Is Coffee Damaging Your Smile?

November 19th, 2025

Coffee is one of the most popular drinks in the world. Many people have a cup, or two, or even three a day. It’s common to drink it in the morning to wake up and get ready for the day, as an afternoon pick-me-up, or just to catch up with a coworker or friend.

These days there are many different kinds of coffee flavors to enjoy, so it’s almost impossible for a person not to like it. But as delicious as coffee is, it’s worthwhile to be aware of the effects it has on our dental health.

Coffee contains a lot of tannic acid, which is what causes its dark color. Tannic acid ingrains itself into the grooves of tooth enamel, and that leads to serious stains. In addition to containing tannic acid, the fact that coffee is generally served very hot makes your teeth expand and contract, which allows the stains to penetrate even farther into the enamel.

Dr. John Zarrella and Dr. Peter C. Rider and our team know it’s not easy to kick the caffeine habit. If you find yourself needing a cup of joe every day, here are some helpful tips to consider:

  • Switch to decaf coffee.
  • Make it a habit to drink a glass of water with your coffee to rinse away the acid.
  • Try enjoying your coffee with a straw so the tannic acid makes less contact with your front and lower teeth.
  • Pop in a piece of gum after your coffee to help prevent a dry mouth.

If you’re feeling ambitious, you might find that setting a limit on the number of cups of coffee you have per week or even per day can be helpful. You are always welcome to contact our Ashland office to discuss potential whitening options as well. We’re here to help!

What is a cavity?

November 12th, 2025

Cavities are the reason why most people fear going to the dentist. But they’re also the reason you should be visiting Dr. John Zarrella and Dr. Peter C. Rider on a regular basis.

Specifically, cavities are the breakdown of teeth caused by acid from food, bacteria, and plaque that inhabit the inside of the mouth. While many people simply think that cavities only form on top of a tooth, Dr. John Zarrella and Dr. Peter C. Rider and our team at Zarrella Dentistry want you to know they can actually form on the sides along the gum line and between the teeth, too. This acid will eat away at the tooth, forming a soft hole.

Anybody, either children and adults, can get cavities. In fact, according to the Centers for Disease Control and Prevention, in the U.S. alone about 16 percent of all children ages six to 19 have untreated cavities, and about 24 percent of adults 20 to 64 years old have them. This is detrimental to overall oral health, because cavities have a tendency to grow over time, potentially spreading to other teeth and causing increased oral pain, possibly even affecting the nerve.

That's why it's important to ensure that you're visiting Zarrella Dentistry at least once every six months, so that cavities can be found and filled before they become too problematic and painful. Typically, they're found by doing a routine teeth cleaning, though X-rays or further examination may be necessary to determine the full extent of a cavity. Cavities are treated by removing the area of the tooth where decay has set in and rebuilding the tooth with a metal filling. If the cavity is too large, however, more extreme measures may be necessary, such as placing a crown or performing a root canal.

As we noted above, cavities are why people dread going to the dentist, but also the reason everyone should see the dentist every six months. Additionally, brushing twice daily, flossing, and cutting down on sugar-packed foods can reduce the risk of developing cavities.

Tips for Cold and Flu Season

November 6th, 2025

It’s peak cold and flu season, a time to be especially conscious about your health. We have some suggestions to help you navigate this contagious time of year, with bonus tips for a healthy smile.

  • Wash Up! 

Bacteria and viruses can live for hours and even days on non-porous surfaces like doorknobs, phones, and keyboards. That’s why it’s so important to wash your hands before touching your mouth, nose, and eyes, before brushing and flossing, and before you cook or eat. Washing with plain soap and water will eliminate most germs.

Bonus Tip: Keeping your fingers away from your mouth does more than prevent the transmission of bacteria and viruses. Fingernail biting can damage enamel. Prolonged thumb or finger sucking can affect tooth and jaw alignment. Delicate gum tissue can be injured or infected by broken or dirty fingernails. If you’d like to break harmful oral habits, talk to Dr. John Zarrella and Dr. Peter C. Rider for suggestions.

  • Stay Hydrated

Hydration supports healthy skin, helps regulate blood pressure and body temperature, and is vital for digestion and other bodily functions. Proper hydration is also important for a healthy immune system and healthy mucous membranes, which will help you fight off colds and flu. Talk to your doctor about your ideal amount of daily hydration, whether from water, other fluids, or water-rich foods.

Bonus Tip: We also need to be hydrated to produce healthy levels of saliva. Saliva washes away food particles and bacteria and helps neutralize enamel-eroding acidity in the mouth.

  • Eat Healthy Foods

A healthy diet is crucial for a healthy immune system, with foods such as lean proteins, fruits, vegetables, whole grains, and low-fat dairy products.

