Adults Can Get Cavities Too

December 31st, 2025

Sure, you brush your teeth and floss regularly, so you might think you’re off the hook when it comes to the dental chair. However, it’s just as important for adults to get regular dental exams as it is for kids. Cavities are common among adults, with 92% of people aged 18 to 64 having had cavities in their permanent teeth, according to the National Institute of Dental and Craniofacial Research.

How cavities form

Our mouths are teeming with hundreds of types of bacteria. Some are helpful and maintain good health, while others are harmful. Certain types of bacteria process the sugars in food and release acid in return. Although minor decay can be naturally reversed by your body, Sandra Martin and our team at Sandra Martin Family Dentistry will tell you that eventually the acid wears away the enamel and creates small holes in the surface of teeth.

Cavity prevention for adults

Some people are naturally more prone to cavities than others. However, making a few lifestyle changes can dramatically reduce your likelihood of developing cavities.

  • Food choices. Eating plenty of fresh fruits and vegetables increases saliva production, and reduces cavity risk. It is also important to avoid foods that get stuck in the ridges of your teeth. Candy, cookies, and chips should be eaten sparingly.
  • Beverages. Most people know that drinking soda contributes to tooth decay. However, fruit juices and energy drinks also contain large amounts of sugar. Whenever possible, replace these sugary beverages with tea or water, which rinses your mouth and prevents decay.
  • Fluoridated water. Fluoride is a naturally-occurring chemical that facilitates enamel growth. Most municipal water supplies are fortified with fluoride, so drinking tap water is a great way to keep teeth healthy. People with well water may use fluoridated toothpaste or other supplemental forms of fluoride to decrease cavity risk.
  • Brush teeth and floss frequently. Gently brushing teeth several times a day removes the harmful bacteria that cause cavities to develop. If possible, brush your teeth after each meal or when drinking sugary beverages. Flossing regularly removes small particles that get trapped between teeth, which further decreases tooth decay.

One of the most important steps in cavity prevention is visiting your dentist at least twice a year. Consistent dental exams ensure that cavities are caught early, before they cause major damage to your teeth.

Three Classic New Year’s Resolutions for Your Dental Health —and Three Which Might Surprise You!

December 31st, 2025

Whether you’re using the latest note-taking app or old-school pen and paper, it’s a good time to start jotting down your resolutions for a healthier, happier New Year. To help the process along, we have some suggestions for traditional tooth-friendly resolutions—and also some ideas which might surprise you!

The Classics

  • Brush and Floss Regularly

If you’re sticking to the “two minutes twice a day” brushing schedule as well as flossing once a day, great work! Often, though, that two-minute window starts to shrink as our brushing routine becomes *too* routine. Try timing yourself while you brush normally. If you’re falling quite a bit short of two minutes, taking just a bit more time will be lots more effective in removing plaque from your teeth.

And since gum disease is a leading cause of tooth loss in adults, commit to flossing once a day to remove irritating plaque and bacteria from between teeth and around the gumline.

  • Use Fluoride Toothpaste

Fluoride toothpaste doesn’t just help prevent cavities by cleaning away plaque and food particles. It also helps make our enamel stronger. 

Acids created by plaque bacteria and acids in our diet dissolve minerals from tooth enamel, making it softer and more vulnerable to cavities. Fluoride bonds with the minerals in enamel to create an even stronger protective enamel coating. Check with Sandra Martin or the American Dental Association’s website for the best toothpaste choices for healthy, strong enamel.

  • See Your Dentist Regularly

Dentists typically recommend a full dental exam and cleaning twice each year. Your dental team at Sandra Martin Family Dentistry will take X-rays as needed, examine your teeth, gums, and general oral health, and screen for oral cancer. A professional cleaning will remove any built-up plaque and tartar, which is especially important for gum health.

Being proactive with your dental care means you’ll be sharing your healthy smile all year long—as well as discovering any potential problems before they can develop into major problems!

