Have you ever wondered if you grind your teeth at night? If you did, how would you know? Has one of your loved ones told you that they’ve heard you grinding your teeth?
If so, you’re not alone: teeth grinding, aka bruxism, is a fairly common phenomenon across the US. Depending on the individual, it can be related to more or less serious health concerns, but no matter which category you fall into it’s disconcerting to realize that this is all happening to you while you’re at rest and without your knowledge. Don’t worry though, there are things you can do! We want to go over the causes behind bruxism with you today, as well as ways you can help prevent it in your life.
What’s behind bruxism?
Up to now, the theory has been that tooth grinding is closely associated with stress or anxiety. This may be the case for some, but what about others? For example, babies have been observed grinding their teeth –or gums– in utero, which raised questions in the scientific community. Since this discovery, another possible cause behind bruxism emerged: is it possible that grinding is a survival response?
Recent research suggests that it is. The grinding that researchers observed during their experiments appeared to be the body’s natural survival response to bypass symptoms of sleep apnea.
Though many may not know it, our bodies require all of our muscles to be relaxed for the brain to achieve deep sleep. When relaxed, the tongue takes up almost double the amount of space, which can obstruct the airway and respiration. This results in more trouble for some people than others.
Researchers observed sleeping individuals with blocked airways suddenly start grinding their teeth, which – interestingly enough – reopened their airways and allowed them to breathe normally again. Among other potential tested solutions was a CPAP (continuous positive airway pressure) machine, which served to restore full airway functionality and allowed sleeping participants to stop grinding their teeth and breathe properly.
So is grinding good or bad?
In the sense that bruxism is a response that saves your life if you stop breathing, bruxism is good. But in the sense of dental longevity, it’s bad. Bruxism can lead to damage of your teeth and jaw, and can bring about tooth sensitivity and chronic jaw pain. Headaches and periodontal tissue damage can also be related to bruxism.
Aside from oral health, tooth grinding disrupts normal sleep patterns. Did you know that all the great benefits of a full night’s rest only exist for you if you’ve made it to the deep sleep stage? So if you’re grinding your teeth regularly at night, you may not receive sleep-related benefits like improved memory, fat burn, muscle build, and tighter skin.
Teeth grinding can also serve as a red flag for sleep apnea, a serious sleep disorder in which breathing repeatedly stops and starts. Untreated sleep apnea can increase your risk of high blood pressure, stroke, cancer, diabetes, depression, and obesity.
What can I do if I grind my teeth while sleeping?
Talk to us if you suspect you’re grinding your teeth at night. Some of the symptoms to look for include: wear on your teeth, flattened tooth surfaces, abfraction (which is a loss of tooth structure along the gum line that is not related to tooth decay), sore jaw muscles or TMJ pain, or a jaw that clicks.
While we don’t make a diagnosis about your quality of sleep, we can help you figure out if you are grinding your teeth by examining your mouth for these signs. Your medical doctor might then encourage you to get a sleep study to figure out whether your bruxism is related to sleep apnea or not.
If you suspect your grinding is stress-related, there are a number of things you can do to decrease your chances of tooth grinding at night. Starting an exercise regimen or attending stress counseling might help, but here are a few easily implemented tips to help you reduce your chance of bruxism:
- Limit caffeine and alcohol before bed.
- Try not to chew on objects that aren’t food – chewing gum included. Chewing on items like pens, pencils, and chewing gum stimulates tension in your jaw.
- Try to recognize when you are tensing or clenching your jaw throughout the day. When you notice, place the tip of your tongue between your teeth; this encourages your jaw muscles to relax.
- Grab a warm washcloth and hold it to your cheek (in front of your earlobe) as you fall asleep. The warmth helps relax your jaw muscles.

Did you know that throughout the course of human evolution, our mouths and dental structures have changed a great deal?
Understanding our teeth means we have to consider the specific function(s) of each type of tooth in its current state, as each plays a vital role in the digestion process. Let’s explore how some of our teeth currently function and examine how they have changed over time. Who knows – it might lead to some insight into your own dental situation! 🙂
Incisors
Your incisors are the central four teeth that are positioned at the front of your upper and lower jaws. Maybe you’ve noticed on your own time in front of the mirror that these teeth in particular are thin and flat, but you may not know that they are also sharper and stronger than most of the other teeth in your mouth!
Incisors have not always been present in the human evolutionary chain. In fact, they developed in a way that can be correlated with when humans began to consume the meat of other animals. The main purpose of these teeth is to tear away the meat or flesh from other animals and bring it into the mouth to initialize the digestive process.
Canines
Canines flank the incisors – one each on the left and right sides, in both the top and bottom rows of your teeth. While the incisors tear into meat, the canines clamp down on it – keeping the meat locked into the oral cavity. Feel yours now – pretty sharp right?
Over the course of time, the exact size & shape of canines have varied depending on the source of food humans and their predecessors consumed, mostly either plants, meat from other animals, or both.
