Why Do I Need a Retainer?

August 21st, 2025

Congratulations! You’ve done the hard work necessary to create your beautiful smile! You’ve carefully completed all the steps needed to reach the end of your orthodontic journey. Well, nearly all the steps. We can’t forget that last step which will ensure that all your hard work is rewarded.

When you first began orthodontic treatment, Dr. Iwei Huang decided on the best plan for straightening your teeth and perfecting your bite, whether you wore traditional braces, lingual braces, aligners, or other orthodontic appliances. And now that you’re finishing treatment, there’s one more option to consider—your retainer.

Why do I need a retainer?

While you’ve spent time in treatment, more has changed than just the position of your teeth. The periodontal ligament, the connective tissue that connects the teeth to the jawbone, is stretched as the teeth shift. The bone in your jaw changes, too, reforming and rebuilding around the roots of your teeth as they move to their ideal locations.

These changes happen because your braces or aligners apply gentle, constant pressure to move your teeth. When you’ve finished wearing these appliances, the pressure stops. Ligaments will try to return to their original shape, which can shift teeth back toward their old positions. And the rebuilding bone isn’t dense enough yet to stop teeth from shifting due to the normal, everyday pressures of eating, chewing, and smiling.

A retainer prevents your teeth from moving back, or “relapsing,” by giving your bones and ligaments time to stabilize and rebuild. The process takes months, so keeping your teeth in place as bones rebuild and grow denser is crucial. This is especially important for patients with more serious misalignments. Dr. Iwei Huang will let you know which kind of retainer will be best for you and just how long you’ll need to wear your retainer.

Are there different kinds of retainers?

There are! Retainers can be removable or fixed, visible or nearly invisible, metal, plastic, or metal and plastic. Three of the most popular retainer options include:

  • Hawley Retainers—the traditional removable retainer, which uses a molded acrylic plate with wires attached to keep your teeth properly aligned and to hold your retainer in place.
  • Clear Plastic Retainers—a removable retainer made of custom vacuum-formed plastic, which fits over the teeth like a clear aligner.
  • Fixed Retainers—a small single wire bonded to the back of specific teeth, which holds them in place and prevents any movement.

Dr. Iwei Huang will let you know whether a removable or fixed retainer is best for making sure your teeth don’t start to relapse, and fill you in on the benefits and care of each type of retainer.

How long do I need to wear a retainer?

There’s no standard answer to this question. Just like your retainer is custom-built to fit your individual teeth, the amount of time you’ll spend in that retainer depends on your individual needs. Retainers might be worn fulltime for months or years, be worn only at night after several months of daily wear, or be worn long-term to make sure your orthodontic work lasts.

Because you’ve done the hard work already, and your beautiful, healthy smile is the result. Talk to a member of our Chicago team about which retainer option will be best for making sure that this smile lasts a lifetime.

Before You Pop the Top on That Energy Drink . . .

August 14th, 2025

We get it. You’re working out and could use a boost. It’s 2 a.m. and that essay won’t write itself (darn it). You’re in the middle of a rehearsal that goes on and on and . . . 

It’s easy to reach for an energy drink when you’re feeling a bit low on, well, energy. These drinks are loaded with caffeine, and, like coffee or tea, can help you feel more alert. But before you pop that top, let’s look at how energy drinks affect your dental health.

  • Energy drinks are very acidic.

Acid levels are measured using the pH scale, which ranges from 0 (most acidic) to 14 (most alkaline). Saliva has a normal pH somewhere between 6.2 and 7.6, which helps neutralize any acidic conditions in the mouth and promotes a healthy oral environment. But saliva’s neutralizing effect can be overwhelmed by highly acidic foods and drinks.

Why are higher levels of acids bad for our teeth? Acids strip away minerals like calcium from tooth enamel, minerals which make enamel the strongest substance in the body. This demineralization weakens the enamel’s protective outer structure and can lead to enamel loss, sensitivity, tooth discoloration, and decay.

Many energy drinks are among the most acidic beverages on the market. Mineral loss in your enamel starts to occur when the pH balance in the mouth falls to 5.5 or less. Lemon juice has a pH between 2 and 3. White vinegar has a pH of 2.5. Energy drinks can range from 1.5 to 3.5 on the pH scale! Studies show that regular consumption of energy drinks greatly increases the risk and severity of dental erosion.

  • Most energy drinks are full of sugar.

Sugar is easily metabolized, or broken down, by the body. When our bodies break down food, energy is released. That’s why companies add sugar as well as caffeine to their energy drinks. 

