If Dr. Kathleen Chan and Dr. Ivy Chen and our team at Chan & Chen Orthodontics have recommended a palatal expander, you might be wondering what it is and how it will help you. A palatal expander is a small appliance fitted in your mouth to create a wider space in the upper jaw. It is often used when there is a problem with overcrowding of the teeth or when the upper and lower molars don’t fit together correctly. While it is most commonly used in children, some teens and adults may also need a palatal expander.

Reasons to get a palatal expander

There are several reasons you might need to get a palatal expander:

• Insufficient room for permanent teeth currently erupting
• Insufficient space for permanent teeth still developing which might need extraction in the future
• A back crossbite with a narrow upper arch
• A front crossbite with a narrow upper arch

How long will you need the palatal expander?

On average, patients have the palatal expander for four to seven months, although this is based on the individual and the amount of correction needed. Several months are needed to allow the bone to form and move to the desired width. It is not removable and must remain in the mouth for the entire time.

Does it prevent the necessity for braces?

The palatal expander doesn’t necessarily remove the need for braces in the future, but it can in some cases. Some people only need braces because of a crossbite or overcrowding of the teeth, which a palatal expander can help correct during childhood, when teeth are just beginning to erupt. However, others may eventually need braces if, once all their permanent teeth come in, they have grown in crookedly or with additional spaces between.

Did you know that even in ancient times, people wanted to improve the look and function of their smiles? Chan & Chen Orthodontics thinks of modern orthodontic appliances as sleek, efficient technology, but this was not always so! Take a look at the highlights in the evolution of braces.

Ancient Times: From Greece to Rome

• According to The Angle Orthodontist, Aristotle and Hippocrates first thought about methods for straightening teeth between 400 and 300 BC.
• The Etruscans, in what we now know as Italy, buried their dead with appliances that maintained spaces and prevented collapse of their teeth and jaws during life. Archaeologists have discovered mummified remains in various locations that have metal bands wrapped around the teeth.
• A Roman tomb has also been discovered in which the teeth were bound with gold wire, including documentation on the wire’s use as a dental device.

18th Century: A French Development

• The French dentist Pierre Fauchard is acknowledged as the father of modern dentistry. In 1728 he published a book that described various methods for straightening teeth. Fauchard also used a device known as a “blandeau” to widen the upper palate.
• Louis Bourdet was another French dentist who published a book in 1754 that discussed tooth alignment. Bourdet further refined the blandeau and was the first dentist to extract bicuspids, or the premolar teeth between canines and molars, for the purpose of reducing tooth crowding.

19th Century: Orthodontics Defined

• Orthodontics started to become a separate dental specialty during the early 19th century. The first wire crib was used in 1819, marking the beginning of modern orthodontics.
• During this period, gold, platinum, silver, steel, gum rubber, vulcanite, and occasionally wood, ivory, zinc, and copper were used — as was brass in the form of loops, hooks, spurs, and ligatures.
• Edward Maynard first used gum elastics in 1843 and E. J. Tucker began making rubber bands for braces in 1850.
• Norman W. Kingsley published the first paper on modern orthodontics in 1858 and J. N. Farrar was the first dentist to recommend the use of force over timed intervals to straighten teeth.

20th Century: New Materials Abound

• Edward Angle developed the first classification systems for malocclusions (misaligned teeth) during the early 20th century in the United States, and it is still in use today. Angle founded the American Society of Orthodontia in 1901, which was renamed the American Association of Orthodontists in the 1930s.
• By the 1960s, gold was universally abandoned in favor of stainless steel.
• Lingual braces were the “invisible” braces of choice until the early 1980s, when tooth-colored aesthetic brackets made from single-crystal sapphire and ceramics became popular

Today

As we arrive in the present, you need only look at your own braces to see how far we’ve come. Your treatment plan was probably created with a 3D digital model, and we’ve likely used a computerized process to customize your archwires. Perhaps you have clear aligners, self-ligating brackets, or highly resilient ceramic brackets with heat-activated wires.

Orthodontics has come a long way from the days of Aristotle, and even the bulky wrap-around braces of just 60 years ago. Regardless of your specific treatment plan, the development of high-tech materials and methods has made it possible for your orthodontic experience to be as effective, efficient, and comfortable as possible.

