Many people who are careful about brushing and flossing their teeth wonder how they still end up with cavities or tooth decay. Several factors affect wear and tear on tooth enamel. Diet is a major factor, with certain foods increasing the likelihood that your enamel will become discolored or decayed. Pay close attention to the foods you eat to keep your pearly whites looking healthy and clean.

What causes enamel damage?

Tooth enamel refers to the hard, semi-translucent, whitish part of the tooth that shows above your gums. The enamel is primarily composed of minerals that are strong but susceptible to highly acidic foods. When acid reacts with the minerals in enamel, it results in tooth decay. Strongly pigmented foods can also damage enamel by discoloring the surface of the tooth.

Foods that harm enamel

Acidic foods are the greatest source of enamel damage. To determine whether a food is acidic, look up its pH. Scientists use pH, on a one-to-seven scale, to define the relative acidity or alkalinity of a substance. Foods with low pH levels, between a one and three, are high in acidity and may damage your enamel. Foods with high pH levels, such as a six or seven, are far less likely to cause enamel harm.

So which foods should you avoid? Many fruits are high in acidity, including lemons, grapefruit, strawberries, grapes, and apples. The high sugar and acid content in soda makes it another huge contributor to enamel decay. Moderately acidic foods include pineapple, oranges, tomatoes, cottage cheese, maple syrup, yogurt, raisins, pickles, and honey. The foods that are least likely to cause enamel damage include milk, most cheeses, eggs, and water.

Beverages such as red wine and coffee also damage the enamel by discoloring it. Although stains do not necessarily undermine the integrity of your teeth, they can be unsightly.

What can I do to prevent enamel damage?

Fortunately, there are several measures you can take to prevent your enamel from discoloring or decaying. The easiest way to avoid decay is to steer clear of high-acidity foods. This may not always be possible, but eliminating sugary fruit juices and soda from your diet is a good start. Brushing your teeth after each meal and flossing frequently also preserves your enamel. Another good idea is to rinse your mouth with water or mouthwash after eating to wash away high-acidity particles.

Although enamel damage is common, it does not have to be an inevitable occurrence. Knowing the foods that harm your teeth gives you the tools to prevent discoloration and decay. With some easy preventive measures, your teeth will stay strong and white for years to come! Give us a call at Central Park West Dental to learn more!

October 31—Halloween. Fourth Thursday in November—Thanksgiving. And, in between these two favorite autumn holidays, we have November 1—National Brush Day!

Okay, okay. Maybe National Brush Day isn’t quite as well-known as Halloween or Thanksgiving, but we take any opportunity to celebrate your dental health. So, let’s celebrate brushing!

After all, brushing is vital for healthy teeth and gums.

• Brushing is your first line of defense against plaque. Plaque forms all day long. Plaque sticks to your teeth. Plaque is filled with bacteria which produce cavity-causing acids. Brushing regularly means plaque won’t stay on your teeth long enough to cause serious tooth decay.
• Brushing is also important for your gum health. Angling your brush to carefully clean plaque and bacteria away from your gum line helps prevent gum disease.
• Tooth decay is the most common chronic disease among children and young adults. The leading cause of tooth loss in adults is gum disease. Good brushing habits help prevent tooth decay and gum disease—a win/win when it comes to your oral health.

To make the most of the time you spend brushing, let’s take a moment to review some basics on National Brush Day.

Are You Brushing Correctly?

• Big, broad brushstrokes aren’t the answer. Instead, use small up-and-down or circular strokes over each tooth and each tooth surface—outside, inside, and on the flat surfaces of your molars.
• Because plaque forms all day, you need to keep on top of it. Brushing at least twice a day for two minutes each time is a good general rule. Dr. David Shipper and Dr. Howard Vogel will let you know the best brushing schedule for your individual needs.
• Brushes are meant to clean, not to scrub. You don’t need a heavy hand for cleaner teeth.
• Which also means, there’s almost never a good time to brush with a hard-bristled brush. Hard bristles, along with hard brushing, can actually damage your enamel and gum tissue. Stick to a soft-bristled brush for dental TLC.

Are You Taking Care of Your Brush?

• To clean away bacteria and viruses you might have picked up during the day, wash your hands before brushing and flossing.
• Shake your brush dry when you’re finished and then let it air dry upright with the handle pointing down. Only use a case for travel, and make sure it has air holes for ventilation. (Bacteria thrive in a wet environment.)
• If your toothbrush lives in the bathroom, close the toilet seat before flushing to avoid airborne particles.
• No matter how close you are to your family members or roommates, don’t share your toothbrush. Sharing doesn’t mean caring in this case—it means sharing germs. Your brush should keep a healthy distance from other brushes as well.
• And no matter how fond you are of your brush, be prepared to replace it often! Most brushes last three to four months at best, because bristles start to fray and can’t clean effectively after several months of use.

It’s no coincidence that National Brush Day comes right after Halloween, the most sugar-filled holiday of them all. So, how can we mark the occasion?

Treat yourself to a new toothbrush! Take a moment to review your brushing habits. If you have young children at home, spend two minutes brushing together to make sure they’re brushing effectively–they might even have some tips for you! Brushing your teeth properly is one of the easiest things you can do to protect your oral health. That’s something to celebrate!

