Root Cavities

April 9th, 2025

When we don’t keep up with our dental hygiene, plaque buildup can result in three kinds of cavities. Pit and fissure cavities are found on the tops of molars, where food particles get stuck in the irregular surfaces. Smooth surface cavities are located on the smooth sides of teeth.

Wait. Top, all around the sides—what’s left for plaque to attack?

Our roots. The roots of our teeth are generally protected by their concealed position in the jaw. Sitting securely in alveolar bone, held firmly in place by connective tissue, with gum tissue snugly surrounding them, roots are generally not cavity prone.

But these cozy conditions can change. Due to gum disease, abrasive habits, or simply the passage of time, gums can recede and expose root surfaces. And this exposure can lead to root cavities.

If you look at a complete tooth, it looks like enamel is covering the entire tooth surface. In fact, enamel, the strongest substance in the body, only covers the visible part of the tooth, called the crown. The roots are covered by a substance called cementum, which is softer than enamel. And if enamel can’t stop decay, cementum is even more vulnerable when it’s exposed to plaque, bacteria, and acidic foods.

How do we protect our roots from decay? Protecting our gums is the first line of defense.

  • Gum Disease

Receding gums caused by periodontitis can be treated by Dr. Osuala. Deep cleaning procedures such as scaling and root planing can remove accumulated plaque and tartar, and help gum tissue reattach to teeth. For serious recession, gum grafts can replace lost tissue.

Early treatment can prevent recession. If you notice any signs of early gum disease, including bleeding, swelling, tenderness, or persistent bad breath, it’s time for a visit to our Maplewood & West Orange office.

  • Gum Abrasion

It’s not just gum disease that can lead to gum recession. Some personal habits are hard on gums and teeth, and can leave roots exposed. If you bite your nails, grind your teeth, irritate your gums with oral piercings, you are at risk for gum recession. Talk to Dr. Osuala about preventing abrasive damage.

A surprising cause of receding gums? Over-vigorous brushing. Use a soft-bristled brush—and don’t use a heavy hand when brushing—to protect your delicate gum tissue.

  • Aging

As we age, our gums recede. So it’s no wonder that older adults are especially at risk for root cavities. That’s why it’s very important to keep up with brushing (at least two minutes twice a day) and flossing (once a day, or more often if needed) to prevent the buildup of plaque and tartar.

And it’s more important than ever to schedule regular dental exams and cleanings. Dr. Osuala can help stop small problems from becoming major ones, and suggest brushing and flossing techniques, fluoride treatments, or other procedures to encourage gum and dental health.

If a cavity develops, no matter what kind, it should be treated as soon as possible. And time is especially important for a root cavity.

Because cementum is weaker than enamel, cavities can progress more quickly in roots. A cavity which has reached pulp tissue might require a root canal and a crown to restore tooth function. Serious decay could lead to extraction.

Don’t let root cavities undermine your dental health. If you notice any sign of gum disease or recession, it’s time for a visit to our Maplewood & West Orange office. After all, even though they go unnoticed, strong roots are the foundation of a healthy, attractive, life-long smile.

Do Spring Allergies Mean (B)Looming Dental Problems?

April 2nd, 2025

April showers bring May flowers, and May flowers bring . . . allergies. If you’re one of the millions of people who suffer from seasonal allergies, you might be suffering some dental side effects as well.

When you have pollen allergies, pollen triggers your body’s immune system to release histamines. Histamines are part of the body’s defense system. They cause the tissues in the nose and sinuses to become inflamed and swollen as they increase blood supply to these areas. They also cause your body to produce more mucus.

Normally, mucus from the sinus cavities drains into the nasal cavity and then down the back of the throat, where it mixes with saliva and is swallowed. We never even notice it. Until it’s allergy season. Unfortunately, our defense mechanisms can have some offensively unpleasant consequences.

  • Headache & Facial Pain

Our sinus cavities are small hollow spaces in the bones of the head which are filled with air and, like our nasal cavities, are lined with mucous membranes. It’s these membranes, not surprisingly, which produce mucus. And though we might turn up our noses at this slippery topic, mucus is actually quite helpful for trapping and filtering out unwanted hitchhikers like bacteria, viruses, dust, pollens, and other pollutants in the air we breathe before they reach our lungs.

