The Twin Block Appliance

May 28th, 2025

Orthodontic treatment involves a lot more than just straightening your teeth. For a healthy smile, your bite must be healthy as well! This means that the upper and lower jaws need to fit together properly and comfortably.

If your bite is out of alignment because of jaw misalignment, orthodontic treatment can help correct the shape and position of your jaws with devices called functional appliances. These appliances are most often used for young patients whose bones are still growing, and are designed to treat malocclusions, or bite problems.

Common malocclusions such as overbites and overjets can occur when the upper teeth protrude further than they should, or the lower jaw is positioned too far back, or both. The Twin Block appliance can be used in such cases to help move your lower jaw and teeth into alignment with your upper jaw.

Why “Twin”? Because the Twin Block appliance is two separate pieces, each made of wire and smooth acrylic. Both pieces are crafted to fit precisely over your upper and lower arches and can be adjusted as your treatment progresses. The top plate can also be adjusted, if necessary, to widen the upper palate.

Why “Block”? Acrylic blocks cover the biting surfaces of several of your upper and lower teeth. These blocks fit together like a 3D puzzle. When you bite down, the upper blocks interlock with the lower blocks, pushing the lower blocks forward just a bit before you can bite down completely. Over time, bit by bit (and bite by bite), the Twin Block appliance advances your lower jaw and teeth to create a balanced, comfortable bite.

For the quickest and best results, you should wear your Twin Block appliance as directed. It’s made to be worn comfortably while you sleep, eat, and otherwise go about your day. (It’s a good idea to check with our Philadelphia, PA orthodontic team to see about removing it when you’re active, especially for swimming and contact sports.) When it’s time to brush, the Twin Block appliance is removable. This means that you can clean your teeth and your appliance easily.

And, while it’s made to work hard for you, it’s not indestructible. Don’t expose your appliance to heat or hot water, as the plastic may warp. Use the cleaning methods we recommend. Finally, when your appliance is out of your mouth, keep it in its case! You don’t want your appliance to end up carefully wrapped in a napkin in the nearby recycling bin. Or, even worse, in your dog’s mouth instead of yours.

The Twin Block appliance might fit together like a puzzle, but there’s nothing puzzling about how to achieve your best and fastest results. Your success really depends on you. Follow Dr. Joseph Brogan and our team’s advice, wear your appliance as directed, and you’ll be on your way to a healthy, comfortable bite and an attractive, confident smile!

Memorial Day and Getting Ready for Summer

May 24th, 2025

Memorial Day didn't become an official holiday until 1971, but Americans started gathering annually in the spring to remember those who lost their lives in war during the 1860s, right after the Civil War. Celebrated on the last Monday in May, people still decorate the grave sites of war veterans and hold memorial services, but Memorial Day has also evolved into a day that signifies the beginning of summer.

During the summer months, many people take road trips to visit family members. Some head off to the airport to enjoy a long-awaited vacation far away, while others look forward to spending time with friends and family at home. However you spend Memorial Day and the subsequent summer months, there are a few things you can take care of to ensure your summertime is enjoyable.

Checklist for an Enjoyable Summer

  • Have the AC Checked. During the hottest days of summer, many families find themselves sweating it out due to a broken air conditioning system. Be proactive so you can avoid waiting for hours or days because the HVAC repair person is booked solid. Have your air conditioning system checked before or around Memorial Day each year.
  • Ensure Security While You're Away. When you leave for vacation, the last thing you should have to worry about is the security of your home. Install a home security system, if possible, and put a timer on your lights so they go on and off at normal hours. You can also alert your local police department that you'll be gone, and ask them to drive by your house once in a while to make sure everything is okay.
  • Visit Dr. Joseph Brogan Before Vacation. Many people put off exams until after summer vacation. Avoid the crowds and make sure your physical and oral health are in top shape prior to vacation time so there are no unpleasant surprises.

Our team at Brogan Orthodontics wants you to look forward to Memorial Day and the days of summer by preparing to spend the time safely and comfortably. As you plan ahead, take care of your health and secure your home, you can place your focus on creating memories with family members and friends while enjoying your favorite Memorial Day traditions.

Just Add Water

May 23rd, 2025

One of the many benefits of your clear aligners is that you can remove them to eat. You should brush after every meal, just like you would with traditional braces, but cleaning your teeth is much easier without having to work around and between brackets and wires.

But when you wear your aligners 22 hours a day, you might be tempted to leave them in when you’re just having a sip of something when you’re thirsty. Unless you’re drinking water, please don’t.

What’s the problem with a can of cola or a cup of coffee?

  • Staining

The virtue of your clear aligners is that they are, well, clear! Probably one of the reasons you decided on this method of treatment was because you liked the idea of an inconspicuous appliance.  Unfortunately, dark beverages such as colas, coffee, tea, and red wine can stain your aligner, making it more visible.

  • Warping

Very hot beverages might actually affect the shape of your aligners. Since they are formed using heat, it makes sense that heat can also de-form them. If hot teas and coffee drinks cause a change in the shape of your aligners, they will not move your teeth the way they were meant to.

  • Affecting Tooth Health

Even though our enamel is very strong, sugary and acidic drinks can damage it. Acidic foods can erode enamel, and the sugars in our diet provide food for cavity-causing bacteria, which then produce acids that erode enamel.

Normally, saliva provides some protection from acids and sugars by diluting them and washing them away from the teeth. When you drink a cola or an orange juice with your aligners on, some of the liquid will get in them, and can stay in them until the aligners are removed. You will actually give these problem beverages the opportunity to bathe your teeth in sugar and acid over a longer period of time, without exposure to saliva to help offset potential harm. And after all your work to create a beautiful smile, you certainly don’t want new cavities!

How to protect your aligners and keep them their cleanest—and most invisible?

  • Take your aligners out before drinking beverages that can stain them, or, if you can’t, try using a straw. Clean your aligners according to Dr. Joseph Brogan and our team’s instructions to keep them as clear as possible.
  • Don’t drink very hot beverages with your aligners in place. Try icing your coffee and tea if you can’t remove your aligners. And if you think your aligners have changed shape, please give us a call.
  • Drink water! Water hydrates you, doesn’t damage enamel, and keeps your aligners clean. Tap water is your best option, as even bottled waters can be acidic.

If your aligners should become stained, remember that you change them frequently, so the staining can be a temporary problem. If you do have a drink of something hot and your aligners feel “off,” give our Philadelphia, PA office a call. We’ll let you know if you need to replace them.

But prevention is always best! Avoid staining from the start by removing your aligners before you drink dark beverages. Don’t expose your aligners to heat. Think about replacing unhealthy drinks with water. And certainly brush right away, or rinse with water if that’s not possible, if you drink a sugary or acidic beverage. These simple precautions will help keep your aligners, and, most important, your teeth, looking their best.
