Have you heard about dental sealants? These preventive treatments have been available for many decades, and more and more children are taking advantage of them. The National Institutes of Health (NIH) estimates that around 30% of kids from 6 to 11 years of age have had sealants applied to their molars (back teeth). Sealants are designed to reduce the incidence of cavities by filling in or eliminating the pits or crevices found in all molars, where decay-causing bacteria can hide and your brush can't reach. But do they really work?
Now, the research is in, and the answer is clear — YES!
Two major studies, each of which reviewed the results of thousands of patients over several years, recently came to the same conclusion: Dental sealants are effective at reducing cavities, and their benefits can last for four years (or more) after application. In general, the studies showed that kids who didn't get sealants were twice, three times, or even more likely to get cavities, compared to kids treated with sealants.
Sealants themselves are protective coatings made of plastic resins or glass-like materials. They are applied in liquid form, and then hardened by a special light. When “painted on” to the chewing surface of a molar, sealants fill in the tiny crevices, or “pits and fissures,” that are found there. Uneven tooth surfaces form a perfect breeding ground for the bacteria that cause tooth decay; worse yet, the bristles of a tooth brush can't usually reach them. That's what makes these areas highly susceptible to tooth decay.
Applying sealants is a quick and painless procedure that doesn't require any numbing shots or drilling. Many kids start getting sealants when the first permanent molars come in, around age 5 to 7; they may have more sealant treatments when additional molars emerge, between the ages of 11 and 14.
Sealants are recommended by the American Dental Association and the American Academy of Pediatric Dentistry, and have only a modest cost per tooth. On the other hand, having a cavity filled generally costs substantially more, and may result in more trouble (and expense) down the line — so sealants can make sense economically, as well as preventively. This is especially true for those at high risk for tooth decay.

While they're resilient, your child's teeth aren't invincible. Daily hygiene and regular dental visits are important, but you should also be alert for problems and take action when they arise.
Here are 4 areas that could cause problems for your child's teeth, and what you should do — or not do — if you encounter them.
Teething. This is a normal experience as your child's first teeth erupt through the gums. The gums become tender and painful, causing constant gnawing, drooling, disturbed sleep and similar symptoms. You can help relieve discomfort by letting them bite on a chilled (not frozen) teething ring or a cold, wet washcloth. Pain relievers like ibuprofen in appropriate dosages can also help — but don't apply ice, alcohol or numbing agents containing Benzocaine directly to the gums.
Toothache. Tooth pain could be a sign of decay, so you should see us for an examination. In the meantime you can help relieve pain with a warm-water rinse, a cold compress to the outside of the face, or appropriately-dosed pain relievers. If the pain is intense or persists overnight, see us no later than the next day if possible.
Swollen or bleeding gums. If you notice your child's gums are red and swollen or easily bleed during brushing, they could have periodontal (gum) disease. This is an infection caused by bacterial plaque, a thin film of food particles that build up on the teeth. You can stop plaque buildup by helping them practice effective, daily brushing and flossing. If they're showing symptoms, though, see us for an exam. In the meantime, be sure they continue to gently brush their teeth, even if their gums are irritated.
Chipped, cracked or knocked out tooth. If your child's teeth are injured, you should see us immediately. If part of the tooth has broken off, try to retrieve the broken pieces and bring them with you. If it's a permanent tooth that was knocked out, pick it up by the crown (not the root), rinse it with clean water and attempt to place it back in the socket. If you can't, bring the tooth with you in a container with clean water or milk. The sooner you see us, the better the chances for saving the tooth — minutes count.
It’s important that decay is detected and treated right away to prevent complications.
Tooth decay, the cause of cavities, is one of the most common dental disorders around, and it affects people of all ages, from children to senior citizens; fortunately, tooth decay is preventable with the proper oral care. From our office in Amherst, NH, pediatric dentists Dr. James McAveeney and Dr. Andrew Cheifetz are experts in treating dental decay—read below to learn about the warning signs of decay and how to prevent it from happening to your child.
How do I know that my child has tooth decay?
Decay can present differently for each child; however, there are some pretty reliable signs and symptoms that indicate your child should be checked out by the dentists at our Amherst office. One sign is a white spot or spots on a tooth. This is usually the beginning stage of decay.
As the decay progresses, the white spot will turn brown, and it will continue to get darker until a hole develops. Along with this warning sign, your child may also complain of tooth sensitivity, particularly to hot or cold foods and drinks, as well as general dental pain. If your child is experiencing any of these issues, you should schedule an immediate appointment with us.
Who is at risk for developing tooth decay?
Anyone can develop tooth decay since we all have bacteria in our mouths that can cause cavities. Of course, there are certain risk factors that can increase your child’s likelihood of developing decay. These risk factors include,
- A diet that is high in sugar and starches
- No fluoride treatment
- Poor oral hygiene
- Dry mouth
All children, no matter their risk factors, should come in every six months for routine checkups. This is the best way for us to detect problems early on. After all, a child may have a cavity and not even know it. Since warning signs aren’t always present it’s important for the health of your child’s smile to visit your pediatric dentist twice a year.
