Here is some surprising yet worthwhile advice you might be hearing for the first time: Brushing after a meal can be incredibly bad for your teeth if you do it after eating certain foods.

Enamel is an extremely hard mineral on the exterior of each of your teeth. It’s actually the hardest substance in the human body: It’s even stronger than your bones! Its only weakness is that acids in the food we eat can easily destroy enamel.

Healthy teeth thrive in an environment that has the proper pH balance. That ensures your mouth doesn’t start the process of demineralization. That’s what happens when alkaline turns into acid, which attacks and softens the enamel on the surface of your teeth. Pores and fissures form, and that’s when the harmful bacteria go to work.

Our mouth’s pH level fluctuates depending on what we eat throughout the day. Examples of the most common highly acidic foods include citrus fruits, soda, and sugary foods. Highly acidic foods tip the balance of pH in your mouth from a healthy alkaline to a dangerous acid.

Can brushing your teeth immediately after a meal lead to even more damage? The answer is yes!

Eating highly acidic foods causes your teeth to be more susceptible. If you brush your teeth when they have been weakened by acids, even more destruction can happen to your enamel. Your toothbrush’s bristles will actually wear away some of your enamel. So it’s healthier to wait at least an hour after eating or snacking to brush.

Good preventive measures to take instead of brushing after you eat include:

• Rinsing or drinking water
• Chewing sugarless gum
• Consuming dairy or non-acidic foods to conclude your meal

These practices help produce saliva, which in turn restores a healthy pH level in your mouth and coats the teeth with minerals they need.

Once you’ve allowed time for your mouth to be restored to a healthy pH level, you may brush your teeth as you normally would. Keep in mind that acidic foods can weaken the enamel on your teeth and take the right measures to prevent spiking pH levels.

Most important, don’t forget to wait to brush at least one hour after you eat!

It’s great that you’re enthusiastic about your dental health! Here are some tips from Dr. John Zarrella and Dr. Peter C. Rider and our team to make sure you are getting the most out of your brushing by avoiding common mistakes.

Choose the right brush

In almost every case, a soft brush provides the right amount of bristle-strength to clean your teeth and gums effectively. Hard bristles can damage sensitive enamel and gum tissue, so treat yourself kindly. Also, choose a brush head that’s the right size for your mouth, since a toothbrush that’s too large can be uncomfortable and unable to reach all the areas you need to brush.

Don’t keep your brush too long

Three months is about the average life of a toothbrush. Over time, bristles become frayed or worn and lose their effectiveness. It’s also a good idea to replace your brush after an illness.

Be gentle

Even with a soft brush, it’s possible to brush so hard that your enamel and gums are affected. Think of yourself as massaging your teeth and gums rather than scrubbing them.

Use proper technique

Using a “sawing” back-and-forth motion is hard on your enamel and misses plaque and debris between the teeth. Hold your toothbrush at a 45-degree angle, especially at the gumline, to gently remove plaque. Use short strokes or a circular motion to clean as much of the surface and between the teeth as possible. Make sure you cover all the surfaces of your teeth: outside, inside, and chewing. And don’t forget your tongue!

Take your time

Brushing twice a day for two minutes each time is the standard. Most people brush much less; try using the stopwatch on your phone or a two-minute timer to make sure you are spending enough time brushing. On the other hand, if you brush too hard or too often, remember that over-brushing can lead to problems for your gums and enamel.

Your daily routine might be fast and furious, but your dental routine requires a gentle, methodical approach. Ask at your next visit to our Ashland office, and we will be happy to help you design the perfect brushing practices for your busy life.

Should a quick bite between meals make us feel guilty? Or worse, make our teeth suffer a greater risk of cavities? Let’s avoid both those possibilities! We have several tooth-healthy snacking strategies designed to help you keep your enamel cavity-free while preventing snacker’s remorse.

But first, a word or two about why we may find snacking unappetizing.

• Please, Don’t Feed the Bacteria!

The bacteria in plaque feed on sugars and leave acidic waste products behind. These acids attack enamel, dissolving the calcium and phosphorus minerals that keep it strong. Weakened enamel leaves teeth vulnerable to decay. That’s why Dr. John Zarrella and Dr. Peter C. Rider and our Ashland team recommend avoiding a steady diet of sugary treats.

Even if you’re not reaching for a soda, or grabbing a candy bar, many snack foods are filled with added sugars. Check the nutritional labels before you indulge to avoid sugar surprises.

• Off Balance?

Bacteria plus sugar equals more acidic conditions in the mouth. This change in the oral pH balance also reduces our natural defenses against cavity-causing acids.

A well-balanced oral environment depends on saliva to keep acids in check. Saliva washes away lingering food particles after meals, and it neutralizes acidic conditions in the mouth over the course of the day.

How does snacking interfere? Immediately after eating or drinking, acids in saliva increase. It takes about 20 minutes for saliva’s neutralizing process to begin. When we snack throughout the day, saliva doesn’t have a chance to reduce acids as long or as effectively.

• Staying Power

Sticky and chewy snacks tend to stick to the tops of molars and between the teeth. This gives bacteria more fuel and more time to attack tooth enamel. It’s not just candies that are the culprits here. Chips, bread, pizza crusts, pastries—these simple carbs stick to teeth and break down easily into sugars.

