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!

Sports are great for children for a variety of reasons. Children can develop their motor skills, learn how to solve conflicts and work together, and develop their work ethics. As a parent, you may recognize the benefits of sports, but also naturally worry about your child’s health and safety. Your job goes beyond providing a water bottle and making sure your child follows the rules of the game.

Although you may not think of your child’s teeth first when you think about sports, accidents can happen that affect your children’s teeth. A stray hockey stick, an errant basketball, or a misguided dive after a volleyball are examples of ways a child could lose a tooth. In fact, studies show that young athletes lose more than three million teeth each year.

Becoming a Better Athlete to Protect Teeth

Becoming a better athlete involves refining skills, learning the rules of the game, and being a good sport. These components are not just about winning. They are also about safety. Young athletes who are better ball-handlers and who are careful to avoid fouls and penalties are less likely to have harmful contact with the ball, teammates, or opponents. Children who are better roller-bladers are less likely to take a face plant into the blacktop, and more likely to save their teeth. Being a good sport and avoiding unnecessary contact is one way to protect teeth.

Proper Protective Equipment for Teeth

If your child is in a sport that poses a high threat to teeth, it is essential for your child to wear a mouthguard. Mouthguards fit your child’s mouth and consist of soft plastic. Dr. Neil Oliveira and Dr. Derek Wolkowicz can custom fit a mouthguard if generic ones are uncomfortable. While children may resist wearing a mouthguard initially, your persistence in insisting that they wear it should be enough to convince them. A helmet or face mask provides additional protection.

While prevention is best, rapid treatment can improve the situation if your child does happen to lose a tooth during sports. Rapid implantation can work in about ten percent of cases. To learn about ways to save a lost tooth, contact our New Bedford or Mattapoisett, MA office.