The plaque bacteria which create cavities also use sugars in these drinks as an energy source, converting sugars into acids. Just like acidic foods and drinks, bacterial acids break down the mineral structure in tooth enamel. You might notice small white spots when the enamel starts to erode—and a cavity starts to develop. 

  • Energy drinks aren’t just bad for your dental health. 

The temporary burst of energy you get from all the sugar in energy drinks is followed by a sugar crash when blood sugar levels go down again, and you can feel tired, weak, or shaky. 

Even worse, one energy drink might contain three to four times the amount of caffeine found in a cup of coffee. Excess caffeine interferes with healthy sleep. It can cause changes in heart rate, blood pressure, and anxiety levels. 

Children and teens are especially vulnerable to the effects of large amounts of caffeine while their brains and bodies are still developing. That’s why the American Academy of Pediatrics recommend no energy drinks at all for children and teenagers. The FDA suggests that adults should not take in more than 400 milligrams per day of caffeine, while energy drinks can range from around 80 to 400 mg per can. 

If you do have the occasional energy drink, what’s the best way to protect your teeth and gums?

  • Don’t linger over your drink. Sipping slowly over time just bathes your teeth and gums in sugar and acids over a longer period. 
  • Drink water when you’re done. Water helps wash away sugars and acids, hydrates, and promotes healthy saliva production.
  • If the team at Gold Coast Orthodontics gives gum a thumbs up, chew a piece of sugarless gum after downing an energy drink to increase saliva flow and help neutralize acids in the mouth. 
  • Wait at least 30-60 minutes to brush after finishing an energy drink. Acids in the drink weaken enamel, and brushing immediately can be abrasive to the tooth surface.
  • Eat a healthy diet rich in proteins, complex carbs, vitamins, and minerals to feel more energetic.
  • Keep up with good dental hygiene. Brush twice each day for two minutes and floss daily, or more often as recommended by Dr. Iwei Huang.

If you notice signs of enamel erosion—sensitivity, front teeth which are becoming transparent or rough around the edges, yellowish discoloration, or white or brown spots on your enamel—it’s time for a talk with your dentist. When caught early enough, treatment is available which can stop further erosion from harming your teeth.

It can be harder to brush and floss as effectively when you wear braces, so it’s more important than ever to make healthy choices in your diet and to keep up with your dental hygiene. The team at Gold Coast Orthodontics in Chicago is always happy to give hygiene tips! Talk to your dentist or doctor to discover healthy ways to stay focused and energetic. Your workout, your essay, your rehearsal, and, above all, your healthy body and healthy smile will thank you!

What to Do When the Tooth Fairy Isn’t on Schedule

August 7th, 2025

August 22 is National Tooth Fairy Day! If the Tooth Fairy is a treasured part of your child’s life, you’re just in time to celebrate! But what to do when the Tooth Fairy doesn’t arrive on schedule—when baby teeth stay longer than expected or are lost too soon? 

A baby’s 20 baby teeth tend to come in within a fairly predictable time frame. The bottom central incisors in the very front of your baby’s mouth typically make their appearance first, when your baby is around six to ten months old. Over the next few years, the remaining incisors, canines, and first molars arrive. Last on the scene are the second molars, which usually show up between the ages of 23-33 months. 

Just as baby teeth follow a pattern coming in, they tend to follow the same pattern falling out. The front teeth begin to wiggle and loosen around age six or seven, while the last of the baby teeth, the canines and second molars, are often lost between the ages of ten and 12. 

Baby teeth fall out as the adult teeth below them push up as they erupt. The top of the new tooth puts pressure on the root of the baby tooth, gradually dissolving it. As the root grows smaller and can’t anchor the tooth, the tooth begins to wiggle and eventually becomes loose enough to fall out. This leaves the adult tooth perfectly placed to grow into its proper position.

Sometimes, though, teeth linger far past their fall-out date. Sometimes, because of decay or trauma, they are lost much too early. In either case, Dr. Iwei Huang can provide treatment to protect little smiles now and to ensure that there’s space for the permanent teeth to erupt and align correctly.

Teeth Which Overstay Their Welcome

If that baby tooth never gets wiggly, the team at Gold Coast Orthodontics can help! When baby teeth stubbornly hang on, adult teeth can erupt behind them, creating a double row of teeth commonly known as “shark teeth.” These permanent teeth can become crowded or misaligned as they try to fit in any space available. Or a baby tooth can block an adult tooth from erupting at all. When that baby tooth just isn’t budging, an extraction will create space for the permanent tooth to erupt.

