Why all the fuss about fluoride? Your dentist recommends it, your toothpaste is formulated with it, most of our drinking water contains it. Just what is it about this mineral that makes dental professionals sing its praises? Read on for three good reasons why fluoride is a healthy choice for healthier teeth.

1. Fluoride Works!

Fluoride is an attractive option for protecting your teeth—and we mean that literally. Fluoride protects the surface of your teeth by working on a molecular level to attract minerals which strengthen enamel and help prevent cavities.

Our tooth enamel is mostly made from calcium and phosphate ions. These elements combine to form hydroxyapatite, strong crystals which make up about 95% of our enamel. Hydroxyapatite is so strong, in fact, that tooth enamel is the hardest part of our bodies. What can go wrong?

Acids. Acids created by the bacteria in plaque and the acids in our diet strip away the calcium and phosphate ions in enamel, weakening the surface of the tooth. This process is called demineralization. Over time, weak spots become bigger as acids eat through enamel to the inner tooth, causing decay and cavities.

So, what can fluoride do?

First, fluoride helps remineralize tooth enamel. Fluoride is attracted to the tooth’s surface and bonds with its minerals. It also attracts the calcium and phosphate ions that are found in our saliva to restore any minerals that have been lost. This process helps repair any weak spots that might have begun to form.

But fluoride does more than restore and repair tooth strength—it improves it! Fluoride ions join with calcium and phosphate to form fluorapatite crystals, which are larger and stronger than hydroxyapatite crystals. Even better? These new crystals are more resistant to acids.

2. Fluoride Is Doubly Effective

Fluoride works both externally and internally. We just looked at how fluoride helps keep teeth strong when applied to the outside of the teeth. This is called a topical application. Systemic benefits come the fluoride we consume in our diets.

Fluoride isn’t found in many foods, but it is found naturally in lakes, rivers, and other water sources. When the local water’s fluoride level is low, many communities add fluoride for its proven ability to prevent cavities. Water fluoridation is safe, has been studied for decades, and has been shown to reduce the risk of cavities by 25% or more for both children and adults.

Systemic fluoride was important when you were younger and still had your baby teeth. This is because fluoride joined with minerals in your adult teeth while they were growing and developing, creating stronger, more cavity-resistant teeth even before they erupted.

And now that your permanent teeth are here, you’re still in luck! When you drink fluoridated water, you’re increasing the amount of fluoride in your saliva. Just like fluoride toothpaste, saliva bathes your teeth with fluoride ions, remineralizing and strengthening the tooth surface and helping repair weak spots in your enamel.

3. It’s Easy to Get Fluoride Protection

Because so much of our drinking water is fluoridated, most of us really don’t have to think about how to get the recommended amount of fluoride in our diet each day. If your community’s water is low in fluoride, Dr. Cronin can help you. Prescription fluoride rinses, gels, supplements, and other treatments are available at our Langley orthodontic office to make sure that your teeth are well-protected, wherever you may live. We will let you know which products are best for you and how often to use them.

Most toothpastes are formulated with fluoride, so you’re getting the enamel-strengthening benefits of this mineral every time you brush. Keeping up with your brushing is especially important while you’re in orthodontic treatment.

Because wearing traditional braces can mean it’s harder to reach all the plaque on your teeth, especially behind wires and around your brackets, that demineralization we talked about earlier is a common problem during treatment. Demineralization often leads to discolored white spots on enamel and, eventually, cavities. If you need more protection than toothpaste alone provides, Dr. Cronin will suggest fluoride treatments to reduce the risk of demineralization and even reverse some of its effects.

Fluoride isn’t, of course, the only way to look out for your dental health. Proper brushing and flossing are still essential for removing plaque. And sealants for both kids and adults provide long-lasting protection for chewing surfaces. But when it comes to a proven cavity-fighter that’s simple to use, effective, and easily available—is it any wonder we’re big fans of fluoride?

If your teeth don't line up like they used to any more, you may be suffering from temporomandibular joint disorder, often called TMD. This is a term that can actually be applied to any condition that occurs because the temporomandibular joint (TMJ) is inflamed.

