Earth Day

April 22nd, 2026

The idea for Earth Day was the brainchild of Gaylord Nelson, a senator from Wisconsin. He envisioned an Earth Day that would be a kind of environmental teach-in. The first Earth Day celebration took place on April 22, 1970, and a surprising 20 million people participated on that day. Ultimately, it became the largest organized celebration in US history.

Earth Day Over the Years

Over the years, the recognition of the day, and the number of people celebrating it all over the world, turned Earth Day into an international celebration. Because it is celebrated throughout the world, it is not only the largest international environmental observation, but it is also more widely celebrated than any other environmental event in the world. Today, Earth Day is celebrated in 175 countries where over 500 million people participate in celebrations.

The Earth Day Movement

The Earth Day movement is credited with developing the idea that people should “think green”. It encouraged congress to enact laws, including one that resulted in the creation of the Environmental Protection Agency. It also inspired the passage of the Endangered Species Act.

The Five R's and Their Importance

  • Reduce – Reduce by avoiding unnecessary purchases. Reduce your use of materials that wind up in landfills. Reduce the use of chemicals around your house. Reduce your use of disposable bags, plates, cups, eating utensils, and batteries.
  • Reuse – Instead of using plastic bags for your groceries or purchases, bring your own reusable bags. When you go to buy coffee at Starbucks, take a travel mug so you don't have to get your coffee in a disposable paper cup. Instead of storing food in disposable refrigerator containers, buy containers that can be washed and reused. Don't use regular batteries. Whenever possible, opt for rechargeable batteries that you can reuse.
  • Recycle – Most cities offer a recycling program to collect used bottles, cans, and newspapers. Recycling includes collecting recyclable materials that would otherwise be considered waste, sorting and processing recyclables into raw materials such as fibers and manufacturing raw materials into new products.
  • Re-buy – Make an effort to purchase things that are made through recycling. When purchasing furniture, look for items that are made from reclaimed wood. When buying paper for kids school work, computer printer paper, holiday cards, or anything else, make a point of purchasing recycled paper products. Instead of buying clothing at full retail price, shop for second hand clothing. You will save a lot of money by doing so!
  • Rethink – Rethink the way you do things so that you do them in an eco-conscious way at all times. Instead of driving to work alone, consider taking the bus or going in a carpool. Walk or ride your bike when you're only going a short distance. Plan your shopping trips and errand runs so that you can do everything on one day, and do it in a way where you can save time and gas.

Other ways to "think green" include growing your own food, composting yard waste and food scraps, or by participating in local recycling programs. Join a group like Freecycle so you can share your unneeded and unwanted possessions with people who can use them. Likewise, you'll be able to get things you need or want for free.

Earth Day teaches people that the planet belongs to everyone, so everyone is equally responsible for protecting it. Although Earth Day is an environmental celebration, our team at Teguis Orthodontics wants to remind you that you don't have to wait until then to make changes that will allow you and your family to live a greener life.

Happy Earth Day from the team at Teguis Orthodontics.

Caring for Your Smile While Wearing Invisalign®

April 15th, 2026

Getting your braces off is exciting. You’ve been working on your new smile for months or years, and it’s time for the trips to our Biddeford office to pay off. Can you imagine how bad it would be to discover that your teeth are straight, but that there’s decay?

Caring for your smile while wearing Invisalign goes beyond just waiting for your teeth to get straighter. It involves cleaning your teeth regularly and thoroughly to prevent tooth decay. That way, your smile will be more beautiful than ever when you’re done with your Invisalign treatment.

Take Your Trays Out

The first difference you may notice between Invisalign and traditional metal braces is that Invisalign aligners are invisible, but there’s another important distinction as well. Invisalign braces are removable. You can take the trays out, and you should. Remove the trays while you’re eating so you don’t get food stuck in them. Also, remove them while you’re cleaning your teeth so that you can have full access to all the nooks and crannies in your mouth.

Brush Normally

The guidelines for brushing your teeth with Invisalign don’t change compared to braces. Brush your teeth at least twice a day using a soft toothbrush and a fluoride toothpaste, being sure to get all surfaces of your teeth. If possible, brush after each meal.

If you can’t, be sure to drink some water and swish it around in your mouth when you’re done eating to get rid of the extra food on your teeth. Leaving carbohydrates, such as sugar and starch, on your teeth opens the door to tooth decay.

Floss and Wash

Flossing your teeth gets out the bits and pieces stuck between them. It’s a time-consuming task when you need to navigate the wires of traditional metal braces, but thanks to Invisalign’s removable design, flossing is no problem. Rinsing your mouth with a fluoride antibacterial mouthwash also helps clean your teeth because it gets into all of the spaces. Floss and rinse one or two times daily.

Cleaning Your Trays

Cleaning your Invisalign trays keeps them from getting riddled with bacteria, and it helps keep your teeth free from excess food. You can use the Invisalign cleaning system, which involves placing the trays in a tub with cleaning crystals. The plastic trays are clean after 15 minutes. You can also ask Dr. Teguis for other ways to clean your trays.

