Getting a cavity seems like delayed punishment for eating that special dessert every weekend or for the few days you forgot to floss. When you are doing everything right with minimal exception and a cavity is diagnosed, it is discouraging. Knowing how cavities form and what causes them is valuable in knowing how to prevent them. In this blog post, Dr. Janaki Narayanan will help you understand cavities!

A cavity is not a one-time event. It is actually a symptom of a disease called caries. Tooth decay is a result of an active infection and condition in the mouth. There are ingredients to this infection, which include bacteria, acid, your tooth, and a food source. The main bacterial culprit is S. Mutans. Bacteria live in a housing structure called biofilm. This offers them protection, food, and an ideal replicating environment.

Biofilm can be healthy if there is a balance of good bacteria. When you have caries, the numbers of “bad” bacteria increase and produce an environment where they thrive and therefore cause tooth decay. A main indicator of this is a pH measurement of your saliva.

Several factors can influence the biofilm pH. Foods and beverages all have different pH levels. The lower the number, the higher the acidity. Since acid promotes tooth decay, a beverage like soda will promote a cavity. Water, being neutral, is a good choice to promote healthy oral pH. Healthy eating can still cause cavities. Here is an example of a highly acidic, yet traditionally healthy meal:

Toast with store-bought strawberry jam, and a cup of cottage cheese topped with fresh cranberries.

Instead, here is a better choice, which involves mixing acidic healthy foods with alkaline (non-acidic) foods to reduce the overall pH:

Toast with almond butter, and Greek yogurt topped with fresh blueberries.

The first example will result in a very low pH in the mouth and even in the rest of the body. The second meal mixes highly acidic blueberries with an alkaline Greek yogurt. Dairy products from cows are highly acidic. Toast is acidic because of the yeast and almonds are alkaline.

A natural buffer is saliva. Whenever mouth breathing or medications compromise the saliva flow, the pH is going to drop and caries can go rampant. Getting a cavity is not just about the sweets or forgotten flossing sessions. It is about the pH levels and bacterial management.

Regular visits to the dentist are important for people of all ages. Seeing Dr. Janaki Narayanan as recommended provides preventive care for oral diseases. If a disease is already present, early detection can prevent hefty dental bills and further damage to the teeth and gums. Once you have made the decision to visit Great Smile Dental, you may ask yourself, “What happens during my hygiene appointment?”

Preparation

Arrive at your appointment a few minutes early and bring along any insurance cards or medical information. While it may seem irrelevant, a full medical history can be important, since certain conditions include symptoms that occur inside the mouth.

Initial appointment

In some offices, the first appointment is a screening appointment, during which a dental hygienist will go over your medical and dental history with you, assess the condition of your teeth and gums, then schedule a future appointment to complete the cleaning and any other treatments you may need. In other offices, the screening and cleaning will be done over the same appointment. The dental hygienist may:

• Count your teeth
• Clean your teeth by using a small tool to scrape them in order to remove plaque
• Brush and floss your teeth
• Apply a fluoride treatment using foam that sits on your teeth within a tooth mold, or a gel that can be “painted” on with a small brush
• Inspect your teeth for cavities or signs of decay
• Administer oral X-rays. You will be covered with a special blanket to protect your body and then given a small piece of plastic on which to bite.

Seeing the dentist

After the dental hygienist completes his or her portion of the appointment, the dentist will usually come in and inspect your teeth. After an initial inspection, the dentist may:

• Perform a quick tooth count as well as a more thorough inspection, looking for signs of decay in and around the teeth
• Use a small tool called a “probe” in order to check for signs of gum disease around the base of your teeth
• Visually inspect the skin around your mouth, called the “mucosa”

If you need any further dental work completed, you will usually be required to make an additional appointment. To learn more about hygiene visits, or to schedule an appointment with Dr. Janaki Narayanan, please give us a call at our convenient Duvall office!

At Great Smile Dental, we love to celebrate the holidays with vigor! Dr. Janaki Narayanan would love to share some unique ways of celebrating Thanksgiving from beyond the Duvall area to the national level!

When Americans sit down to dinner on the last Thursday of November, the day that Abraham Lincoln designated as the day on which Thanksgiving would be celebrated, they do so thinking that the first Thanksgiving feast was held at Plymouth in 1621. According to National Geographic, the Spanish explorer Francisco Vásquez Coronado and his men celebrated a feast of Thanksgiving in Texas in 1541, giving Texas the distinction of being the first place where Thanksgiving was celebrated.

Different Types of Celebrations

Native Americans had rituals around which they celebrated in hopes of ensuring a bountiful harvest. The Cherokees had a Green Corn Dance that they did for this very purpose. The Pilgrims (not to be confused with the Puritans,) rejected any type of public religious display. They held a three-day long non-religious Thanksgiving feast. Although they said grace, the focus of their celebration was on feasting, drinking alcohol (they did have beer,) and playing games.

