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!

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. Neil Oliveira and Dr. Derek Wolkowicz at our New Bedford or Mattapoisett, MA 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.

Orthognathic surgery is surgery to correct a wide variety of abnormalities of our patients' jaw and teeth. The surgery is often done in conjunction with orthodontic treatment. While the patient’s appearance may be significantly improved as a result, the primary purpose of the surgery is to correct functional problems including but not limited to:

• Unbalanced facial appearance
• Protruding jaw
• Open bite (upper and lower teeth don’t overlap properly
• Excessive wearing down of the teeth
• Difficulty with chewing or biting
• Chronic mouth breathing
• Sleeping problems such as sleep apnea
• TMJ pain (jaw joint pain)
• Restoring facial injuries

Knowing when to start the orthodontic treatment in preparation for orthognathic surgery can also be tricky if our team at Orthodontic Specialists of Southeastern Massachusetts is treating a teenager. It is important to know when to get started. If orthodontic treatment is initiated too soon and the teenager is still growing, the patient will either need to hold in braces until his or her growth is complete and they are ready for surgery or the braces will have to be removed and then placed again when growth is complete. Neither of these options is attractive since it requires longer time in treatment, which is something all our patients want to avoid. Our team at Orthodontic Specialists of Southeastern Massachusetts strives to get all patients finished with treatment as quickly as possible because it is healthier for the teeth and gums and gives them a beautiful smile to enjoy for a lifetime.

If you are considering orthognathic surgery or you have been told that you need jaw surgery, give us a call to schedule your initial consultation today. Dr. Neil Oliveira and Dr. Derek Wolkowicz and our team at Orthodontic Specialists of Southeastern Massachusetts will explain our treatment plan in a way you will understand and we will keep you informed every step of the way.

A lot of our patients are curious about the difference between an orthodontist and a dentist. In fact, one of the most common questions we hear at Orthodontic Specialists of Southeastern Massachusetts is, “Dentists and orthodontists are all the same, right?”

A general dentist is your primary dental care provider. Dentists diagnose, treat, and manage your overall oral healthcare needs, including gum care, root canals, fillings, crowns, veneers, and bridges.

Orthodontists, such as Dr. Neil Oliveira and Dr. Derek Wolkowicz, are more concerned with diagnosis, prevention, interception, and treatment of malocclusion, or what we call “bad bite,” of the teeth. Orthodontists focus on tooth and jaw alignment and bite problems such as overbites and underbites, and are responsible for straightening teeth via bands, wires, braces, and other fixed or removable corrective treatment options, like braces and clear aligners. Orthodontists treat children as well as adults who wish to improve the function of their bite and appearance of their smile.

Before becoming an orthodontist, doctors such as Dr. Neil Oliveira and Dr. Derek Wolkowicz start out in dental school and earn a dental degree, just like your general dentist. After dental school, those doctors who decide they are interested in the orthodontic field, stay in school for a few more years and become experts in orthodontia, which is one of nine specialties within the dental field.

Isn’t it nice to know we have orthodontic experts here at Orthodontic Specialists of Southeastern Massachusetts to help you through any type of treatment your teeth and jaw might need? To schedule your initial appointment at our New Bedford or Mattapoisett, MA office, please give us a call today!