The Surprises

  • Chew (Sugarless) Gum

When you’re not producing enough saliva, you feel the effects of dry mouth, including sore throat, difficulty swallowing, and bad breath. Another side effect? Poorer dental health. 

Saliva helps neutralize the acidic foods we eat, washes away bacteria and food particles, and contains minerals like calcium and phosphorus which remineralize tooth enamel. Chewing sugarless gum encourages saliva production. If you suffer from dry mouth, check with your dentist to see if chewing sugar-free gum can help.

  • Don’t Brush Right After Eating

Brushing after a meal is great to remove food particles like sugars and carbs which stick to our teeth—and which the bacteria in plaque thrive on. But if you’ve been eating or drinking acidic foods, it’s best to wait about an hour before brushing. 

Acids in foods, like acids created by bacteria, weaken tooth enamel. Brushing right away can be abrasive and damage enamel, but if you wait for an hour, the minerals in saliva have a chance to remineralize and restore your enamel strength.

  • Toss Your Toothbrush

Not that we mean give up brushing altogether! But your toothbrush bristles start to fray and fan out after several months, meaning that you won’t be getting the full cleaning effects of your great brushing technique. Put a note on your calendar to replace your brush every three to four months for the best in plaque removal.

If you’re already following all these suggestions for protecting your dental health, resolve to keep up the good work! If not, give these easy-to-follow recommendations a try. Protecting your dental health is essential to gift yourself a new year filled with happy, healthy smiles in Wake Forrest, North Carolina.

How do I know if I’m at risk for oral cancer?

December 24th, 2025

Every year, over 50,000 North Americans are diagnosed with oral or throat cancer, which has a higher death rate than many other common cancers, including cervical cancer, testicular cancer, Hodgkin’s lymphoma, and thyroid or skin cancers. The high death rate results from the fact that most oral cancers go undiagnosed until the disease is well advanced and has spread to another part of the body, most often, the lymph nodes in the neck.

Because oral cancer is typically painless in its early stages and often goes undetected until it spreads, many patients aren’t diagnosed until they are already suffering from chronic pain or loss of function. However, if detected early, Sandra Martin and our team at Sandra Martin Family Dentistry want you to know that early detection of oral cancer improves the survival rate to 80 percent or more.

If you visit our Wake Forrest, North Carolina office regularly, you have probably received an oral cancer screening and didn’t even realize it. That’s because the exam is quick and painless; Sandra Martin and our team check your neck and mouth for signs of oral cancer such as discolorations, lumps, or any changes to your tissue. Oral cancer is typically found on the tongue, lips, gums, the floor of the mouth, or tissues in back of the tongue.

Factors that may influence your risk for developing oral cancer include:

  • Use of tobacco products. Smoking cigarettes, cigars, a pipe, or chewing tobacco all elevate risk for developing oral cancer. Tobacco use especially is a serious risk factor because it contains substances called carcinogens, which are harmful to cells in your mouth.
  • Excessive consumption of alcohol. Those who drink alcohol regularly have an elevated risk of getting oral cancer. Alcohol abuse (more than 21 drinks in one week) is the second largest risk factor for the development of oral cancer, according to the Oral Cancer Foundation.
  • Excessive sun exposure. Those who spend lots of time outdoors and do not use proper amounts of sunscreen or lip balm have a greater risk for developing lip cancer. Exposure to ultraviolet (UV) radiation from sunlight may also cause melanoma, the most serious type of skin cancer.
  • Your age. Oral cancer is typically a disease that affects older people, usually because of their longer exposure to other risk factors. Most patients diagnosed with oral cancer are over the age of 40.
  • Your gender. Oral cancer strikes men twice as often as it does women.
  • A history with viral infections, such as human papillomavirus (HPV).
  • A diet low in fruits and vegetables.

In between your visits to our office, it is critical for you to be aware of the following signs and symptoms, and give us a call if these symptoms don’t go away after two weeks.

