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. Sung Lee at our Puyallup, WA 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.

School’s out. The barbecue’s fired up. T-shirts and shorts are back in style. Sandy beaches and sidewalks are sizzling. Summer’s officially here, and it’s time to get back into hot weather mode. This means getting back into some healthy summer habits.

Be Ready to Hydrate!

Warm weather can lead to dehydration before you know it. And water does more than hydrate—it rinses away food particles after eating or snacking, neutralizes enamel-eroding acids in the mouth, and helps us keep up healthy levels of saliva. 

• A reusable water bottle is a summer shopping list must. When you’re out walking, hiking, exercising, or camping, you can’t always be sure you’ll have fresh water available. Fill your water bottle before you leave home—you’ll help yourself stay hydrated, save money, and protect the environment, too!
• When you’re on the go, rinse with water after snacking to help remove food particles from teeth and braces.
• Go light on the sports drinks and sodas when planning your summer menus. They’re often filled with sugars and acids—two very unhealthy ingredients for your teeth. 

Restock Your Sunscreen

Sunscreen helps protect skin of all shades and all ages. Exposure to ultraviolet rays is known to cause skin cancer and premature aging. Lip tissue is thin and delicate, especially at risk from the sun’s damaging UV rays. 

• Check your sunscreen for its expiration date. Protective sunscreens and lip balms lose effectiveness once that date has passed.
• Some sunscreens are designed for use on lips. If yours isn’t, look for a protective lip balm. All of your sunscreens and balms should have an SPF (Sun Protection Factor) of 30 or higher.
• Bring your sunscreen and balm with you when you’re out and about, and reapply every two hours, or sooner if you’re eating, drinking, or getting wet.

Prep for Summer Adventures

If you’re travelling this summer, make sure the right dental and orthodontic supplies are part of your gear. A travel size toothbrush and toothpaste, a well-ventilated toothbrush case, and your orthodontist’s and dentist’s emergency contact information are basic necessities. If you wear braces, add dental wax and extra rubber bands. If you have aligners or a retainer, don’t forget your case.

Once you have the basics, you can tailor your kit to your summer plans:

• Flying? Make sure every liquid, gel, or aerosol you’ll need is the proper size for carry-on flight rules, 3.4 oz (100 ml) or less. Toothpaste and mouthwash are included in these categories, so look for travel sizes in your favorites. 
• Going overseas? Don’t forget plug adaptors or voltage converters if needed for your electric toothbrush.
• Camping? An emergency kit with cotton rolls, over-the counter pain relief, oral pain relief gel, dental wax (for damaged braces or a broken tooth), and even temporary fillings and a tooth preservation kit can be crucial in case of unexpected dental injuries.

Make Sure Dental Care Is on Your Summer Calendar

Laid-back summer days are the best, but laid-back dental care really isn’t! Follow your healthy dental routine even during the lazy days of summer.

• Keep up with your brushing and flossing. Brush two minutes twice each day with a fluoride toothpaste, and floss at least once a day—or more often as your orthodontist recommends.
• If you’re planning a trip, don’t ignore warning signs. If you have tooth pain or sensitivity, see your dentist to treat any problems before you’re cruising at 30,000 feet or enjoying a remote campout miles from anywhere.
• See your orthodontist as scheduled, and make sure to let the office know if you have travel plans which might disrupt your regular treatment schedule.
• Keep your appointments for dental exams and cleanings to ensure year-round dental health.

Whether you’re basking in the warm outdoor weather, relaxing in the shade with a cool drink and a good book, on the road to adventure, or wherever your summer plans take you, we hope these easy tips will help you create a summer filled with bright, healthy smiles.

Most kids love candy; actually, most people in general love candy. So when it comes time for you to get braces there can often be a natural conflict between candy consumption and maintaining the integrity of your braces. For that reason, Dr. Sung Lee and our team know that it’s good to know which types of candy are not good for your braces. To better illustrate, here are some candies that you will want to avoid.

Caramel

Caramel is a sweet and often exceedingly sticky and chewy type of candy that just does not mix well with braces. Caramel can cause a mess in regular teeth, but teeth with braces are a whole other story. The sticky candy can very easily get lodged and stuck between the teeth, gums, and braces, making for a difficult task of cleaning your mouth. And if your teeth don't get cleaned properly, cavities can easily form. If you get cavities while you have braces, that could mean additional appointments at our Puyallup, WA office and an extended treatment time.

Salt Water Taffy

Another sticky and chewy candy to avoid with braces is salt water taffy. For many of the same reasons as caramel, it is best to avoid taffy until you get your braces removed. It may be a long wait, but when it comes to the health of your teeth, and the purpose of your braces, it really is best to avoid taffy.

Popcorn

Popcorn of any kind is best to avoid when you have braces. The kernels can easily do damage to the braces as you chomp on them, and they can get stuck between your teeth and the braces causing discomfort and further complications. In this sense it does not matter which flavor of candy popcorn you eat, all popcorn is bad news until you get your braces off.

Generally speaking, any candy that is chewy, crunchy, or sticky is not a good idea to eat with braces in your mouth. These types of candy will make life wearing braces much more difficult than if you were to just wait until your braces come off. With a little patience you will be back to eating all your favorite candy again, and with straightened teeth at that.

Memorial Day is not only a federal holiday in the United States, but it is a day of observance and remembrance of those who died in service. Originally known as Decoration Day, this solemn day has been marked on calendars since the end of the American Civil War as a day to commemorate both the Confederate and Union soldiers who fought and died in the war.

Marking the graves of fallen soldiers with flowers, wreaths, or other tokens has been practiced throughout history, but it wasn't until the mark of the end of the Civil War that a special day was decided upon as the one to spend in remembrance. By 1890, every state in the country was observing Decoration Day. It wasn't until 1967 when the name formally changed from Decoration Day to Memorial Day, in order to encompass all fallen American soldiers in all wars and conflicts. In June of 1968, Congress moved the official date of Memorial Day to the last Monday in May in order to create a three day weekend.

Today, while there is certainly an air of remembrance on Memorial Day, it has become more a day of spending time with family, friends, and other loved ones. This day is also heralded as the start of summer, with many schools finishing for the year around this time. Our team at Sung Lee Orthodontics remembers it as a day to take solace and remembered those lost.

Traditional observances of Memorial Day are still held, and they often involve raising the American Flag then lowering it to a half-staff position until noon, and then raising it once again to its full height afterwards. The flag is lowered to remember those who've lost their lives while in service to their country, and then it is raised to signify our willingness to not let their sacrifice be in vain.

From community parades in the Puyallup, WA area, backyard cook-outs, and fireworks to formal ceremonies, Memorial Day is commemorated in many different ways. No matter how you choose to spend this day, take a moment to remember those who've lost their lives in an effort to preserve our freedom.
