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. Kathleen Chan and Dr. Ivy Chen can help you. Prescription fluoride rinses, gels, supplements, and other treatments are available at our Andover 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. Kathleen Chan and Dr. Ivy Chen 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?

October 31—Halloween. Fourth Thursday in November—Thanksgiving. And, in between these two favorite autumn holidays, we have November 1—National Brush Day!

Okay, okay. Maybe National Brush Day isn’t quite as well-known as Halloween or Thanksgiving, but we take any opportunity to celebrate your dental health. So, let’s celebrate brushing!

After all, brushing is vital for healthy teeth and gums.

• Brushing is your first line of defense against plaque. Plaque forms all day long. Plaque sticks to your teeth. Plaque is filled with bacteria which produce cavity-causing acids. Brushing regularly means plaque won’t stay on your teeth long enough to cause serious tooth decay.
• Brushing effectively is especially important while you wear braces. Plaque collects around brackets and can cause enamel discoloration if it’s allowed to build up.
• Brushing is also important for your gum health. Angling your brush to carefully clean plaque and bacteria away from your gum line helps prevent gum disease.

To make the most of the time you spend brushing, let’s take a moment to review some basics on National Brush Day.

Are You Brushing Correctly?

• Big, broad brushstrokes aren’t the answer. Instead, use short up-and-down or circular strokes over each tooth—outside, inside, and on the flat surfaces of your molars.
• Because plaque forms all day, you need to keep on top of it. Brushing at least twice a day for two minutes each time is a good general rule, but doesn’t always hold true during orthodontic treatment.
  • If you wear braces, Dr. Kathleen Chan and Dr. Ivy Chen will probably recommend brushing after each meal or snack to make sure plaque and food particles don’t stick to your teeth and your braces.
  • Take advantage of the special orthodontic brushes that are available if your old brush isn’t cleaning your braces (and your teeth!) as well as you’d like. A brush with a smaller head or different shaped bristles might make all the difference.
  • If you have aligners, you take them out to eat. It’s always a good idea to brush before you replace them. Otherwise, food particles which would normally be brushed away or washed away by saliva are trapped next to your teeth.
• Brushes are meant to clean, not to scrub. You don’t need a heavy hand for cleaner teeth.
• Which also means, there’s almost never a good time to brush with a hard-bristled brush. Hard bristles, along with hard brushing, can actually damage your enamel. Stick to a soft-bristled brush for dental TLC.

Are You Taking Care of Your Brush?

• To clean away bacteria and viruses you might have picked up during the day, wash your hands before brushing and flossing.
• Shake your brush dry when you’re finished and then let it air-dry upright with the handle pointing down. Only use a case for travel, and make sure it has air holes for ventilation. (Bacteria thrive in a wet environment.)
• If your toothbrush lives in the bathroom, close the toilet seat before flushing to avoid airborne particles.
• No matter how close you are to your family members or roommates, don’t share your toothbrush. Sharing doesn’t mean caring in this case—it means sharing germs. Your brush should keep a healthy distance from other brushes as well.
• And no matter how fond you are of your brush, be prepared to replace it often! Most brushes last three to four months at best, because bristles start to fray and can’t clean effectively after several months of use.

It’s no coincidence that National Brush Day comes right after Halloween, the most sugar-filled holiday of them all. So, how can we mark the occasion?

Take a moment to review your brushing habits. Check out the brushes designed for orthodontic treatment. Treat yourself to a new toothbrush. Brushing your teeth properly is one of the easiest things you can do to protect your oral health. That’s something to celebrate!

All Hallows' Eve, more commonly known as Halloween, is a yearly event celebrated on October 31, and one that is anticipated by the young and young at heart all over the world. Some scholars claim that Halloween originated from Celtic festivals that honored the dead or that celebrated the harvest, while others doubt that there's any connection at all to Samhain (a Gaelic harvest festival.) Regardless of its origin, our team at the orthodontist office of Dr. Kathleen Chan and Dr. Ivy Chen hopes that Halloween is fun and enjoyed by all of our awesome patients!

Trick or treat?

