The History and Mythology of the Tooth Fairy

April 30th, 2025

While the last baby teeth generally aren’t lost until age ten or 11, most children stop believing in the tooth fairy by the time they're seven or eight. Of course, children are more than happy to play along with the game when there’s money at stake! While it is impossible to know what the tooth fairy does with all those teeth (are they labeled and stored like museum pieces in a giant fairytale castle?), it is possible to trace the history and myth of the tooth fairy to several cultures and traditions. Dr. DeCasperis and our team learned about some interesting myths about the tooth fairy!

The Middle Ages

Legend has it that Europeans in the Middle Ages believed a witch could curse someone by using their teeth, so it was important to dispose of baby teeth correctly. Teeth were swallowed, buried, or burned. Sometimes baby teeth were even left for rodents to eat. Despite being pests, rodents were valued for their strong teeth; it was generally believed a tooth fed to a rodent would lead to the development of a healthy and strong adult tooth.

Eighteenth Century France

The tooth fairy myth began to show more characteristics of a conventional fairytale in 18th century France. La Bonne Petite Souris, a bedtime story, tells the strange tale of a fairy that changes into a mouse to help a good queen defeat an evil king. The mouse secretly hides under the evil king’s pillow and defeats him by knocking out his teeth.

Scandinavian Lore

So, why does the tooth fairy leave money under the pillow? The idea of exchanging a tooth for coins originated in Scandinavia. Vikings paid children for a lost tooth. Teeth were worn on necklaces as good luck charms in battle. While the idea of exchanging a tooth for coins quickly spread throughout the rest of Europe, a fierce, horn-helmeted Viking is far cry from the image of a fairy collecting teeth.

While the tooth fairy as children know her today didn’t make an appearance until the 1900s, tooth myths and rites of passage have existed in numerous cultures since the dawn of time.

The Best Brush of the Day

April 23rd, 2025

Imagine that you’re only going to brush your teeth once tomorrow. Don’t worry, we know you would never skimp on your dental hygiene like that, but let’s just pretend for a moment. When would be the best time to brush? When you wake up? During the day? Or perhaps before you go to bed?

Actually, whenever you choose to brush, you’ll receive important overall dental benefits as well as specific benefits tied to the time of day. Let’s explore your daily schedule to see why.

Brushing in the Morning

Brushing when you first jump out of bed produces several positive results.

  • Cleaning plaque from your teeth

Plaque is a sticky film made up of oral bacteria, food particles, and saliva. As you sleep, these oral bacteria multiply and produce acids which attack the minerals in your enamel, leaving weak spots which, over time, can become cavities. Brushing removes these bacteria and acids from your enamel before they cause serious harm.

Moreover, plaque hardens if it’s left undisturbed, turning into tartar in a relatively short time. And once plaque becomes tartar, it must be removed by a dental professional. Brushing first thing in the morning removes this plaque buildup and helps prevent tartar from forming.

  • Fresh breath

That bacterial growth we mentioned? It’s also responsible for morning breath. If nothing else, brushing when you wake up means greeting a fresh day with fresh breath, and that’s reason enough to pick up your brush in the morning.

Brushing During the Day

Brushing after meals and snacks also has a lot to recommend it.

  • “Leftovers” lead to cavities

Foods, especially foods rich in sugar and carbohydrates, are converted by oral bacteria into acids which weaken enamel and lead to cavities. When food particles remain in the mouth after a meal, bacteria have more time and more fuel to manufacture these acids.

  • Acidic foods also affect your teeth

If you have eaten something acidic, such as citrus fruits, sodas, or pickled anything, the acids from these foods can temporarily weaken the mineral strength of your enamel. But brushing immediately after eating or drinking acidic foods can damage weakened enamel. Better to rinse well with water and brush after half an hour or so.

Brushing at Night

Growing up, you probably received regular reminders to brush before bedtime—for several really good reasons:

  • Saliva production slows while you sleep

During the day, saliva helps to wash away food particles and neutralize acidity in our mouths. It also contains proteins and minerals which help keep tooth enamel strong. But as we sleep, saliva production slows dramatically, and our bodies can’t remove bacteria and acids as effectively.

  • Food particles fuel bacterial growth

If you haven’t brushed since morning, you’ve accumulated a whole day’s worth of food particles from meals and snacks. Remember, oral bacteria use the sugars and carbs we eat as fuel to produce the acids which attack our tooth enamel throughout the night.