The temporomandibular joint is essentially the hinge that holds your lower jaw to your skull, and when it is inflamed or damaged in any way, it can be extremely painful. You have two temporomandibular joint, one on each side of your jaw, and it is typical to experience TMD in both sides at the same time.

Shifting of the Teeth

The reason that your teeth may not line up as they once did is that the ball and socket joints are often out of alignment and, as mentioned above, often very inflamed as a result. In order to correct the problem, Dr. Cronin may prescribe dental orthotics such as a lower jaw splint.

Sometimes, the wisdom teeth can play a role in the shifting of the teeth as well. If shifting wisdom teeth is combined with TMD, it may be necessary to have your wisdom teeth removed. Dental splints may follow if your teeth don't shift back to their proper positions on their own.

TMD is certainly a difficult thing to deal with, so if you experience your teeth shifting, scheduling an appointment at our Langley office is the smartest course. We want to help you get your smile back, so give us a call anytime.

Temporomandibular dysfunction (TMD) refers to a diverse range of disorders that relate to muscular function in the jaw and face — the temporomandibular joint (TMJ). That could mean difficulty opening your mouth, pain in the jaw or face, or any sort of problem with the jaw joint.

TMD can be difficult to diagnose because of the varied causes. Whatever the case, an accurate diagnosis from Dr. Cronin helps make treatment as successful as possible.

Most often, jaw problems will resolve themselves within several weeks or months. Surgeries like arthrocentesis, arthroscopy, and open-joint surgery should be a last resort. More conservative and reversible treatments should come first and are in fact the most critical step in the treatment of TMD.

Less invasive treatments like acupuncture and splints can be helpful, but that will depend on your particular case. It’s worth your while to speak with Dr. Cronin at our Langley office to learn about solutions that could work for you.

A combination of treatments will most often produce the greatest relief for TMJ patients. It’s a good idea to avoid activities that overuse the jaws, such as chewing gum or clenching your jaws.

You can be proactive in finding relief for TMD by trying the following remedies at home:

• Eat soft food: When you eat soft and/or blended food, your jaw gets an opportunity to rest. Avoid chewy and crunchy food, and food that requires you to open your mouth wide, like apples or corn on the cob.
• Apply moist heat: A hot water bottle wrapped in a moist towel can help reduce symptoms.
• Apply ice: Applying an ice pack wrapped in a cloth or towel for no longer than 15 minutes may also reduce pain and promote healing.
• Do jaw exercises: A physical therapist can help identify the exercises that will work for you. Jaw exercises have been shown to be an effective treatment method that can be performed at home.
• Relaxation: Actively try to relax the muscles of the face and lips, and let your teeth come apart. Many find meditation, yoga, and slow, deep breathing to be helpful for reducing stress and tension.
• Avoid wide yawns: Keep your fist under your jaw when you feel a yawn coming on, to keep your jaw from opening too widely.

From the time you were small, you’ve been warned about the dangers of plaque. Why? Because:

• It’s an unpleasant film that sticks to your teeth
• It causes cavities
• It causes gum disease
• It can cause extra problems when you wear braces

And really, do we need to know much more than this to motivate us to brush? But if you’re in a curious mood, you might be wondering just how this soft, fuzzy film accomplishes all that damage. Let’s take a closer look at the sticky problem of plaque.

How does plaque form?

We live with hundreds of species of oral bacteria, most of which are harmless, and some of which are actually beneficial. But when our oral ecosystem gets out of balance, problems can occur. For example, without regular and thorough brushing and flossing, we start to build up plaque.

Plaque starts forming within hours of your last brushing. And even though plaque fits the very definition of “seems to appear overnight,” this biofilm is actually a complex microbial community with several different stages of development.

• It starts with saliva.

Saliva is vital to our oral health, because it keeps us hydrated, washes away food particles, neutralizes acids in the mouth, and provides minerals which keep our enamel strong. Saliva also contains proteins, which help form a healthy, protective film on the tooth surface. This film is called a pellicle.

