We’re used to seeing athletes wearing mouthguards at practice or play, because dental trauma is one of the most common (and predictable) sports injuries. But it’s not just athletes who are at risk, and there are some events in our daily lives that we just can’t predict. Car accidents, falls, workplace injuries, even innocent playground structures can take their toll on our smiles.

A major chip or a crack in your tooth is upsetting enough, and should be seen by Dr. James Robson as soon as possible. It’s even more unnerving when a tooth is knocked out completely. The technical term for a tooth which has been knocked out is an avulsed tooth, and it is a true dental emergency.

If you should suffer a partially or completely dislodged tooth, there is a possibility that your tooth can be reimplanted—if the damage isn’t too severe and if you get to our office immediately.

How can a lost tooth be saved? This is possible because of the complex biological engineering that anchors our teeth within the jaw. The root of a tooth is surrounded by the periodontal ligament. This connective tissue attaches the tooth to the alveolar bone of the jaw. When a tooth is knocked out, this ligament splits apart, leaving some tissue on the tooth root and some within the tooth’s socket.

To successfully reimplant a tooth, the connective tissue cells around the root of the tooth need to be vital, so that they can begin to reattach to the connective tissue left in the socket. Over time, this reattachment is complete, and the tooth becomes firmly anchored to the bone again.

It’s important to protect your tooth before you see Dr. James Robson to make sure there will be enough healthy tissue for reattachment. First of all,

• Don’t panic! If you or a friend or family member lose a tooth, call your dentist or your emergency health care provider as soon as possible. You will get specific instructions for your specific situation.

If you are unable to reach a healthcare provider immediately, there are some general rules for taking care of an avulsed tooth:

• Find the lost tooth. Don’t touch the root—use the crown, or top part of the tooth, to pick it up. You are trying to preserve and protect the connective tissue on the root surface.

• If the tooth is dirty, gently rinse it in milk, saliva, or water. Don’t wipe it off, though. You could damage those connective tissue cells mentioned above.

• Place the tooth back in the socket, if possible. Gently hold it in place with your fingers or bite down (again, gently). You can also place the tooth in your mouth next to your cheek.

• If returning the tooth to the socket is not an option, or if you are worried about a child possibly swallowing the tooth, keep the tooth moist. Whole milk or solutions sold just for the purpose of preserving an avulsed tooth are better choices than water, which damage the tissue cells on the root. And never wrap the tooth tightly—this can also damage the connective tissue.

Above all,

• Don’t delay! The faster a tooth is reimplanted in its socket, the greater chance you have of keeping it. Really, every minute counts. Reimplantations are more successful if they take place within 30 minutes. After an hour out of the mouth, your tooth’s chances of successful reintegration are lower—but still worth pursuing!

What will Dr. James Robson do?

• Evaluate the avulsed tooth.

There are variables which can affect whether or not a lost tooth is a good candidate for reimplantation. Trying to replace a baby tooth, for example, could interfere with the formation of the adult tooth. An adult tooth that is broken will probably require a different type of treatment.

• Prevent infection.

You might be given antibiotics and a referral to your medical doctor for a tetanus booster if needed.

• Clean the site.

The socket will be gently irrigated to clean the area and to remove any clots that may have formed which can interfere with the tooth’s placement.

• Recommend or perform a root canal.

Nerves and blood vessels within the tooth’s pulp generally don’t recover after a serious traumatic injury, so a root canal procedure could be necessary to preserve the health of your tooth. This procedure might be done immediately, or might be recommended for a later date.

• Stabilize your tooth.

The tooth must be stabilized after being reimplanted, so Dr. James Robson will use a splint to anchor the tooth to the teeth next to it. The splint can be flexible or rigid, depending on the condition of the alveolar bone. Splinting generally takes from two to eight weeks, and you will be given detailed instructions for taking care of the area while you heal.

Losing a tooth is an alarming experience. But with prompt action, and a trip to our East Lyme, CT office, it might be possible to make that loss only a temporary one.

Probably because, for many kids, molars do get more cavities. So let’s answer two better questions: Why do molars get more cavities? And, how can we help prevent them?

It’s the Pits. (And Fissures.)

The reason molars are so useful—and more likely to develop cavities—is because of their shape. Unlike our front teeth, which are used to bite through foods, molars are used to grind and chew. That’s why they are so much larger, with a flat surface on top. Well, not exactly flat.

When you look at a molar, you’ll notice that the top isn’t really smooth at all. It’s covered with little indentations known as pits and longer grooves called fissures. These irregular features both trap food particles and make it more difficult for bristles to clean them away. Cavities in molar surfaces are so common that they even have a specific name: “pit and fissure cavities.”

But molar biology does not mean tooth decay is inevitable! There are steps you can take to protect your children’s molars as they grow, while you’re providing them with dental strategies that will keep their adult molars healthy and cavity-free.

