Your Hard-Working Teeth

July 22nd, 2026

Healthy teeth make you happy to share your smile with the world. But there’s more to your smile than its beauty! There’s a lot of hard work going on, as well.

Teeth Are Designed for Healthy Eating and Digestion

Because humans are omnivores, we can eat both meat and plants. That’s why our teeth have different shapes—they’re designed to help us process different types of food. 

  • Incisors, our front teeth, have sharpish edges to help cut through meats and other firm foods when we bite.
  • Canines, the pointed teeth, help tear food into bite-size portions.
  • Premolars are flat topped teeth with two cusps, raised points which help grind food.
  • Molars are the flat-topped teeth in the rear of the mouth. They have four cusps to grind and crush food into a paste-like consistency. 

So: Incisors and canines bite and tear food into smaller pieces, which molars and premolars then crush and grind into a paste. Bite, tear, crush, grind—why all this food aggression? Because that’s the key to healthy digestion! 

Chewing is the first step in digestion. Effective chewing:

  • Starts the process of breaking food down into digestible particles.
  • Increases saliva production. Saliva binds food particles so that we can swallow easily.
  • Expands the surface area of food particles, which allows the digestive system to extract nutrients more efficiently. 

When you’ve lost teeth or biting causes you pain, it can be hard to chew food as thoroughly as you should. Swallowing can be difficult. Digestion can suffer. In fact, healthy teeth are essential to healthy digestion. 

Teeth Have Other Important Jobs As Well

  • Speaking

Our teeth work with our tongues and lips to form many of the phonetic sounds which make up speech. Missing or misaligned teeth can affect speech development in children and pronunciation in children and adults.

  • Creating a Healthy Bite

To eat efficiently—and comfortably—we need a healthy bite. If your dentist or orthodontist has diagnosed a malocclusion, it means that your teeth don’t fit together properly because of misaligned teeth and/or jaws. Biting and chewing put hundreds of pounds of pressure on your teeth and jaws, and a bad bite can mean damaged teeth and painful jaw problems. 

  • Shaping the Face

Just like our bone structure, our teeth help give shape to our faces. Missing teeth can affect the appearance of chins, lips, and cheeks. Replacing lost teeth with dentures, bridges, or implants (which look and function like natural teeth) can restore facial symmetry.

Teeth Are Only Up to the Job with Your Help

You’re in charge! Daily brushing and flossing, eating a healthy diet, and regular visits to your dentist for exams and cleanings will help make sure your teeth are able to perform their many duties. 

If you’re experiencing tooth pain, if you have concerns about alignment, or if you’ve lost a tooth or teeth, talk to your dentist to learn how to get your teeth back to working their best for you—and be ready to share that beautiful, hard-working smile!

Be Prepared!

July 15th, 2026

When you’re busy at work or school, when you’re on vacation, when you’re on the road to adventure—preparation helps everything go smoothly. Especially when the unexpected happens! So, how can you be prepared for any dental situations which might arise? By creating these useful—and portable—travel kits.

Everyday Basics Kit

Dr. John Zarrella and Dr. Peter C. Rider and our team recommend brushing twice a day and flossing at least once each day for clean and healthy teeth. But after a long day at work with no time to head home before your date, or a garlic-heavy lunch, or a morning filled with coffee and pastries to help you meet a deadline, you might feel like there’s no time like the present to give your smile a bit of a boost.

Be prepared with a small travel bag filled with these easy-to-carry basics to get you through your busy day with clean teeth, fresh breath, and a confident smile:

  • Toothbrush and case—and do make sure your case is ventilated so your brush can air dry. Bacteria love a closed, damp environment!
  • Toothpaste
  • Mini-bottle of mouthwash
  • Small mirror—to check for any lunch leftovers
  • Dental floss—to remove any lunch leftovers
  • Dental picks
  • Sugarless gum—to freshen your breath and encourage saliva production, which helps clean away bacteria and food particles

Flight Gear

Getting set to travel by air again after this long lay-over? Your basic kit will do the job with just a few minor additions and alterations.

  • A travel version of your manual or electric toothbrush and travel case
  • Plug adapter or voltage converter as needed for your electric brush if you’re visiting another country
  • Quart size, resealable plastic bag to hold your carry-on supplies. Toothpaste and mouthwash are included in the list of items which need to fit carry-on guidelines.
  • Travel-size toothpaste—3.4 oz (100 ml) or smaller tube size. (And an almost-empty regular size tube doesn’t count!)
  • Travel-size mouthwash—also in a 3.4 oz (100 ml) or smaller container
  • Our Ashland office’s phone number. In case of emergency, Dr. John Zarrella and Dr. Peter C. Rider can give you advice on how to handle any problem which might arise when you’re far from home.

Looking for Adventure?

If you’re camping in the forest, leaving for the lake, going for a road trip, or heading out on any travel adventure, you’ll be bringing the dental care basics, of course. We’d also like to recommend some items to take along in the event of a dental emergency while you’re away from home:

  • Dental mirror
  • Cotton rolls
  • Over-the-counter pain relief—including a tube of oral pain relief gel
  • Ice pack
  • Dental wax—to cover the sharp edges of a broken tooth
  • Temporary fillings—to protect your sensitive tooth if a filling or crown is lost
  • Tooth preservation kit—to protect a dislodged tooth in case it can be reimplanted. (This means seeing a dentist very quickly, usually within 30 minutes of the accident.)

And, if you’ll be mountain biking, water skiing, or enjoying any activity where there’s potential for impact, don’t forget to pack your mouthguard!

Preparation is key to eliminating a lot of stress in our daily lives, and who couldn’t use a bit of stress-relief these days? Make room in your bag, locker, desk, luggage, or backpack for some portable, lightweight dental necessities. Be prepared to share your confident, healthy smile no matter what life has in store!