If you suspect that your child might be dealing with tooth decay it’s better to play it safe and to schedule a consultation with our dental team here at Children's Dental Center of New Hampshire. Call our Amherst office today at 603-673-1000!
At no other time in a person’s life will their teeth and mouth change as rapidly as it will between infancy and adolescence. In this short span an entire set of teeth will emerge and then gradually disappear as a second permanent set takes its place.
While the process may seem chaotic, there is a natural order to it. Knowing what to expect will help ease any undue concerns you may have about your child's experience.
The first primary teeth begin to appear (erupt) in sequence depending on their type. The first are usually the lower central incisors in the very front that erupt around 6-10 months, followed then by the rest of the incisors, first molars and canines (the “eye” teeth). The last to erupt are the primary second molars in the very back of the mouth just before age 3. A similar sequence occurs when they’re lost — the central incisors loosen and fall out around 6-7 years; the second molars are the last to go at 10-12 years.
A little “chaos” is normal — but only a little. Because of the tremendous changes in the mouth, primary teeth may appear to be going in every direction with noticeable spaces between front teeth. While this is usually not a great concern, it’s still possible future malocclusions (bad bites) may be developing. To monitor this effectively you should begin regular checkups around the child’s first birthday — our trained professional eye can determine if an issue has arisen that should be treated.
Protecting primary teeth from tooth decay is another high priority. There’s a temptation to discount the damage decay may do to these teeth because “they’re going to be lost anyway.” But besides their functional role, primary teeth also help guide the developing permanent teeth to erupt in the right position. Losing a primary tooth prematurely might then cause the permanent one to come in misaligned. Preventing tooth decay with daily oral hygiene and regular office visits and cleanings (with possible sealant protection) is a priority. And should decay occur, it’s equally important to preserve the tooth for as long as possible for the sake of the succeeding tooth.
Your child’s rapid dental development is part of their journey into adulthood. Keeping a watchful eye on the process and practicing good dental care will ensure this part of the journey is uneventful.
If you would like more information on the process of dental development in children, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Dentistry & Oral Health for Children.”
Is a chipped tooth big news? It is if you’re Justin Bieber. When the pop singer recently posted a picture from the dental office to his instagram account, it got over 2.6 million “likes.” The snapshot shows him reclining in the chair, making peace signs with his hands as he opens wide; meanwhile, his dentist is busy working on his smile. The caption reads: “I chipped my tooth.”
Bieber may have a few more social media followers than the average person, but his dental problem is not unique. Sports injuries, mishaps at home, playground accidents and auto collisions are among the more common causes of dental trauma.
Some dental problems need to be treated as soon as possible, while others can wait a few days. Do you know which is which? Here are some basic guidelines:
A tooth that’s knocked out needs attention right away. First, try and locate the missing tooth and gently clean it with water — but avoid holding the tooth’s roots. Next, grasp the crown of the tooth and place it back in the socket facing the correct way. If that isn’t possible, place it between the cheek and gum, in a plastic bag with the patient’s saliva or a special tooth preservative, or in a glass of cold milk. Then rush to the dental office or emergency room right away. For the best chance of saving the tooth, it should be treated within five minutes.
If a tooth is loosened or displaced (pushed sideways, deeper into or out of its socket), it’s best to seek dental treatment within 6 hours. A complete examination will be needed to find out exactly what’s wrong and how best to treat it. Loosened or displaced teeth may be splinted to give them stability while they heal. In some situations, a root canal may be necessary to save the tooth.
Broken or fractured (cracked) teeth should receive treatment within 12 hours. If the injury extends into the tooth’s inner pulp tissue, root canal treatment will be needed. Depending on the severity of the injury, the tooth may need a crown (cap) to restore its function and appearance. If pieces of the tooth have been recovered, bring them with you to the office.
Chipped teeth are among the most common dental injuries, and can generally be restored successfully. Minor chips or rough edges can be polished off with a dental instrument. Teeth with slightly larger chips can often be restored via cosmetic bonding with tooth-colored resins. When more of the tooth structure is missing, the best solution may be porcelain veneers or crowns. These procedures can generally be accomplished at a scheduled office visit. However, if the tooth is painful, sensitive to heat or cold or producing other symptoms, don’t wait for an appointment — seek help right away.
Justin Bieber earned lots of “likes” by sharing a picture from the dental office. But maybe the take-home from his post is this: If you have a dental injury, be sure to get treatment when it’s needed. The ability to restore a damaged smile is one of the best things about modern dentistry.
If you have questions about dental injury, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Repairing Chipped Teeth” and “Porcelain Crowns & Veneers.”
