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. Thomas Shipley at our Peoria, AZ 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.

Taking care of your oral health involves a daily regimen of brushing, flossing, and rinsing to prevent tooth decay and bacterial infections. Though you may have asked us which toothbrush to use, few patients at Shipley Orthodontics ask about mouthwash.

However, different mouthwashes you might choose will have varying effects on your oral health. So which type is best for you?

Gum Health

Antiseptic mouthwashes are designed to reduce the majority of bacteria on and near the gum line. Using an antiseptic mouthwash can help decrease your chances of developing gingivitis. If possible, look for a mouthwash with antibacterial or antimicrobial ingredients.

Fluoride

Fluoride is beneficial for oral health and can help prevent tooth decay. If you drink a lot of bottled water without fluoride, we may recommend that you purchase a rinse with fluoride in it.

Bad Breath

Although mouthwash is designed to prevent bacterial build-up within the mouth, many people use it to combat bad breath. Most mouthwashes will help eliminate the bacteria that cause bad breath, and some are specifically designed to do so.

However, if bad breath is a chronic problem that requires daily treatment with a mouth rinse, contact Shipley Orthodontics to discuss your symptoms.

American Dental Association Approval

The ADA reviews mouth rinses for safety and effectiveness. A mouthwash with the ADA Seal of Approval will meet strict criteria, and will have scientific evidence or clinical studies that support the claims of the manufacturer. If possible, select a mouthwash that bears the ADA Seal of Approval to ensure you are using a quality rinse.

Considerations

If you are unsure as to which mouthwash is right for you, contact our Peoria, AZ office or ask Dr. Thomas Shipley during your next visit. Also, be sure to keep mouthwash out of the reach of children, as it contains alcohol and other substances that could be harmful to them. Avoid letting children under age six use a mouth rinse, and discontinue use if you experience a burning sensation in the soft tissues of your mouth.

Healthy teeth make you happy to share your smile with the world. But there’s more to your smile than its beauty! There’s a lot of hard work going on, too. 

Teeth Are Designed for Efficient Eating

Because humans are omnivores, we can eat both meat and plants. That’s why our teeth have different shapes—they’re meant to help us process different types of food. 

• Incisors, our front teeth, have sharpish edges to help cut through meats and other firm foods when we bite.
• Canines, the pointed teeth, help tear food into bite-size portions.
• Premolars are flat topped teeth with two cusps, raised points which help us grind food.
• Molars are the flat-topped teeth in the rear of the mouth. They have four cusps to grind and crush food into a paste-like consistency. 

So: Incisors and canines bite and tear food into smaller pieces, which molars and premolars then crush and grind into a paste. Bite, tear, crush, grind—why all this food aggression? Because that’s the key to healthy digestion. 

Successful digestion begins with chewing. Chewing:

• Starts the process of breaking food down into digestible particles.
• Increases saliva production. Saliva binds food particles so that we can swallow easily.
• Expands the surface area of food particles, which allows the digestive system to extract nutrients more efficiently. 

When biting causes you pain, it can be hard to chew food. Swallowing becomes difficult when food particles are too large, and digestion becomes uncomfortable.

Bite pain can occur when there’s a deep cavity or an injured tooth, but it can also be caused when the teeth and jaws don’t fit together the way that they should. This misalignment is called a malocclusion, or bad bite. And while a malocclusion often makes eating more difficult, it can have further damaging effects as well.

Teeth Are Designed to Be Good Partners

While eating is probably the first thing that comes to mind when we think about dental duties, our teeth also work in coordination with other parts of our bodies. A malocclusion can interfere with these normally smooth interactions, affecting:

• Tooth and Jaw Health

Biting, chewing, and clenching put hundreds of pounds of pressure on our teeth and jaws. A misaligned bite misapplies this pressure, which can lead to damaged and unevenly worn teeth, tooth grinding, headaches, jaw pain, and other problems. 

• Speech

Our teeth work with our tongues and lips to form many of the phonetic sounds which make up speech. Try saying the word “teeth,” and see how your tongue and teeth work together! Misaligned teeth and jaws can affect speech development in children and pronunciation in children and adults.

• Face Shape

Our teeth and jaws help give shape to our faces. Alignment problems can affect facial symmetry and self-confidence.

You Can Help Your Teeth Work Their Best

Daily brushing and flossing, eating a healthy diet, and regular visits to your dentist for exams and cleanings help your teeth perform their many daily duties. But if bite problems are causing troubles with eating, tooth or jaw pain, difficulty speaking, or self-consciousness, it’s time to team up with your orthodontist. 

And just like your everyday dental care, orthodontic treatment works best with your active participation. 

• Make sure your teeth are their cleanest with careful brushing and flossing. You may need to brush and floss more often while you’re in treatment.
• If you wear braces, eat a braces-friendly diet. 
• Wear aligners, bands, or appliances for the hours recommended each day.
• Keep up with your orthodontic visits to keep your treatment on schedule.

Talk to your orthodontist to learn more about how to help your teeth work their best for you—and be ready to share that beautiful, hard-working smile!

On the last Wednesday in September, we celebrate “Women’s Health and Fitness Day.” Because your oral health plays such a large role in your general health and well-being, let’s look at a few of the ways you can treat yourself with the care you need and deserve at different stages of your life.