Cleaning Your Teeth—Time for a Refresher Course!

July 8th, 2026

Let’s face it, by now, brushing our teeth is something we pretty much do on auto-pilot. A quick brush after breakfast, a minute or so at night, floss when we think of it. Done. But take a few minutes to review these cleaning tips, and see if a few small adjustments to your routine could make all the difference at your next checkup at our Ashland office.

  • Tools

Some of us prefer brushing with a manual brush. Some like the electric brush for ease and comfort. Whichever form of brush you choose, be sure that it fits comfortably in your mouth, reaches everywhere it needs to, and has a handle that is easy to grip. There are many bristle options available, so if you are an energetic brusher, or if you have sensitive gums, try a soft bristled brush for gentler brushing.

If you haven’t been exploring the floss aisle lately, there are now many varieties available to suit your particular needs. Besides the traditional floss, there are coated flosses for easy gliding between teeth that fit closely together, dental tape-style flosses to fit teeth with wider spacing, and even flosses designed just for braces that thread between the wires and brackets. Talk to Dr. John Zarrella and Dr. Peter C. Rider at your next cleaning for product suggestions if you think there’s an easier, more comfortable option out there for you.

  • Technique

With proper technique, any toothbrush and floss you choose will do a fine job of removing plaque.

Brushing? There’s a tried and true method for success. Place the toothbrush at a 45° angle at the gum line. Be sure to brush the outside, inside, and chewing surface of each tooth thoroughly. Remember the expression, “Massage, don’t scrub.” Over-vigorous brushing can actually irritate gum tissue and damage enamel. An electric toothbrush should provide a continuous brushing motion without needing any pressure from the brusher. This might be the model for you if you have a too-vigorous approach to brushing, or sensitive teeth and gums. If you like your manual brush, again, give a soft-bristled brush a try!

As for flossing? That harmless-looking little string can cause gum damage if used too forcefully. You can accomplish the placement and cleaning power you need by easing the floss down to the gumline and flossing with gentle pressure against the tooth surface. If you have any questions about technique, remember—we are always happy to let you know the best cleaning methods for your specific needs.

  • Timing

Of course, the best tools and the best technique in the world won’t be effective unless you put the right amount of time into brushing and flossing.

The standard rule is two minutes of brushing in the morning and two minutes at night. If you wear braces or have other special circumstances, we might recommend brushing after every meal. And if you brush after breakfast, give your teeth half an hour or so to remineralize. This natural process uses the calcium and phosphate ions in your saliva to strengthen tooth enamel after it’s been exposed to any acidic foods in your breakfast.

Thorough flossing can be accomplished in a few minutes, and might be needed only once a day. But again, depending on your individual needs, we might have other recommendations. Let’s review what works for you at your next visit—we can tailor suggestions for a brushing routine to your unique needs.

It’s a great idea to review your brushing habits periodically to make sure you are getting the most out of those minutes you spend cleaning your teeth. There won’t be a test at the end of this review, and you won’t get a gratifying grade or a gold star. What you will get is much more important—better checkups, fewer cavities, and healthy teeth and gums. Happy cleaning!

Celebrate the Fourth with a Smile!

July 1st, 2026

As our nation prepares to observe its birthday, we’d like to share some timely dental tips to help make celebrating the Fourth of July more enjoyable for you and healthier for your teeth and gums.

Hydrate

It might be hot and humid where you’re living, so be sure to keep hydrated in the backyard or along the parade route. Proper hydration is essential for both your overall health and your oral health. Drinking water helps prevent cavities by washing away food particles and bacteria and reducing acidic conditions in the mouth. 

Use Ice for Cooling, not Chewing

If you’re enjoying an icy cold beverage to beat the heat, don’t crunch down on that ice! Chewing on ice can lead to immediate disaster in the form of a chipped or cracked tooth or a broken filling or crown. And, over time, munching ice will damage your enamel, making your teeth more sensitive to heat and cold and more vulnerable to cavities. 

Enjoy All Your Cookout Favorites

If you celebrate the Fourth with family and friends, there’s a good chance you’re celebrating outdoors. According to surveys, Independence Day is the most popular grilling day in the country. Are you sitting on the picnic table sidelines because of loose teeth, tooth pain, or missing teeth? Don’t miss out on any of the fun in Ashland! 

  • Tooth pain can be caused by cavities. It can also be a sign of a damaged tooth or an infection. If you suffer persistent tooth pain lasting several days or more, it’s time for a dental appointment.
  • Gum disease can cause bone loss, loose teeth, and lost teeth, making sharing a meal with friends something you avoid instead of something you look forward to. Regular flossing, cleanings, and checkups will help keep your gums in the pink. If you have advanced gum disease, we can discuss treatment options.
  • If you or a loved one wear braces, be sure your BBQ choices are not only delicious, but safe for wires and brackets. Offer menu options which are braces-friendly—that is, which are soft and easy to eat rather than hard, crunchy, or sticky. Remove kernels from corn on the cob and have utensils available to cut finger foods like burgers and hot dogs into fork-friendly bits. 
  • Missing teeth not only make dining difficult, but can also lead to gum disease, decay, and misalignment in adjacent teeth. To enable you to enjoy your meals and to protect your dental health, talk to Dr. John Zarrella and Dr. Peter C. Rider about implants, bridges, or dentures to make your smile complete again.

Whether you’re marching in the parade, enjoying a meal with family and friends, oohing and aahing at the fireworks, or all of the above, we wish you a healthy and happy Fourth of July! If you have any dental concerns, we’re here at Zarrella Dentistry to help you achieve your best smile every day of the year.
