Many patients underestimate the importance of wearing their retainers after their braces come off, but it is one of the most critical post care practices to keep your teeth in alignment. Why spend all that time, energy, and money to straighten your teeth when you don't plan to keep them straightened after treatment?

What is a retainer?

As the name implies, a retainer keeps teeth from moving back to the positions in which they started before treatment was administered; they "retain" your smile and bite. There are many different types of retainers—some are removable and some are permanent. Some retainers are made of plastic and metal (known as Hawley retainers) and others are all plastic or all metal. Some retainers can even be bonded to the back of your teeth!

How long do I need to wear it?

If you've been given a removable retainer by Dr. Kathleen Chan and Dr. Ivy Chen, you may be wondering how long you need to wear it. It takes time for the tissues and bones around your teeth to reorganize and set into place after braces treatment.

The amount of time you’ll need to wear your retainer depends on your unique situation, but typically, retainers should be worn at least as long as the time you spent in braces. You might need to wear them full-time for a while, and then transition to wearing them only at night. Dr. Kathleen Chan and Dr. Ivy Chen will have a treatment plan especially for you, and if you stick to it, you'll always have a straight smile.

Nothing is forever (at least without retainers!)

Research has shown that there is no “permanent” position for your teeth to remain in. In fact, some studies say upward of 70% of patients will see a change to their bite and tooth alignment as they get older. This applies to people who have had orthodontic treatment and those who have not. Of course, some people's teeth never seem to shift—you can consider them the lucky ones, as most people's teeth do.

And this is precisely where retainers come in. The only way to ensure your teeth stay in alignment long-term is by wearing your retainers. If you have any questions about retainers or your treatment plan, please ask any member of our Andover staff.

Many smokers believe that chewing tobacco is a safer alternative to smoking cigarettes. This simply isn't the case! In fact, smokeless tobacco can cause serious health concerns.

Smokeless tobacco comes in many forms and goes by many names: dip, snuff, snus, or simply chewing tobacco. Use of these products usually involves sucking or chewing on shredded or loose tobacco leaves, sometimes flavored, for a prolonged period. There are even products that emulate a dissolvable candy-like consistency which are made of compressed tobacco powder.

What are risks and smokeless tobacco?

Whichever form a tobacco product takes, the dangers of using or consuming them is very real. According to a 2007 study by the World Health Organization's International Agency for Research on Cancer, there are upwards of 28 cancer-causing chemicals in smokeless tobacco that are known to cause cancer. And these products are habit-forming just like any other tobacco product that contains nicotine. Using them will increase your risk for many serious diseases including but not limited to: cancer (especially oral and esophageal), gum and heart disease, cavities, and pre-cancerous mouth lesions.

At the end of the day, long-term use of smokeless tobacco can cause serious health issues. These products really take a toll on both your oral and overall health. They put a strain on your immune system and make it less capable of warding off infection and disease.

Dr. Kathleen Chan and Dr. Ivy Chen and our team strongly advise you to stop using smokeless tobacco—or any kind of tobacco product—and not to pick up the habit if you aren't. There is no safe level of tobacco use, smokeless or otherwise.

Need to quit smoking or using smokeless tobacco products?

You can and should always talk to your doctor, healthcare practitioner, or Dr. Kathleen Chan and Dr. Ivy Chen for help quitting. But there are many other resources available today for those who'd like to quit. The National Cancer Institute offers information, support (local and online), and tools to help smokers and smokeless tobacco users quit. They offer live online chat with cessation counselors Monday through Friday and even have a smartphone application available to help people who are serious about quitting.

You can take a look at their website at smokefree.gov or call them toll-free at 1–877–44U–QUIT (1-877-448-7848). There is also help available from your state's quit line at 1-800-QUIT-NOW (1-800-784-8669).

Make the best choice for your health and well-being; avoid the bad habit of tobacco products. If you have any questions about how tobacco related products affect your oral health and hygiene, please don't hesitate to ask one of our Andover staff members.

Having teeth encased in braces can be discouraging during Halloween. If you or your child has braces, there are certain candies to avoid this holiday season—and in general—while you have braces. Candy can be tempting, especially for children.

But don’t worry; other sweet treat options can readily take their place. Take a look at the American Association of Orthodontists’ tips on how to keep your braces safe.

Treats to avoid because they can cause damage to your braces include:

• Hard candies
• Chewy candies
• Nuts
• Caramel
• Licorice
• Jelly beans
• Taffy
• Bubblegum
• Hard pretzels
• Popcorn

These goodies should be avoided because they have the potential to bend or break your braces. Broken brackets and loose wires can waste time and money.

Switch out hard, chewy, and sticky candies for these options in the mean time:

• Soft chocolate
• Peanut butter cups
• Gelatin treats
• Ice cream
• Smoothies
• Root beer floats
• Apple cider

Encouraging your child to stay with alternative, braces-friendly treats may prevent her from trying to eat candies that could break or damage braces. Halloween can still be fun, especially if your youngster (or you) don’t have to visit our Andover office get braces fixed.

Make sure to remind your child to avoid harmful candies, and encourage him to exchange treats with friends to make it more fun. Only passing out candies that children can eat safely, such as soft chocolates, can make them feel included.

Dr. Kathleen Chan and Dr. Ivy Chen and our team hope you enjoy your Halloween season, regardless of whether you are wearing braces.
