St. Patrick's Day: Celtic pride, green shamrocks, and lucky charms!

March 11th, 2026

“St. Patrick's Day is an enchanted time -- a day to begin transforming winter's dreams into summer's magic.” Adrienne Cook

Lucky green shamrocks, leprechauns, and pots of gold – it must be St. Patrick’s Day! If you’re not Irish, how do you go about celebrating St. Patrick’s Day? It’s easy: You just put on one of those tall leprechauns hats, dress in green from head to toe, and wear one of those carefree pins that say “Kiss Me, I’m Irish”. On St. Patrick’s Day, everyone is Irish, and that is the universal beauty of the holiday. Celtic pride does not discriminate.

Wondering what our team at Teguis Orthodontics is doing to celebrate March 17th? Well, we’ve thought about doing everything from handing out lucky gold coins (you know, the fake ones that are made of chocolate) to shamrock stickers. Maybe we’ll even give away green toothbrushes and floss! You’ll never know unless you come in to see Dr. Teguis !

All kidding aside, St. Patrick’s Day is an important cultural and religious holiday. There are lavish parades and church services across Ireland on March 17th. Over time, however, the holiday has developed into a day to observe Irish culture in general. In places like England and the United States, where there is a large Irish Diaspora, the holiday has greater significance than other countries. From the streets of Boston to St. Patrick’s Cathedral in New York, it is a day of celebration, and many Americans of Irish descent will cook up a traditional meal of corned beef and cabbage.

So, to all of you with Irish ancestry, and to all of you who have decided to be Irish for the day, our office wishes you a Happy St. Patrick’s Day. Good luck looking for a pot of leprechaun gold, which is said to exist at the end of the rainbow. However, keep away from those sugary Lucky Charms; sweet cereals might taste good, but your kids’ teeth might not be feeling too lucky if they eat it for breakfast every day. Have a great St. Paddy’s Day!

What’s on Your Orthodontic Calendar?

March 4th, 2026

Did you know that there’s a World Orthodontic Health Day in May? Or that National Orthodontic Health Month takes place in October? You may not have circled these days on the calendar—in fact, this might be the first time you’ve heard about them! But celebrating these special days is just one way that orthodontists share the health benefits of orthodontic treatment with us.

That’s because orthodontic treatment is about more than creating a beautiful smile. With the help of Dr. Teguis, you might also be creating:

  • Healthier Teeth and Gums

When your teeth are aligned, it’s easier to prevent tooth decay and gum disease. Crowded, crooked, or overlapping teeth make it harder to brush and floss as effectively. Plaque that builds up in those hard-to-reach places on the tooth enamel helps create cavities. And over time, built-up plaque turns into tartar, a leading cause of receding gums and gum disease. Straight, properly spaced teeth make efficient brushing and flossing a breeze!

  • A Comfortable, Functional Bite

A malocclusion, or bad bite, occurs when the teeth and jaws don’t align properly. In a healthy bite, teeth aren’t crowded, twisted, or spaced too widely apart. The top teeth should slightly overlap the lower teeth. And the ridges of your upper molars should fit smoothly with the grooves of the lower molars.

If your bite is off, you’ve probably noticed chewing pain, headaches, or jaw pain. Over time, malocclusions can lead to worn enamel, cracked teeth, and tooth grinding, and have been linked to mouth breathing, which dries out the mouth and isn’t good for your dental health. Braces or aligners, with other appliances if needed, can not only correct a malocclusion, but prevent the very uncomfortable side effects of a bad bite.

  • Improved Facial Symmetry

Malocclusions affect facial symmetry. Underbites occur when the lower jaw is too large, while small lower jaws can cause serious overbites. Bite problems can mean overjets (also called “buck teeth”), or open bites (where the front teeth don’t touch when the mouth is closed). Crossbites result in one or more upper teeth fitting inside the lower teeth. These conditions can affect both facial balance and profile.

With the use of braces and appliances like palatal expanders, Herbst® appliances, or headgear, Dr. Teguis can guide jawbone development while a child’s bones are still growing. For older patients, we can design a treatment plan to align teeth, correct malocclusion, and improve facial symmetry.

  • Psychological Benefits

We can’t forget the invisible benefit of orthodontic treatment: a happy, comfortable smile is a great confidence-booster! If you’re reluctant to share your smile with the world, a visit to Dr. Teguis can let you know just what to expect from treatment, and just how it can improve your life.

Because it’s so important to both our dental health and our overall well-being, we’re happy to celebrate orthodontic health on special days throughout the year. And let’s also celebrate the fact that there’s no calendar deadline when it comes to scheduling a healthier smile! Whether it’s early treatment for younger children to guide jaw growth, or the common orthodontic treatment window during the teen years, or adult treatment to create the smile you’ve always wanted, help is available at our Biddeford office whenever you’re ready to set the date!

Generic Clear Aligners vs. Invisalign®

February 25th, 2026

You may have a talent for home repairs. You may be able to rebuild your computer. You may even be able to put together a whole room of furniture armed only with flat-box kits and an Allen wrench. But, please—don’t try do-it-yourself orthodontics!

