June is Great Outdoors Month and we all love being outdoors! From Camping, to hiking, to swimming, all our team members love to spend time outdoors. 

This summer we plan on spending as much time as we can outdoors, air quality permitting. Some of our team members have planned camping trips while others are excited to go for a walk in the state parks. We love to explore Harold Parker State Forest and one of our favorite beaches, Nahant! Or anywhere in New Hampshire and Maine is beautiful.  

Let us know if you have any favorite spots during your next visit or on our Facebook page!

Every year, Americans all over the world celebrate the birth of the country and its independence on the Fourth of July. There are countless ways that people celebrate and they range from community parades and large scale gatherings to concerts, fireworks displays, and smaller scale celebrations among family and friends. For some people, July 4th is synonymous with baseball, while for others it is all about the beach of barbecues. However you celebrate, you can be sure that red, white, and blue is visible everywhere throughout the area.

The Beginnings of Fourth of July Celebrations

Although it wasn't officially designated as a federal holiday until 1941, the actual tradition of celebrating Independence Day goes back to the time of the American Revolution (1775 – 1783). At the time of the American Revolution, representatives from the 13 colonies penned the resolution that ultimately declared their independence from Great Britain. The continental congress voted to adopt the Declaration of Independence on July 2nd of 1776. Two days later, Thomas Jefferson's famous document that is now known as the Declaration of Independence, was adopted by delegates representing the 13 colonies.

First States to Recognize the Fourth of July

In 1781, Massachusetts became the first state (or commonwealth) whose legislature resolved to designate July 4th as the date on which to celebrate the country's independence. Two years later, Boston became the first city to make an official designation to honor the country's birth with a holiday on July 4th. In that same year, North Carolina's governor, Alexander Martin, became the first governor to issue an official state order stipulating that July 4th was the day on which North Carolinians would celebrate the country's independence.

Fun Facts About the Fourth of July

• The reason the stars on the original flag were arranged in a circle is because it was believed that would indicate that all of the colonies were equal.
• Americans eat over 150 million hot dogs on July 4th.
• Imports of fireworks each year totals over $211 million.
• The first “official” Fourth of July party took place at the White House in 1801.
• Benjamin Franklin didn't want the national bird to be the bald eagle. He believed that the turkey was better suited to the coveted distinction. John Adams and Thomas Jefferson disagreed with him, and he was outvoted, so the bald eagle became the official bird of the United States.

For many, the tradition is something entirely different. Along the coastal areas of the United States, people may haul out huge pots to have lobster or other types of seafood boils. Others may spend the day in the bleachers at a baseball game, or at a park, cooking a great traditional meal over an open fire. No matter how or where you celebrate, one thing is certain: all Americans celebrate July 4th as the birth and independence of our country.

Dr. Kathleen Chan and Dr. Ivy Chen and our team at Chan & Chen Orthodontics wish you a safe and happy Fourth of July!

When does an underbite need surgery? The short answer is: when Dr. Kathleen Chan and Dr. Ivy Chen and our team recommend surgery as the best way to give you a healthy, functional bite. But let’s take a longer look, and see just why your doctors might come to that conclusion.

• First, what exactly is an underbite?

In a perfect bite, the upper and lower jaws align, well, perfectly. Upper teeth overlap lower teeth very slightly, upper and lower teeth meet comfortably, and jawbones and joints function smoothly. When the alignment is off, it causes a malocclusion, or “bad bite.”

When we talk about an underbite, or Class 3 malocclusion, it means that the lower jaw protrudes further than the upper jaw. This protrusion causes the bottom teeth and jaw to overlap the upper teeth and jaw.

• What causes an underbite?

Sometimes an underbite is caused by childhood behaviors while the teeth and jaw are developing, including tongue thrusting or prolonged thumb-sucking and pacifier use. (Working to stop these behaviors before they affect tooth and jaw formation is one of the many good reasons children should have regular visits with their dentists and pediatricians.)

Most underbites are genetic, however, and tend to run in families. It’s estimated that from five to ten percent of the population has some form of underbite. The lower jawbone (mandible) might be overdeveloped, the upper jawbone (maxilla) might be underdeveloped, both bones could be affected, or, sometimes, tooth size and placement might cause an underbite. These irregularities in jaw shape and size and/or tooth crowding are not something that can be prevented, and require professional treatment.

• Why? What’s the problem with an underbite?

Even a minor underbite can cause difficulties with biting and chewing. A more severe underbite can lead to speech problems, decay and loss of enamel where the teeth overlap, mouth breathing and sleep apnea, persistent jaw and temporomandibular joint pain, and self-confidence issues.

• Can’t my dentist treat my underbite?

