Now that October is upon us, Dr. Kathleen Chan and Dr. Ivy Chen and our team at Chan & Chen Orthodontics wanted to send you a friendly reminder to schedule your orthodontic appointment prior to the end of the year to take full advantage of any flex spend, health savings, or insurance benefits that you may have.

The end of the year is always a busy time so make your appointment now so you don’t lose your available benefits! Give us a call today!

Let’s talk science! From the vastness of the cosmos to sub-atomic particles, science helps us understand the world around us and how it works. So, let’s take some familiar scientific fields of study and apply them to your toothbrush.

My toothbrush?

Yes, indeed! When it comes to your oral health, your toothbrush is the first line of defense, so understanding how and why it works so well might help us use this handy tool even more effectively.

Biology—the study of living organisms

Unfortunately for your toothbrush, the living organisms we’re talking about here are the bacteria which cause tooth decay and those which can lead to illness. How do these problems arise, and how do we prevent them?

Fight Plaque

Plaque is the sticky film that builds up on teeth, and millions of oral bacteria help make up this biofilm. These bacteria convert sugars and other carbohydrates in the foods we eat into acids. And these acids erode our tooth enamel, leading to tooth decay. (More on this when we get to Chemistry.) The best ways to get rid of plaque?

• Brush often. The recommended minimum is two minutes of brushing twice a day, but when you’re having orthodontic work done, it’s even more important to banish the plaque that can stick to your braces or inside aligners. Ask us what brushing schedule is best for you.
• Try an electric toothbrush. For some people with braces, cleaning the teeth is easier and more thorough with an electric brush.
• Replace your brush regularly. Brushes become worn and frayed after three or four months, and you won’t be brushing as effectively.

Stop Germs from Spreading

• Don’t share. Sharing toothbrushes can lead to an increased risk of colds and infections.
• Rinse thoroughly after brushing, making sure you remove any toothpaste or debris left after you brush.
• Store the brush upright and let it air-dry. Covering the brush or keeping it in a closed container can promote the growth of bacteria more easily.
• Keep different brushes separate when they’re drying to avoid cross-contamination.
• Replace your brush regularly!

Chemistry—the study of what makes up substances, their properties, and how they interact

When it comes to improving your brushing chemistry, the best thing you can do for your toothbrush is to put a dab of fluoride toothpaste on it! Why fluoride? Let’s look at the chemistry of tooth enamel.

Tooth enamel is the strongest substance in our bodies—even stronger than bone. But it is not indestructible, and acidic substances can dissolve the mineral bonds which give our enamel its strength, whether they come from the bacteria in plaque or are found in our favorite foods and drinks (sodas, coffee, tomatoes, and citrus are among the tasty, but acidic, culprits).

The enamel in our teeth contains calcium and phosphate ions, minerals which help make it the strongest substance in our bodies. But when the level of acidity in our mouths becomes too high, these minerals begin to dissolve. Eventually, teeth become pitted, bacteria can penetrate more deeply, and decay is the result.

So what can we do? While our saliva helps neutralize acidity naturally, and we can cut back on acidic foods in our diets, using fluoride toothpaste actually helps restore the strength of our enamel in a process known as “remineralization.”

Fluoride works on the surface of enamel to both attract and anchor calcium ions, reducing mineral loss and strengthening the weakened enamel. Fluoride also interacts with the calcium and phosphate compound to create a new compound that is even stronger and more acid-resistant.

When you brush with fluoride toothpaste, you help replace and restore the mineral composition of your enamel—and there’s evidence that fluoride might even interfere with oral bacteria’s ability to produce acid. Now that’s good chemistry!

Physics—the study of matter and energy and their interactions

The matter here is your tooth enamel, and the energy is the force you use when brushing. And this is one time the force should not be with you.

• Over-vigorous brushing can not only damage your brackets, but can also irritate delicate gum tissue and wear down enamel. A “sawing” back-and-forth motion is both hard on your enamel and misses plaque and debris between the teeth. We’ll be happy to show you the safest and most effective way to brush with braces. Just remember, “Massage, don’t scrub.”
• A soft toothbrush is almost always your best option when you use a manual brush, but if you’re still a heavy-handed brusher, or have sensitive teeth and gums, consider an electric model. An electric toothbrush should provide a continuous brushing motion without needing any heavy pressure from the brusher. Some models will even let you know when you are brushing too hard.

