This may come as a surprise, but brushing your teeth right after a meal can be one of the worst things you can do for your healthy teeth. A toothbrush can be considered an assault weapon against your smile if used immediately after eating certain foods.

Enamel is like the tooth’s shield. It is a hard mineral exterior on each of your teeth. In reality, enamel is the hardest part of the human body—even stronger than bone! I like to regard it as a “super-structure.” But every superhero has a weakness, and enamel’s kryptonite is acid.

A healthy tooth lives in a mouth that has a proper pH balance. When that balance tips from alkaline to acidic, a harmful process called demineralization begins. Demineralization occurs when acids attack and soften the tooth surface. Pores and fissures form and harmful bacteria move in.

With each bite of food or drink, our mouth pH fluctuates. Highly acidic foods tip the balance of your mouth from a healthy alkaline to a dangerous acid. Here are some examples of those sources of acid: citrus fruits, soda, and sugary foods. There are certainly many others, but these are the most common.

So how does brushing your teeth immediately after a meal make this process even worse?

After eating highly acidic foods, your teeth are susceptible to damage. When you brush your teeth in this weakened state you are actually damaging your enamel. The abrasive bristles of the brush wear away the protective surface of the teeth. You should avoid brushing for at least an hour, or take other, simple preventive measures immediately following a meal.

First, rinse with or drink clear water. Then chew some sugarless gum. Both of these practices will produce saliva, restore a healthy pH level in your mouth, and coat your teeth with nourishing minerals. Out of all the sugarless gums available, the best of the best are those that list xylitol as the first ingredient. Another option is to consume cheese, milk, or another non-acidic food or drink to conclude your meal.

After you have given your mouth time to return to a healthy pH, feel free to brush your teeth. Just keep in mind that any time you eat acidic foods, you weaken your teeth. Make sure not to worsen the problem by brushing immediately after dining and damaging your teeth even more. Questions? Call us at Erich M. Werner, D.D.S..

Rumor has it that the Queen of England doesn’t allow garlic in the palace. And, even if you have no royal duties in the near future, it might be a good idea to avoid foods like garlic and onion before a big presentation or a first date. But if your diet is filled with mint, fresh apples, and parsley and you still worry about your breath, here are some common causes for bad breath that you might not have considered.

• A Slip of the Tongue

We brush and floss to remove food particles and bacteria. After all, bacteria that linger in the mouth produce acids that damage tooth enamel and cause bad breath. But there is one important brushing target you might be overlooking—your tongue.

Remove food particles and bacteria on the surface of the tongue with a gentle brushing after you have finished cleaning your teeth. With a dab of toothpaste, brush the top of your tongue gently from back to front. There are also tools called tongue scrapers available that are specifically designed to remove food particles and bacteria from the tongue’s surface. However you choose to clean your tongue, remember to move from the back to the front, and always clean gently.

• A Dry Spell

We spend the vast majority of our day not brushing our teeth. What helps keep breath fresh even during the hours between brushings? Saliva! As saliva bathes the teeth throughout the day, it not only washes away food particles and bacteria, but also neutralizes the enamel-damaging acids that are produced by bacteria. Yet another benefit? Saliva is not a friendly environment for the oral bacteria that produce volatile sulfur compounds (VSCs). It is these compounds that cause most of the unpleasant odors we know as bad breath.

If you are drinking the recommended amount of water each day, you are helping your body produce saliva and fight bad breath. Sometimes, a medical condition called dry mouth, or xerostomia, interferes with saliva production. Talk to Dr. Werner about ways to deal with dry mouth. Solutions as simple as drinking more fluids or chewing sugarless gum can help, or we can suggest over-the-counter products or prescription medications if needed.

• A Bad Night’s Sleep

We’re all familiar with the concept of morning breath. As we sleep, our saliva production naturally decreases. It’s like a nightly version of dry mouth. Without normal levels of saliva, bacterial growth takes off, VSC’s are produced in greater quantities, and we wake up wondering what on earth happened to that fresh feeling we had after brushing the night before.

Unfortunately for snorers, nighttime brings more problems. Snoring leads to mouth breathing, and mouth breathing creates an even drier environment where oral bacteria increase more quickly. If you find you are consistently waking up with an especially unpleasant case of morning breath, you could be a chronic snorer without even realizing it. If you discover or suspect you have a snoring problem, talk to Dr. Werner or your GP. Snoring can have serious health consequences, so let’s discuss possible solutions.

