Ask Us about These Dental Treatments

March 11th, 2026

There are a few dental treatments that Dr. John Zarrella and Dr. Peter C. Rider and our team recommend for all patients to get if they wish to protect their oral health. Sometimes it’s hard for patients to decide which treatment plan would be best for their teeth. Learn about these three must-have treatments and how they can help protect your teeth in various ways.

Professional Cleanings

First, get a professional dental cleaning every six months. Regular cleanings can protect you from potential gum disease because they enable us to catch it early.

Cleanings also will get rid of plaque and tartar that have collected on your teeth over time. Oral health has been linked to your body’s overall health. We recommend scheduling your appointments in advance: Feel free to contact our practice’s Ashland location if you forget when you scheduled your next visit. Our staff will be happy to assist you.

Periodontal Exams

We also recommend that all our patients at Zarrella Dentistry receive a complete periodontal exam each year. You can ask about this during your regular, scheduled cleanings.

It’s a quick and painless procedure in which our hygienist probes each tooth to make sure the bone and soft tissue are healthy. If there’s a sign of infection, we will be able to treat it effectively before painful symptoms kick in.

Many adult patients are unaware that they have periodontal disease, and they may suffer the loss of a tooth if it goes untreated. Make sure you schedule a periodontal exam each year and save yourself a lot of time and pain.

Sealants

We also recommend dental sealants, particularly to protect your molars. Many people assume this treatment is just for kids to prevent cavities, but it can be used for adults too!

Sealants provide a protective barrier on your teeth that can help block against the buildup of plaque in those hard-to-reach areas in the back of your mouth. If you received sealants as a child, chances are they’ve worn off over time.

So if you want to save dental costs over the long haul, we recommend getting sealants again for cavity protection.

Dr. John Zarrella and Dr. Peter C. Rider and our team hope you take our advice when it comes to your oral hygiene and schedule regular appointments for your dental cleanings. We look forward to seeing you at your next appointment!

Getting to the Bottom of Chewing Gum Myths

March 4th, 2026

It's a moment many of our patients have experienced. One second you're chewing on a piece of gum, then suddenly you forget to keep chewing and swallow the entire rubbery gob whole! It's at this point you remember your mother warning you as a child that if you swallow gum it will stake a claim and take up residency in your belly for seven years. Dr. John Zarrella and Dr. Peter C. Rider and our team at Zarrella Dentistry hate to take all the fun out of the mystery, but the truth is that chewing gum, when swallowed, will enter your stomach and move through your digestive system just like any other piece of food. So, if you ever accidentally swallow a piece of gum, there is no need to worry!

That being said, it's important to know that gum does not have any dietary benefits, so while it’s not exactly harmful to swallow, you still want to avoid swallowing it. If you are an avid gum-chewer, we encourage you to chew sugarless gum, especially if you are wearing braces, because gum with sugar can lead to cavities. Sugarless gum still has the same amount of flavor, but has fewer cavity-causing ingredients. In fact, many brands contain an additive called xylitol, a natural sweetener known to fight cavity-causing bacteria. Xylitol is also known to increase salivary flow as it rinses away plaque and acid.

The fact is, when the bacterium in your mouth breaks down sugar, what’s left behind is acid. This acid eats away at the enamel coating of your teeth, causing holes that we call cavities. Cavities can lead to other long-term mouth problems if they are not treated in time, so it is best to try and avoid overexposing your teeth to too many harmful substances!

If you have any questions about chewing gum, please contact our office. Happy (sugar-free) gum chewing!

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.
