Dental sealants are an excellent way to protect children’s teeth from tooth decay by coating them with a thin plastic material. Their teeth look and feel like normal, but they are protected from plaque build-up and decay early on. Dr. Melissa Dennison Newman and our staff recommend sealants as a preventive measure for children before any decay appears on their teeth.

Who should get dental sealants?

Dental sealants are intended for young children as soon as their first teeth come in. Decay is most common in the molars, so taking your child to Highland Family Dental for sealants right when you see the molars grow in gives your child the best chance to fight tooth decay.

A child’s first set of permanent molars grow in between ages five and seven, while the second permanent molars come in between 11 and 14 years of age. Some teens and adults who don’t have tooth decay may get sealants as well, but it is less common.

How long do dental sealants last?

Once the sealant has been placed on the teeth, it lasts up to ten years. Expect to have Dr. Melissa Dennison Newman check the sealant at every visit to our Plaistow, New Hampshire office, which should be twice a year. We will look at the sealant and determine if it needs to be replaced.

What is the process of getting sealants?

Applying sealants is a simple, pain-free procedure that is done quickly at Highland Family Dental. There is absolutely no effect on the tooth structure from sealants.

For starters, the teeth are cleaned carefully, then dried with an absorbent material. A mild acid solution is applied to them to roughen them slightly. This is done so the sealant can bond properly to the teeth. Then the teeth are rinsed and dried, and the sealant material is painted on and dried with a special light.

Molars are susceptible to decay early on, which is why sealants are an important treatment to get for your children’s first set of teeth.

The wisdom teeth are the last of the permanent molars to emerge from the gums. This can occur as early as age 17 or as late as 21. Though some teens and young adults experience a completely normal tooth eruption with ideally aligned molars that pose no health threat, this is not the case for everyone.

According to the American Association of Oral and Maxillofacial Surgeons (AAOMS), wisdom teeth must meet specific criteria to avoid a required extraction. These guidelines include:

• Completely erupted and non-impacted
• Completely functional
• Painless
• Free of decay
• Disease-free
• Capable of being properly cleaned

If one or more of your child’s wisdom teeth do not meet these conditions, we recommend scheduling an appointment with Dr. Melissa Dennison Newman; an extraction may be necessary.

Impacted wisdom teeth

One of the most common reasons for extracting a wisdom tooth is due to impaction. An impacted wisdom tooth is one that has not erupted and will not fully erupt from the gums. Usually this occurs because there is not enough room for the tooth to emerge. Impaction can be painful and can also lead to infection if left untreated. According to the AAOMS, roughly 90 percent of the teen and adult population has at least one impacted tooth. Extracting an impacted wisdom tooth early can help prevent future complications, such as periodontal disease, infections, and damage to neighboring teeth.

Extracting fully erupted wisdom teeth

Even if your child’s wisdom teeth are fully erupted, Dr. Melissa Dennison Newman and our team at Highland Family Dental may recommend removing them as a preventive measure. Fully-erupted third molars often interfere with a healthy bite. This can lead to problems with tooth and jaw alignment and may also contribute to the development of headaches. Your child’s wisdom teeth may also be more prone to tooth decay and gum disease, because their location in the back of the mouth makes them more difficult to reach for brushing and flossing.

It’s common for toddlers to be wary of strangers, but their first experience at the dentist shouldn’t be a scary one. Dr. Melissa Dennison Newman and our team have five tips for you to make your child’s first visit to Highland Family Dental easy as pie!

1. Bringing your child to one of your own appointments before his or her first dental visit can calm your little one’s nerves. This gives your son or daughter the opportunity to get familiar with our office and see a cleaning isn’t very scary.
2. Our big dental chair can be fun! Toddlers love games, and seeing the chair go up and down can make it seem like an amusement ride rather than sitting down for an exam.
3. Dr. Melissa Dennison Newman and our team hand out cool toothbrushes and stickers to kids after their appointment. Your child will love the fun-colored toothbrush and can look forward to a post-appointment prize at the next visit.
4. Schedule your appointment for a time that sets you up for success. Bringing your child to our Plaistow, New Hampshire office an hour before he or she is due for a nap may be a tantrum just waiting to happen.
5. Kids love books! Try reading your toddler bedtime stories about what happens at the dentist before you come in for the appointment. We recommend Dora the Explorer’s Show Me Your Smile, written by Christine Ricci.

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 Plaistow, New Hampshire office for a thorough professional cleaning.

Be proactive. If you have any questions, talk to Dr. Melissa Dennison Newman 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.
