How Do I Care For My Pet’s Teeth?

March 25th, 2026

Our pets are a valued part of the family, but dogs and cats are not regularly known for their minty-fresh breath. Did you know that bad breath can be a sign of a more serious dental problem for your furry companion?

If you live with a pet or two, you’ll want to brush up on your animal dental knowledge and make sure everyone’s teeth stay healthy.

Proper dental care is essential to a pet’s overall well-being. About 80 percent of dogs and 70 percent of cats suffer from periodontal disease after the age of three.

Not only is this unhealthy for their mouth, it can lead to more serious health problems, including organ damage and heart failure. Toxins from periodontal disease seep into your pet’s bloodstream and have the potential to cause fatal organ damage.

Your veterinarian will check your pet’s teeth at an annual or six-month examination, but here are a few signs of periodontal disease you should watch for at home:

  • Yellow/brown tartar
  • Foul breath
  • Red, inflamed, or bleeding gums
  • Excessive drooling
  • Pawing at the mouth or rubbing one’s jaw against objects
  • Difficulty chewing

Aside from regular checkups at the vet, the best thing you can do for your pet is brush its teeth daily. Bacteria can recolonize onto the surface of teeth within 24 to 36 hours, so it’s essential to remove plaque before it turns into tartar. Ask your vet for a recommended toothbrush and pet toothpaste.

Dental hygiene chews can also help to reduce the effects of gingivitis, but some chews can actually make your pet’s oral health worse. Treats such as cow hooves, pig’s ears, and animal bones can damage teeth and cause other problems if ingested. Your vet can help you choose items that are healthiest for your pet.

Your dog’s favorite toys may also pose a threat to their oral health. Abrasive toys such as the popular green tennis balls can create wear and tear on the surface of pets’ teeth.

As with your own teeth, your dog or cat’s oral health plays a large role in its overall health. Remember to schedule regular checkups and ask your veterinarian for more tips on how to care for your pet’s teeth most effectively.

Your Five-Step Guide to Preventing Tooth Decay While Wearing Braces

March 18th, 2026

If you’re wearing braces, then you know they are working hard to straighten your teeth. However, those hard-working braces are also preventing you from easily cleaning your teeth. It is essential that you put some extra attention into preventing tooth decay while wearing your braces. When your braces are finally removed by Dr. Iwei Huang, you want a beautiful, white smile, not decayed or stained teeth. Here, we’ve listed the five best ways to ensure you have the smile you’ve always dreamed of once your braces are gone.

Use a Special Toothbrush

A regular toothbrush just doesn’t cut it when you are wearing braces. You also need to use an interdental toothbrush so that you can effectively clean behind the braces. This type of brush has bristles that are shaped like a Christmas tree that can remove food residue in the braces and on the teeth. We also recommend using a WaterPik, with its highly pressurized pulsating water, to help get all of those hard-to-reach places.

Brush after Every Meal

Since braces block food from naturally escaping your teeth after eating, it’s important that you take the time to brush and floss after every meal. The less time food has to sit on your teeth, the less likely it is to cause decay. This may seem like an inconvenience, but trust us, when you get your braces off, you will be very glad you brushed after every meal.

Don't Forget the Mouth Rinse

Even after properly brushing and flossing, there are probably some food particles in your braces. A fluoride mouth rinse is the best way to ensure that every bit of food is removed after meals. If you do not have a mouth rinse available, we suggest using water — it’s better than nothing.

Avoid Sweets

Prevention is definitely the best medicine when it comes to avoiding tooth decay. If you can nix decay-causing sugary foods from the outset, we promise you’ll spend less time trying to treat problems in the future.

Get Regular Checkups

Visit your dentist regularly while you are wearing braces. Our office recommends a thorough cleaning every three to six months. Let our Chicago office know if you have questions about your oral health while in braces - our entire team at Gold Coast Orthodontics is here to make sure your teeth are as beautifully straight as they are healthy!

Interproximal Cavities: The Inside Story

March 12th, 2026

Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth. You want to present a gleaming smile to the world, after all. And you make sure to brush the inside surfaces as well, because who wants to feel a fuzzy patch of plaque every time their tongue hits their teeth? And, naturally, you remember to clean the tops of your molars, because those crevices make them more cavity-prone than any other surface.

Done? Not quite!

You might be surprised to learn that no matter how well you’ve brushed all the visible surfaces of your teeth, you’ve left quite a bit of enamel untouched—the adjoining, or touching, surfaces of the teeth that sit next to each other.

You’ve probably noticed that your bristles can’t . . . quite . . . reach all the enamel between your teeth (especially between your molars!) when you’re brushing. This means that food particles and plaque have an easier time sticking around. And when the bacteria in plaque are left undisturbed, especially with a banquet of food particles available, they produce acids which gradually eat away at the enamel covering our teeth, creating a cavity.

Here’s where we work in some specific dental vocabulary. “Interproximal” means between the adjoining, or touching, surfaces of the teeth. And an interproximal cavity is a cavity that develops on one of those side surfaces of your teeth.

  • Preventing Interproximal Cavities

Fortunately, prevention is about as basic as it can be—brushing and flossing effectively. Dentists recommend brushing for two minutes at least twice a day and flossing once each day. While most of us are good about keeping up with brushing, sometimes that daily flossing is more a goal than a reality.