The Pilgrims at the Plymouth Plantation celebrated a different day of Thanksgiving in 1623. Plagued by a crop-destroying drought, the settlers prayed for relief. They even fasted. A few days later, they got the rain they so desperately needed. Soon thereafter, they received another blessing when Captain Miles Standish came with staples they couldn't otherwise get. He also told them that a Dutch supply ship was en route. In gratitude for the abundance of good fortune, the Plymouth settlers celebrated a day of prayer and Thanksgiving on June 30, 1623.

The Story of Squanto

No discussion of Thanksgiving is complete without a discussion of Squanto, or Tisquantum, as he was known among his people, the Patuxet Indians. It is believed that he was born sometime around 1580. As he returned to his village after a long journey, he and several other Native Americans were kidnapped by Jamestown colonist, Thomas Hunt. Hunt put them on a ship heading to Spain where they were to be sold into slavery.

As fate would have it, some local friars rescued him and many of the other kidnapped natives. Squanto was educated by the friars. Eventually, after asking for freedom so he could return to North America, he ended up in London where he spent time working as a ship builder. By 1619, he was finally able to get passage on a ship headed to New England with other Pilgrims.

Upon arriving at Plymouth Rock, he learned that his entire tribe was wiped out by diseases that accompanied earlier settlers from Europe. In gratitude for passage on their ship, he helped them set up a settlement on the very land where his people once lived. They called the settlement Plymouth. Since they knew nothing about how to survive, let alone how to find food, Squanto taught them everything, from how to plant corn and other crops, how to fertilize them, how and where to get fish and eels and much more.

After a devastating winter during which many settlers died, thanks to Squanto's teaching, they had an abundant harvest. After that harvest, they honored him with a feast. It is this feast of 1621 which was celebrated between the Pilgrims and Wampanoag Indians that is widely considered the first Thanksgiving celebration.

About the Meal of the Plymouth Settlers

Surviving journals of Edward Winslow that are housed at Plymouth Plantation indicate that the first Thanksgiving feast was nothing like what Americans eat today. The meal consisted of venison, various types of wild fowl (including wild turkey,) and Indian corn. There were no cranberries, stuffing, pumpkin pie, potatoes, or any of the other “traditional” foods that appear on modern menus.

Today, Thanksgiving is celebrated on the fourth Thursday of November, the day that Abraham Lincoln designated as the holiday. It is still a day of feasting, and for some, a day of prayer and thanksgiving. For others, it is a celebration of gathering, especially for families. Still others may celebrate in entirely different ways, including watching college football bowl games, or by playing family games.

If you ever wonder why you're so tired after the Thanksgiving meal, it's because turkey contains an amino acid, tryptophan, and it sets off chemicals whose chain reaction combine to make people sleepy.

Cigarette smoke contains more than 6,000 chemicals, and at least 200 of those chemicals are known to be harmful to your health. When smoke is inhaled, moist oral tissues are saturated with excessive amounts of carbon monoxide, hydrogen cyanide, and a host of other known carcinogens. Most oral cancers originate in abnormal squamous cell activity, which are cells found on the lips, inside the mouth, and in the throat.

How Oral Cancer Begins

Cells exposed to consistently high levels of cigarette smoke may eventually suffer abnormal mutations within their DNA. Since deoxyribonucleic acid (DNA) is responsible for providing cells with instructions about growth, reproduction, and death, these instructions become distorted, which causes the cells to reproduce uncontrollably.

Essentially, that is what cancer is: rapid, unchecked growth of genetically mutated cells that encourages the development of malignant tumors. Unfortunately, the chemicals in cigarette smoke are strongly associated with oral cancer.

Signs of Oral Cancer

Early-stage oral cancer is often asymptomatic, which means symptoms appear only after the cancer intensifies and spreads. Possible signs of oral cancer include:

• Ulcers inside the mouth or on the lips that do not heal
• White or dark red patches inside the mouth
• Lumps inside or around the mouth (a lump could appear on your neck)
• Bleeding, numbness, and soreness in the mouth
• Chronic halitosis
• Loose teeth in the absence of tooth decay

Diagnosis and Treatment of Oral Cancer

Squamous cell oral cancer is the most common type diagnosed in smokers. Dr. Janaki Narayanan and our staff often discover squamous cell carcinoma lesions during dental examinations or cancer screenings. Depending on the stage of the oral cancer, treatment may begin with a biopsy or an exfoliative cytology procedure that involves collecting cells from the oral cavity using a scraper.

According to the Oral Cancer Foundation, oral cancer patients may need surgery, radiation therapy, a combination of surgery and radiation therapy, or chemotherapy to eradicate oral cancer.

Smoking, Cancer, and Tooth Decay

Not only is smoking the number-one cause of cancer but it is also detrimental to the overall health of your teeth and gums. Yellow teeth, bad breath, dry mouth, and expedited tooth decay are all caused by smoking, not to mention the damage smoke does to the heart, lungs, and kidneys.

In other words, don’t smoke!