Courting Disaster

April 8th, 2026

When we think of sports and dental damage, we naturally think of hockey and football. But when it comes to the actual number of dental injuries suffered each year, vying for top seed is the game of basketball.

How is this possible? After all, football and hockey are categorized as “collision sports”! But along with the helmets, shin guards, and padding, these teams quite often require mouthguards—and this makes all the difference. Studies have shown that an increase in the number of players wearing mouthguards means a decrease in the number of oral traumas.

And while basketball isn’t considered a collision sport, it is a contact sport. Basketball is a combination of running, jumping, hard surfaces, and solid bodies. And elbows. We can’t forget elbows. So a broken or even a knocked out tooth isn’t, unfortunately, all that unusual when bodies in motion meet hard surfaces—or other players. But there are other dental dangers as well. Besides tooth injuries, oral injuries can involve:

  • The ligaments and bone structures holding teeth in place
  • Bones in the upper and lower jaw
  • Delicate gum, tongue, and mouth tissue.

You need a solid defensive strategy to reduce the severity of oral injuries or to prevent them from happening altogether, especially when you wear braces. The best play in your playbook? Wearing a mouthguard!

Choosing the right guard is key. There are three common options, and you can choose the model which works best for you:

  • Stock guards, which are ready-made guards in pre-formed shapes and sizes. You can buy them over the counter in drug stores and sporting goods stores. Because these guards aren’t shaped to fit your teeth and mouth specifically, they can be less protective (and harder to speak around).
  • “Boil-and-bite” guards can also be purchased, and can provide a closer fit. After warming the guard in hot water as directed, you place it in your mouth and bite down firmly to mold it to your teeth.
  • Dr. Teguis can make you a mouthguard that is designed and crafted specifically for your use. Because this guard is custom-fitted, it provides better protection for your teeth and mouth. Patients often find custom guards much more comfortable and more durable as well.

Mouthguards are most effective when you wear them on the court and care for them off the court. This means avoiding a few flagrant fouls.

  • Dirty play

All those moist nooks and crannies inside your mouthguard are a perfect environment for bacteria, mold, and plaque buildup. You should clean your mouthguard carefully every time you wear it, and let it air dry before popping it back in the case. Ask Dr. Teguis for advice on getting your guard and its case their cleanest.

  • Failure to sub out in a timely fashion

Mouthguards don’t work if they’re damaged. If you notice any warping, breakage, or jagged or sharp edges, contact our Biddeford office for a replacement. If a guard doesn’t fit you properly, it doesn’t protect you, and sharp edges can irritate or injure delicate mouth tissue.

  • Unnecessary roughness

Your mouthguard protects you, so don’t forget to protect it! Keep your guard in its case when you’re not wearing it to save it from dirt, damage, and disappearance.

If you know your basketball, you know your guard game can make all the difference. Even though a mouthguard might not be mandatory on your team, that doesn’t mean it’s not essential. Remember that basketball is a contact sport, and protect your teeth, your mouth, and your braces with a mouthguard whenever you play.

April is National Facial Protection Month

April 1st, 2026

The Importance of Facial Protection

Americans from all walks of life should mark April as National Facial Protection Month on their calendars. The American Association of Pediatric Dentistry, Academy for Sports Dentistry, American Academy of Pediatric Dentistry, and American Association of Oral and Maxillofacial Surgeons have combined forces to sponsor this annual campaign, which aims to educate and remind us of the importance of protecting our face and teeth against impacts and injuries.

Wearing a helmet can save your life and prevent devastating physical damage in a variety of situations, from playing football to riding a bicycle. According to the American Association of Oral and Maxillofacial Surgeons, helmets reduce the risk of various head injuries by as much as 85 percent. Whether helmet laws apply in your area or not, Dr. Teguis and our team at Teguis Orthodontics want you to make sure you and your loved ones wear helmets with the appropriate safety ratings for specific activities. (A sticker on or inside the helmet will usually indicate this rating.) Helmets can also help save your teeth if they come with an attached faceguard, an essential addition for football players and others involved in contact sports.

Preventing Dental Injuries

A mouthguard can protect you against a variety of dental injuries, such as cracked, broken, or knocked-out teeth. The American Dental Association states that mouthguards play an essential role in preventing up to 200,000 dental injuries each year, and many states mandate their use for sports activities such as football and hockey. The Academy for Sports Dentistry warns, however, that these mouthguards must be custom-fitted as precisely as possible to prove effective. Have a professional-quality mouthguard molded and fitted by our team at Teguis Orthodontics for better protection than a generic store-bought or “boil-and-bite” variety can offer. These cheaper versions tend to wear out quickly, interfere with proper breathing, and provide uneven degrees of cushion against impacts. Always have a fresh mouthguard fitted for each new sports season.

Choose the right combination of helmet, faceguard, and mouthguard to protect your teeth and face this April, and tell your friends to do the same! To learn more about mouthguards, or to schedule an appointment with Dr. Teguis, please give us a call at our convenient Biddeford office!