Sports and energy drinks cause irreversible damage to the teeth of teens and young adults. A recent study published in General Dentistry states that energy and sports drinks contain so much acid that they begin destroying teeth after only five days of consistent use. According to the Academy of General Dentistry, an estimated 30 percent to 50 percent of U.S. teenagers consume energy drinks and as many as 62 percent consume at least one sports drink per day. The high acidity levels in the drinks erode tooth enamel and the result is irreversible damage.

Dr. David Shipper and Dr. Howard Vogel and our team at Central Park West Dental encourage our patients to limit their intake of sports drinks. The enamel erosion ultimately makes teeth more susceptible to bacteria and that can lead to hypersensitivity, staining, and tooth decay. If you do consume an energy or sports drink, make sure to wait at least 45 minutes until you brush, as consumption of acidic drinks causes tooth enamel to soften, making teeth more vulnerable to wear from the abrasives found in toothpaste.

Tooth decay is the most common chronic childhood disease, five times more common than asthma. It’s also preventable with proper care. Dr. David Shipper and Dr. Howard Vogel and our team can help identify early signs of erosion and offer solutions on how to prevent further damage and more serious problems from occurring.

Probably because, for many kids, molars do get more cavities. So let’s answer two better questions: Why do molars get more cavities? And, how can we help prevent them?

It’s the Pits. (And Fissures.)

The reason molars are so useful—and more likely to develop cavities—is because of their shape. Unlike our front teeth, which are used to bite through foods, molars are used to grind and chew. That’s why they are so much larger, with a flat surface on top. Well, not exactly flat.

When you look at a molar, you’ll notice that the top isn’t really smooth at all. It’s covered with little indentations known as pits and longer grooves called fissures. These irregular features both trap food particles and make it more difficult for bristles to clean them away. Cavities in molar surfaces are so common that they even have a specific name: “pit and fissure cavities.”

But molar biology does not mean tooth decay is inevitable! There are steps you can take to protect your children’s molars as they grow, while you’re providing them with dental strategies that will keep their adult molars healthy and cavity-free.

Preventing Pit and Fissure Cavities

• Don’t Just Brush—Brush Effectively

The first step in preventing any kind of cavity is brushing properly. Your child should be brushing at least two minutes, at least twice each day. And while the time we spend brushing is important, technique is also key.

When you’re showing your child how to brush, be sure that the tops of molars, upper and lower, get brushed thoroughly, with special emphasis on cleaning pits and fissures. Make sure the toothbrush is small enough to fit your child’s mouth comfortably and reach all the tooth surfaces. Replace worn-down brushes or electric toothbrush heads after three to four months when they no longer clean as effectively.

Your child will probably need adult supervision from toddler years through the early years of grade school to learn how to brush properly. This is time well spent, as your child learns cavity-preventing brushing techniques which will last a lifetime.

• Eat a Tooth-Healthy Diet

Plaque bacteria use the sugars in our food to make acids. These acids break down the mineral strength of tooth enamel and eventually lead to cavities. And because pits and fissures are great hiding places for bacteria and food particles (especially sticky ones), molars are even more at risk for cavities. Limiting sugary, sticky foods like sweet treats and simple carbs helps reduce that risk.

Acidic foods like flavored juices, sour candies, sodas, and power drinks also weaken enamel and can leave teeth more vulnerable to decay. Help your child avoid cavities by limiting acidic foods and drinks, making them part of a balanced meal, and/or rinsing with water after eating.

• Use Fluoride Toothpaste

Fluoride toothpaste not only reduces the risk of cavities, it also helps strengthen enamel that has been weakened by bacterial and dietary acids. Win-win!

• Ask About Sealants

Sealants are invisible, safe coatings which protect molars by preventing food and bacteria from getting trapped in their uneven surfaces. The top of the molar is first treated with an etching solution to allow the sealant to bond tightly to the tooth, a thin coat of sealant is painted on, and then it’s hardened under a curing light. That’s all there is to it.

Sealants are often recommended when children’s permanent molars first erupt, when they are especially at risk for cavities. Sealants can last from three to five years (or even longer), and studies have shown a dramatic reduction in cavities for patients who use sealants compared to patients with untreated teeth. Depending on your child’s individual needs, Dr. David Shipper and Dr. Howard Vogel might recommend a sealant for baby molars as well.

• Regular Exams and Cleanings

It might be hard for you to tell if your child’s molars have been affected by sticky plaque, or sugary foods, or acidic drinks, or inadequate brushing, or any other potential cavity-causers. It’s not a difficult job for Dr. David Shipper and Dr. Howard Vogel, though! Through regular checkups and cleanings at our New York, NY office, we will discover any conditions that might lead to cavities, and, if necessary, treat small cavities before they lead to more serious decay.

Statistically, childhood molars have a greater chance of developing cavities than incisors and canines. Help your child beat the odds by understanding why these teeth are at risk and by working with your dental team to give your child years of healthy teeth now and a future filled with beautiful smiles!