• Bacteria attach to the pellicle.

There are species of oral bacteria that are able to attach themselves to the pellicle film within hours of its formation. As they become more firmly attached, they begin to grow and divide to form colonies, and are known as the early colonizers of the plaque biofilm.

• A complex biofilm forms.

If you’ve skipped brushing for a few days (please don’t!), you’ll notice a fuzzy, sometimes discolored film on your enamel—that’s a thriving plaque community, and it only takes a matter of days to go from invisible to unpleasant.

If you’re not removing plaque regularly, it can harden further and become tartar. And once you have tartar buildup, you’ll need the care of a dental professional to remove it.

• What happens if we ignore plaque and tartar?

We get cavities and gum disease.

How does plaque cause cavities?

• The bacteria in plaque, like all organisms, need nutrients.

Our normal oral environment and the food in our everyday diets provide the nutrients plaque needs. And, as we mentioned above, certain types of oral bacteria convert these nutrients into acids. Foods such as carbohydrates, starches, and sugars are most easily converted into acids, which is why we recommend that you enjoy them in moderation.

• The biofilm promotes acid production.

Within the plaque film, anaerobic bacteria (bacteria which don’t use oxygen) convert sugars and starches into acids. As the plaque film becomes denser, it blocks acid-neutralizing saliva and oxygen from reaching these bacteria close to the tooth’s surface, creating an ideal environment for the bacteria to produce their acid waste products.

• Acids attack enamel.

The sticky nature of plaque keeps these acids in contact with tooth enamel, where, over time, acids dissolve minerals in enamel, weakening the mineral structure of the tooth.

How does plaque cause gum disease?

• Bacteria cause inflammation and gingivitis.

The bacteria in plaque irritate the delicate tissue of the gums, which causes an inflammation response which can leave your gums swollen, red, bleeding, or tender. This early form of gum disease is gingivitis. Fortunately, good dental care and careful brushing and flossing can usually prevent and even eliminate gingivitis.

• Plaque and tartar can lead to periodontitis.

When plaque and tartar build up around and below the gumline, the gums pull away from the teeth, leaving pockets where bacteria collect, leading to infection as well as inflammation. Infections and constant inflammation not only harm gum tissue, they can destroy the bone supporting the teeth. This serious gum condition is periodontitis, and should be treated immediately to avoid further infection and even tooth loss.

How does plaque affect orthodontic patients?

• Plaque collects around your braces.

Braces provide plenty of spots for plaque to hide from your brush. If you aren’t extremely diligent with your brushing and flossing, plaque collects near brackets, wires, and bands—all those spots that a brush and floss find difficult to reach.

• Plaque promotes demineralization

The demineralization process we mentioned above can cause white spots on teeth (decalcification), where minerals have dissolved. Sometimes these spots can be treated, and sometimes they are permanent. They can become quite sensitive, and may lead to cavities.

Careful brushing and flossing around your braces will help eliminate the plaque that can cause demineralization near brackets. Ask Dr. Cronin about the tools and the brushing and flossing techniques which will give you the best results.

How do we fight plaque?

From the time you were small, you’ve learned how to fight plaque:

• Brush at least twice a day for two minutes, and be sure to brush all of your tooth surfaces and around the gumline.
• Floss to remove plaque from between the teeth and near the gumline.
• See your dentist as recommended for a thorough professional cleaning.

Be proactive. If you have any questions, talk to us at our Langley office about the best way to keep plaque at bay. We can show you the most effective ways to brush and floss, recommend anti-plaque toothpastes and rinses, even suggest plaque-revealing tablets if you’re missing some trouble spots.

We’ve only brushed up on some plaque basics, because there is a lot more to discover about this complex biofilm. Happily, even with all there is to learn about plaque’s growth and development, it’s reassuring to know that getting rid of it is quite simple—with just a soft-bristled brush, some dental floss, and a few minutes of your time each day, you’re on the way to a healthy, happy, plaque-free smile.
