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.

The Secret to Keeping Your Teeth for Life

June 24th, 2026

The secret to keeping your teeth for life involves more than one secret. The first is that there is no secret; and in fact, there really is no difficulty involved. Follow this simple four-step process – brush, floss, rinse, and visit our Ashland office regularly – and you will have healthy teeth for life!

Brush

You should brush your teeth twice a day, preferably once in the morning and once at night. Three times a day will not hurt. Use a soft-bristled toothbrush and light pressure; you do not want to scrub away your gums or tooth enamel.

Brush for a minimum of two minutes, and carefully clean all tooth surfaces. Three minutes is better. Use quality toothpaste; Dr. John Zarrella and Dr. Peter C. Rider and our staff can recommend the best type for your needs. Keep your toothbrush clean and replace it about every three months.

Floss

Make flossing part of your daily routine, at least once a day. Flossing is important for more than just removing food particles between your teeth. The process also helps to remove bacteria that you cannot see. Bacterial build-up turns into plaque, or calculus: a cement-like substance that cannot be removed by brushing alone.

Use floss gently; you do not want to cut your gums. There are many different types of flosses and flossing tools. Dr. John Zarrella and Dr. Peter C. Rider and our staff will be happy to help you find the style that works best for you.

Rinse

Mouthwash does more than freshen your breath. Rinses help kill the bacteria that lead to plaque formation and gum disease. This extra step can go a long way toward having healthy teeth for life.

Keep your appointments

You should have a professional cleaning at Zarrella Dentistry twice a year. Some patients benefit from more frequent cleanings. Your hygienist will remove any plaque build-up to prevent gingivitis, which left untreated becomes full-blown gum disease. Periodontitis leads to tooth loss.

You also need to see Dr. John Zarrella and Dr. Peter C. Rider twice a year for a teeth and mouth exam. We can find problems such as cavities, and treat them before the situation becomes critical. Ask our Ashland team any questions you have; together we can make your teeth last for life.

Protect Your Enamel from Dental Erosion

June 17th, 2026

We know that the foods we eat and drink can have a definite impact on our smiles. Staining is an unhappy side effect of many of our menu favorites. That’s why we sip red wine through a straw, rinse with water after a slice of blueberry pie, and cut back on the coffee and tea after a single cup (or two—we’re not perfect!). And sugar is the fuel for cavity-causing bacteria, so we try to substitute water for soda, or replace the hot fudge sundae with grilled fruit. And we always brush carefully after indulging.

So far, so good. But while we’re saving our brilliant smiles from stains and decay, let’s not forget one other source of diet-related damage—acids. Acidic foods and beverages can actually erode the surface of our enamel, leaving our teeth more vulnerable to sensitivity and discoloration.

What Is Dental Erosion?

Enamel is the strongest substance in our bodies—stronger than bone—but it is not indestructible. And acids are one of the major causes of enamel damage. (In fact, it’s the acids produced by bacteria that lead to cavities.) Luckily, our bodies are designed to protect our enamel. Saliva helps clean the teeth by washing away food particles and it neutralizes acidity as well. But a diet that’s too heavy in acidic foods can undo all this good work and upset the healthy pH balance in our mouths.

Why is this a problem? Because acidic environments actually cause the minerals in our enamel to break down, a process known as “demineralization.” This weakening of the enamel leaves teeth more sensitive to heat and cold. It can even lead to discolored teeth, as thinner enamel allows the brownish-yellow dentin underneath the enamel surface to become visible.

Are You Aware of Acids?

We can immediately guess at some of the most acidic foods. Citrus fruits and juices, tomatoes in their many culinary forms, anything pickled in vinegar, coffee, tea, wine—these foods are certainly acidic, but also a regular part of many a healthy diet. You don’t need to avoid these foods altogether, but it’s best to enjoy them as part of a meal or enjoy them sparingly. And balance out some of these high-acidity foods at mealtime with low-acidity choices like bananas, bread, and dairy products.

Other sources of damaging acids might surprise you. Studies have linked sodas, energy drinks, and sports drinks to higher levels of tooth erosion. The combination of citric acid, phosphoric acid and/or carbonation raises acidity levels in the mouth. And because we tend to sip them all day long, it’s like a continuing acid bath for our enamel. Water is always a healthy alternative for hydration, but if you do indulge in a soda or sports drink, rinse with water after drinking. And don’t swish—just swallow.

Won’t Brushing Help?

Yes, but watch your timing. Because the acids in foods weaken enamel, brushing right after a big glass of orange juice or a soda can actually be even more abrasive for tooth surfaces. We recommend waiting anywhere from 20-60 minutes to brush. This gives your saliva the chance to not only wash away acids, but to “remineralize” your teeth, bathing them in the phosphate and calcium ions that strengthen enamel.

If you notice any of the symptoms of dental erosion, including pain, sensitivity when you eat or drink something hot, cold or sweet, or yellow discoloration, talk to Dr. John Zarrella and Dr. Peter C. Rider during your visit to our Ashland office about what you can do to help protect and strengthen your teeth. Unfortunately, our bodies can’t produce new enamel. By avoiding foods that stain, by reducing sugars that lead to decay, and by limiting the acidic foods that erode our enamel, we give ourselves the best opportunity for a lifetime of beautiful, healthy smiles.
