October Is Orthodontic Health Month!

October 7th, 2026

October’s here! A month when we celebrate the beauty of fall, the taste of pumpkin spice, the fun of Halloween in Ashland, and the healthy smiles which orthodontic treatment makes possible!

Because October is Orthodontic Health Month, and it’s a great time to talk about how your orthodontist helps you create not just a more beautiful smile, but a healthier one. 

Straight, evenly spaced teeth are the visible benefit of treatment, but there are many health benefits which might not be quite as noticeable. Orthodontic treatment can:

  • Help You Prevent Cavities and Gum Disease 

When teeth are crowded or crooked, it’s hard for your toothbrush and floss to reach all of the plaque which builds up on and between your teeth. The bacteria in plaque create acids which start to dissolve tooth enamel. And a very small hole in the enamel surface can grow until it becomes a cavity. 

Plaque and bacteria also irritate the gums. When you can’t remove plaque completely, your gums are at risk for gingivitis. This early stage of gum disease causes redness, tenderness, swelling, and bleeding. Left untreated, gingivitis can develop into more serious gum disease. 

And, over time, plaque hardens and becomes tartar, which needs to be removed professionally at Zarrella Dentistry.

When your teeth are straight and evenly spaced, brushing and flossing are both easier and more effective, helping you keep your teeth and gums healthy and plaque-free.

  • Create a Better Bite

For a healthy bite, your teeth and jaws need to align correctly. The top teeth should slightly overlap the lower teeth, and the ridges of your upper molars should fit smoothly with the grooves of your lower molars. 

Malocclusions, or bad bites, can come in many forms, including overbites, underbites, open bites, cross bites, and overjets. A bad bite is bad for your dental health. Malocclusions can cause tooth grinding, worn enamel, and even cracked teeth. 

And bad bites don’t just affect your teeth. When your bite doesn’t align properly, you might suffer from problems such as headaches, jaw pain, indigestion, and sleep apnea. 

Orthodontic treatment creates a healthy, symmetrical, and pain-free bite.

  • Improve Your Self-Confidence

We can’t forget the invisible health benefits of orthodontic treatment! Your smile is a gift which you share with the world. But if you’re hesitating to smile because of self-consciousness about your teeth or bite, orthodontic treatment can make a world of difference.

Your orthodontist can help you achieve straighter teeth, a bite which fits together properly, and, when malocclusions affect jaw symmetry, a more balanced facial profile. If you’re concerned about the appearance of your smile, talk to Dr. John Zarrella and Dr. Peter C. Rider about an orthodontic consultation. Today’s technology can even let you see what your future smile will look like!

Modern orthodontic treatment is more effective and takes less time to complete than ever before. And orthodontics offers patients of all ages more benefits than ever before: 

  • New types of braces are less noticeable and more comfortable than older styles. Smaller brackets, brackets which blend with tooth enamel, clear aligners, and lingual braces give you a variety of options to customize your treatment.
  • Early orthodontic treatment can guide jaw growth in younger children. 
  • Appliances can help with jaw alignment in older children, or, for more serious malocclusions, an orthodontist can coordinate treatment with an oral surgeon.
  • Treatment isn’t limited to the teen years. Adults make up a large and growing number of orthodontic patients. 

If you’ve been considering orthodontic treatment, October—or any month!—is a great time to schedule a visit with an orthodontist. An orthodontic evaluation will let you know just what your orthodontist can do to help you create a beautiful and healthy smile.

Healthy Gum, Healthy Mouth

September 30th, 2026

“Shouldn’t that be healthy gums,” you’re thinking? And, of course, you’re correct. Healthy gums are extremely important not only for our dental well-being, but for our overall physical health.

But that’s a subject for another blog! Today, we’re talking about healthy gum—chewing gum, that is. Because choosing the right chewing gum can actually improve your dental health.

Oral bacteria use the foods we eat, especially sugars and simple carbs, as fuel to produce acid. These acids attack our tooth enamel, gradually weakening the minerals in the tooth surface and allowing cavities to develop. Clearly, we want to reduce these acids to help prevent decay. Luckily, our bodies have a natural defense against acid attacks—saliva.