Most probably not. A very mild underbite can be camouflaged cosmetically with veneers, but this does not address the cause of the underbite, and will not work for moderate or severe underbites.

• Can my orthodontist treat my underbite?

Dr. Kathleen Chan and Dr. Ivy Chen will create an underbite treatment plan after a detailed study of each patient’s individual dental and skeletal structure. Treatment options will vary depending on the cause of the underbite, its severity, and even the patient’s age.

Early intervention is especially important for children who show signs of an underbite. That’s why we recommend that children visit our Andover office by the age of seven.

If an underbite is caused by tooth misalignment or crowding, braces can reposition the lower teeth. Sometimes extractions are necessary to make room for proper alignment.

If the cause is due to jaw structure, children’s bones are still forming, so treatment can actually help correct bone development. Palatal expanders, headgear, and other appliances are various methods of encouraging and guiding bone development.

But braces and appliances aren’t effective for every patient with an underbite, and especially in patients (usually those in their late teens and older) when the jawbones are already fully formed. In this case, we might suggest coordinating treatment with an oral and maxillofacial surgeon.

• What does an oral and maxillofacial surgeon do?

An oral surgeon has the training, experience, and skill to help correct an underbite by surgically reshaping and repositioning the jawbone. This corrective jaw surgery is called orthognathic surgery.

• What will happen during orthognathic surgery?

Your treatment will be tailored to your specific needs. Two of the common surgical procedures for treating an underbite involve repositioning the upper jaw to lengthen it and/or reshaping the lower jaw to shorten it.

Bone is sometimes removed or added, small bone plates or screws are sometimes used to stabilize the bone after surgery—your surgeon will let you know exactly which procedures will give you a healthy, functional bite. The surgery itself is most often performed under general anesthesia and requires a brief stay in the hospital.

• How will my orthodontist and oral surgeon coordinate my treatment?

Correcting a Class 3 malocclusion can take time. Your oral surgeon will work together with Dr. Kathleen Chan and Dr. Ivy Chen to analyze the interrelationship of teeth, bones, and joints to determine dental and skeletal problems, and will develop the best treatment plan possible to create a healthy alignment.

• So, when does an underbite need surgery?

Sometimes, a minor underbite can be corrected with braces and appliances alone. A serious underbite, however, will often require the specialized skills of both Dr. Kathleen Chan and Dr. Ivy Chen and an oral surgeon.

And, while it’s not the primary purpose of surgery, corrective jaw surgery and orthodontics can also make you happier with your appearance and boost your self-confidence. Achieving a lifetime of beautiful, comfortable, and healthy smiles—that’s the answer to your question.

Well, of course, they already are working for you—as an essential part of the alignment process. Rubber bands, also known as elastic ligatures, are used to secure the wires inside your brackets. But bands can be more than functional. Since the ligatures around each bracket are replaced when you visit our office, why not use that opportunity to choose a new color scheme as well?

• Make a Statement

Bands offer a chance to coordinate your braces to an interest, team, or event. Are you a swimmer? Maybe cool blues and turquoises appeal to you. Batman forever? Black and yellow. (That will work for beekeepers, too.) Have a favorite sports team? Choosing team colors will support your team with every smile. Love your school? Show your spirit by wearing bands in your school colors. Favorite time of year? Celebrate by selecting festive bands in holiday colors.

• Suit Your Mood

Fiery reds and oranges, tranquil blues and greens, millennial purples and pinks, or exuberant neon—you know that there are just some colors that suit your personality. Showcase that personality with your choice of band color. And if your mood changes, choose shades that express a completely different side of you.

• Coordinate Your Colors

Match your bands to your eye color, your makeup, or the clothing colors you choose most often. If there’s a color profile that works for you, make your bands a part of it. If you don’t want everything matching, complement your coloring or clothing with a different but coordinating shade for a cohesive effect.

• Keep a Low Profile

Most adults will stick with a monochromatic set of bands, and this might be a look that appeals to you as well. Grey and silver bands will blend nicely with silver braces. If you have clear or white brackets, you might want to test out which bands will be least noticeable. Clear bands can become discolored, and white bands can make teeth look darker. If there’s a band which mimics your own tooth color, this will be the choice for you.

• Make Color Theory Work for You

Certain colors and tints bring out the best in your tooth color and work with your skin tones. White and yellow bands might make teeth appear duller, and any shade combination that resembles food particles (greens, browns, and black) is probably not a look you’re going for. Have fun with a color wheel and decide which colors you find most flattering.

Make your bands more than a tool—make them an accessory. There are so many colorful options available that you are bound to happen on a color scheme that just suits you. And if you change your mind? Change it up during your next visit to our Andover office!