Brushing harder is not brushing better, and your teeth, gums, and braces will be heathier with careful brushing habits. If you need tips on brushing with braces, contact our Andover office and ask!

There’s a lot of science in the simple act of brushing, but we don’t need to spend hours studying to get a passing grade in dental health. The things you do normally—brushing at least two minutes twice a day, using fluoride toothpaste, and applying proper brushing technique—will help create a smile which will earn you top marks from Dr. Kathleen Chan and Dr. Ivy Chen for a lifetime!

Well, of course you can chew gum and wear braces. But, should you chew gum and wear braces? That can be a sticky question.

For many years, the answer was a firm “No.” Not only did our favorite chewables literally gum up the (dental) works, but they were filled with loads of the sugar that cavity-causing bacteria love to feed on. The result? A much better chance of damage to your orthodontic work, and a higher risk of cavities near your brackets and wires.

But times, and gum recipes, change. Today’s sugar-free gum provides us with some new ideas to chew over.

• Sugarless gum is much less sticky than regular gum, so it is much less likely to stick to your appliance. If there is any chance that gum will damage your wires or brackets, we’ll let you know that it’s best to wait until your braces are off to indulge.
• Some orthodontic patients find that their jaws and ligaments are less sore if they chew gum for a few minutes after an adjustment.
• Most important, studies suggest that chewing sugarless gum might actually help prevent cavities from forming. How is that possible?

Because chewing gum increases our production of saliva! Okay, we don’t normally find saliva an exciting, exclamation-point-worthy topic, but let’s look at the dental benefits:

• Saliva washes away food particles and bacteria. And because braces can trap food when we eat, it’s great to have some help washing away any meal-time souvenirs.
• Saliva helps neutralize acids in the mouth. The acids found in foods and produced by oral bacteria lead to cavities, so diluting and neutralizing their effects provide important protection for our enamel.
• Saliva helps bathe the teeth in minerals that can actually rebuild weakened enamel. Acids in the mouth attack minerals in the enamel such as the calcium and phosphate that strengthen our teeth. Fortunately, saliva provides calcium, phosphate, and fluoride that can actually help rebuild weakened enamel.

So, should you chew gum and wear braces? The real question is, should you chew gum while you’re in braces? Dr. Kathleen Chan and Dr. Ivy Chen and our team are more than happy to provide the right answer for you! Talk to us at your next visit to our Andover office about the potential benefits and drawbacks of dentist-approved sugarless gum. Depending on the kind of gum you choose and the kind of orthodontic work you are having done, the answer just might surprise you.

Happy Fall, everyone! Even though fall has not officially begun, we are super excited to get our fall decorations up around the office. We love fall but more importantly, we love sweater weather season! We are happy to celebrate new additions to our office family! Both Betsy and Natalie welcomed new additions this month! We are wishing each of them lots of rest!

With school starting, we want to give our patients updates to scheduling and safety protocols during the flu season. During this time, we have after-school and Saturday appointments available for all of our students. Although there may be certain appointments that will need to be during a weekday morning, we will try our best to accommodate. We promise to do our best to meet your scheduling needs. 

With COVID-19 cases going up once again and the start of flu season, we continue to take our safety protocols seriously. The dental environment is one of the safest when it comes to COVID-19 protocols. As a profession, we have always been obsessed with infection control. We have multiple hand sanitizing stations and air purifiers throughout the office. Our central HVAC system is also amplified with extra filtering for everyone’s safety. Please wear a mask when you come, regardless of your vaccination status. We are doing our best to ensure we are respecting everyone’s safety during this time. And, since masking up is still normal, now is the perfect time to straighten your teeth if you are self-conscious about treatment!

As we start getting closer to the holiday season, we will be excited to share all of our favorite traditions. But for now, we are excited for National Coffee Day on September 29th! Iced coffee seems to be a team favorite across the board in our office, even when it's super cold outside. However, we do want to caution all of our patients that drinking coffee often is not great when it comes to staining teeth. For those in treatment with Invisalign, remember to take aligners out when drinking and eating. For this reason, try to avoid sipping beverages throughout the day to limit the amount of time your aligners are out of your mouth. 

We hope to see everyone soon and cannot wait to see everyone’s beautiful smiles!
