You’re busy getting ready for your day, and of course you’re starting your day off right by looking after your dental health. A two-minute brushing, some careful flossing, and—wait, is that a white spot on your tooth?

If your mirror reveals a patch of white on your enamel, it could be a symptom of early tooth decay.  Does this mean a cavity is necessarily in your future? Perhaps not, if you act promptly to reverse the damage!

Cavities, after all, don’t suddenly appear in our mouths. Tooth decay is a process, and it begins with a weak area in the enamel that often appears as a white spot on the tooth. These weak spots are known as “incipient cavities,” because they can easily become cavities if left untreated.

Why do these weak spots occur? And how can we repair them? Let’s look at some tooth science.

• Demineralization

Your tooth enamel is one of the marvels of the human body. Enamel is mostly made of calcium and phosphate ions, minerals which combine to form hydroxyapatite crystals. These crystals create a substance so strong that tooth enamel is the hardest part of the body—harder even than bones.

But it’s not indestructible! If you don’t care for your teeth with regular brushing and flossing, you’re leaving your enamel open to attack.

The bacteria in plaque convert the nutrients they get from the food we eat—especially sugars—into acids. These acids strip away the calcium and phosphate minerals which are the building blocks of our enamel, weakening the surface of the tooth.

Over time, these weak spots get bigger and deeper as bacteria and acids continue to attack the tooth surface. Eventually, cavities form, damaging the enamel surface, and, over time, even reaching into the dentin and the pulp inside the tooth. Once a cavity has formed, you need dental treatment to clean away the decay and repair the tooth structure.

The good news is that, when caught early, it’s possible to rebuild a weak spot in the tooth enamel before a cavity can fully develop.

• Remineralization

While acids strip minerals from your enamel, your body is also replacing those lost minerals all throughout the day. How does this balancing act take place? With the help of saliva.

The very minerals which acids strip from your enamel are found in saliva. Saliva bathes your teeth with calcium and phosphate ions which, in turn, bond with your enamel to rebuild and restore enamel strength. When missing minerals are replaced like this, it’s called remineralization.

But this careful balance of demineralization/remineralization can become upset. If you neglect brushing and flossing, for example, plaque buildup will increase the amount of acids your teeth are exposed to. This means that your body won’t be able to replace the minerals as quickly as they are stripped away, and the result is a white patch on your tooth where the enamel has lost mineral strength.

If you’re surprised by the appearance of a white spot on your tooth, it’s a good idea to visit our Ashland office for a diagnosis. If the spot is caused by an incipient cavity, Dr. John Zarrella and Dr. Peter C. Rider can provide you with some options to restore your enamel’s strength.

Fluoride toothpastes and fluoride treatments are some of the most efficient ways to remineralize your teeth. Fluoride is attracted to the minerals in your enamel. It bonds with the tooth surface, and, once there, it helps attract the calcium and phosphate ions in your saliva to restore lost minerals and repair weak spots.

But fluoride does more than just restore your tooth’s strength—it improves it! Fluoride ions join with the calcium and phosphate minerals in your teeth to form fluorapatite crystals, which are even larger and stronger than hydroxyapatite crystals.

Early treatment is your best opportunity to reverse the early stages of tooth decay. Keeping up with your brushing and flossing, eating a dental-healthy diet, seeing Dr. John Zarrella and Dr. Peter C. Rider regularly, and treating incipient cavities promptly will help ensure there are no unwelcome surprises in the mirror—just beautiful, healthy smiles!

Have you ever wondered why people have wisdom teeth? These are a third set of molars that come in behind the rest of all your other teeth, usually during early adulthood. Scientists and anthropologists believe that wisdom teeth are a result of evolution, because our ancestors needed these extra teeth to handle their primitive diets. Nowadays, the average diet consists of fewer hard-to-chew foods, which renders wisdom teeth largely superfluous.

Most people begin to experience wisdom teeth pain between the ages of 17 and 25. Our ancestors nicknamed them wisdom teeth because they appeared at a time in life when we supposedly grew wiser.

If you’ve already had your wisdom teeth removed, you know how painful they can become if they aren’t taken care of promptly. If not, watch out for discomfort in the back of your mouth and let Dr. John Zarrella and Dr. Peter C. Rider know right away if you think your wisdom teeth are coming in.

In some cases, people do not experience any problems or discomfort with their wisdom teeth. These patients may keep their wisdom teeth intact if there’s enough room in their jaw to fit them properly. But this is generally not the case, so wisdom teeth can cause several concerns, depending on which direction they grow.

