Top Five Dental Myths

February 25th, 2026

Sometimes the line between fact and fiction is easily blurred. This is certainly the case when it comes to dentistry, where myths and misconceptions abound. In a bid to put an end to health hoaxes, here are five dental myths to chew over.

Sugar Is the Number One Culprit of Tooth Decay

Sugar will rot your teeth. If you’re a parent, chances are you tell your children this every time they ask for something sweet. And chances are your parents told you the same thing. There’s no denying that sugar leads to cavity formation, but it's not the number one culprit of tooth decay. Sugar adds fuel to the fire, but it doesn’t light the match.

Going to the Dentist Is a Painful Experience

There are people who don’t go to the dentist because they think it’s going to be a painful experience. It’s time to put this myth to rest. New dental technology, developments in anesthetics and analgesics, and more conservative dental procedures have made visits to our Ashland office a more comfortable experience.

Bad Breath Means You’re Not Brushing

Poor dental hygiene can cause bad breath, but it’s not the only thing that will leave you looking for a breath mint. There are many factors that can cause bad breath, including illness, acid reflux, medication, and dehydration. In addition, sometimes what you eat or drink can give you bad breath no matter how many times you brush and floss. Next time you order a sub for lunch, skip the onions and garlic.

Bleaching Products Weaken Teeth

Gels, pastes, strips — there are all sorts of products available to make our pearly whites even whiter. If used according to the directions, bleaching products are harmless. They do not affect the health or strength of the teeth, only the color. At the same time, too much bleaching can cause temporary tooth sensitivity or irritated gums; the enamel, however, is not weakened.

You Will Know When You Have Tooth Decay

This is the type of false information that can lead to serious dental problems. There are no early symptoms of tooth decay. By the time you experience pain, your tooth decay has led to nerve damage, which means your decay is advanced and extensive. The only way to know if you have tooth decay —and to prevent it — is to visit Dr. John Zarrella and Dr. Peter C. Rider twice a year for a checkup and cleaning.

Mall Whitening: Why You Shouldn’t

February 18th, 2026

A shopping mall is a great place to get lots of errands done in one trip. Department stores, clothing boutiques, specialty shops? So many tempting options all in one place. But teeth whitening? Maybe not.

Dental office whitening provides you with the whitest possible teeth in the safest possible manner. Your teeth will be checked first for any conditions that might make whitening a bad idea, such as tooth decay, weakened enamel, or gum disease. Dr. John Zarrella and Dr. Peter C. Rider will make sure your gums and mouth are protected. A gel with a higher concentration of bleaching agents than those available over-the-counter will be applied, and your whitening progress will be monitored. You can also ask about having a custom-fitted tray made for at use at home with professional whitening gel.

What is different about mall bleaching?

  • No dental exam will be provided beforehand. If you have dental issues, the whitening process might cause further problems such as tooth sensitivity or gum inflammation.
  • The amount of peroxide in the bleaching agents can vary from place to place. You might end up with something equivalent to home whitening strips, or you might be exposed to solutions that should only be available in a dentist’s office.
  • Finally, in many areas, mall whitening is actually illegal because it is considered the practice of dentistry without a license. Mall kiosks skirt this problem by having customers insert the trays full of gel themselves—a practice that does not take the place of professional training, licensing, and regulation.

A mall kiosk is a convenient place to select a new phone. Or try an unusual hair care product. Or purchase the latest in fad toys. But when it comes to your dental health, it’s worth a special trip to our Ashland office if you want the safest, most effective whitening.

The Origins of Valentine's Day

February 11th, 2026

When we think of Valentine’s Day, we think of cards, flowers, and chocolates. We think of girlfriends celebrating being single together and couples celebrating their relationship. We think of all things pink and red taking over every pharmacy and grocery store imaginable. But what Dr. John Zarrella and Dr. Peter C. Rider and our team would like to think of is when and how this joyous, love-filled day began.

Several martyrs’ stories are associated with the origins of Valentine’s Day. One of the most widely known suggests that Valentine was a Roman priest who went against the law at a time when marriage had been banned for young men. He continued to perform marriage ceremonies for young lovers in secret and when he was discovered, he was sentenced to death.

Another tale claims that Valentine was killed for helping Christians escape from Roman prisons. Yet another says that Valentine himself sent the first valentine when he fell in love with a girl and sent her a letter and signed it, “From your Valentine.”

Other claims suggest that it all began when Geoffrey Chaucer, an Englishman often referred to as the father of English literature, wrote a poem that was the first to connect St. Valentine to romance. From there, it evolved into a day when lovers would express their feelings for each other. Cue the flowers, sweets, and cards!

