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. Joseph Brogan at our Philadelphia, PA 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.

If Dr. Joseph Brogan and our team recommend a Hawley retainer to complete your orthodontic treatment, you’re getting a classic. This retainer, invented by Dr. Charles Hawley, has been in use since the early decades of the twentieth century.

But this isn’t your great grandmother’s pink plastic retainer! The look of today’s Hawley retainer has really evolved from its early days as the “Hawley bite plate”—and pink is now a choice instead of an inevitability. In fact, you can choose from any number of colors, patterns, and designs to create a retainer that is uniquely you.

Each Hawley retainer is customized to fit your mouth and teeth perfectly. Wire clasps and a labial bow wire are securely attached to an acrylic base based on a model made from your teeth and mouth.

Your retainer is designed for function—the bow wire makes sure your teeth stay in the perfect position while your bones and ligaments get strong enough to hold them in place. The acrylic base, of course, is also functional—but that doesn’t mean you can’t have fun with it!

Retainer bases can be formed in different ways.  One type of retainer model uses pre-formed acrylic discs for the base, and these are available in many pre-formed colors and patterns. Another type of retainer builds the base by alternating several applications of liquid and powder acrylics, layer after layer. This process allows the retainer technician to create one-of-a-kind designs.

What are some of the ways to make your retainer uniquely yours?

• Color—whether deep tones, pastels, electrics, neon, or metallic, you can find an appealing shade in the color chart. Or, if you want your retainer to keep a low profile, choose a clear or a color-coordinated pink tone.
• Glow in the Dark—if you don’t want your retainer to keep a low profile, this might be just the look for you!
• Glitter—accessorize your sparkling smile with a sparkling retainer.
• Patterns—stripes, polka dots, geometric shapes—even animal patterns are possible.
• Color Combinations—why choose one color when you can have a marbled swirl of your favorites? Or a tie-dye look? Or team colors?
• Acrylic Designs—a colorful design that captures your personality is available with some creative acrylic artistry. Rainbows and flags, hearts and flowers, ladybugs, and spider webs are just some of the options on hand.
• Picture Perfect—for that special hobby, pet, team, or other personal favorite, decals or pictures can be applied under a layer of clear acrylic.

Hawley retainers are made to last, so choose your design with years of use in mind. Talk to our Philadelphia, PA team about the custom looks which are available to celebrate your unique personality. After all, there’s nothing more personal than your smile!

You’re biting into something delicious, and, Ouch! You bite into something you didn’t mean to—the inside of your tender cheek.

Painful moments like this happen every now and again. But if you find that more frequent cheek biting means that you’re extra-cautious when eating or speaking, if you wake up with sore cheeks in the morning, or if you catch yourself gnawing on your cheeks during the day, it’s time to see Dr. Joseph Brogan.

Causes of Cheek Biting

Many of us experience the occasional cheek chomp when we’re eating or talking. No fun! Besides the pain, a bite can cause broken skin, inflammation, a canker sore, or a cyst. Luckily, the discomfort from these accidental bites generally resolves after a few days.  

Sometimes, though, biting becomes a more frequent annoyance. Regular bites can be caused by several conditions. One of the most common?

• Orthodontic Misalignment

If you notice that you seem to be biting your cheek a lot when eating or speaking, it could be an orthodontic problem. When your teeth or jaws don’t align properly, if your mouth is small in proportion to your teeth, or if your teeth have shifted over time, your cheeks can feel the consequences! Dr. Joseph Brogan can help you discover if a misaligned bite is the source of your biting problems.

But it’s not just orthodontic problems which can cause painful cheek bites. Other causes can include:

• Bruxism

Bruxism is a medical term for tooth grinding. If you clench or grind your teeth as you sleep, it’s hard on your teeth and on your jaws. And for some people, that nightly gnashing causes cheek biting as well.

