Healthy teeth make you happy to share your smile with the world. But there’s more to your smile than its beauty! There’s a lot of hard work going on, too. 

Teeth Are Designed for Efficient Eating

Because humans are omnivores, we can eat both meat and plants. That’s why our teeth have different shapes—they’re meant to help us process different types of food. 

• Incisors, our front teeth, have sharpish edges to help cut through meats and other firm foods when we bite.
• Canines, the pointed teeth, help tear food into bite-size portions.
• Premolars are flat topped teeth with two cusps, raised points which help us grind food.
• Molars are the flat-topped teeth in the rear of the mouth. They have four cusps to grind and crush food into a paste-like consistency. 

So: Incisors and canines bite and tear food into smaller pieces, which molars and premolars then crush and grind into a paste. Bite, tear, crush, grind—why all this food aggression? Because that’s the key to healthy digestion. 

Successful digestion begins with chewing. Chewing:

• Starts the process of breaking food down into digestible particles.
• Increases saliva production. Saliva binds food particles so that we can swallow easily.
• Expands the surface area of food particles, which allows the digestive system to extract nutrients more efficiently. 

When biting causes you pain, it can be hard to chew food. Swallowing becomes difficult when food particles are too large, and digestion becomes uncomfortable.

Bite pain can occur when there’s a deep cavity or an injured tooth, but it can also be caused when the teeth and jaws don’t fit together the way that they should. This misalignment is called a malocclusion, or bad bite. And while a malocclusion often makes eating more difficult, it can have further damaging effects as well.

Teeth Are Designed to Be Good Partners

While eating is probably the first thing that comes to mind when we think about dental duties, our teeth also work in coordination with other parts of our bodies. A malocclusion can interfere with these normally smooth interactions, affecting:

• Tooth and Jaw Health

Biting, chewing, and clenching put hundreds of pounds of pressure on our teeth and jaws. A misaligned bite misapplies this pressure, which can lead to damaged and unevenly worn teeth, tooth grinding, headaches, jaw pain, and other problems. 

• Speech

Our teeth work with our tongues and lips to form many of the phonetic sounds which make up speech. Try saying the word “teeth,” and see how your tongue and teeth work together! Misaligned teeth and jaws can affect speech development in children and pronunciation in children and adults.

• Face Shape

Our teeth and jaws help give shape to our faces. Alignment problems can affect facial symmetry and self-confidence.

You Can Help Your Teeth Work Their Best

Daily brushing and flossing, eating a healthy diet, and regular visits to your dentist for exams and cleanings help your teeth perform their many daily duties. But if bite problems are causing troubles with eating, tooth or jaw pain, difficulty speaking, or self-consciousness, it’s time to team up with your orthodontist. 

And just like your everyday dental care, orthodontic treatment works best with your active participation. 

• Make sure your teeth are their cleanest with careful brushing and flossing. You may need to brush and floss more often while you’re in treatment.
• If you wear braces, eat a braces-friendly diet. 
• Wear aligners, bands, or appliances for the hours recommended each day.
• Keep up with your orthodontic visits to keep your treatment on schedule.

Talk to your orthodontist to learn more about how to help your teeth work their best for you—and be ready to share that beautiful, hard-working smile!

Everyone wants a naturally aligned and beautiful smile, and it is no secret that orthodontic braces from our office can help deliver one. However, there are greater benefits to wearing braces than just having straight teeth. You’ll gain many oral health benefits in addition to the cosmetic ones.

Tooth Decay and Gum Disease

Crooked or crowded teeth may overlap each other and create tight spaces in between. These can make it very difficult to brush and floss effectively, allowing bacteria and plaque to build up, and eventually leading to tooth decay and gum disease. With orthodontic treatment, your teeth will become properly aligned and spaced, which allows for more effective brushing.

Difficulties with Speech

Your teeth play an essential role in speech. When they are out of line or lean too far forward or backward, this can affect your speaking patterns, and possibly cause embarrassment and frustration. Braces can readjust the positioning of the teeth to allow for clearer, more professional speech.

Bone Erosion

Bone and gum tissues begin to erode when there are no teeth to support. This is also true for poorly aligned teeth that leave gaps and spaces or place too much pressure on the jawbone due to a bad bite. With braces, the bones and tissues are less likely to erode and can continue to support the teeth in their new alignment.

Digestion

Your teeth play an important role in digestion. Before food ever enters your stomach, it has been partially digested by the teeth. If teeth are severely out of line, however, they may not play their role in breaking down food as effectively as they should. With braces, your teeth will be straightened into optimal alignment for eating and chewing.