  • A sore or irritation that doesn’t disappear
  • Red or white patches
  • Pain, tenderness, or numbness in mouth or lips
  • Difficulty chewing, swallowing, speaking, or moving your jaw or tongue
  • A change in the way your teeth fit together when you close your mouth

During your next visit, Sandra Martin will examine your mouth for signs of oral cancer. If you have been putting off a visit to our Wake Forrest, North Carolina office for your regular checkup, now is an excellent time to schedule one. Regular visits can be the first line of defense against oral cancer because we can identify early warning signs of the disease. Give us a call today!

Can Toothpaste Repair Tooth Decay?

December 24th, 2025

It seems like the ads are everywhere these days—repair your enamel and reverse tooth decay with a tube of toothpaste! Are these claims too good to be true? Let’s dive into the science of tooth decay—how decay develops and how (and if!) it can be reversed.

Teeth can stand up to the powerful pressures of biting and chewing because over 95% of our enamel is made up of minerals. Calcium and phosphate ions in our teeth bond to form a crystal structure called hydroxyapatite. Because of the strength of this crystalline design, tooth enamel is the hardest substance in our bodies, even stronger than our bones. 

But bones, like most other parts of our bodies, are living tissue, which means that they can create new cells to replace old or damaged cells. Tooth enamel can’t regenerate new cells to repair itself. This means that when a cavity has made a hole in the tooth, the enamel can’t grow back. And, while enamel structure is very strong, it’s also vulnerable to damage—specifically, damage from acids. 

Our teeth are exposed to acids throughout the day, whether they are acids created by plaque bacteria or the acidic foods and drinks we consume. Acids dissolve mineral bonds, stripping calcium and phosphate minerals from the enamel and leaving weak spots in the tooth surface. This process is called demineralization. Demineralization is the first stage of tooth decay.

The good news? Our bodies are designed with a built-in defense mechanism to prevent demineralization from causing lasting damage. All through the day, saliva helps wash away acids in the mouth and bathes our teeth with new calcium and phosphate ions. These ions bond with the calcium and phosphate in our enamel, restoring enamel strength. This protective repair process is called remineralization.

Now for the bad news. In the tug of war between demineralization and remineralization, saliva can only do so much. If your diet is heavy with acids, if you don’t brush away acid-producing plaque bacteria regularly, if you eat a lot of the sugars and starches which feed plaque bacteria, the remineralizing effects of saliva can’t keep up with the demineralizing effects of acids.

The first visible sign of demineralization is often a white spot on the tooth where minerals have been stripped from enamel. Studies have shown that enamel-strengthening toothpaste can be effective in this very first stage of tooth decay. Toothpastes which advertise enamel repair generally contain one or more of these ingredients:

  • Calcium Phosphate
  • Hydroxyapatite
  • Fluoride 

Toothpastes with calcium phosphate or hydroxyapatite contain calcium and phosphate minerals, the building blocks of tooth enamel. Studies have suggested that these minerals can replace the calcium and phosphate ions stripped from enamel. These toothpastes may or may not contain fluoride, which is something you should discuss with your dentist before deciding on a specific toothpaste.

Fluoride toothpastes remineralize enamel—and more! Fluoride ions are attracted to the tooth’s surface, and, when fluoride ions join with the calcium and phosphate ions there, they form fluorapatite. Fluorapatite crystals are larger, stronger, and more resistant to acids than hydroxyapatite crystals. And, once bonded with tooth enamel, fluoride attracts the calcium and phosphate ions in saliva to remineralize the teeth more quickly. 

Why consider enamel-repair toothpaste? 

Once enamel is gone, it’s gone for good. If excess demineralization isn’t treated, a weak spot on the tooth surface will continue to erode, growing bigger and deeper until it becomes a hole in the enamel. This is a cavity, and your dentist will need to treat and repair your tooth to prevent the cavity from growing and potentially exposing the tooth’s pulp to bacteria and infection. 

Talk to Sandra Martin at our Wake Forrest, North Carolina office about which toothpastes can help restore a healthy balance between the ongoing cycles of demineralization and remineralization. While tooth-repair toothpaste can’t fix cavities, these products can often strengthen demineralized enamel and reverse this earliest stage of tooth decay.