But it’s flossing which really does the trick when it comes to interproximal cleaning. If you floss correctly, food particles and plaque are removed from between the teeth and around the gum line—places where bristles just can’t reach.

When you wear braces, though, flossing isn’t quite so basic. Getting that floss just where it needs to be in between brackets and wires and in between teeth can be a challenge!

The good news is there are many products designed just to make flossing easier while you’re in orthodontic treatment:

  • Floss threaders are flexible hoops that help you thread floss behind your wires easily.
  • Precut floss strands use a stiff tip at one end for threading floss through wires.
  • Interproximal brushes are tiny, cone-shaped brushes which can fit between your teeth and braces for precise cleaning.
  • Water flossers eliminate floss altogether, using a pulsing stream of water to clean between and around teeth and braces.

During your next visit to our Chicago office, Dr. Iwei Huang can give you tips on how to use any of these tools effectively for cleaner teeth and cleaner braces.

Preventing cavities on the exterior surfaces of your teeth is probably pretty much automatic by now, but don’t forget the potential for stealth decay! If we find signs of erosion on the sides of your teeth, or if your hygienist lets you know that you’ve got a lot of interproximal plaque buildup, work with your dental team to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.

Can Toothpaste Repair Tooth Decay?

March 5th, 2026

It seems like the ads are everywhere these days—repair your enamel and reverse tooth decay with a tube of toothpaste! Are these claims too good to be true? Let’s dive into the science of tooth decay—how decay develops and how (and if!) it can be reversed.

Teeth can stand up to the powerful pressures of biting and chewing because over 95% of our enamel is made up of minerals. Calcium and phosphate ions in our teeth bond to form a crystal structure called hydroxyapatite. Because of the strength of this crystalline design, tooth enamel is the hardest substance in our bodies, even stronger than our bones. 

But bones, like most other parts of our bodies, are living tissue, which means that they can create new cells to replace old or damaged cells. Tooth enamel can’t regenerate new cells to repair itself. This means that when a cavity has made a hole in the tooth, the enamel can’t grow back. And, while enamel structure is very strong, it’s also vulnerable to damage—specifically, damage from acids. 

Our teeth are exposed to acids throughout the day, whether they are acids created by plaque bacteria or the acidic foods and drinks we consume. Acids dissolve mineral bonds, stripping calcium and phosphate minerals from the enamel and leaving weak spots in the tooth surface. This process is called demineralization. Demineralization is the first stage of tooth decay.

The good news? Our bodies are designed with a built-in defense mechanism to prevent demineralization from causing lasting damage. All through the day, saliva helps wash away acids in the mouth and bathes our teeth with new calcium and phosphate ions. These ions bond with the calcium and phosphate in our enamel, restoring enamel strength. This protective repair process is called remineralization. 

Now for the bad news. In the tug of war between demineralization and remineralization, saliva can only do so much. If your diet is heavy with acids, if you don’t brush away acid-producing plaque bacteria regularly, if you eat a lot of the sugars and starches which feed plaque bacteria, the remineralizing effects of saliva can’t keep up with the demineralizing effects of acids.

The first visible sign of demineralization is often a white spot on the tooth where minerals have been stripped from enamel. Studies have shown that enamel-strengthening toothpaste can be effective in this very first stage of tooth decay. Toothpastes which advertise enamel repair generally contain one or more of these ingredients:

  • Calcium Phosphate
  • Hydroxyapatite
  • Fluoride 

Toothpastes with calcium phosphate or hydroxyapatite contain calcium and phosphate minerals, the building blocks of tooth enamel. Studies have suggested that these minerals can replace the calcium and phosphate ions stripped from enamel. These toothpastes may or may not contain fluoride, which is something you should discuss with your dentist before deciding on a specific toothpaste.

Fluoride toothpastes remineralize enamel—and more! Fluoride ions are attracted to the tooth’s surface, and, when fluoride ions join with the calcium and phosphate ions there, they form fluorapatite. Fluorapatite crystals are larger, stronger, and more resistant to acids than hydroxyapatite crystals. And, once bonded with tooth enamel, fluoride attracts the calcium and phosphate ions in saliva to remineralize the teeth more quickly. 

Why consider enamel-repair toothpaste? 

Once enamel is gone, it’s gone for good. If excess demineralization isn’t treated, a weak spot on the tooth surface will continue to erode, growing bigger and deeper until it becomes a hole in the enamel. This is a cavity, and your dentist will need to treat and repair your tooth to prevent the cavity from growing and potentially exposing the tooth’s pulp to bacteria and infection. 

If you wear braces, you want to be especially careful about excess demineralization. Because it can be hard to brush and floss effectively with braces, white spots and discolored patches are a common concern for those with braces, especially on the enamel around brackets.  

Talk to Dr. Iwei Huang at our Chicago office about which toothpastes can help restore a healthy balance between the ongoing cycles of demineralization and remineralization when you have braces. While tooth-repair toothpaste can’t fix cavities, these products can often strengthen demineralized enamel and reverse this earliest stage of tooth decay.
