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. Ghenta 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. Ghenta 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!

A strong, healthy smile is built on a strong, healthy foundation. Let’s take a moment to explore just what creates that foundation—your roots.

The Root of the Matter

The visible part of your tooth is called the crown. And while we spent the great majority of our time thinking about what goes on above the gum line—brushing, flossing, whitening, sealing, preventing cavities—the roots, the parts of the teeth below the surface, are also essential to our dental health.

• What’s inside the root?

The inside of each tooth holds pulp, which is living tissue made of nerves, blood vessels, and connective tissue. The nerves in the pulp allow us to feel pain when a tooth is damaged, decayed, or infected. Tiny blood vessels provide oxygen and nutrients to the cells.

The inside of each root also contains pulp, located in one or more root canals. These canals are small tunnels that travel from the pulp chamber to the tip of each root. Nerves and blood vessels connect pulp tissue to the nervous and circulatory systems in the body, entering and exiting the tooth from very small openings in the root tip.

• What’s outside the root?

On the outside, while roots look like crowns, they’re covered with a different protective surface. Roots are covered by cementum rather than enamel. This is a hard tissue, but not as hard as enamel. But cementum has another advantage—it not only helps protect our teeth, it helps them stay anchored in our jaws. (More on this below.)

• How many roots are we talking about?

The number varies, not just depending on the tooth, but depending on the individual. Most adults have 32 adult teeth: eight incisors, four canines, eight premolars, eight molars, and four wisdom teeth, or third molars. Because the number of wisdom teeth can range from four to zero, though, that total can be smaller.

Rooted to the Spot

The reason that you can rely on your teeth for a lifetime of chewing, biting, and grinding food is the fact that they’re so securely anchored in the jaw.

• Alveolar bone in the jaw contains a socket for each tooth.

• A thin layer of connective tissue called the periodontal ligament lines the socket and surrounds each root. It’s filled with fibers that attach to the root’s cementum covering and to the alveolar bone, holding the tooth securely in place.
• The periodontal ligament not only anchors the tooth, it cushions it from the daily pressure of biting and chewing.
• Finally, the gums surround the teeth and bone, protecting them from bacteria and plaque.

Even though this design is very secure, there are situations where the root becomes vulnerable. In that case, you should see Dr. Ghenta at our Dartmouth, MA office right away. Our goal is for you to keep your teeth healthy and strong, and for a lifetime!

The earliest endeavors for dental implant tooth substitutes on record dates back to the Mayan civilization, to 600 AD. Archeologists recovered primeval skulls in which the teeth had been replaced with materials the ranged from wood, stones, and jewels to small pieces of seashells.

Like most scientific progresses, the finding of what makes todays dental implants so successful was unexpected. In 1952, a Swedish orthopedic surgeon, named Dr. Branemark, placed a very small titanium cylinder into a bone to learn how the bone would heal. What he discovered was that the titanium cylinder had fused (melded to the bone.) Out of this experiment dental implants would be born within two decades.

In 1970s, modern dental implants made their first appearance. Of course, over the past four decades, the original dental implant has undergone several improvements in both structure and design, but has always been based on the original theme.

Dental implants were first made available to individuals who had lost all of their teeth and had difficulty wearing dentures, mainly because they had lost of much of their jawbone were dentures set. Today, most dental implants are used in place of dentures, for multiple teeth that are missing, or to replace a single tooth.

When dental implants were first designed, they were a one size fits all. The original dental implants were all the same circumference, while the length of each tooth varied depending on the type of tooth it was replacing. The dental implants were smoothed out and polished by a machine, but still did not produce the natural looking dental implants we have today.

Now, with the help of state-of-the-art equipment and advanced technology, implants come in a wide variety of sizes and shape to match the teeth that are missing. The surfaces of today’s dental implants give them a more natural look and feel. In addition, the surface of the dental implant also attaches to the bone much easier and for a longer period of time.

Dr. Branemark's discovery has left an impression on dental professionals, all over the world, including Dr. Ghenta. If you are considering dental implants to improve your smile’s health, beauty, and function, be sure to contact our Dartmouth, MA office to schedule an appointment.

Happily for all of us who like to celebrate with friends and family, there’s no need to be Irish to enjoy St. Patrick’s Day. Every March 17^th, many of us take the opportunity to display a bit of Gaelic spirit.

• Green Clothing (it’s tradition!)
• Green Hat (for a jaunty look)
• Green Shamrock (always the perfect accessory)
• Green Hair (for the adventurous among us)
• Green Grins?

Here’s where we draw the line. Emerald Isle? Delightful! Emerald smile? Not so beguiling.

That traditional St. Patrick’s party fare—green-frosted sweet treats and green-colored pastries and green-foamed beers—is full of green-tinted food dyes, which can leave us with teeth in subtle shamrock shades. Luckily, most of us will have only a very temporary tinge to remind us of our dietary shenanigans, and there are simple ways to rid yourself of the green sheen:

• Indulge sparingly in colorful cuisine, and drink water afterwards to rinse away green-dyed foods and beverages.
• Use a straw for green drinks.
• Brush your teeth. (Not only will you brush away the green, but you’ll brush away the sugars from sweet green desserts and the acids from sour green brews.)
• Try a whitening toothpaste.

One special note: if you’ve just whitened your smile, best to eliminate strong food dyes from your diet for a few days. Teeth are more sensitive to staining after whitening, because the whitening process temporarily makes them more porous. Give yourself a few days, and your enamel will be back to (stain)fighting strength.

So, celebrate on the 17^th and feel secure that on the 18^th, your smile won’t be “wearing the green” any longer. But if you find that you’re not happy with the appearance of your smile anytime during the year, if you have more permanent staining caused by natural darkening over time, or workdays fueled by black coffee, or a diet filled with tomato sauce, dark berries, red wine, and other tasty (but discoloring) food, you’re still in luck.

Ask Dr. Ghenta about professional whitening procedures at our Dartmouth, MA office for a brighter, more confident smile. And with a bright, confident smile, every day’s a reason to celebrate!