  • Brushing helps prevent both of these problems

Brushing your teeth before bed not only cleans away the accumulated food particles of the day, but also eliminates the plaque and bacteria which would have a much easier time sticking to your teeth without that daytime saliva flow to wash them away.

So, When’s the Best Time to Brush?

In the morning, during the day, at night —there are solid advantages to brushing any time of day. The question isn’t so much when to brush as how often you should brush.

While many dental professionals consider brushing before bedtime as the most important brush of the day, brushing at least two full minutes, at least twice during a 24 hour period, is a necessity for basic dental hygiene. (And don’t forget to floss at least once each day.)

If you wear orthodontic appliances, if you’ve been eating sugary snacks, if you’re showing signs of gingivitis or getting more than your share of cavities, if you want to reduce the chance of plaque and tartar buildup, or if you simply want to make sure you’re doing everything you can to maintain your overall dental health, brushing after meals is also highly recommended.

Three Reasons We're Fans of Fluoride

April 16th, 2025

Why all the fuss about fluoride? Your dentist recommends it, your toothpaste is formulated with it, most of our drinking water contains it. Just what is it about this mineral that makes dental professionals sing its praises? Read on for three good reasons why fluoride is a healthy choice for healthier teeth.

  1. Fluoride Works!

Fluoride is an attractive option for protecting your teeth—and we mean that literally. Fluoride protects the surface of your teeth by working on a molecular level to attract minerals which strengthen enamel and help prevent cavities.

Our tooth enamel is mostly made from calcium and phosphate ions. These elements combine to form hydroxyapatite, strong crystals which make up about 95% of our enamel. Hydroxyapatite is so strong, in fact, that tooth enamel is the hardest part of our bodies. What can go wrong?

Acids. Acids created by the bacteria in plaque and the acids in our diet strip away the calcium and phosphate ions in enamel, weakening the surface of the tooth. This process is called demineralization. Over time, weak spots become bigger as acids eat through enamel to the inner tooth, causing decay and cavities.

So, what can fluoride do?

First, fluoride helps remineralize tooth enamel. Fluoride is attracted to the tooth’s surface and bonds with its minerals. It also attracts the calcium and phosphate ions which are found in our saliva to restore any minerals which have been lost. This process helps repair any weak spots that might have begun to form.

But fluoride does more than restore and repair tooth strength—it improves it! Fluoride ions join with calcium and phosphate to form fluorapatite crystals, which are larger and stronger than hydroxyapatite crystals.

Want more? Fluoride may interfere with bacterial plaque’s ability to produce acids. Since plaque and its acids are a major cause of gum disease, brushing with a fluoride toothpaste is a great way to help prevent plaque buildup around and below the gum line—buildup that leads to irritated, inflamed, and infected gum tissue.

  1. Fluoride Is Doubly Effective

Fluoride works both externally and internally. We just looked at how fluoride helps keep teeth strong when applied to the outside of the teeth. This is called a topical application. Systemic benefits come the fluoride we consume in our diets.

Fluoride isn’t found in many foods, but it is found naturally in lakes, rivers, and other water sources. When the local water’s fluoride level is low, many communities add fluoride for its proven ability to prevent cavities. Water fluoridation is safe, has been studied for decades, and has been shown to reduce the risk of cavities by 25% or more for both children and adults.

Systemic fluoride is especially important for your child’s dental health. This is because fluoride incorporates with minerals in the adult teeth while they are growing and developing, creating stronger, more cavity-resistant teeth even before they erupt. Most adult teeth have finished forming around age eight, so, if your community doesn’t have fluoridated water, it’s a good idea to discuss other options with your child’s dentist.

And we grown-ups benefit, too! When you drink fluoridated water, you’re increasing the amount of fluoride in your saliva. Just like fluoride toothpaste, saliva bathes your teeth with fluoride ions, strengthening the tooth surface, and helping to neutralize the acids which damage teeth and gums.

  1. It’s Easy to Get Fluoride Protection

Most toothpastes are formulated with fluoride, so you’re getting the enamel-strengthening benefits of this mineral whenever you brush—at least twice each day. Since children can’t really grasp the “rinsing” and “spitting” steps of the brushing routine just yet, talk to Dr. DeCasperis about how to introduce tiny amounts of fluoride toothpaste to your child’s dental routine. Baby steps!