Saliva works to protect our enamel in three ways:

  • It helps neutralize and wash away acids in the mouth.
  • It rinses away the food particles which bacteria feed on.
  • It strengthens teeth by providing the necessary minerals our enamel needs to “remineralize” after acids have weakened the tooth surface.

Studies have concluded that chewing sugarless gum for 20 minute after a meal can help prevent cavities. Why? Because chewing gum increases saliva production. You are actually reducing the effects of harmful acids, washing food particles away from your teeth, and strengthening weakened enamel with every stick! Some artificial sweeteners are even thought to inhibit the growth of the bacteria that lead to decay.

With all that in mind, it’s also healthy to know when you shouldn’t chew gum:

  • When the gum contains sugar. Even with an increase in saliva production, bathing your teeth in sugar as you chew does your enamel no favors!
  • When you wear braces. Gum can stick to your brackets and between your brackets and your wires. And while trying to clean gum from your appliance is no one’s idea of fun, an even more unpleasant possibility is the chance that gum might bend your wires out of shape. Sugarless gum is not quite as sticky as regular gum, but before you open that first pack, check with your orthodontist to see if you might be putting your orthodontic work at risk.
  • When you have jaw problems such as TMD, TMJ or other temporomandibular concerns, or if you develop jaw pain while chewing gum.
  • You should never give gum to a child too young to understand that it should not be swallowed. Beyond acting as a choking hazard, continual gum swallowing can lead to diarrhea, blockages, abdominal pain and other serious problems. Talk to your Dr. John Zarrella and Dr. Peter C. Rider about the right age for chewing gum.

While chewing sugarless gum has the potential to improve dental health, remember it should never take the place of regular brushing and flossing—still the best way to prevent cavities at home. Talk to Dr. John Zarrella and Dr. Peter C. Rider about the possible benefits of sugarless gum at your next visit to our Ashland office, and we can make recommendations based on your individual dental history. Because whether it’s healthy gums or healthy gum, we’re here to help.

What to Do When the Tooth Fairy Isn’t on Schedule

August 5th, 2026

August 22 is National Tooth Fairy Day! If the Tooth Fairy is a treasured part of your child’s life, you’re just in time to celebrate! But what to do when the Tooth Fairy doesn’t arrive on schedule—when baby teeth stay longer than expected or are lost too soon? 

A baby’s 20 baby teeth tend to come in within a fairly predictable time frame. The bottom central incisors in the very front of your baby’s mouth typically make their appearance first, when your baby is around six to ten months old. Over the next few years, the remaining incisors, canines, and first molars arrive. Last on the scene are the second molars, which usually show up between the ages of 23-33 months. 

Just as baby teeth follow a pattern coming in, they tend to follow the same pattern falling out. The front teeth begin to wiggle and loosen around age six or seven, while the last of the baby teeth, the canines and second molars, are often lost between the ages of ten and 12. 

Baby teeth fall out as the adult teeth below them push up as they erupt. The top of the new tooth puts pressure on the root of the baby tooth, gradually dissolving it. As the root grows smaller and can’t anchor the tooth, the tooth begins to wiggle and eventually becomes loose enough to fall out. This leaves the adult tooth perfectly placed to grow into its proper position.

Sometimes, though, teeth linger far past their fall-out date. Sometimes, because of decay or trauma, they are lost much too early. In either case, Dr. John Zarrella and Dr. Peter C. Rider can provide treatment to protect little smiles now and to ensure that there’s space for the permanent teeth to erupt and align correctly.

Teeth Which Overstay Their Welcome

If that baby tooth never gets wiggly, the team at Zarrella Dentistry can help! When baby teeth stubbornly hang on, adult teeth can erupt behind them, creating a double row of teeth commonly known as “shark teeth.” These permanent teeth can become crowded or misaligned as they try to fit in any space available. Or a baby tooth can block an adult tooth from erupting at all. When that baby tooth just isn’t budging, an extraction will create space for the permanent tooth to erupt.

Extracting a baby tooth is generally a straightforward procedure because primary teeth have very small roots. Your child’s dental team at Zarrella Dentistry are experts in helping you prepare your child for the procedure in a gentle, reassuring, and age-appropriate way. 