• Wisdom Teeth

Most of us don’t have the room to welcome four new—and large—teeth. As the wisdom teeth come in, they can cause bites, especially if they erupt leaning outward toward your cheeks. They can also push your other teeth out of place.

Treatment Options

Why visit our Philadelphia, PA orthodontic office? A one-time bite can be extremely uncomfortable, and might lead to inflammation or a sore spot inside your mouth. Usually, these reactions fade in a short while.

But what about continuous biting? Regular biting injuries can lead to bigger problems. Tissue can get thicker or erode. Scar tissue can build up inside the mouth. Ulcers and other sores can become larger and more painful.

If you’ve been biting your cheeks more often, your orthodontist can diagnose the cause and offer you treatment options depending on the reason for this frequent biting:

• Orthodontic Treatment

Orthodontic treatment can improve tooth and bite alignment—and can eliminate those painful cheek bites if misalignment is what’s causing them. Today’s orthodontics offers more options than ever before, for both adults and kids.

• Traditional braces are more effective—and more subtle—than ever, with brackets which are smaller or come in clear and ceramic styles.
• Clear aligners are a convenient, almost invisible way to treat misalignment with a series of trays which gradually improve alignment with each new set.
• Lingual braces are attached to the back of the teeth, so there are no visible brackets and wires.
• Functional appliances can improve and correct bite issues which braces or aligners alone can’t treat as effectively.

Whatever the reason for painful cheek biting, you deserve to eat and speak and enjoy your day without constant “Ouch!” moments affecting your comfort and health. If these moments are happening all too often, visit our Philadelphia, PA office for the answers to your biting problems.

How long? Well, a beautiful smile is both science and art—proper teeth and jaw alignment united with aesthetically pleasing results. Orthodontists achieve both these outcomes with a careful analysis of any dental and facial problems, a treatment plan designed specifically for each patient’s needs, and adjustments through each phase of treatment to carefully bring about that beautiful smile.

And that’s a long way of saying, there’s no one, standard answer as to how long a patient will wear braces because there is no one, standard patient. Often, treatment takes from 18 to 24 months, but it can be months shorter or months longer depending on a variety of different circumstances.

• Different Needs

Your orthodontic needs and goals will generally determine your treatment time. Some patients need only a bit of alignment, which can lead to a fairly short orthodontic experience. Some have malocclusions such as crossbites and open bites that require more complex and lengthy treatment.

And, while we used to think of orthodontics as a teenage rite of passage, that’s certainly no longer the case. Some children will need two-phase orthodontic treatment, where early procedures before the adult teeth even come in ease the way for any necessary second stage treatment when the permanent teeth arrive years later. And some adults will want orthodontic work later in life, where denser bone tissue might lead to (somewhat) longer treatment.

• Different Appliances

Today’s orthodontics offers you many choices in appliances. Lingual braces are an almost invisible option, with brackets and wires on the inside of the teeth. Aligners use clear, custom molded trays to move the teeth into a better position with each new tray. Even traditional braces are smaller and sleeker today, with metal or less visible ceramic brackets. Depending on the orthodontic goals you want to achieve, there might be a small difference in the amount of time each appliance will take to get you to those goals. Talk to us about all your options and what they mean for treatment time.

• Different Levels of Participation in the Process

This is one area you can make a real difference! If you follow our instructions for using your appliances most effectively, you’ll make progress as quickly as possible. If you have aligner trays, be sure to wear them for as long as directed each day. If you have rubber bands attached to brackets on your upper and lower teeth, wear them for as many hours as required, because these little bands are actually the tools that are moving your teeth into alignment. If you don’t wear your braces or aligners as directed, not much is going to happen, and certainly not on schedule.

Give our Philadelphia, PA office a call, and we can discuss your goals for creating your very best smile. Once we’ve decided on a treatment plan, Dr. Joseph Brogan can give you a fairly good estimate as to how long your particular treatment will take. And, when you get to share that beautiful, healthy smile, the time you’ve spent achieving it will be well worth it!
