Quick trivia question: define “mamelon.” Some kind of warm blooded animal? No, not a member of the mammal clan, but good guess. A fruit of the gourd family? Nope! There are watermelons, and honeydew melons, and even canary melons, but no ma-melons. Those little rounded bumps you notice on the edge of your child’s permanent incisors when they first emerge? We have a winning answer!

• Why Do We Have Mamelons?

We have eight incisors, or biting teeth, in the front of our mouths—four on top and four on bottom. Mamelons are actually a clue as to how these incisors were formed. Even before a baby is born, the permanent teeth begin to take shape. Three different groups of cells develop to form the incisal edge of these front teeth. As they fuse together, they create three lobes of enamel on the erupting edge of the tooth. It’s these lobes, or bumps, that give the teeth a serrated appearance.

Whether your child’s mamelons are quite prominent or barely noticeable, if you are worried about them, relax! They are almost always a temporary part of your child’s smile, and disappear over time with chewing and normal wear. But what if the mamelons overstay their welcome?

• Cosmetic Concerns

Because mamelons are composed of enamel, without the underlying dentin layer found in the body of the tooth, they can appear translucent or a bit different in color. They might wear away unevenly, leaving the tooth edges looking misaligned. Or, they might not wear away at all if your child’s tooth eruption is delayed. Talk to Dr. Ghenta if mamelons are a cosmetic concern for you or your child. You might discover that they are wearing away naturally, or we can discuss ways to polish or smooth them down if needed. This is a painless procedure that doesn’t require an anesthetic. Generally, however, this is a matter where time will resolve the issue for you.

• Orthodontic Implications

Occasionally, mamelons might become a topic of discussion for orthodontic reasons. Sometimes, mamelons do not wear away over time because of a malocclusion (misaligned bite). Your orthodontist will let you know your child has a bite problem and can explain treatment options. Your orthodontist might also suggest smoothing away the mamelons to ensure that the edges of the incisors align correctly and symmetrically while the teeth are in the process of straightening. Again, this is not always considered a necessity, so weigh your options with your dental care provider.

So, if you notice that your child’s beautiful new teeth are bumpy or serrated as they erupt, don’t be concerned! If you have any questions about mamelons, talk to Dr. Ghenta at your next visit to our Dartmouth, MA office. This is a natural occurrence and most likely just a temporary “bump” in the road. Soon enough, mamelons will be a memory—and the answer to a pretty difficult trivia question.

Our gums cover and protect the sensitive roots of our teeth and the bone around them. While we often think of gum tissue as a rosy shade of pink, that’s not a hard and fast rule. Just as skin tones vary, gum color can vary from person to person.

Healthy gums can range from light pink to darker pink to hues of brown or black. Because your gums are a good indicator of your oral health, what’s important isn’t your normal gum color, it’s noticing any changes in your normal gum color. These changes could be symptomatic of several different dental and medical conditions.

Pale Gums

• Anemia

If the overall appearance of your gums is paler than usual, anemia is a prime suspect. Anemia is a common condition caused by a low red blood cell count. Hemoglobin in red blood cells delivers the oxygen our tissues need to function properly, and without enough, we suffer symptoms like fatigue, weakness, pallor, faintness, and rapid heartbeat.

Anemia can be caused by an underlying medical condition, or can develop because of other issues, such as iron or vitamin deficiencies, pregnancy, ulcers, certain medications, or heavy menstrual periods. If you have any of the symptoms of anemia, seeing your doctor for a blood test is a good idea.

• Teeth Whitening

Occasionally, gums can also lighten up after a tooth whitening procedure. This is due to tissue irritation caused by the bleaching chemicals. Usually this condition is very temporary.

Ask Dr. Ghenta for advice if you experience irritation after home treatments. Having your teeth whitened by a dental professional is one way to make sure your gums get the best protection possible during the process.