Bonus Tip: A balanced diet is good for your oral health, too! We need vitamins A and C for healthy gums and oral tissues, minerals like calcium and phosphorus to keep tooth enamel strong, and dairy products enriched with vitamin D, which enables our bodies to absorb the calcium we get in our diet.

What happens if you become ill despite your precautions? 

  • Reduce the Chance of Infecting Others

If you’re ill, you can help stop the spread of germs by limiting contact with other people, covering your mouth and nose when you cough or sneeze, washing your hands frequently, and cleaning the common surfaces in your house which harbor germs. 

Bonus Tip: Sharing isn’t caring when it comes to colds and flu. No matter how close you are to your family members or roommates, your toothbrushes shouldn’t be close at all. Let your brush air-dry in an upright position away from other brushes to avoid contamination. 

  • Be Choosy about OTC Medications

If you take sugary cough or cold medications, brush or rinse afterward. Sugar-free cough drops are better for your teeth than sweet lozenges which bathe your enamel in sugar as you let them dissolve. 

Bonus Tip: Don’t bite into cough drops! You risk chipping or cracking a tooth.

  • Keep Up with Healthy Habits

Be sure to keep hydrated, especially if you’ve been suffering from vomiting or diarrhea. Get the sleep you need to recover. Eat a well-balanced diet.

Bonus Tip: Stay on top of your dental hygiene and brush and floss as usual, with one caution. Vomiting brings up harsh stomach acids which weaken the mineral bonds keeping tooth enamel strong, so brushing right away can be abrasive. If you throw up, rinse your mouth with water and wait 30 minutes before brushing to allow your enamel to come back to full strength.

  • Stay Home When You’re Sick

You’ll get better faster with proper care, which includes getting the rest you need to recover. And you won’t be sharing germs with the people around you.

Bonus Tip: If you have an appointment scheduled with your dentist, reschedule if necessary. Your dental team at Zarrella Dentistry will be happy to accommodate you to prevent the spread of germs and to make your dental procedure a more comfortable one.

It’s the height of cold and flu season in Ashland, but you’re not alone! Talk to your doctor about immunizations and other preventative measures. If you do become ill, follow your physician’s recommendations. And if you have any dental concerns, your dental team is prepared with timely advice—at any time of year.

Let’s Make Halloween Treats Less Tricky!

October 29th, 2025

If the scariest part of Halloween in Ashland is trying to figure out which treats are braces-friendly and which treats are braces-frightful, we have a fiendishly simple suggestion to help keep your brackets and wires safe from harm: ghost any treats which are chewy, crunchy, hard, or sticky!

It’s no mystery how certain candies and treats can cause trouble for your braces. The pulling effect of chewy candies like caramels can pull a bracket right off your tooth. Biting into a hard candy can break a wire. Crunchy treats can get stuck under wires and damage braces. Sticky foods pull on your wires and brackets.

Broken braces are no fun. Loose or detached brackets can be uncomfortable. Bent or broken wires can cause sores and cuts inside your mouth. Damaged braces mean extra trips to the orthodontist for repairs, and can even delay your treatment if the damage is significant or you can’t see your orthodontist right away. 

And chewy, crunchy, hard, and sticky treats have a haunting effect on your dental health as well. These foods stick to brackets and wires and can be difficult to brush or floss away. Cavity-causing bacteria feast on the sugars and food particles left behind, putting you at greater risk for cavities.

So, what specific treats should *vanish* from your candy collection this Halloween? Here are some of the most damaging to braces: 

  • Chewy caramels, taffy, fruit chews, gum, and licorice
  • Crunchy candied apples, caramel popcorn, peanut brittle, nuts, and popcorn balls 
  • Hard and hard-shelled candies, lollipops (especially with gum centers), and jawbreakers
  • Sticky gummies, jellybeans, and candy corn

But it’s not all frightful news! There are many spook-tacularly good treats which you can enjoy without putting your braces in jeopardy:

  • Peanut butter cups
  • Soft chocolate bars (with no nuts or caramel hiding inside!)
  • Soft cupcakes
  • Pudding cups
  • Mint patties
  • Ice cream
  • Sugar-free gum (if it’s okay with Dr. John Zarrella and Dr. Peter C. Rider and your orthodontist)

And here are a few good tricks for keeping your teeth and gums healthy, whether or not you wear braces:

  • Brush and floss after treats. 
  • Enjoy sweets in moderation. 
  • Skip the sour candies. Acidic foods can damage tooth enamel.
  • Eat treats with a meal. Eating increases saliva production, which helps neutralize acids and wash away food particles.

Don’t let a damaged bracket or wire spoil your Halloween fun. Talk to the team at Zarrella Dentistry to learn which candies are a treat for both you and your braces and you’ll stay on the fast track to a boo-tiful, healthy smile!