When histamines are released, normal mucus production increases to filter out those tiny pollen invaders. At the same time, tissue around the nose and sinuses swells up, which can trap mucus inside the sinus cavities. This, in turn, causes increased pressure within the sinuses, and this pressure brings on allergy-related headaches and facial pain.  

  • Nasal Congestion & Postnasal Drip

With the occasional runny nose or sneeze, you can blow your nose once or twice and that’s that. During allergy season, greatly increased mucus production might see you spending all day within reaching distance of your box of tissues. But when the tissue in your nose is swollen as well, you now find yourself with nasal congestion.

A stuffy nose means excess mucus has to exit somewhere else, which means this extra, often thicker, mucus all drains into the back of your throat. This is postnasal drip, and it can make you miserable in several different ways. Hoarseness. Coughing during the day. Worse coughing at night. Sore throat. Nausea. Difficulty swallowing.

All these allergy symptoms are uncomfortable enough! But, to add to our discomfort, allergies can lead to uncomfortable oral symptoms as well.

  • Tooth Pain

A common result of allergies is tooth pain. How does this happen? It’s because of the way our bodies are designed. The maxillary sinus cavities are directly above the roots of our upper molars.

When sinus cavities are congested and sinus pressure builds up, it also puts pressure on these roots. The result is tooth pain, usually affecting several upper molars at once.

  • Dry Mouth

One of the natural responses to a stuffy nose is mouth-breathing—we can’t go without air, after all! But exposing the inside of the mouth to all that air dries out delicate gum and mouth tissues. It also reduces normal saliva flow. This can cause xerostomia, more commonly known as dry mouth.

Because saliva neutralizes acidity in the mouth and washes away bacteria and other germs, lower saliva production means greater risk of cavities, infections, and bad breath. Dry mouth can also cause gum irritation and gingivitis, because less saliva means more harmful bacteria build-up between the gums and the teeth.

  • Antihistamines & Your Oral Health

If histamines are the problem, are antihistamines the obvious solution? This is a good question for Dr. Osuala or your physician. Antihistamines can be very drying—so you might find you’re experiencing dry mouth even when all those other pesky allergy symptoms have disappeared. And, if you already suffer from xerostomia, it’s especially important to get your doctor’s advice before buying over the counter antihistamines.

In allergy season, just like any other time of the year, be sure to hydrate and keep up with brushing and flossing for fresh breath and healthy teeth and gums. Talk to Dr. Osuala if you have persistent tooth pain, dry mouth, or irritated gums—it’s always best to rule out other causes like infection or decay.

But, if your problems are caused by allergies, you don’t have to wait until the next snowfall to get relief. Talk to your doctor or allergist for ways to reduce or eliminate your symptoms before allergy problems start blooming into dental problems. You’ll breathe easier!

Is there a connection between oral health and school performance?

March 26th, 2025

As a parent, you want the best for your children, and that includes doing their best in school. You can support them by taking an interest in their activities, being enthusiastic about attendance, and helping them with homework. There may also be one more way you can help your children succeed at school. Surprisingly, research suggests that children with better oral health are likely to do better in school.

What the Research Says

One study in North Carolina looked at risk factors for poor school performance among school-aged children. As expected, the study found poor school performance linked to low socioeconomic status, low levels of parental education, and poor overall health. However, it also found a strong link between poor oral health and poor school performance, with children classified as having poor oral health 40 percent more likely struggle in school.

These findings are generalizable to the rest of the country. For example, attendance is an important factor in academic achievement, but dental conditions are responsible for a loss 51 million school hours among schoolchildren each year. Dental pain and infection are linked to poorer performance.

School-Based Programs to Promote Oral Health

In light of the apparent benefits of good oral health for school performance, some schools are taking steps to promote better oral care and health. In Maine, for instance, schools in need can apply for grants through School Oral Health Program (SOHP). The SOHP consists of four components:

  1. Oral health education for all children to support healthy behaviors
  2. A weekly fluoride mouth rinse to strengthen teeth
  3. Dental screenings to identify children who may need dental care
  4. Dental sealants, or plastic coatings, on back teeth to guard against decay

The State of Maine also supports an “Annual Sugar Out Day” to raise awareness of the effects of sugar on dental health and to help students choose low-sugar alternatives.

Oral Health Habits to Adopt

You can help your child improve oral health and do better in school by encouraging good oral hygiene. This includes brushing at least twice a day with a fluoride-containing toothpaste, and reminding your child to drink water after eating. Also, regular trips to our Maplewood & West Orange office can help prevent serious tooth problems.

