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.

Why Are We Recommending a Periodontal Consultation?

December 17th, 2025

The best way to protect yourself from gum disease is to be proactive: practice good oral hygiene at home and schedule regular checkups and cleanings in our Wake Forrest, North Carolina office.

How do you know if your dental routine is doing the job? There are specific symptoms you might notice when you brush and floss, and less obvious signs of gum disease we look for during your dental exams.

The early stage of gum disease is known as gingivitis. It’s generally caused by poor dental hygiene, although certain diseases, age, hormones, and a number of other factors can also put you at risk. It’s time to talk to Sandra Martin about your gum health if you notice any of these symptoms:

  • Bright red or purple gums
  • Swollen gums
  • Pain or tenderness
  • Bleeding when brushing or flossing
  • Persistent bad breath
  • Receding gums

And sometimes, there are no obvious symptoms at all. That’s why regular checkups are so important. If you have gingivitis, careful attention to your oral hygiene, professional cleaning, prescription mouthwash, or other treatments as needed can reverse the effects of gingivitis and restore your gums to their normal, healthy state.

Why be so proactive? Because, left untreated, gingivitis leads to more serious gum disease, called periodontitis. The bacteria in plaque and tartar cause inflammation, and inflammation leads the gum tissue to pull away from the teeth, forming pockets which become deeper over time. Here, where brushing can’t reach, bacteria continue to multiply, leading to further inflammation, infection, and the eventual breakdown of gum and bone tissues.

The results of untreated periodontitis can be very serious, including:

  • Significant gum recession, leaving roots more vulnerable to decay
  • Periodontal abscesses
  • Loose teeth, or teeth that shift from their proper positions
  • Bone loss in the area surrounding the teeth
  • Tooth loss

If we see signs of advanced periodontitis, we may refer you to a periodontist.

Periodontists specialize in the diagnosis, prevention, and treatment of gum disease. After dental school, a periodontal degree requires three years of additional advanced education. Periodontists have the training and skill to perform surgical and non-surgical procedures to treat gum disease, as well as to perform cosmetic procedures and place dental implants.

Periodontists are trained to diagnose and treat periodontitis with a number of procedures which they will recommend based on your specific needs. Among the treatments they provide to restore your gum health:

  • Topical, time-release, or oral medication
  • Scaling and root planing, non-surgical deep cleaning procedures which remove plaque and tartar above and below the gumline, and smooth tooth roots to remove bacteria and help the gum tissue reattach to the teeth
  • Flap surgery to treat persistent gum infection, reduce pocket depth, and re-secure the gums snugly around the teeth
  • Bone grafts, gum grafts, and other regenerative procedures which help restore and repair tissue damaged by gum disease

If we recommend a periodontal consultation, be proactive. The best way to protect yourself from the significant consequences of untreated gum disease is to see a specialist in this field. Your periodontist has the knowledge and experience to stop gum disease from progressing, treat damaged bone and gum tissue, and restore your healthy smile.

The History and Mythology of the Tooth Fairy

December 17th, 2025

While the last baby teeth generally aren’t lost until age ten or 11, most children stop believing in the tooth fairy by the time they're seven or eight. Of course, children are more than happy to play along with the game when there’s money at stake! While it is impossible to know what the tooth fairy does with all those teeth (are they labeled and stored like museum pieces in a giant fairytale castle?), it is possible to trace the history and myth of the tooth fairy to several cultures and traditions. Sandra Martin and our team learned about some interesting myths about the tooth fairy!

The Middle Ages

Legend has it that Europeans in the Middle Ages believed a witch could curse someone by using their teeth, so it was important to dispose of baby teeth correctly. Teeth were swallowed, buried, or burned. Sometimes baby teeth were even left for rodents to eat. Despite being pests, rodents were valued for their strong teeth; it was generally believed a tooth fed to a rodent would lead to the development of a healthy and strong adult tooth.

Eighteenth Century France

The tooth fairy myth began to show more characteristics of a conventional fairytale in 18th century France. La Bonne Petite Souris, a bedtime story, tells the strange tale of a fairy that changes into a mouse to help a good queen defeat an evil king. The mouse secretly hides under the evil king’s pillow and defeats him by knocking out his teeth.

Scandinavian Lore

So, why does the tooth fairy leave money under the pillow? The idea of exchanging a tooth for coins originated in Scandinavia. Vikings paid children for a lost tooth. Teeth were worn on necklaces as good luck charms in battle. While the idea of exchanging a tooth for coins quickly spread throughout the rest of Europe, a fierce, horn-helmeted Viking is far cry from the image of a fairy collecting teeth.

While the tooth fairy as children know her today didn’t make an appearance until the 1900s, tooth myths and rites of passage have existed in numerous cultures since the dawn of time.
