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. Betsy Meade at our Ypsilanti, MI 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.

Whether you’re using the latest note-taking app or old-school pen and paper, it’s a good time to start jotting down your resolutions for a healthier, happier New Year. To help the process along, we have some suggestions for traditional tooth-friendly resolutions—and also some ideas which might surprise you!

The Classics

• Brush and Floss Regularly

If you’re brushing for two minutes each time you brush, great work! Often, though, that two-minute window starts to shrink as our brushing routine becomes *too* routine. Try timing yourself while you brush normally. If you’re falling quite a bit short of two minutes, taking just a bit more time will be lots more effective in removing plaque from your teeth. And flossing is essential to remove irritating plaque and bacteria from between teeth and around the gumline.

Typically, dentists recommend brushing twice a day and flossing once daily. If the team at Meade Orthodontics recommends brushing and flossing more often to keep your brackets and wires free from food particles and built-up plaque, be sure to stick to this new schedule for a beautiful, cavity-free smile when your orthodontic treatment is complete.

• Use Fluoride Toothpaste

Fluoride toothpaste doesn’t just help prevent cavities by cleaning away plaque and food particles. It also helps make our enamel stronger. 

Acids created by plaque bacteria and acids in our diet dissolve minerals from tooth enamel, making it softer and more vulnerable to cavities. Fluoride bonds with the minerals in enamel to create an even stronger protective enamel coating. Check with your dentist or the American Dental Association’s website for the best toothpaste choices for healthy, strong enamel.

• See Your Dentist Regularly

Dentists typically recommend a full dental exam and cleaning twice each year. Your dental team will take X-rays as needed, examine your teeth, gums, and general oral health, and screen for oral cancer. A professional cleaning will remove plaque and tartar, which is especially important for gum health and for protecting the enamel near your brackets and wires, where plaque tends to build up.

Being proactive with your dental care means you’ll be sharing your healthy smile all year long—as well as discovering any potential problems before they can develop into major problems!

The Surprises

• Chew (Sugarless) Gum

When you’re not producing enough saliva, you feel the effects of dry mouth, including sore throat, difficulty swallowing, and bad breath. Another side effect? Poorer dental health. 

Saliva helps neutralize the acidic foods we eat, washes away bacteria and food particles, and contains minerals like calcium and phosphorus which remineralize tooth enamel. Chewing sugarless gum encourages saliva production. Check with Dr. Betsy Meade to see if it’s okay to chew sugar-free gum if you wear braces, and, if you use aligners, be sure to remove them before chewing and brush before putting them on again.

• Don’t Brush Right After Eating

Brushing after a meal is great to remove food particles like sugars and carbs which stick to our teeth—and braces—and which the bacteria in plaque thrive on. But if you’ve been eating or drinking acidic foods, it’s best to wait about an hour before brushing. 

Acids in foods, like acids created by bacteria, weaken tooth enamel. Brushing right away can be abrasive and damage enamel, but if you wait for an hour, the minerals in saliva have a chance to remineralize and restore your enamel strength.

• Toss Your Toothbrush

Not that we mean give up brushing altogether! But your toothbrush bristles start to fray and fan out after several months, meaning that you won’t be getting the full cleaning effects of your great brushing technique. Put a note on your calendar to replace your brush every three to four months for the best in plaque removal.

If you’re already following all these suggestions for protecting your dental health, resolve to keep up the good work! If not, give these easy-to-follow recommendations a try. Protecting your dental health is essential to gift yourself a new year filled with happy, healthy smiles in Ypsilanti, MI.

We’ve been celebrating the new year for a really, really long time. It goes way back, but it started formally in 1582, when Pope George XIII made January 1^st the official holiday for ushering in the new year. The idea was to yell, cheer, and blow horns to scare away all the evil spirits of the previous year with the hope that the new one would be filled with happiness and opportunity.

While scaring away evil spirits isn’t what’s on our mind these days, we still ring in the New Year by cheering and hollering with friends and family. It’s a time to set new goals, refocus on old ones, and look forward to all the surprises the coming year will bring.

Whether you’re saying hello to the New Year snuggled up at home on your couch in the Ypsilanti, MI area or by gathering your friends for a social celebration, here are some tips to help ensure you welcome this new chapter with a smile.

Tips for a great New Year’s Eve celebration from Meade Orthodontics

• Stay safe. This one’s vital, because nothing puts a damper on your party like an emergency trip to the hospital. Stay responsible and try to plan ahead, whether that means taking a taxi, staying with a friend, or recruiting a designated driver. Do what you have to do to keep yourself and everyone around you safe.
• Spend time with the people you love most. The way we see it, the whole point of the holiday season is to cherish your family and friends. Regardless of what you’re doing, make sure there’s something for everyone. It’s essential to do something the whole group will enjoy!
• Smile! Whether you get all dressed to go out or have a quiet gathering with family and friends, make sure you accessorize with a smile. There’s always something to smile about!

We can all agree that change can be scary sometimes, but ringing in the New Year is an observance we all welcome with open arms. We hope you’ll enjoy this transitional holiday in a fun, healthy, and safe way. You have endless possibilities ahead of you!

From Dr. Betsy Meade, have a fantastic New Year!

When most patients ask Dr. Betsy Meade this question, they're thinking strictly about sugar content — cut out the bacteria-feeding sugar that's present in regular soda by opting for a diet soda and it will be better for your teeth. That seems logical, right? Well, there's a bit more to it than that. Let's take a closer look at how any kind of soda can affect your dental health.

Diet Soda – Why it can also lead to tooth decay

The main culprit in these drinks that leads to decay is the acid content. Diet sodas and other sugar-free drinks are usually highly acidic, which weakens the enamel on your teeth and makes them more susceptible to cavities and dental erosion. The level of phosphoric acid, citric acid, and/or tartaric acid is usually high in sugar-free drinks so it's best to avoid them.

Some patients also enjoy drinking orange juice or other citrus juices. These drinks are high in citric acid and have the same effect on the enamel of your teeth.

So what about regular soda?

We know the acidity of diet sodas and sugar-free drinks contributes to tooth decay, so what about regular soda? Like we alluded to earlier, regular soda is high in sugar — a 12 ounce can contains roughly ten teaspoons of sugar — and sugar feeds the decay-causing bacteria in the mouth. This also includes sports drinks and energy drinks, which are highly acidic and loaded with sugar too. So these drinks are a double-whammy of sugar and acidity your teeth and body simply don't need.

The problems caused by both diet and regular soda is exacerbated when you sip on them throughout the day. If you drink it all in one sitting, you won't be washing sugar and/or acids over your teeth all day long and your saliva will have a chance to neutralize the pH in your mouth.

The best beverages to drink and how to drink them

Drinking beverages that are lower in acid is a good step to take to keep your enamel strong. According to a study conducted by Matthew M. Rodgers and J. Anthony von Fraunhofer at the University of Michigan, your best bets are plain water, black tea or coffee, and if you opt for a soda, root beer. These drinks dissolved the least amount of enamel when measured 14 days after consumption of the beverage.

If you still choose to drink soda, diet soda, sugar-free drinks, or juices here are some other tips to lessen tooth decay:

• Drink your soda or acidic beverages through a straw to minimize contact with teeth
• Rinse with water immediately after consumption of the beverage
• Avoid brushing your teeth between 30 minutes to an hour after drinking the beverage as this has been shown to spread the acids before your saliva can bring your mouth back to a neutral pH
• Avoid drinks that have acids listed on the ingredients label