Red Gums

• Inflammation

Red gums are a common symptom of gingivitis (early gum disease). Plaque and tartar irritate your gums, and gum tissue reacts to this irritation by becoming inflamed. Left untreated, gingivitis becomes periodontitis (serious gum disease), which can destroy the bone around the tooth and lead to tooth loss.

If you notice signs of gingivitis—redness, swelling, bleeding, bad breath—talk to Dr. Ghenta. Often, gingivitis is easily remedied in the early stages by better attention to dental hygiene. Brushing for two minutes at least twice each day and flossing at least once a day are a good base line for keeping gum disease at bay.

• Infection

Redness can also be caused by infection. If you’re experiencing redness, pain, loose teeth, swelling, pus, or fever, it’s important to see Dr. Ghenta as soon as possible in case you have an abscess or infected dental cyst. Without treatment, infection can seriously damage gum tissue, teeth, and underlying bone.

• Over-Vigorous Brushing

Brushing too hard or using the wrong brush can cause gum irritation. Do your gums (and teeth!) a favor by using proper brushing technique—massage, don’t scrub—and always use a soft-bristled brush.

Spots of Discoloration

Sometimes you notice a patch of lighter or darker tissue that you haven’t seen before. A spot that is different from the gum tissue around it can be harmless or need further attention.

Contact our Dartmouth, MA office if you have any recent discoloration, sores, pain, lumps, or any differences in appearance or sensation in your mouth. There are several types of oral cancer and prompt diagnosis and treatment is important to prevent the spread of cancerous cells.

You know your smile better than anyone. Any time you see a change in the usual appearance of your gums, it’s important to see Dr. Ghenta. Treating gum problems before they become serious is one of the best ways to keep yourself—and your smile—in the pink of health!

Gingivitis, or inflammation of the gums, is an early stage of gum disease. If you have gingivitis, it’s important to visit Dr. Ghenta to get proper treatment, since home care isn’t enough to get rid of the plaque that leads to tartar and eventually to gum disease. Monitor yourself to see if you have these signs of gingivitis, and get help as soon as you can to prevent the progression to periodontitis. Your vigilance could save your teeth.

1. You have one or more risk factors.

Having risk factors for gingivitis doesn’t mean that you have or will get the disease, but it does mean that you should be especially watchful. You’re more likely to get gum disease if you have the following risk factors:

• You are a smoker.
• You are a female going through puberty, pregnancy, or menopause.
• You have diabetes.
• You have a compromised immune system, as is the case if you have HIV/AIDS.
• You have a family history of gum disease.

2. You have inflammation in your gums.

Gingivitis is inflammation of the gums, and that is a tell-tale sign of the condition. Gingivitis or periodontitis can involve a bacterial infection, and inflammation is your body’s response to an injury or infection. The four standard signs of inflammation are pain, redness, swelling, and a higher temperature than normal.

If you have inflammation around your teeth, your gum disease may have progressed to the more serious condition of periodontitis. Dr. Ghenta can evaluate your case using a scope, or small ruler. The ruler is used to measure the pockets around your teeth, with a depth of one to three millimeters being normal.

3. Your teeth seem to be moving around.

Loose teeth are a classic sign of periodontitis. You may also have them if you have gingivitis. They can occur when your gum line recedes, or as the result of having soft bone in your jaw.

You might also notice other signs of your teeth moving around. For example, they may seem to be oddly spaced, or they could be separating from each other. You might also notice that your partial dentures don’t fit properly anymore, even if they’re not that old.

Gingivitis is a very treatable condition, but you need the help of Dr. Ghenta to keep it in check. Contact our Dartmouth, MA office to schedule an exam today!

From the time you were small, you’ve been warned about the dangers of plaque. Why? Because:

• It’s an unappealing film that sticks to your teeth
• It causes cavities
• It causes gum disease

And really, do we need to know much more than this to motivate us to brush? But if you’re in a curious mood, you might be wondering just how this soft, fuzzy film accomplishes all that damage. Let’s take a closer look at the sticky problem of plaque.