One important note to end on: if you have eliminated all the obvious causes of halitosis but still have persistent bad breath, give our Los Gatos, CA office a call. Chronic bad breath can be a symptom of serious gum disease, oral infections, illnesses such as diabetes or kidney disease, and other medical conditions that should be treated as soon as possible. If the topic is bad breath, let’s make sure garlic is the only thing you have to worry about.

In a perfect world, we would all jump out of bed ready to greet the day with a big smile and a toothbrush close at hand to clean our teeth immediately. But if you can’t even find your toothbrush before you’ve had your first cup of coffee, does it really make a difference if you brush and floss after breakfast? Perhaps! Let’s talk biology.

Normal saliva production during the day benefits our teeth and mouths in surprising ways. Saliva washes away food particles to keep our teeth cleaner. It contains cells which combat bacteria and infection. It even provides proteins and minerals to help protect our teeth from decay. But saliva production slows dramatically as we sleep, and the amount of bacteria in our mouths increases. While one of the nasty—and obvious—side effects of bacterial growth is morning breath, there is an invisible effect, which is more harmful. Bacteria in plaque convert sugar and carbohydrates into acids which attack our gums and enamel and can lead to both gingivitis and cavities.

• If You Brush Before Breakfast

Brushing and flossing first thing in the morning removes the plaque that has built up during the night and takes care of many of the bacteria who are ready to enjoy the sugar and carbs in that breakfast with you. If you brush before eating breakfast, rinse your mouth with water after your meal, floss if needed, and you are good to go.

• If You Choose to Brush After Breakfast

But if you decide that doughnut simply can’t wait, you should ideally postpone brushing for 20-30 minutes after your meal. Of course, these are minutes in which bacteria can make use of those new sugars and carbohydrates. So why shouldn’t you brush immediately after eating? Many foods and beverages, especially acidic ones such as grapefruit and orange juice, can weaken the surface of your teeth. If you rinse with water after eating and wait at least 20-30 minutes before brushing, your enamel will be “remineralized” (another benefit of saliva) and ready for cleaning.

No matter if you take a “seize the day” approach and brush first thing in the morning, or a “seize the doughnut” approach and brush soon after eating, the important word here is “brushing.” Dr. Werner and our Los Gatos, CA team are happy to make suggestions as to the best morning routine for you. One thing is certain: if you give your teeth and gums two minutes of careful brushing and flossing in the morning, you can’t help but start your day off right!

We all want to live our healthiest lives. We know that part of keeping ourselves healthy is regular visits to our Los Gatos, CA office for checkups and necessary dental work. And that dental work might require an X-ray. Should the amount of radiation in an X-ray concern us?

First, it is helpful to know that the radiation you are exposed to from a dental X-ray is very small. A set of most bitewing X-rays, for example, produces an amount of exposure about equal to the amount of background radiation we get from our normal surroundings in a typical day. We also take care to minimize your exposure even further by using specially designed equipment and protective shielding, and taking only necessary X-rays. If your child is very young, if you are pregnant, or if you have other health concerns, talk to us about the advisability of X-rays and whether they are essential to treatment.

Second, much of our careful general examination will be done visually. Dr. Werner can check for cavities and other problems and assess tooth and gum health. But sometimes, there are conditions which can’t be detected without an X-ray.

• Decay that isn’t visible in an oral exam—if a small cavity develops between teeth, or is hidden underneath a filling, an X-ray will catch it before more damage can take place.
• Infection—An X-ray will reveal infections such as abscesses that can damage both bone and tooth, and gum disease that has harmed bone and connective tissue.
• Orthodontic and periodontal issues—We might need an X-ray to determine the spacing and development of your child’s incoming teeth and maturing jaw structure, to properly create braces for adults or children, or to place an implant within the jawbone.
• If you are a new patient, it is helpful to have complete X-rays taken as a baseline of your current dental health and previous dental work. This baseline allows us to track tooth and jaw development, if necessary, and to evaluate any future changes that might be a concern. (If you have had X-rays taken in another office, we can help you have them transferred so we have a background of your dental history.)

Even though the radiation from a dental X-ray is minimal, be assured that we will never request any unnecessary procedure. When we recommend an X-ray, we do so to make sure there is no decay or infection threatening the health of your gums and teeth, and that we have the essential knowledge we need to treat any dental, periodontal, or orthodontic condition. Because we all want to live our healthiest lives—and part of that healthy life is both active and proactive dental care.