Regardless of where the holiday came from, these stories all have one thing in common: They celebrate the love we are capable of as human beings. And though that’s largely in a romantic spirit these days, it doesn’t have to be. You could celebrate love for a sister, a friend, a parent, even a pet.

We hope all our patients know how much we love them! Wishing you all a very happy Valentine’s Day from the team at Zarrella Dentistry!

February Is Children’s Dental Health Month

February 4th, 2026

It’s the littlest month of the year, so what better time to think about the dental health of our littlest family members? February is National Children’s Dental Health Month, and we’re here to suggest some of the best dental habits for healthy childhood smiles.

Babies 

  • Even before your baby cuts her first adorable tooth, you can start proactive dental care by gently wiping little gums with a clean, moist gauze pad or soft cloth twice a day. This removes bacteria and food particles and helps prepare your baby for brushing.
  • When that first tooth does appear, or by age one if it hasn’t yet erupted, it’s time to schedule a visit to the dentist. At this first visit, your child’s dentist will check jaw and tooth development and can give expert guidance on teething, brushing, how much and which kind of toothpaste to use, and topics like thumb-sucking and pacifier use.
  • When baby teeth arrive, use a small soft-bristled toothbrush designed to fit comfortably in tiny mouths.
  • Use toothpaste as recommended. Children under the age of three who use paste should use a very small amount, no larger than a grain of rice.
  • Prevent “baby bottle tooth decay”—don’t put your baby to bed with a bottle. This allows the sugars in formula or, when your child is 12 months or older, milk, to bathe the teeth throughout the night. And babies and toddlers never need sugary juices or sodas in those bottles!

Toddlers 

  • Help your child develop a positive relationship with his dental team. Read books or watch videos to help your child learn what to expect. Practice with him by having him open his mouth while you count his teeth. Plan visits when your child isn’t hungry or tired. Be positive yourself—your child will take his cues from you!
  • Schedule regular appointments for exams and cleanings. Dr. John Zarrella and Dr. Peter C. Rider will check tooth and jaw development, look for any signs of decay, and evaluate potential problems such as prolonged thumb sucking or pacifier use. 
  • By age three, children have most or all of their baby teeth. Use a soft bristled brush to clean your child’s teeth twice each day. As she grows, demonstrate how to brush properly. The dental team at Zarrella Dentistry will have some great ideas on technique!
  • Daily flossing should begin as soon as your child has two teeth which touch. 
  • Around age six, your child may be transitioning to solo brushing and flossing—but your oversight is still needed. Make sure all the surfaces of the teeth, including the tops of new molars, are brushed thoroughly. You might provide a timer or a two-minute song or video to make sure your child spends enough time brushing. Flossing can be tricky for young hands, so you’ll need to help with that task for a few years more.

School-Aged Children

  • Dentists and orthodontists recommend a first visit to the orthodontist by age seven, or earlier if you notice your child has trouble chewing or biting, if the teeth don’t seem to fit together properly, or if you have any concerns about bite and alignment. When potential problems are discovered right away, early intervention can prevent more serious orthodontic issues from developing later. The team at Zarrella Dentistry in Ashland is happy to answer any questions you might have about early interventions!
  • Talk to Dr. John Zarrella and Dr. Peter C. Rider about sealants. Permanent molars usually erupt between the ages of 6 and 12. Sealants are thin coatings which protect the chewing surfaces of these molars from food particles and cavity-causing bacteria which would otherwise collect inside grooves in the enamel.
  • Children who play sports and engage in activities with a chance of physical contact should have a well-fitted mouthguard to protect their teeth. Be ready to replace it as often as recommended by Dr. John Zarrella and Dr. Peter C. Rider or if it’s damaged.
  • Increases in hormones during puberty can lead to puberty gingivitis, and swollen, red, and bleeding gums can be the result. Proactive dental hygiene will prevent gum disease from developing. Make sure your child brushes two minutes, twice a day, and flosses once per day. If symptoms persist, it’s time to see the dentist.
  • If your child is beginning orthodontic treatment, you can help make the journey easier. Keep up with appointments and adjustments, look for toothbrushes and floss designed for braces, and provide braces-friendly foods. If your child wears bands or aligners, you may need to remind her to wear them for the recommended number of hours each day. 
  • A nutritious diet is essential for healthy teeth and gums. Give your child solid nutritional building blocks with a diet rich in proteins, vitamins, and minerals. 

Help your child enjoy a future of healthy, confident smiles by working in partnership with your child’s dental team. They are ready every month of the year with advice and expertise to make that healthy dental future a reality!