Extracting a baby tooth is generally a straightforward procedure because primary teeth have very small roots. Your child’s dental team at Gold Coast Orthodontics are experts in helping you prepare your child for the procedure in a gentle, reassuring, and age-appropriate way. 

Often, a local anesthetic is all that’s necessary for a simple extraction, but if you feel sedation would better fit your child’s needs, discuss sedation options with your dentist. After the extraction, you’ll be given clear information on how to deal with pain and swelling, which foods and drinks are best while the extraction site heals, and how to protect the area.

Teeth Which Exit Too Early

In the case of decay or trauma, your child’s dentist will do everything possible to save the tooth. When decay is so extensive that there’s not enough structure left to hold a filling or crown, or when there’s an infection in or around the tooth, or when an accident or injury has caused serious damage, extraction might be the healthiest option. Depending on your child’s age, further treatment might be needed afterward to protect future smiles. 

Besides their roles in eating and speaking, baby teeth save space for permanent teeth. If remaining baby teeth shift, taking up part of the empty space left behind by the lost tooth, the adult teeth below won’t have the space they need to align properly as they arrive. Permanent teeth could come in at an awkward angle or erupt in the wrong spot. 

To prevent these problems, your dentist might recommend that your child visit an orthodontist for a space maintainer. Space maintainers are small, custom-designed appliances which keep the remaining baby teeth in place. This prevents neighboring teeth from shifting to fill the empty spot and ensures that there’s enough room for the adult tooth to arrive right on schedule and right where it belongs. 

It’s comforting to have charts which let us know when little teeth will typically come in and when they will typically fall out. But unexpected events might mean teeth overstay their welcome or depart too soon. When the Tooth Fairy can’t keep to her schedule, schedule an appointment at Gold Coast Orthodontics in Chicago as soon as possible to make sure your child is on track for a future of healthy smiles.

Why Do I Need Rubber Bands?

July 31st, 2025

Getting braces is a huge step in creating the beautiful smile you want. It’s easy to see how important your wires and brackets are. Week by week, you and your family and friends can see the progress you’re making as your teeth become straighter. That makes all the careful brushing, periodic adjustments at our Chicago office, and annoying loose ligatures worthwhile.

And while straight, even teeth are the visible reward you get for your months in braces, there’s a benefit that’s every bit as important that might go unnoticed by your friends and family—a healthy, properly aligned bite.

Many people have some kind of malocclusion, or bad bite. There are several different bite problems we treat. Some of the most common are:

  • Overjet (the upper front teeth protrude too far forward over the bottom teeth)
  • Underbite (the bottom teeth overlap the top teeth)
  • Crossbite (one or more teeth haven’t come in in the proper position, often with an upper tooth fitting inside a lower tooth)
  • Open bite (the upper and lower front teeth don’t touch).

When the jaws and teeth don’t fit together properly, you might be looking at damaged teeth, headaches, and painful problems with the temporomandibular joint, or jaw joint, in your future. That’s why correcting your bite early is so important. Using rubber bands with your braces is one of the most popular and effective ways to help create a better bite.

Bands are used with your braces to gradually move your teeth into their best position. Specially designed brackets with tiny hooks are bonded to very specific teeth. Why so specific? Because the placement of the brackets depends on which type of malocclusion we are correcting. Rubber bands are then attached to the bracket hooks, usually from an upper tooth to a lower one. When they are in just the right position, those little bands provide just enough force to move your teeth more quickly and effectively than braces alone can.

If you need bands to help correct any kind of malocclusion, you will play a very important part in your orthodontic treatment. It will be your job to attach your bands every day. Don’t worry—while it can seem confusing at first, we’ll make sure you know exactly how and where to place them.

How long should they stay in? You’ll probably need to wear your bands 24 hours a day. It’s while you’re moving your mouth and jaw muscles that your bands are working their hardest. Talk to us about removing them for brushing and flossing, and whether you should wear them while you eat.

Can you use the same bands over several days? Not a good idea. Bands are selected for size and strength to move your teeth very precisely from visit to visit. When bands stay on too long, they become too stretched out to supply the proper pressure needed to move your teeth efficiently. Dr. Iwei Huang will let you know how long is too long for your specific bands.

Are two bands better than one? Absolutely not. Again, the bands you’re given at each visit are designed for your specific needs. Too much pressure can actually be harmful. Just keep to your recommended schedule of replacing bands, and your orthodontic treatment will stay right on track.

Attaching rubber bands? Keeping them on all during the day? Replacing them as needed? All of these responsibilities might seem a bit overwhelming at first, but we are here to give you all the information and support you need to succeed. Because straight, even teeth and a bite that is healthy and functional? That’s truly how you create your beautiful smile!