Preventing Pit and Fissure Cavities

• Don’t Just Brush—Brush Effectively

The first step in preventing any kind of cavity is brushing properly. Your child should be brushing at least two minutes, at least twice each day. And while the time we spend brushing is important, technique is also key.

When you’re showing your child how to brush, be sure that the tops of molars, upper and lower, get brushed thoroughly, with special emphasis on cleaning pits and fissures. Make sure the toothbrush is small enough to fit your child’s mouth comfortably and reach all the tooth surfaces. Replace worn-down brushes or electric toothbrush heads after three to four months when they no longer clean as effectively.

Your child will probably need adult supervision from toddler years through the early years of grade school to learn how to brush properly. This is time well spent, as your child learns cavity-preventing brushing techniques which will last a lifetime.

• Eat a Tooth-Healthy Diet

Plaque bacteria use the sugars in our food to make acids. These acids break down the mineral strength of tooth enamel and eventually lead to cavities. And because pits and fissures are great hiding places for bacteria and food particles (especially sticky ones), molars are even more at risk for cavities. Limiting sugary, sticky foods like sweet treats and simple carbs helps reduce that risk.

Acidic foods like flavored juices, sour candies, sodas, and power drinks also weaken enamel and can leave teeth more vulnerable to decay. Help your child avoid cavities by limiting acidic foods and drinks, making them part of a balanced meal, and/or rinsing with water after eating.

• Use Fluoride Toothpaste

Fluoride toothpaste not only reduces the risk of cavities, it also helps strengthen enamel that has been weakened by bacterial and dietary acids. Win-win!

• Ask About Sealants

Sealants are invisible, safe coatings which protect molars by preventing food and bacteria from getting trapped in their uneven surfaces. The top of the molar is first treated with an etching solution to allow the sealant to bond tightly to the tooth, a thin coat of sealant is painted on, and then it’s hardened under a curing light. That’s all there is to it.

Sealants are often recommended when children’s permanent molars first erupt, when they are especially at risk for cavities. Sealants can last from three to five years (or even longer), and studies have shown a dramatic reduction in cavities for patients who use sealants compared to patients with untreated teeth. Depending on your child’s individual needs, Dr. James Robson might recommend a sealant for baby molars as well.

• Regular Exams and Cleanings

It might be hard for you to tell if your child’s molars have been affected by sticky plaque, or sugary foods, or acidic drinks, or inadequate brushing, or any other potential cavity-causers. It’s not a difficult job for Dr. James Robson, though! Through regular checkups and cleanings at our East Lyme, CT office, we will discover any conditions that might lead to cavities, and, if necessary, treat small cavities before they lead to more serious decay.

Statistically, childhood molars have a greater chance of developing cavities than incisors and canines. Help your child beat the odds by understanding why these teeth are at risk and by working with your dental team to give your child years of healthy teeth now and a future filled with beautiful smiles!

When patients of Robson Dentistry hear any mention of oral or dental hygiene, they probably think of brushing and flossing their teeth. Although these are extremely important, the term dental hygiene encompasses much more than that. Your mouth’s health, including your teeth, has an important impact on your overall physical health. The National Institute of Dental and Craniofacial Research published the surgeon general's first ever report on dental health. It is called A National Call to Action to Promote Oral Health. In that report, the Surgeon General states that the 1948 World Health Organization expanded its earlier definition of health to "a complete state of physical, mental, and social well-being, and not just the absence of infirmity."

The Importance of Oral Health to Total Overall Health

One of the most important themes that the dental health report stressed is that you cannot be healthy without oral health. It went on to explain that oral health and general health are inextricably linked, and therefore can't be seen as two separate things. Because oral health is so critical to overall health, it should be included in all community health programs. For individuals, this means that it is just as important to take care of your mouth, your teeth, and your overall oral health as it is to take care of the rest of your body. The two most prevalent dental diseases are caries (cavities), also known as tooth decay, and periodontal (gum) disease.

Ways that Oral Health Impacts Overall Health

One important way in which good oral health contributes to better overall health is seen in the findings of several studies in which the blood sugar levels of diabetic patients were significantly lowered when their periodontal (or gum disease) was successfully treated. Your mouth has roughly 500 different species of bacteria. Many are harmless, and some are even good bacteria that help maintain the balance of your intestinal flora. Harmful bacteria can infect your gums, causing gingivitis. Your body's immune system may try to fight off the alien invaders, but they attack your gums, causing inflammation and bleeding when you brush.

Now that you know how important good dental hygiene is, be sure to see to get your teeth cleaned every six months, have regular dental checkups, brush and floss your teeth at least twice daily, and replace your toothbrush at least every couple of months. Call us to schedule your next appointment at our convenient East Lyme, CT location.

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. James Robson. 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 East Lyme, CT 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. James Robson 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. James Robson 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 East Lyme, CT office. After all, even though they go unnoticed, strong roots are the foundation of a healthy, attractive, life-long smile.