In North America, Halloween is predominantly celebrated by children who dress up in costumes, which range from scary to cute, who then go around the neighborhood knocking on doors asking "trick or treat", and they are given candy in return. Trick-or-treating is a time honored tradition, and though many parents groan at the pounds and pounds of candy collected by youngsters and fear for the health of their teeth, there are a few things you can do to help their teeth stay in great shape until the candy is gone:

• Limit the amount of candy they can consume each day
• Have them brush their teeth after eating candy
• Avoid hard, chewy candies as they can stick in hard to brush places
• Keep candy out of sight to reduce temptation
• Don't buy candy too far in advance to limit pre-Halloween consumption
• Help or encourage your children to floss

Halloween Fun

Halloween isn't just about gorging on candy; there are other events associated with this festive day including carving jack-o'-lanterns, painting pumpkins, decorating sugar cookies, bobbing for apples, going to haunted houses, or just curling up on the couch with a bowl full of popcorn and watching some classic, scary movies.

Halloween Around the World

Some countries, like Australia, frown upon Halloween, claiming it is an American event and not based in Australian culture, while others like Italy have embraced the fun and celebrate much as Canadians and Americans do. Mexicans have been celebrating this fun day since around 1960, and it marks the beginning of the Day of the Dead festival. Some countries in Europe have come late to the party, but since the 1990s, countries like Sweden, Norway, and Germany have started celebrating Halloween as well, and finding children in costumes or having ghosts hanging in windows has become commonplace.

Halloween is about fun; stepping outside our normal lives and donning a costume or gathering with friends to knock on doors and ask for candy is as much a part of our culture as hot dogs and barbecue on Labor Day. Have a safe and happy Halloween from the team at Chan & Chen Orthodontics!

We’ll give it to you straight: it can be harder to keep your teeth their cleanest while you’re wearing braces. Food particles play hide-and-seek, plaque builds up around brackets, flossing is harder when you need to maneuver around wires. But keeping your teeth and gums healthy is even more important now that you’re wearing braces.

Why? Because when your braces come off, you want to enjoy the beautiful smile you’ve worked so hard for without worrying about discolored enamel, cavities, or swollen gums. Let’s look at some of the possible consequences when brushing and flossing are more challenging.

Decalcification

If you’ve noticed white spots around your brackets, you’re seeing the signs of decalcification, a common problem for those who wear braces.

Decalcification begins when plaque collects on the enamel around your brackets. The bacteria in plaque produce acids. These acids eat away at the minerals which keep your enamel strong, minerals like calcium and phosphorous. Places on the enamel where erosion takes place are left weakened and discolored.  Eventually, these weak spots can lead to . . .

Cavities

When plaque sticks around, whether near your brackets or anywhere on your teeth, it provides the perfect conditions for decay to develop. Left untreated, bacterial acids continue working away at decalcified spots in your enamel. This continuing erosion causes these surface spots to expand, grow deeper, and become cavities.

If you’re having trouble with built up plaque, and brushing isn’t doing the job for you, your dentist can remove it with a professional cleaning. Getting rid of plaque is healthy not only for your enamel, but your gums as well.

Gum disease

When plaque and tartar collect around the gumline, they irritate delicate gum tissue. This irritation causes gingivitis, or early gum disease. And, while young people rarely suffer from serious gum disease, the pain, redness, bleeding, swelling, and bad breath caused by gingivitis are not anyone’s life goals!

Brushing and flossing are essential to keeping your enamel and gums plaque-free. But even if you brush more often, it’s not as easy as it once was now that you have to work around and between brackets and wires. Luckily, there are lots of tools out there to help you get your teeth, gums, and braces their cleanest.

• Orthodontic toothbrushes

Special brushes designed just for braces can help you work around brackets and wires. V- or U-shaped bristle formations let you brush around and over your braces. Curved bristles can fit under wires. Smaller brush heads let you reach those hard-to-reach places.

• Electric toothbrushes

Many people find these brushes can clean more easily and effectively, especially when wearing braces. Tapered orthodontic brush heads are available, and, if you’re a heavy-handed brusher, there are models which alert you if you’re brushing too hard—protecting your braces and your enamel.

• Orthodontic floss

Special orthodontic flosses can help you do the tricky job of fitting floss behind your wires and between your teeth, or use a floss threader, which helps guide uncooperative floss into tight spaces.

• Water flossers

With their pulsing streams of water, water flossers can reach spots where regular brushes and flosses just can’t comfortably fit. There are even flossers available with special orthodontic tips.

Straight teeth are great. Straight and healthy teeth? Even better! You, Dr. Kathleen Chan and Dr. Ivy Chen, and our Andover orthodontic staff make a great team. Take advantage of our advice and tips for the best tools and techniques to make sure your smile is both perfectly aligned and perfectly healthy once those braces come off!