Bicuspids
Sometimes also referred to as pre-molars, our bicuspids are the next teeth in the lineup, and they are short and flat with a bit of sharpness to them for one of two purposes: the actual processing and breaking down of foods, or to move food along to the back of the mouth.
It’s hypothesized that bicuspids might have been the select few teeth for some of our ancestors who were already eating meat. For these ancestors, a good amount of chewing would occur here as the food is passed on for further processing.
Molars
In the very back of your mouth are your molars, appearing on both left and right sides in the upper and lower jaw. Your molars are flat and wide, which makes them a prime location to grind up and further process your food. This is where most modern humans end up chewing their food and it’s the last step before food moves to the next stage of digestion.
The molars are permanent teeth from the moment they emerge in one’s mouth – they do not emerge as baby teeth – and they’re held in very tightly by the roots of their teeth. Molars are stronger teeth that served the purpose of breaking down food thoroughly. This was especially the case for plant life, as their cellular composition is stronger and harder to break down.
As most have found out, our third molars – aka wisdom teeth – no longer can fit in our mouths properly. Why? Modern humans chew less than our ancestors because our diet is much softer now than it was then. The more one chews, the more the growth of the jaw is stimulated. (Our predecessors must have been eating a lot of interesting stuff!) So though all three molars fit well in our jaws before, they no longer do. Isn’t that interesting?
When considering the historical functions of our teeth compared to how they function now, it’s clear that our diets have heavily influenced the development of our pearly whites. Modern human diets have changed dramatically when compared to our ancestors. It will be interesting to see how our teeth develop into the future.

As dentists, we spend lots of time educating our patients about the importance of taking care of their mouth, teeth, and gums. On the surface, we want to help you prevent bad breath, tooth decay, and gum disease—all with the goal of helping you protect your teeth as you grow older. In addition to our work, researchers are discovering new reasons to brush, floss, and visit your dentist regularly. They are learning that having a healthy mouth can ward off more serious medical conditions at any stage in your life. An unhealthy mouth may increase your risk of health problems such as preterm labor, poorly controlled diabetes, and even heart attack and stroke.
Take it from Ashley, RDH, one of FDA’s own dental hygienists: “The mouth is a window to the rest of the body,” Ashley explains. “Oftentimes we see changes arise in the mouth before they are evident elsewhere in the body. Maintaining optimal oral health is crucial to overall health. Since the mouth is connected to the body we recognize that chronic inflammation or presence of disease isn’t just localized to the oral cavity, but has the potential to be linked to underlying conditions.”
Just as Ashley explains, your mouth can play a crucial role in learning more about your overall health. In fact, saliva is a great tool that can help detect a variety of substances such as certain cancer markers, cortisol levels, and can even be used to monitor bone loss in those prone to osteoporosis. Saliva is also a main defense against disease-causing organisms as it contains antibodies that can attack both viral pathogens and bacteria. However, saliva can’t always get the job done completely. Over 500 different species of bacteria thrive in your mouth at any given time and constantly form dental plaque. If you don’t brush and floss regularly, this plaque builds up along your gum line, opening the door for additional bacteria to accumulate in the space between your gums and teeth. This build-up leads to gingivitis, and can potentially lead to periodontitis.
Our gums are vascular and full of blood, so infections such as gingivitis and periodontitis can happen quickly. Once that gum layer is disrupted due to brushing, flossing, or an invasive dental treatment, bacteria can enter in the bloodstream, travel to any area of the body and potentially cause inflammation. Inflammation in the heart causes hardened arteries, or atherosclerosis, making it harder for blood to flow to the heart, increasing one’s chance of heart attack and stroke. Oral bacteria can also enter your bloodstream and stick to the lining of diseased heart valves, causing infective endocarditis.
Another important connection between oral health and overall health is that the bacteria connected to periodontal disease, streptococcus sanguis, plays a role in strokes. This bacteria can quickly spread to the heart through the gums, potentially causing a stroke. There is research to suggest that people with gum infections are at an increased risk of stroke and researchers mention that the more severe the infection, the greater the risk of stroke appears to be.
While the American Heart Association says there is no definitive, direct evidence that heart disease can be prevented by working to prevent gum disease, that doesn’t mean that it can’t help. That’s one reason why regular dental check-ups are important at any age.When was the last time you visited us? Schedule an appointment to get your gums checked out today!

In recent years, there have been lots of conversations about plastics in our every day lives. Residents in South Portland, Portland, and Falmouth have voted to manage and reduce the amount of plastic distributed by introducing fees, or even banning some plastics altogether. Polyethylene is the most common plastic in the world, but it is a problem for the environment because it isn’t biodegradable and lasts forever. At best, it breaks down into smaller particles, but still exists.
Over the past few years, skincare and toothpaste brands have been adding small beads to their products, claiming they enhance the cleaning ability of the product when in reality, they are only for decorative purposes. While seemingly harmless, these beads are actually plastic—the same plastic found in your grocery bags, trash cans, and bottles. Since these plastics don’t break down, even in water, where do they go?
