Is this a trick question? After all, you probably already know quite a lot about cavities:

• It all begins when bacteria-filled plaque sticks to teeth and starts to attack enamel. How?
• Because the bacteria in plaque use the sugars and other foods we eat to produce acids.
• These acids gradually weaken teeth by dissolving minerals which help make up our enamel (a process called demineralization).
• Over time, a hole, or cavity, develops in the tooth surface.
• Left untreated, bacterial decay can spread to the inside of the tooth, creating a more serious cavity.

Some cavities aren’t discovered until you visit our East Lyme, CT office, but sometimes there are clear signs that there’s a problem.

• You have tooth pain or sensitivity.
• Your tooth changes color in spots where the enamel has decayed.
• You might even notice enamel loss when a cavity is large enough.

So, if you have any of these symptoms, it’s a cavity, right? It might be—but it might not. Sometimes, because the symptoms are similar, what we suspect is a cavity is really enamel erosion.

The bacteria-created acids weaken enamel. But it’s not just bacteria that subject our teeth to acids—we do it ourselves with our choice of food and drink. Acidic foods are one of the leading causes of tooth erosion.

Our normal saliva pH level is around a 7, which is neutral. Any number lower is acidic; any number higher is alkaline. Acidic foods have a low pH (the pH of lemon juice, for example, measures between 2 and 3), and can reduce our normal, neutral pH level. When saliva pH levels drop to 5.5 or lower, tooth enamel starts to demineralize, just as it does when exposed to the acids from oral bacteria.

Regularly snacking on citrus and other acidic fruits, wine, fruit juices, flavored teas, sour candies, and other acidic foods can cause enamel erosion. Especially erosive are sports drinks, energy drinks, and colas, because they contain some combination of citric acid, phosphoric acid and/or carbonation.

The symptoms of tooth erosion and damaged enamel can be very similar to those caused by cavities:

• You suffer tooth pain or sensitivity
• Your teeth appear discolored, as the enamel thins to reveal the yellowish dentin underneath
• You notice missing enamel—your teeth become rounded or have little pits known as cupping

You call Dr. James Robson right away if you suspect a cavity. Be just as proactive if you suspect erosion. Even though your symptoms may not have been caused by plaque and bacteria, acidic erosion from your diet leaves weakened enamel just as vulnerable to cavities and decay.

How to avoid erosion?

• Enjoy acidic foods sparingly, or as part of a meal. This helps your saliva pH stay in the neutral zone.
• Balance acidic foods with low-acid choices to help neutralize acids and restore a normal pH balance. (A good reason to pair wine or fruits with cheese.)
• Use a straw! This simple solution keeps erosive drinks from bathing your teeth in acids.
• Drink water instead of an acidic beverage, or drink it afterward to rinse your mouth. The pH of pure water? A perfect, neutral 7.
• And what about brushing right after eating or drinking something acidic? Ask Dr. James Robson if you should rush for your brush. We may recommend waiting 30 minutes or so after an acidic treat to give teeth time to remineralize after acids weaken them. Otherwise, brushing might cause more wear and tear on your enamel.
• Finally, while foods are often the source of acid erosion, medical conditions can cause erosion as well. Talk to us about ways to minimize erosion while addressing your medical needs.

There’s no trick to it—watching your diet, brushing and flossing as recommended, using a fluoride toothpaste, and visiting Robson Dentistry for regular checkups will help prevent tooth erosion. We can restore eroded enamel with bonding, veneers, or crowns if the erosion is serious. Better still is to catch erosion before symptoms appear to keep your teeth their strongest for a lifetime of healthy, beautiful smiles.

Molars are difficult to reach when brushing your teeth because they’re full of crevices, caves, and pits that can provide the perfect environment for decay. Sealants are the perfect fix for this.

Sealants are a plastic-like protective solution that bond to the edge of the tooth. The treatment protects you against cavities and could save you from complicated dental issues in the future.

The process for placing sealants is painless and quick. First, Dr. James Robson will clean the tooth with a baking soda spray. An acid etch is applied in order to “roughen up” the surface of the tooth and re-mineralize the area. The area is dried with an alcohol-based liquid and the sealant is placed on the grooves of the tooth. A special light then hardens the liquid into a plastic-like material.

Although sealants can last several years, they need to be examined semi-annually to check for breakage. Any cracks or breaks in your sealant can put your tooth at high risk for decay, and repair of sealants is a quick and painless task.

Children often receive sealants, but people of all ages can benefit from them. Adults who have especially deep canyons on their teeth are good candidates for sealants.

An investment in dental sealants can prevent tooth decay and complicated dental problems later on. It’s a no brainer! Call our East Lyme, CT office today to speak with us about getting sealants on your teeth.

Hiking is a great way to appreciate the beauty of nature, to get away from the stresses of daily life, and, of course, to challenge yourself physically. While you’re packing away your sunscreen and your first aid kit, do your body another favor—take a minute to include some lightweight, dental-friendly items.

