The History and Mythology of the Tooth Fairy

February 4th, 2026

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. Drs. Arti and Ashi 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.

Ease up on your gums — don’t brush your teeth too hard!

January 28th, 2026

A lot of patients go at their teeth like they were sanding an old floor—that is to say, way too hard! Brushing too hard is probably the most common mistake patients make in their oral care routine, and it can be detrimental to the gums and teeth.

What can brushing too hard cause?

  • Receding gums
  • Bone loss around teeth
  • Loss of teeth
  • Tooth sensitivity, especially to hot and cold
  • Worn down enamel

Brushing too hard wears away at your gums, which can lead to the neck of the teeth being exposed. This part of the tooth isn't covered by hard enamel like the rest of the tooth and hence the soft inner layer, or dentin, is exposed. Dentin is very sensitive to hot and cold and much more susceptible to bacterial decay. Once the gums recede due to improper brushing, it’s usually irreversible.

How to brush your teeth properly

You know you're supposed to brush your teeth twice a day, so why not do it right? First and foremost, you should only ever brush with a soft bristled brush—not medium or hard—unless directed otherwise by Drs. Arti and Ashi. Unless you have braces or specific oral health issues, brushing twice a day for two minutes is usually plenty.

The main purpose of brushing is to remove plaque from your teeth and gums. Plaque is actually soft and is a buildup of bacteria, saliva, and food debris. You really don't need to brush hard to remove it, just make sure you aim your toothbrush at the gum line (where plaque grows) and brush in small circular motions, never a back-and-forth motion.

It's also wise to hold your toothbrush gently. People tend to brush harder the tighter they hold their toothbrush.

Still have questions about proper tooth brushing technique or gum health? Ask any staff member or Drs. Arti and Ashi during your next visit to our Issaquah office; we'd be happy to help!

Radiation and the Safety of Dental X-Rays

January 21st, 2026

It is not uncommon to be concerned about your safety when you have dental X-rays performed. Putting on a heavy lead vest may make you apprehensive. The benefits of dental X-rays far outweigh the risks when safety procedures are followed and the number of X-rays is limited to the required number.

About Dental X-rays

Intraoral X-rays are the most common, and include bitewing X-rays. These allow Drs. Arti and Ashi and our team at Issaquah Valley Dental Care to detect caries (cavities) and check the health of your bone and root structure. Extraoral X-rays provide the information we need to monitor your jaw and temporomandibular joint (TMJ), as well as look for impacted teeth and tooth development.

X-ray Safety

A set of four bitewing X-rays exposes you to about 0.005 mSv (millisievert) of radiation, which is equal to the amount of radiation you receive in an average day from natural sources. A panoramic X-ray exposes you to about twice the amount of a bitewing. In both cases the risk is negligible and worth the diagnostic benefits.

Guidelines from the American Dental Association are offered for individuals who are not at high risk for cavities. Children in this group should have X-rays every one or two years. Teenagers should have X-rays every one-and-a-half to three years. Adults can go two to three years between X-rays. If you are at higher risk, yearly X-rays are not harmful and can save your teeth.

No matter what type of X-ray you are having, it is extremely important to tell Drs. Arti and Ashi or one of our technicians if you are pregnant or may be pregnant. If you are concerned about the number of X-rays you are having done, or about any radiation you are exposed to, please give us a call at our convenient Issaquah office and talk to us about your concerns.

Losing a Baby Tooth

January 14th, 2026

It seems like yesterday. There you were, comforting your baby through sleepless nights, soothing her with a dentist-approved teether, celebrating as that first tiny tooth poked through her gums. And now here she is running to show you that same tooth, wiggly, loose, and almost ready for the Tooth Fairy. Now what?

Be Prepared

Children normally lose that first tooth somewhere around the age of six, but a year or two earlier or later is not uncommon. If you ever took a business class, you might have heard of the inventory method called “First In, First Out.” Baby teeth operate much the same way! The two bottom front teeth, followed by the two upper front teeth, will probably be the first teeth your child loses. Once you notice some wiggling, let your child know what is going on and reassure her that it is a normal part of growing up.

What to Expect with that First Loose Tooth

Normally, baby teeth become loose when the pressure from the permanent tooth below gradually breaks down the roots of the primary tooth. If your child has a loose tooth, encourage him to wiggle, not pull. Typically, gentle wiggling is all that is needed to free a tooth that has lost most of its root and is ready to be replaced. Avoid pulling or forcing the tooth, because that can cause injury to the root area if the baby tooth isn’t ready to come out. Call our Issaquah office if you have any questions about loose teeth. Drs. Arti and Ashi and our team also have suggestions if the baby teeth don’t become loose on schedule, or if they stubbornly remain in place even after the adult teeth have started to show up. One important note—if your child ever loses a tooth through accident or injury, call us at once. We might need to provide a spacer to give your child’s permanent teeth the proper time and space to come in.

Celebrate this Milestone with Your Child

The arrival of the Tooth Fairy is a familiar way to mark the occasion, and she can leave your child a note, a small gift, even a brand new toothbrush. Or explore other options!

If your child is fascinated by stories and traditions, learn about El Ratón Pérez (Perez the Mouse), a familiar tooth-collector in many Spanish speaking countries, or his French cousin, La Petite Souris (the Little Mouse). In other parts of Europe, Asia and Africa, children throw teeth on the roof, drop them in a glass of water, or hide them in a slipper. This is a great opportunity for you and your child to explore the world!

If your child likes science, look into books that explain the biology of baby and adult teeth in an age-appropriate way. You could print a chart of the primary teeth and take notes on each lost tooth as it makes way for the permanent tooth below. Or track her progress with photos showing the baby tooth, the gap left by the tooth, and the adult tooth as it comes in.

Losing that first tooth is an important moment for your child—and for you. Be prepared to celebrate another milestone together, and always feel free to talk to Drs. Arti and Ashi if you have any questions about this new stage in your child’s life.