But we promised some *positive* strategic snacking ideas. Here are some ways to make sure that snacking doesn’t put you at a much greater risk for cavities.

• Be Choosy

Avoid processed treats that are high in added sugars. If you’re craving something sweet, fresh fruits provide sweetness with vitamins included.

Crispy fruits such as apples and Bosc pears, as well as vegetables like celery and carrots, provide gentle scrubbing action to help clean teeth between brushings.

Snacking on cheese helps neutralize acids, and other dairy products are high in calcium and phosphorus, helping rebuild the minerals that acids leach out of enamel.

Eat whole grain breads, pastas, and pastries. They offer more nutrients, and don’t break down into sugars as easily.

Finally, when it’s time to indulge in a sugar-rich treat, save it for a meal. There’s a better chance that other foods will balance the acids created by sugar, and you’ll be getting the most out of saliva’s neutralizing abilities. Speaking of which,

• Stay Neutral

When you’re craving something flavorful without giving bacteria more fuel for acid production, consider sugar-free gum. Sugar-free gum saves you from adding sugar to your diet, and it increases saliva production as you chew. If we give you the all-clear, chewing a piece or two of gum during the day can help curb your sugar cravings and protect your enamel.

Thirsty? Drink water instead of sodas or energy drinks with your snacks. Water washes away food particles, cuts down on acidity, and provides fluoride to strengthen and protect teeth.

• To Brush or Not to Brush?

It’s always a good idea to brush after eating. But since eating sugary or acidic foods can leave enamel vulnerable to toothbrush abrasion, many dentists recommend waiting 30 minutes after you snack before brushing. Ask Dr. John Zarrella and Dr. Peter C. Rider what’s best for your teeth.

If you can’t brush, rinse with water after eating or drinking.

If you wear braces or aligners, be sure to check with Dr. John Zarrella and Dr. Peter C. Rider about snacking, gum, best times to brush, and any other diet questions.

Talk to Dr. John Zarrella and Dr. Peter C. Rider about your snacking habits. Learning when and how to snack is as important as deciding what to snack on. Finding the perfect balance means you can enjoy a mid-day energy boost without guilt—and without risking tooth decay!

Whether you’re using the latest note-taking app or old-school pen and paper, it’s a good time to start jotting down your resolutions for a healthier, happier New Year. To help the process along, we have some suggestions for traditional tooth-friendly resolutions—and also some ideas which might surprise you!

The Classics

• Brush and Floss Regularly

If you’re sticking to the “two minutes twice a day” brushing schedule as well as flossing once a day, great work! Often, though, that two-minute window starts to shrink as our brushing routine becomes *too* routine. Try timing yourself while you brush normally. If you’re falling quite a bit short of two minutes, taking just a bit more time will be lots more effective in removing plaque from your teeth.

And since gum disease is a leading cause of tooth loss in adults, commit to flossing once a day to remove irritating plaque and bacteria from between teeth and around the gumline.

• Use Fluoride Toothpaste

Fluoride toothpaste doesn’t just help prevent cavities by cleaning away plaque and food particles. It also helps make our enamel stronger. 

Acids created by plaque bacteria and acids in our diet dissolve minerals from tooth enamel, making it softer and more vulnerable to cavities. Fluoride bonds with the minerals in enamel to create an even stronger protective enamel coating. Check with Dr. John Zarrella and Dr. Peter C. Rider or the American Dental Association’s website for the best toothpaste choices for healthy, strong enamel.

• See Your Dentist Regularly

Dentists typically recommend a full dental exam and cleaning twice each year. Your dental team at Zarrella Dentistry will take X-rays as needed, examine your teeth, gums, and general oral health, and screen for oral cancer. A professional cleaning will remove any built-up plaque and tartar, which is especially important for gum health.

Being proactive with your dental care means you’ll be sharing your healthy smile all year long—as well as discovering any potential problems before they can develop into major problems!

The Surprises

• Chew (Sugarless) Gum

When you’re not producing enough saliva, you feel the effects of dry mouth, including sore throat, difficulty swallowing, and bad breath. Another side effect? Poorer dental health. 

Saliva helps neutralize the acidic foods we eat, washes away bacteria and food particles, and contains minerals like calcium and phosphorus which remineralize tooth enamel. Chewing sugarless gum encourages saliva production. If you suffer from dry mouth, check with your dentist to see if chewing sugar-free gum can help.

• Don’t Brush Right After Eating

Brushing after a meal is great to remove food particles like sugars and carbs which stick to our teeth—and which the bacteria in plaque thrive on. But if you’ve been eating or drinking acidic foods, it’s best to wait about an hour before brushing. 

Acids in foods, like acids created by bacteria, weaken tooth enamel. Brushing right away can be abrasive and damage enamel, but if you wait for an hour, the minerals in saliva have a chance to remineralize and restore your enamel strength.

• Toss Your Toothbrush

Not that we mean give up brushing altogether! But your toothbrush bristles start to fray and fan out after several months, meaning that you won’t be getting the full cleaning effects of your great brushing technique. Put a note on your calendar to replace your brush every three to four months for the best in plaque removal.

If you’re already following all these suggestions for protecting your dental health, resolve to keep up the good work! If not, give these easy-to-follow recommendations a try. Protecting your dental health is essential to gift yourself a new year filled with happy, healthy smiles in Ashland.