Valentine’s Day, also known as Saint Valentine’s Day, has been said to originate with a Catholic priest named Valentine several thousand year ago. Valentine defied the emperor at the time by secretly marrying men and their brides after the emperor had made it illegal to marry. Emperor Claudius II did this because he wanted as many single young men to fight in his war as he could get.

Valentine disobeyed the emperor’s edict by continuing to marry couples until he was sentenced to death. Before his execution, he sent a letter to a secret love and signed it “From your Valentine.” Dr. Kathleen Chan and Dr. Ivy Chen and our team have come up with some suggestions on how you can celebrate this Valentine’s Day, whether you have a valentine of your own or not.

Valentine's Day Ideas

• Enjoy a tasty treat. There are plenty of options when it comes to cooking and/or baking on Valentine’s Day. Make your significant other his or her favorite meal or sweet treat, or make your own favorite dish to enjoy on this day. Oh, and be sure to make enough for leftovers!
• Make a personalized card. Instead of buying a card from the grocery store, take the time to make your own for a loved one. People love handwritten notes, especially when it’s from someone special. If you’re single this Valentine’s Day, make a card for fellow single friend to brighten the day and remind the person that he or she is also loved.
• Watch a movie. We all know there are plenty of romance movies out there. Put on your favorite romantic comedy, or pick up your significant other’s favorite movie to watch together. Even better, if you’re single, pick up your own favorite movies to watch to pass the time this Valentine’s Day.
• Do nothing! We all know Valentine’s Day can sometimes get a lot of hype. If you’re worried about not making a reservation in time, don’t feel like planning an extravagant night out, or simply not in the holiday mood this year, spend your day sitting back and relaxing.

Valentine’s Day is a time to celebrate love and spend quality hours with the people you care about the most. Whether you’re in a relationship or single, take some time today to appreciate those you love in your life.

We wish you a happy Valentine’s Day celebration and look forward to seeing you at our Andover office during your next appointment.

Valentine’s Day is the holiday to celebrate all the treasured relationships in your life. It’s a time to honor love in all shapes and forms with cards, social gatherings, and sometimes even binge eating of sweets.

It's hard to look the other way when grocery stores and pharmacies are invaded with goodies connected to the Valentine’s Day theme, and especially if you’re on the receiving end of some of these sweets. We get it. In fact, we’re all for it!

However, we also support a cavity-free smile. So in the interest of your dental and general health, and because we think it’s genuinely tasty, Dr. Kathleen Chan and Dr. Ivy Chen recommends an alternative to the Valentine treats you may be accustomed to: dark chocolate. 

Yes, Healthy Chocolate Exists

Studies have shown that dark chocolate is high in flavonoids, an ingredient found in the cocoa beans used to make chocolate. Flavonoids can help protect the body against toxins, reduce blood pressure, and improve blood flow to the heart and brain.

By opting for dark chocolate rather than milk chocolate, you get to reap these benefits! Pretty sweet, right? Just make sure to stick to high-quality dark chocolates that have undergone minimal processing.

Dark Chocolate, AKA Protector of Teeth

Not only does dark chocolate provide some nice benefits for your overall health, it also helps protect your teeth against cavities! According to the Texas A&M Health Science Center, dark chocolate contains high amounts of tannins, another ingredient present in cocoa beans.

Tannins can actually help prevent cavities by interfering with the bacteria that causes them. Think of them as scarecrows for bacteria. They don’t always prevail, but isn’t it nice to have them there?

Smooth Never Sticky

Unlike many popular candies, dark chocolate is less likely to stick in the crevices of your teeth. Chewy, gooey sweets are more likely to hang around in your mouth for longer periods of time, which means they raise the odds of your harboring cavity-creating bacteria.

While some dark chocolates have additives like caramel or marshmallow, it’s best to opt for the plain varieties, which are just as delicious. If you’re feeling festive, though, a dark chocolate with caramel is still better than a milk chocolate with caramel, so that’s the way to go!

While dark chocolate has some pretty sweet benefits, the most important thing to remember (whether you go the dark chocolate route or not), is that moderation is key. That being said, we hope you have fun satisfying your sweet tooth and shopping for treats for your friends and loved ones. Happy Valentine’s Day from all of us at Chan & Chen Orthodontics!