Puberty 

Puberty begins around the ages of 8 to 13, and typically lasts from 2-5 years. During this time, our bodies begin to produce the hormones estrogen and progesterone, which affect not just the reproductive organs, but our brains, hearts, skin, hair, bones, and more. These hormones can also affect our oral health.

• Gingivitis

Hormonal fluctuations make gum tissue more sensitive to irritants like plaque and bacteria. You might find that your gums are swollen, tender, red, or bleed easily. 

What you can do:

Keeping up with your dental hygiene is the best defense against gingivitis. Even if your gums feel a bit tender, it’s important to keep up with your brushing and flossing because proactive dental hygiene can reverse gingivitis before the condition becomes more serious. If symptoms persist, a visit to the dentist is in order.

Menstruation

• Menstruation gingivitis

Elevated hormone levels can also cause gingivitis during the menstrual cycle, usually beginning a few days before the start of your period and ending soon after your period begins. Some women also experience canker sores and swollen salivary glands during this window.

What you can do:

Be mindful of any oral changes during your menstrual cycle. Pay special attention to dental hygiene, and, if you develop canker sores, talk to your dentist or doctor about the best way to care for yourself while they heal.

Pregnancy

Pregnancy brings about many physical changes, including potential changes in your oral health.

• Pregnancy Gingivitis

Pregnancy hormones cause an increase in the blood supply to your gums while at the same time making them more vulnerable to irritation from bacteria and plaque. You may find that your gums are redder, more swollen, and more likely to bleed when brushing. 

• Loose Teeth

During pregnancy, increased hormone production helps relax and loosen ligaments and joints in preparation for birth. Teeth are held in place by ligaments, and you might be alarmed to discover your teeth are looser as well. Typically, this situation resolves when the baby is born.

• Pregnancy Granulomas

Some pregnant women may also experience pregnancy granulomas. These dark red swellings are benign tumors which appear along the gumline. These generally shrink on their own, but, if a granuloma is causing you pain or discomfort, your dentist can remove it surgically.

What you can do:

Let your dental team at Shipley Orthodontics know right away when you learn that you’re pregnant. You’ll get helpful advice about brushing and flossing techniques, pregnancy-related oral conditions to look out for, when to schedule dental treatment and cleanings, a tooth-healthy diet, and more.

Menopause and Later Years

As we age, there’s an increased risk of oral health issues.

• Osteoporosis

Osteoporosis causes loss of density in the bones—including the bones and bone tissue which hold our teeth in place. Studies indicate that women with osteoporosis suffer significantly higher tooth loss than women who don’t have the disease.

• Dry Mouth

Saliva helps protect the teeth from cavities by washing away bacteria and food particles and by neutralizing acids in the mouth. Reduced estrogen production, medications, and medical conditions such as diabetes can all cause dry mouth. 

• Gum Disease

About 2/3 of older Americans have gum disease, which is one of the leading causes of tooth loss in adults. Lower hormone levels have been linked to increases in periodontal diseases.

• Oral Cancer

Oral cancer is more common as we age, and, while men are affected almost three times as often as women, we should be aware of the common symptoms of oral cancer, including a sore in the mouth which doesn’t heal, a lump or thickening in the mouth, red or white patches on the tongue, gums, and other oral tissues, loose teeth, or persistent earaches or discomfort when eating or swallowing.

What you can do:

Visit your dentist and doctor for preventative care and whenever you are concerned about your oral health! Whether it’s helping you prevent osteoporosis and dry mouth or discovering dental and medical conditions early, when they are more likely to be treated successfully, regular visits to your dentist and doctor can help ensure that you have years of happy smiles ahead.

At Any Time of Life

Let’s talk a moment about something which isn’t limited to any one phase of your life—orthodontic treatment!

Straighter teeth and a healthier bite aren’t gender-related. Women and girls don’t have different orthodontic needs from men and boys. They don’t require different types of braces or appliances. But there is one difference in the sexes—women and girls choose orthodontic treatment more often. Good for us! And let’s encourage the men in our lives to do the same.

Why? Because orthodontic treatment does more than give you an attractive smile. You and Dr. Thomas Shipley work to create an attractive, healthy smile. A well-aligned bite can lead to healthier teeth and gums, more comfortable jaw movement, and even improved facial symmetry. And, while it helps to begin treatment early, while the bones are still forming, as long as our teeth and gums are healthy, we adults can reap the benefits of a beautifully aligned smile as well.

What you can do:

Today’s orthodontic treatment is more comfortable and effective than ever before. Women of all ages are benefitting from the latest treatment options, including smaller and lighter traditional braces, discreet aligners, and lingual braces attached to the back of the teeth. If you’ve always wanted straighter teeth, or if you have bite discomfort, or if your teeth have shifted with age, make an appointment with Shipley Orthodontics in Peoria, AZ for an evaluation. 

Missed the date this year? No worries! Women’s Health and Fitness Day is one day in September, but every day in the calendar is a good day to think about your oral health. Partner with your dentist, your doctor, and Dr. Thomas Shipley to help make your healthy smile something to celebrate all year long!