Balancing Act

March 19th, 2025

We’re all trying to find a healthy balance in our lives. Balancing work and home life. Eating a well-balanced diet. Balancing our budgets. Maintaining the right pH balance in our mouths for better dental health. Wait, what was that last one?

You probably don’t spend a lot of time thinking about your pH levels, but if your oral pH is out of balance it can affect the health of your teeth.

What do we mean by pH levels? In biology and chemistry, the pH scale is a tool used to measure the concentration of hydrogen (H⁺) ions and hydroxide (OH⁻) ions in a solution.  

The higher the concentration of hydrogen atoms, the more acidic a solution. The higher the concentration of hydroxide ions, the more alkaline. The pH scale goes from 0 to 14, with the most acidic reading possible rating a 0, and the most alkaline, a 14.

You don’t have to be a biochemist to use the information provided by pH samples. We use pH readings to discover the ideal acid/alkaline conditions in many everyday applications. Azaleas grow best in very acidic soil. Swimming pools should be just a bit alkaline. Brewers test pH throughout the beer-making process for optimal fermentation—and taste.

When it comes to saliva, a neutral pH range of around 6.2 to 7.6 is generally considered normal. High alkalinity in saliva is rare. High acidity levels? Unfortunately, much more common. And an acidic environment has real-world consequences for teeth.

Plaque contains bacteria, which produce acids. Calcium and phosphate, the minerals that help make enamel the strongest substance in the body, are leached out by these acids. The weak spots left behind make enamel vulnerable to further erosion and, eventually, decay. When saliva has a normal, neutral pH, it helps neutralize plaque acids to reduce the risk of cavities.

But it’s not just bacteria that expose our teeth to acidic conditions—we do it ourselves with our choice of food and drink.

Acidic foods can directly lower the pH level in saliva. Lemon juice, for example, has a pH between 2 and 3. Red wine has a pH between 3 and 4. Blueberries? Around a 3.2. When the pH level in saliva becomes 5.5 or lower, the minerals in our teeth start to “demineralize,” or lose the minerals which keep enamel strong and intact—just the way enamel is demineralized by acids from plaque. This process is known as acid erosion.

Many of our favorite foods are acidic to some degree. Citrus and other fruits, pickled foods, vinegar, wine, coffee, tea—all of them can lower the optimal pH level of saliva. And sports drinks, energy drinks, and sodas? Check the labels and you’ll often find citric acid, phosphoric acid, and/or carbonation, all of which combine to create extremely erosive conditions.

So, no more soda? Or fruit? No. You don’t have to give up acidic foods altogether for healthy teeth. True, you won’t give up much eliminating soda from your diet. But fruits, vegetables, dairy foods, and meats are the source of essential vitamins, minerals, and proteins, and many of these healthy food choices have an acidic pH. How to eat nutritiously while protecting your enamel? Again, it’s a balancing act.

  • Enjoy acidic foods sparingly, or as part of a meal. Saliva can neutralize acids more effectively when they aren’t washing over your teeth all through the day.
  • Use a straw when you drink something with a low pH to reduce your enamel’s exposure to acids.
  • Balance high-acid foods with low-acid choices to help neutralize the acids in your diet. Add a banana to your blueberry smoothie. Pair your wine with some cheese.
  • Rinse with water after eating or drinking. When it comes to balanced pH, pure water is a 7.0 on the scale, a perfect neutral.
  • Chew sugarless gum to increase saliva production.
  • Use fluoride toothpaste—it not only helps prevent cavities, it helps remineralize teeth.

Even with your best efforts, acid erosion can be a problem. You might be experiencing enamel damage if you notice any of these symptoms:

  • Tooth pain or sensitivity.
  • Teeth that appear discolored. This happens as the whiter enamel thins, revealing the yellowish dentin underneath.
  • Changes in the shape of your enamel—your teeth become rounded or have little dents or pits, known as cupping.
  • White spots on your teeth, which could be a sign of demineralization.

If you think you could be suffering from enamel erosion, it’s a good idea to talk to Dr. Osuala when you visit our Maplewood & West Orange office. We can diagnose conditions causing acid erosion, treat you if enamel damage has occurred, and offer suggestions for diet and eating habits to make sure your oral pH—and your dental health—is always in balance.