Common problems include:

• Damage to surrounding teeth due to the pressure from the emerging teeth
• Infection that causes the surrounding gums to swell and become painful
• Tooth decay due to the lack of room to clean the teeth properly
• Impaction (when the tooth is unable to break through the skin)
• A cyst that may damage the jaw, the surrounding teeth, and nerves

If you haven’t had your wisdom teeth removed yet, there are many symptoms to watch out for when they begin to grow. Symptoms may include:

• Pain or stiffness in the jaw
• Tooth irritation
• Swelling of gum tissue
• Crowding of other teeth
• Spread of tooth decay or gum disease on nearby teeth

If you’ve noticed these symptoms, schedule an appointment at our Ashland office. Don’t forget: This is a common procedure that will take some time to recover from. Allow your mouth to heal, and then you’ll be able to get back to a normal routine quickly and be free from pain!

Sealants offer many benefits, but the best is their ability to protect your molars. Molars are full of small caverns that can be the perfect breeding ground for tooth decay and plaque buildup.

Use of protective sealants prevents this buildup from happening. Although children often receive sealants for routine preventive care, they aren’t the only ones who can benefit from this treatment. Sealants can also help adults who have deep canyons or grooves in their teeth.

They are commonly placed on the rear molars that tend to suffer the most decay. Because your molars are used substantially as grinding surfaces, food is more likely to be trapped among them.

Sealant solution consists a composite material that contains bonding agents that seal the top of your teeth. The process is quick and painless, which makes it a great solution for both children and adults who have had trouble with cavities and tooth decay. Sealants also last for several years, and repair is a simple process that can be completed by Dr. John Zarrella and Dr. Peter C. Rider.

The process of putting sealants on teeth starts with the tooth getting cleaned. We clean it with a type of baking soda spray called sodium bicarbonate. Then acid is etched onto the teeth to rough up the surface.

We apply an alcohol-based liquid to dry the area where the sealant is supposed to go. After it completely covers the surface of the treated teeth, the sealant is cured with a light that makes it hard and long-lasting.

Getting sealants can prevent the possible restorative costs that come from cavities. Sealants help to protect your tooth’s enamel from harmful acids and prevent decay, which can be an investment in itself. The whole process is quick, so it should be easy to schedule an appointment at Zarrella Dentistry.

You’ve heard people tell you to say “cheese” when you’re having your picture taken, probably more times than you can count. There is another reason you should be saying “cheese” … or “YES” to eating cheese.

Although Dr. John Zarrella and Dr. Peter C. Rider and our staff routinely encourage our patients to brush their teeth after eating, the one time you don’t want to do that, at least not immediately, is after eating cheese.

Study Finds Important Benefit From Eating Cheese

CBS News reported on the results of a study that was published in the May/June 2013 issue of General Dentistry, a publication of the Academy of General Dentistry. The study showed that cheese increases dental plaque pH, but in this case, the plaque increase isn’t a bad thing. When you eat cheese, you increase the pH of the plaque on your teeth, and create a protective coating that may lower your risk of getting dental caries -- more commonly known as cavities.

An analysis of the story from the General Dentistry journal, including the details of the study and its participants, was published in Science Daily. The study looked at 68 children between the ages of 12 and 15. A similar study was conducted by British researchers who reported their findings in the British Dental Journal in 1999.

How the Study Worked

For the 2013 study, researchers divided kids into three groups. Participants in group one ate cheddar cheese. Participants in group two drank milk, while participants in group three ate sugar-free yogurt. All participants were told to eat or drink their assigned foods for three minutes, after which they swished water in their mouths.

Researchers tested every participant’s mouth at ten, 20, and 30-minute intervals. They found no changes in the mouths of participants in the milk drinking and sugar-free yogurt eating groups, but every time they tested the pH levels in the mouths of the ones who had eaten cheese, researchers saw the levels quickly increased.

They concluded that cheese has anti-cavity properties. That isn’t the only benefit, however. Another study, in which related findings were reported, appeared in the Journal of Contemporary Dental Practice in the summer of 2000. In that study, researchers found that cheese may give teeth a protective coating that helps lessen enamel erosion caused by acidic foods, particularly from sugar-sweetened soft drinks.

So don’t just say cheese for pictures. If you want to have a happy, healthy and long-lasting smile, go for cheese. It’s good for your bones, too!
