of a tooth after its eruption cyst has been opened.
More Pictures of Eruption Cysts
You can find more photos of eruption cysts in this article that appeared in the Indian Journal of Dental Research.
If you have any questions or concerns on eruption cysts, feel free to leave a comment in the comments section below. Thanks for reading!