Often, a local anesthetic is all that’s necessary for a simple extraction, but if you feel sedation would better fit your child’s needs, discuss sedation options with your dentist. After the extraction, you’ll be given clear information on how to deal with pain and swelling, which foods and drinks are best while the extraction site heals, and how to protect the area.

Teeth Which Exit Too Early

In the case of decay or trauma, Dr. John Zarrella and Dr. Peter C. Rider will do everything possible to save the tooth. When decay is so extensive that there’s not enough structure left to hold a filling or crown, or when there’s an infection in or around the tooth, or when an accident or injury has caused serious damage, extraction might be the healthiest option. Depending on your child’s age, further treatment might be needed afterward to protect future smiles. 

Besides their roles in eating and speaking, baby teeth save space for permanent teeth. Whenever a child loses a primary tooth too soon, the family dentist will be on the lookout for potential future orthodontic problems. If remaining baby teeth shift, taking up part of the empty space left behind by the lost tooth, the adult teeth below won’t have the space they need to erupt properly. Permanent teeth might come in at an awkward angle or in the wrong place. 

In this case, Dr. John Zarrella and Dr. Peter C. Rider might recommend a space maintainer. Space maintainers are small, custom-designed appliances which prevent the remaining baby teeth from shifting position while holding space open for the permanent tooth to arrive right on schedule and right where it belongs. 

It’s comforting to have charts which let us know when little teeth will typically come in and when they will typically fall out. But unexpected events might mean teeth overstay their welcome or depart too soon. When the Tooth Fairy can’t keep to her schedule, schedule an appointment at Zarrella Dentistry in Ashland as soon as possible to make sure your child is on track for a future of healthy smiles.

Oral Cancer

July 29th, 2026

Dr. John Zarrella and Dr. Peter C. Rider and our team want you to have the healthiest possible smile in the healthiest possible body. Oral cancer can affect the mouth, tongue, throat and jaw. Early detection is vital for the best possible outcome when treating this disease. That is why we check for symptoms of oral cancer at every dental examination.

What can you do to reduce the chance of oral cancer?  Reduce your risk factors. You can help prevent oral cancer by adopting these healthy habits:

  • Don’t smoke. Don’t chew tobacco. Don’t use a pipe. If you use any tobacco products, quit. Tobacco use is the single largest risk factor for head and neck cancers. Talk to us—we have suggestions for helping you break the habit.
  • Drink alcohol in moderation. Heavy drinkers have a higher rate of oral cancer. More than one to two drinks per day can be considered heavy drinking, depending on factors such as weight, age, and even gender. Check with your doctor to find your personal definition of moderation.
  • Eat a healthy diet. Cancer-fighting fruits and vegetables are a great addition to any menu.
  • Protect yourself from the sun. Help prevent sun-related lip cancers by always wearing a UVA/UVB blocking sun screen or lip balm whenever you are working or playing outside—and reapply frequently.
  • Some forms of the HPV virus have been linked to oral cancer, and those affected are generally younger and less likely to be smokers. Research indicates that the HPV vaccine, known for preventing several types of cancer, might also help prevent HPV-related oral cancers.
  • Schedule regular dental exams. We are trained to recognize oral cancer and precancerous conditions that you might miss.

Of course, cancer can occur even with the healthiest habits. Do come see us if you detect any of these symptoms:

  • A sore or ulcer that doesn’t heal, or persistent tenderness and pain in the mouth
  • Lingering sore throat, hoarseness, or vocal changes
  • Pain in the neck or ear that doesn’t go away
  • A lump, a rough or thickened area, or eroded tissue in the skin lining the mouth
  • Red or white patches in the lining of the mouth or on the tongue
  • Difficulties chewing, swallowing, speaking, or moving the tongue or jaw
  • Numbness in the tongue or mouth
  • Changes in the way your natural teeth or your dentures fit together.

Not every symptom is caused by cancer, but it is important to rule out the possibility. We are trained to recognize early signs of oral cancer, and can recommend further tests if needed. Call our Ashland office immediately if you have any concerns. Early detection and treatment lead to the most successful outcomes.