Now that generic clear aligners are available, you might consider giving them a try to save some money. But is straightening your own teeth really a good idea? Before you are tempted, let’s look more closely at the products and the dental science involved.

Invisalign®

  • Invisalign clear aligners are used by orthodontists and dentists with experience in custom treatment for your smile. A 3D image of your teeth will be captured by the iTero Element® scanner. Using special software, your doctor can map out each projected shift in your teeth, and even show you a projection of your finished smile!
  • Your Invisalign aligners will be tailored to fit your teeth precisely using the 3D scan and 3D printing. They are made from SmartTrack® material, a product specifically engineered for a perfect, comfortable fit. Invisalign aligners are even trimmed to fit your individual gumline to prevent irritation.
  • When your first sets of Invisalign aligners arrive at our Biddeford office, Dr. Teguis will check for fit, answer any questions you might have about use and care, and let you know what to look for and what to expect. Your progress will be monitored with visits every six to eight weeks. (And for parents of teens, Invisalign aligners can offer blue “compliance indicators” to let you know they are being worn the 20-22 hours a day necessary for the best and fastest results.)

Generic Aligners

  • You might be required to make a putty mold of your own upper and lower teeth, which is not the easiest thing to do well, and to take selfies of your teeth.
  • The aligners will be sent to you in the mail. They are generally made of hard plastic with generic gumlines. There will be no one to tell you if the aligners fit properly.
  • They are sometimes less expensive because there is no in-person medical supervision. A dental professional working for the company will look at the model created from molds you submit, and recommend a series of aligners to correct the problems he detects by looking at the model and your selfies. This supervisor will not be able to assess the overall dental health of each patient to make sure teeth and gums are healthy and ready to start treatment, and will not be able to tell if the teeth are moving properly or improperly once the aligners are in use.

Finally, while generic aligners may potentially have some success in minor tooth straightening, they are not created to deal with complex bite issues or malocclusions.  In fact, using generic aligners with no supervision can cause more serious dental problems than a patient started with.

Sure, sometimes a do-it-yourself project turns out well. But your teeth and bones are too important for home improvement. When it comes to creating a beautiful, even smile and balanced, comfortable bite while making sure of your dental health, it’s always best to trust a professional like Dr. Teguis to provide you with gentle, tested, and successful care!

Five “Don’ts” When You Wear Aligners

February 18th, 2026

Choosing clear aligners was a great decision on your part! Straight teeth and a healthy bite? Subtle, almost invisible aligners? 3D technology custom-designed just for you? All the positives we’ve come to expect from your choice of orthodontic treatment.

So, don’t sabotage your good work! Here are five negative habits that will prevent you from getting the most out of your aligners:

  1. Don’t forget to keep them clean

One of the reasons you chose clear aligners is because they are nearly invisible. But careless cleaning habits can leave them discolored, scratched, or cloudy. Soaking in colored mouthwash can stain aligners. Using abrasive cleaning products or brushing with a heavy hand can cause scratches. And failing to keep aligners clean can lead to a buildup of cloudy plaque. Talk to us! We know all the best products and practices to keep your aligners their most sanitary—and most invisible.

  1. Don’t eat with your aligners in place

Aligners are simply not meant to be used while you eat. Chewing puts too much stress and pressure on them, and can lead to aligner damage and even breakage. Because you will be wearing your aligners for most of the day, planning ahead for your meals is key. One bonus: it’s a great way to eliminate unconscious snacking.

  1. Don’t let foods or drinks stain your aligners

It’s great that you take your aligners out to eat, but do you remember to brush before you replace them? Foods like spaghetti sauce and blueberries that stick to your enamel can stain your aligners. And it’s always best to remove your aligners before drinking a beverage. If a drink can stain your teeth, it can stain your aligners. Red wines, dark juices, colas, and, of course, coffee and tea can cause discoloration. Another thing to consider? Food particles in the trays can not only stain your aligners (and your enamel), but keep your teeth in contact with the acids and sugars that lead to cavities.

  1. Don’t run hot

Aligners are formed using heat, so it makes sense that heat can de-form them as well. Drinking hot beverages with your aligners in place can change their shape—and even subtle changes will affect your progress. Since warped aligners might have to be replaced, save the piping hot beverages for those times you’re not wearing aligners. It’s best not to clean them with very hot water as well.

  1. Don’t forget to wear them

Aligners need to be worn approximately 20-22 hours each day. If you’re not putting in the required time, you’re delaying your progress. If you’re having trouble with scheduling meals or activities, talk to Dr. Teguis when you visit our Biddeford office. We have suggestions.

But let’s not just dwell on the negatives. We like to focus on the positive, too, so here’s the one item on your “Do List” that will absolutely make your aligner experience the best it can be:

Do follow our recommendations!

Clean your aligners with the proper tools and products—and clean your teeth and aligners after every meal and snack. Remember that water is the only guaranteed problem-free beverage. Don’t expose aligners to heat or eat with them in place, because they can be warped or damaged. And be sure to wear them as long as you need to each day—this will keep your treatment on track and on schedule.

Enjoying a future filled with beautiful, healthy smiles? That’s not just a positive—it’s a happily-ever-after!