How does plaque form?

We live with hundreds of species of oral bacteria, most of which are harmless, and some of which are actually beneficial. But when our oral ecosystem gets out of balance, problems can occur. For example, without regular and thorough brushing and flossing, we start to build up plaque.

Plaque starts forming within hours of your last brushing. And even though plaque fits the very definition of “seems to appear overnight,” this biofilm is actually a complex microbial community with several different stages of development.

• It starts with saliva.

Saliva is vital to our oral health, because it keeps us hydrated, washes away food particles, neutralizes acids in the mouth, and provides minerals which keep our enamel strong. Saliva also contains proteins, which help form a healthy, protective film on the tooth surface. This film is called a pellicle.

• Bacteria attach to the pellicle.

There are species of oral bacteria that are able to attach themselves to the pellicle film within hours of its formation. As they become more firmly attached, they begin to grow and divide to form colonies, and are known as the early colonizers of the plaque biofilm.

• A complex biofilm forms.

If you’ve skipped brushing for a few days (please don’t!), you’ll notice a fuzzy, sometimes discolored film on your enamel—that’s a thriving plaque community, and it only takes a matter of days to go from invisible to unpleasant.

If you’re not removing plaque regularly, it can harden further and become tartar. And once you have tartar buildup, you’ll need the care of a dental professional to remove it.

• What happens if we ignore plaque and tartar?

We get cavities and gum disease.

How does plaque cause cavities?

• The bacteria in plaque, like all organisms, need nutrients.

Our normal oral environment and the food in our everyday diets provide the nutrients plaque needs. And, as we mentioned above, certain types of oral bacteria convert these nutrients into acids. Foods such as carbohydrates, starches, and sugars are most easily converted into acids, which is why we recommend that you enjoy them in moderation.

• The biofilm promotes acid production.

Within the plaque film, anaerobic bacteria (bacteria which don’t use oxygen) convert sugars and starches into acids. As the plaque film becomes denser, it blocks acid-neutralizing saliva and oxygen from reaching these bacteria close to the tooth’s surface, creating an ideal environment for the bacteria to produce their acid waste products.

• Acids attack enamel.

The sticky nature of plaque keeps these acids in contact with tooth enamel, where, over time, acids dissolve minerals in enamel, weakening the mineral structure of the tooth.

How does plaque cause gum disease?

• Bacteria cause inflammation and gingivitis.

The bacteria in plaque irritate the delicate tissue of the gums, which causes an inflammation response which can leave your gums swollen, red, bleeding, or tender. This early form of gum disease is gingivitis. Fortunately, good dental care and careful brushing and flossing can usually prevent and even eliminate gingivitis.

• Plaque and tartar can lead to periodontitis.

When plaque and tartar build up around and below the gumline, the gums pull away from the teeth, leaving pockets where bacteria collect, leading to infection as well as inflammation. Infections and constant inflammation not only harm gum tissue, they can destroy the bone supporting the teeth. This serious gum condition is periodontitis, and should be treated immediately to avoid further infection and even tooth loss.

How do we fight plaque?

From the time you were small, you’ve learned how to fight plaque:

• Brush at least twice a day for two minutes, and be sure to brush all of your tooth surfaces and around the gumline.
• Floss to remove plaque from between the teeth and near the gumline.
• Visit our Dartmouth, MA office for a thorough professional cleaning.

Be proactive. If you have any questions, talk to Dr. Ghenta about the best way to keep plaque at bay. We can show you the most effective ways to brush and floss, recommend anti-plaque toothpastes and rinses, even suggest plaque-revealing tablets if you’re missing some trouble spots.

We’ve only brushed up on some plaque basics, because there is a lot more to discover about this complex biofilm. Happily, even with all there is to learn about plaque’s growth and development, it’s reassuring to know that getting rid of it is quite simple—with just a soft-bristled brush, some dental floss, and a few minutes of your time each day, you’re on the way to a healthy, happy, plaque-free smile.