Around your teeth you have channels in your gums called a sulcus, the same place where gingivitis begins. A healthy sulcus is only about 3mm deep, but is a perfect place for these microbeads of plastic to get trapped. Since they are smaller than a millimeter, hundreds of pieces can get stuck in your sulcus each time you brush.
While there is little evidence that these microbeads directly cause gum problems, the sulcus is very vulnerable. Your dental hygienist spends most of their time cleaning this small space around every tooth in your mouth. And if your sulcus isn’t healthy, then your tooth, and potentially your whole mouth, isn’t healthy. So, we think it is better to be safe than sorry!
You can check the ingredients lists to see if microbeads are lurking in your toothpaste. Check for polyethylene, polypropylene, polyethylene terephthalate, or polymethyl methacrylate. Researchers have found the following products contain either microbeads or other microplastics. We encourage you to check your bathrooms to make sure these products aren’t hiding in there!
Toothpastes that Contain Microbeads:
- Crest Pro-Health
- Crest Pro-Health for Me
- Crest Sensitivity
- Crest Complete Multi Benefit
- Crest Clinical Sensitivity Relief
- Crest 3D White Luxe
- Crest 3D White
- CVS Brilliant White
Toothpastes that May Contain Other Microplastics:
- Colgate Max Clean-Smart Foam
- Colgate Max Clean
- Elmex Anti-Cavity with Fluoride
- Glo Science, Inc. Glo Whitening Antioxidant
- Jason Naturals Sea Fresh Antiplaque and Strengthening
- Jason Naturals Powersmile Anti-Cavity and Whitening
- Tom’s of Maine Clean & Gentle Fluoride
While caution is due, do be aware that since the initial news broke on microbeads, manufacturers have been phasing microbeads out of their formulations. But if you’d like to learn more about how to counteract the presence of microbeads in your mouth – and the environment – check out StoryofStuff.org and BeattheMicrobead.org.

You’ve probably heard about 3D printing, but did you know that this technology is applicable to dentistry? Though it seems to have emerged straight from the pages of your favorite cyberpunk novel, it seems that digitally created implants may be in the cards for future dentists and healthcare professionals.
3D printing has also come to be known as additive manufacturing, which means that digital 3D models are turned into solid objects by building up layers of a certain material (matching the parameters of the digital model) to create a real life object!
Though the technology was first introduced as the natural next step after 2D printing on paper, it has quickly evolved into a game-changing manufacturing technology. So far industries including but not limited to aerospace, defense, and art and design have adopted the technology for a variety of uses. Though it’s not definite when or to what degree 3D printing might be adopted by the dental industry, there is great potential for patients’ dental needs to be fulfilled quickly and locally using this technology.
Most dentists would agree: every person’s mouth is unique. This is the main reason why 3D printing could be massively successful in dentistry. Crowns, bridges, retainers, splints, dentures, and surgical guides and instruments, all require some level of custom work to match each patient’s mouth.
“I love the idea of 3D printing as there are many ways for it to be used in dentistry,” Dr. Brian Brunacini commented. “Whether it involves a metal framework for a partial denture or making a crown, the technology can only help. As dentistry goes digital, the impressions we take are so accurate that having a perfect fit is easily accomplished, which reduces costs and the amount of time required for each fitting.”
Digital x-rays as well as scans and models have already begun to “digitalize” dentistry work systems. These systems are becoming increasingly commonplace. In fact, you may have already encountered 3D printing in dentistry, though you might not realize it: Invisalign utilizes 3D modeling and printing technology in the creation of their products.
Despite initial barriers as 3D printing tried to gain a foothold in the industry, it seems that further technological advances are removing issues like high cost, software unreliability, and material limitations. With the introduction of desktop 3D printers, the cost of professional 3D printers has dropped substantially. Desktop and large-scale printers alike have been able to perform accurately in a clinical setting. In particular, the usability and relative low cost of desktop models have made the technology accessible for dental firms of every size.
As more 3D printers, software, and materials continue to be released, the industry continues to change. 3D printing is already possible with pure metals, metal alloys, thermoplastics and thermoplastic composites, ceramics, and edible food materials. Materials can also be formulated to take on different textures. As one example, gum tissue can be replicated with materials that have a rubbery texture. The most important factor in assessing materials is the quality of the final printed product.
Each year, more and more materials are released in accordance with FDA regulation. Soon, companies will release biocompatible materials that will be compatible with certain printers models. This development will further expand the potential of the technology, and would result in printers being able to create custom dental implants, like crowns or bridges, right there in the office.
Dr. Brunacini offered his perspective on the future of this technology. “There are still a lot of hurdles ahead for 3D printing in dentistry,” he stated. “Something to keep in mind along the way is that the art of dentistry is very important to as well, and that art could be lost with machines fabricating a crown.”
Whatever is in store for 3D printing and dentistry, you can rest assured that you’re able to rely on the care and craftsmanship of your trusted team at Falmouth Dental Arts. Interested in dental technology and how it has evolved over the years? Let’s talk more at your next appointment!