It seems like the ads are everywhere these days—repair your enamel and reverse tooth decay with a tube of toothpaste! Are these claims too good to be true? Let’s dive into the science of tooth decay—how decay develops and how (and if!) it can be reversed.

Teeth can stand up to the powerful pressures of biting and chewing because over 95% of our enamel is made up of minerals. Calcium and phosphate ions in our teeth bond to form a crystal structure called hydroxyapatite. Because of the strength of this crystalline design, tooth enamel is the hardest substance in our bodies, even stronger than our bones. 

But bones, like most other parts of our bodies, are living tissue, which means that they can create new cells to replace old or damaged cells. Tooth enamel can’t regenerate new cells to repair itself. This means that when a cavity has made a hole in the tooth, the enamel can’t grow back. And, while enamel structure is very strong, it’s also vulnerable to damage—specifically, damage from acids. 

Our teeth are exposed to acids throughout the day, whether they are acids created by plaque bacteria or the acidic foods and drinks we consume. Acids dissolve mineral bonds, stripping calcium and phosphate minerals from the enamel and leaving weak spots in the tooth surface. This process is called demineralization. Demineralization is the first stage of tooth decay.

The good news? Our bodies are designed with a built-in defense mechanism to prevent demineralization from causing lasting damage. All through the day, saliva helps wash away acids in the mouth and bathes our teeth with new calcium and phosphate ions. These ions bond with the calcium and phosphate in our enamel, restoring enamel strength. This protective repair process is called remineralization. 

Now for the bad news. In the tug of war between demineralization and remineralization, saliva can only do so much. If your diet is heavy with acids, if you don’t brush away acid-producing plaque bacteria regularly, if you eat a lot of the sugars and starches which feed plaque bacteria, the remineralizing effects of saliva can’t keep up with the demineralizing effects of acids.

The first visible sign of demineralization is often a white spot on the tooth where minerals have been stripped from enamel. Studies have shown that enamel-strengthening toothpaste can be effective in this very first stage of tooth decay. Toothpastes which advertise enamel repair generally contain one or more of these ingredients:

• Calcium Phosphate
• Hydroxyapatite
• Fluoride 

Toothpastes with calcium phosphate or hydroxyapatite contain calcium and phosphate minerals, the building blocks of tooth enamel. Studies have suggested that these minerals can replace the calcium and phosphate ions stripped from enamel. These toothpastes may or may not contain fluoride, which is something you should discuss with your dentist before deciding on a specific toothpaste.

Fluoride toothpastes remineralize enamel—and more! Fluoride ions are attracted to the tooth’s surface, and, when fluoride ions join with the calcium and phosphate ions there, they form fluorapatite. Fluorapatite crystals are larger, stronger, and more resistant to acids than hydroxyapatite crystals. And, once bonded with tooth enamel, fluoride attracts the calcium and phosphate ions in saliva to remineralize the teeth more quickly. 

Why consider enamel-repair toothpaste? 

Once enamel is gone, it’s gone for good. If excess demineralization isn’t treated, a weak spot on the tooth surface will continue to erode, growing bigger and deeper until it becomes a hole in the enamel. This is a cavity, and your dentist will need to treat and repair your tooth to prevent the cavity from growing and potentially exposing the tooth’s pulp to bacteria and infection. 

If you wear braces, you want to be especially careful about excess demineralization. Because it can be hard to brush and floss effectively with braces, white spots and discolored patches are a common concern for those with braces, especially on the enamel around brackets.  

Talk to Dr. Daniel Ma at our Vancouver, BC office about which toothpastes can help restore a healthy balance between the ongoing cycles of demineralization and remineralization when you have braces. While tooth-repair toothpaste can’t fix cavities, these products can often strengthen demineralized enamel and reverse this earliest stage of tooth decay.

If you’re brushing your teeth twice a day during your orthodontic treatment, Dr. Daniel Ma and our team think that’s wonderful! But, don’t forget that it’s also important for you to visit your general dentist every six months, or as recommended, in addition to brushing your teeth and flossing. (And visiting our office for regular adjustments, of course.)

Dental checkups are crucial for maintaining good oral health. Your general dentist can check for problems that might not be seen or felt, detect cavities and early signs of tooth decay, as well as catch and treat oral health problems early. During an oral exam, your dentist can also check the health of your mouth, teeth, gums, cheeks, and tongue. Checkups will also include a thorough teeth cleaning and polishing.

If you have not been to the dentist in the last six months, let us know during your next adjustment visit and we will provide a few great references in the Vancouver, BC area!