• Snacks

When you’re exerting yourself, snacks that provide quick energy on the go are a must. Granola, trail mix, energy bars, candy, dried fruit—these are the foods we think of as trail food, and we generally get that quick energy boost from the sugars and starches they contain. As it happens, Dr. James Robson and our team strongly recommend you pick snack options other than sugary and starchy foods. Why? Because many sugars and starches provide oral bacteria the food they need to produce acids. These acids weaken enamel and damage our teeth. And these common trail foods often have the added “bonus” of sticking to the teeth, leaving acids even more opportunity to attack. Don’t give up the energy boost you need for a safe hike, but do yourself and your teeth a favor and look for the healthiest granola, energy bars, and gorp out there.

Other suggestions for trail treats that are also a treat for teeth? If you need a chocolate pick-me-up, try dark chocolate. Dark chocolate has more caffeine that milk chocolate and less sugar. (It has other health benefits as well that you might want to look up after your hike.) If you like nuts and seeds, take softer nuts, or sliced nuts—a good source of energy and not likely to provide as much stress on your teeth when you’re in the field. (Shell them beforehand—don’t ever use your teeth as a nutcracker!) Similarly, if you take seeds, leave the shells at home. If you like crackers, try whole grains. Looking for protein? How about a tuna pouch instead of chewy beef jerky?

• Hydrate

Water is always the go-to beverage. Pre-hydrate even before setting out, and have plenty on hand for your trek. Many hiking sources suggest two cups of fluids per hour of activity. (And in hot or humid weather or at high altitudes, you could need even more.) There are actually hiking water calculators online, which can give you a good estimate on how much you’ll need for your trip, taking into account your age, weight, level of activity, and other factors. Because water can get heavy, plan a lengthy hike around the availability of fountains or other clean water sources if necessary.

What if you feel the need for more than water? If you are getting a good workout, you’re probably losing electrolytes. Generally, sports drinks aren’t on the dental menu. They tend to be loaded with sugar and carbs—good for energy, bad for teeth. Sports drinks can be as acidic and hard on your enamel as sodas. But if you need those electrolytes on a long hike, don’t feel guilty. There are many options—choose the healthiest one for you and your workout level.

• Be prepared!

While you are probably already packing a mini-first aid kit for long hikes, think about a lightweight dental emergency kit as well. These are readily available online and in outdoors stores, and usually contain supplies like cotton balls, dental floss, oral pain relievers, even temporary fillings, in a lightweight bag.

And once your hike is done? Rehydrate, and don’t forget to treat your teeth to a good brushing and flossing when you get home.

Got all that? Great! Now, go take a hike!

What is the strongest part of our bodies? Do you think it might be our bones, which help us move and protect our brains, hearts and other organs? Or could it be those tough fingernails and toenails that guard our fingertips and toes? Nope! You might be surprised to learn that the hardest thing in our bodies is the enamel which covers our teeth!

Our bones grow with us and can even knit back together in case we have a broken arm or leg. Our toenails grow more slowly, and our fingernails grow more quickly, so regularly trimming is required for both. But our enamel doesn’t grow or repair itself when it is damaged, so it needs to last us a lifetime. How can such a strong part of our bodies be damaged? And can we do anything to protect our teeth? Luckily, we can!

Prevent Chips and Cracks

You might be the fastest on your bike, or the highest scorer on your basketball team, or able to do the most amazing tricks on your skateboard. But even the strongest teeth can’t win against a paved road, or an elbow under the basket, or a cement skate park. If you’re physically active, talk to us about a mouthguard. This removable appliance fits closely around the teeth and can protect your teeth and jaw in case of accident. And protect your enamel even when you’re not being adventurous! Don’t bite down on ice cubes or hard candy, and save your pens and pencils for writing, not chewing.

Guard Your Teeth from Tooth Grinding

If you grind your teeth, you’re not alone! Many other young people do, too—mostly in their sleep. In fact, it might be a parent or sibling who lets you know you are grinding at night. But constant pressure on your enamel can lead to cracked enamel, sensitivity, and even worn down teeth. How can you protect them? Once again, a mouth guard can be a great solution. We can custom fit one to allow you to sleep comfortably while protecting your teeth.

Eat Healthy Foods & Brush Regularly

We all have bacteria in our mouths. Some are helpful, and some are not. The bacteria in plaque can change food products like sugar and starches into acids. These acids actually break down our enamel, which can lead to tooth sensitivity and decay. Making sugars and carbs a small part of your regular diet, and eating meals rich in proteins, vitamins, and minerals, will help stop acids from attacking your enamel. And careful brushing and flossing twice a day with a fluoride toothpaste can help keep those minerals in enamel from breaking down and even help restore them.

Your enamel is the strongest part of your body, and you can help it stay that way. Protect your teeth from accidents, let our East Lyme, CT team know if you or a parent suspect you are grinding your teeth, eat healthy foods, and keep up your regular brushing. And remember, we are here to help keep your family’s teeth and mouth their healthiest for your strongest, most beautiful smile.