Because so much of our drinking water is fluoridated, most of us really don’t have to think about how to get the recommended amount of fluoride each day. If your community’s water is low in fluoride, we can help you here as well. Prescription fluoride rinses, gels, supplements, and other treatments are available to make sure that your teeth are well-protected, wherever you may live. We will let you know which products are best for you and how often to use them during your next visit to our Lebanon, NJ dental office.

Fluoride isn’t, of course, the only way to look out for your dental health. Proper brushing and flossing are still essential for removing plaque. Check into sealants for both kids and adults for long-lasting protection for chewing surfaces. But when it comes to a proven cavity-fighter and plaque-reducer that is simple to use, effective, and easily available—is it any wonder we’re big fans of fluoride?

A Spot of Trouble?

April 9th, 2025

Your smile is in the spotlight every day, helping you greet the world with confidence! But when you’re self-conscious about discolored spots on your teeth, it’s time to get some professional advice to deal with these troublesome tints.

Discolored patches, both dark and light, can develop for a number of different reasons. Some markings are cosmetic only, and some spots require treatment. Some can be removed with a professional cleaning, and some might require more serious restoration. Let’s have a look at some of the common causes of enamel discoloration.

  • Cavities

Decayed enamel can appear as a brown spot on the tooth. A dark edge around a filling might mean decay underneath.

Regular checkups at our Lebanon, NJ office will help catch small cavities before they become big ones. If you need a filling, the filling color can be matched to your tooth color for an undetectable restoration.

  • Demineralization

Bacteria in plaque produce acids, which attack our teeth. These acids erode minerals such as calcium and phosphorus from enamel, leaving a weak spot that is vulnerable to decay. This process is called “demineralization,” and often leaves a whiter spot on a tooth where minerals have leached away. Common reasons for demineralization are neglecting dental hygiene, failure to clean around braces, and a diet filled with sugary and acidic foods.

Fluoride and enamel-strengthening toothpastes, a healthy saliva flow, and a balanced diet help our teeth “remineralize,” bathing teeth in minerals that can help replace those that have been lost. But if you have lingering white spots due to demineralization, Dr. DeCasperis can provide some options, including whitening, microabrasion, and veneers.

  • Fluorosis

Fluorosis is a cosmetic condition caused by exposure to too much fluoride while the permanent teeth are still forming (generally, during the years before a child’s eighth birthday). Small white spots and patches are a common result of mild fluorosis. In more serious cases, teeth can be pitted and stained with brown, gray, or black spots.

Preventing fluorosis begins in early childhood. Talk to Dr. DeCasperis about fluoride levels in local tap water if you have any concerns. Use only the recommended amount of toothpaste (the size of a grain of rice for children three and under; the size of a pea for children three to six), and show your child how to spit out toothpaste and rinse after brushing. Keep fluoride toothpastes and other fluoride products out of the reach of young children. Don’t give children fluoride supplements or fluoride rinses without discussing it with Dr. DeCasperis.

If your own teeth have been affected by fluorosis, talk to us. Again, this is a cosmetic condition affecting otherwise healthy teeth. Whitening treatments can be helpful in mild cases, microabrasion has been effective for mild to moderate cases, and, for severe cases, cosmetic restorations such as bonding and veneers are an option.

  • Tartar

Are you seeing an accumulation of dark brown spots and stains on your teeth, especially between the teeth and at the gum line? This might mean that you have tartar buildup. When you brush plaque away every day, your enamel stays smooth and clear. But when plaque builds up over time, it hardens and becomes tartar.

How hard is tartar? So hard that it can only be removed with a professional cleaning. Eliminate this source of spots and staining with twice daily brushing and daily flossing, and make sure regular professional cleanings are on your calendar.

  • Other Causes

Medications taken while teeth were developing (notably, antibiotics in the tetracycline family) can cause discoloration. Medical conditions such as celiac disease and enamel hypoplasia can affect both tooth color and enamel formation.

Cosmetic treatment and restorations can help with discoloration caused by medications, and restorations such as bonding, veneers, and crowns can restore tooth appearance and function when medical conditions cause imperfections in enamel color and structure.

If you’re unhappy with the overall whiteness of your smile, a professional whitening might be just what you’re looking for. If specific patches, streaks, and spots of a different color are dimming your bright smile, it’s time for an exam. Dr. DeCasperis will be able to tell you the reason for any discolored enamel as well as present you with all your treatment options. Put the spotlight back where it belongs—on your healthy, confidant smile!
