So you might be wondering, just what are cavities? How do we get them? What do they do to our teeth? How can we prevent them? Let’s talk!

Our teeth need to be strong to bite and chew. That’s why they are protected by a coating called enamel, which is made up of very hard minerals. Enamel is the strongest part of our bodies—stronger even than our bones. But this doesn’t mean nothing can hurt it! And cavities, also called tooth decay, are one of the most common dangers facing our enamel.

So, what are cavities?

A cavity is a hole in your tooth enamel. If your tooth is not cleaned and repaired when a cavity is small, this hole can grow bigger until tooth decay reaches the inside of your tooth. Enamel doesn’t heal when it’s damaged, so you need to see a dentist to make your tooth healthy again.

How do we get cavities?

Bacteria are tiny little germs. Many kinds of bacteria live in our bodies, and some of them are quite helpful. The bacteria which cause cavities are not. These unhelpful bacteria join with our saliva and very small pieces of the food we’ve chewed to make a sticky film called plaque.

Like other living things, the bacteria in plaque need food. They get that food from the foods we eat, especially sugars and starches. As they eat, they change these sugars and starches into acids, and these acids attack the minerals which keep enamel hard and strong.

Because plaque sticks to our teeth, bacterial acids are able to make weak spots in enamel if the plaque isn’t brushed away. If you see a white spot on your tooth, that could mean that your enamel is losing minerals, and getting weaker.

What do cavities do to our teeth?

Over time, weak spots can grow bigger until there’s a hole in the enamel surface. If the cavity in your enamel is small, you might not notice it at first. But cavities can become wider and deeper, and even break through enamel to reach the inside of your tooth.

The inside of each tooth holds pulp, the part of your tooth which keeps it healthy. If tooth decay spreads to the pulp, it can cause more damage and infection, so it’s important to treat a cavity right away.

Dark spots on your enamel, a toothache, pain when you drink something hot or cold or when you bite down—these can be clues that you have a cavity, and you should visit us for an exam.

How can you prevent cavities?

Even better than treating a cavity is preventing one. Let’s make a list of some helpful do’s and don’ts for cavity prevention:

• Do: Feed yourself foods which are good for you.

Foods like milk and cheese and many dark green vegetables have lots of calcium and vitamin D to help keep your enamel strong.

• Don’t: Feed bacteria foods which are good for them.

Sugar and simple starches like potato chips are the kinds of foods bacteria like best, because they are easy to break down. This means more acids to attack your enamel.

This doesn’t mean you should never enjoy a treat! But eating lots of starchy snacks and drinking sugary sodas means more plaque, and more plaque can mean more cavities. If you’re eating something starchy or sweet, it’s a good idea to brush or rinse afterward.

• Do: Brush at least twice a day, for at least two minutes, with fluoride toothpaste.

This is the best way to get rid of plaque, which builds up every day. And fluoride toothpaste even helps make your enamel stronger.

• Don’t: Forget to floss.

Flossing takes a while to learn to do well, but it’s very important. Flossing helps prevent cavities between the teeth and near the gums.

• Do: Visit our East Lyme, CT dental office for exams and cleanings.

Not only will we look for cavities, we’ll let you know the best way to brush and floss so you can get your teeth their cleanest.

• Don’t: Feel bad if you get a cavity!

Some people are more likely to get cavities than others, even when they brush just right and eat healthy foods. If you have a cavity, we can remove decay and repair your tooth with a filling.

And one last thing to do: talk to Dr. James Robson if you have any questions about the best ways to protect your teeth from cavities. We have lots of suggestions to help you take care of your healthy, beautiful smile!

You and your dentist are essential partners in making sure you have the best dental care. You do your part by eating a tooth-healthy diet, brushing and flossing as recommended, and seeing Dr. James Robson regularly for checkups and cleanings.

And one more essential step you can take for your dental health? Let Dr. James Robson know which prescriptions and over the counter medications you’re taking.

Medications Have Oral/Dental Side Effects

We’ve all grown used to hearing “Possible side effects include . . .” at the end of every pharmaceutical commercial. That’s because those unintended side effects can affect our health in any number of unexpected ways—and this includes oral health.

For example, a common side effect of many medications is xerostomia, or “dry mouth.” Because saliva helps keep our teeth and gums healthy by washing away food particles and oral bacteria and by reducing acidity in the mouth, a reduction in saliva production means a greater risk of cavities, gum disease, oral infections, denture discomfort, and bad breath.

Knowing a patient is taking one of the hundreds of medications which cause xerostomia allows Dr. James Robson to both monitor the condition and suggest the most effective treatment options to control unpleasant symptoms.

Medications can cause not only dry mouth, but excessive gum tissue growth, oral sores, tooth discoloration, and changes in taste, among other side effects, so knowing which medications you’re taking can provide essential information for the diagnosis and treatment of these conditions.

Medications Interact

Medication might be needed for your dental treatment. Because certain drugs, supplements, and even some vitamins and foods can affect the way our bodies metabolize, absorb, and respond to other medications, we need to know which medicines you’re taking to arrive at your best treatment options.

• There are different classes of antibiotics used to treat oral infections. Knowing your medical history enables Dr. James Robson to choose an antibiotic option which won’t interact with your other medications.
• Local anesthetics such as lidocaine, which numb the area to be treated, can also interact with certain medications. Dr. James Robson can prescribe an alternative local anesthetic or adjust the dosage as needed.
• If you will be using sedation during your procedure, you have several options, including nitrous oxide gas, oral sedation, or IV sedation. Be sure we know about all of your medications beforehand because of possible interactions. Changes can be made to the type of sedation and/or the dosage as needed.

Medications Impact Treatment

It’s important for Dr. James Robson to know if any of your medications will affect standard treatments.

Anticoagulants, for example, are a necessary medication for preventing blood clots from forming, and are often prescribed for certain heart conditions, after joint replacement surgery, or for anyone at risk for developing blood clots. Because these medications prevent the blood from clotting, it’s important to let us know if you are taking such drugs before any kind of oral surgery.

If needed, Dr. James Robson can work with you and your doctor to create a treatment plan which will be safe, effective, and designed to work with any of your medications. You should never discontinue taking your prescribed medications before dental work without medical approval, as this can be dangerous.

We need the most up to date information about your health to provide you with the best care possible. Knowing which medications you take and why you take them can help us:

• Diagnose and treat any side effects from non-dental medications which have affected your oral health,
• Prevent drug interactions from occurring, and
• Tailor your treatment to your specific medical needs.

Your prescriptions, over the counter medications, and even herbal supplements and vitamins are essential information. It’s a good idea to make a list before your next appointment at our East Lyme, CT office so you have specific medications and their dosages at hand. It’s one small—but vital—step you can take to work with Dr. James Robson for your best dental health!

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.
