AStainlessSteelCrownCouldExtendtheLifeofaPrimaryMolar

One of the key elements in a child’s development is their first set of teeth. Although primary (“baby”) teeth last only a few years, they’re critically important for enabling a child to eat solid foods, speak and smile.

But they also provide one more important benefit—they hold the space in the jaw reserved for the permanent teeth developing just under the gums until they erupt. But if a child loses a primary tooth prematurely because of disease or injury, other teeth may drift into the vacant space and crowd it out for the intended permanent tooth. It may then come in misaligned or remain stuck within the gums (impaction).

To avoid this, we try to treat and preserve a diseased primary tooth if at all practical. For a primary molar, one of the large teeth in the back of the mouth, this might include capping it with a stainless steel crown.

Why a metal crown? Primary molars normally don’t fall out until around ages 10-12, so it may be years for a younger child before their permanent molars erupt. All during that time these particular teeth will encounter heavier biting forces than teeth in the front.

A steel crown is often the best solution for a molar given their longer lifespans and encountered biting forces. The crown’s metal construction can stand up to these forces while still protecting the tooth from re-infection from decay. And because molars are typically outside of the “smile zone” occupied by more visible front teeth, the crown’s metal appearance isn’t usually an aesthetic issue.

Crowning a molar usually takes one visit, a dentist typically performing the procedure with local anesthesia and possibly a mild sedative like nitrous oxide gas (“laughing gas”). After removing any decayed structure from the tooth, the dentist will then fit a pre-formed crown over the remaining structure, sized and shaped to match the original tooth as close as possible.

A stainless steel crown is a cost-effective way to added needed years to a primary molar that could otherwise be lost prematurely. Preserving it may help a child avoid bite problems and expensive future treatments.

MargotRobbieKnowsAGreatSmileIsWorthProtecting

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.

“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”

Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.

Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.

A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.

Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.

So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

If you have questions about teeth grinding or orthodontic retainers, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Teeth Grinding” and “The Importance of Orthodontic Retainers.”

HowtoKeepYourTeethandGumsHealthyDuringPregnancy

While pregnancy is an exciting time for expectant mothers, it can pose extra health challenges. This is especially true regarding dental health.

Because of hormonal changes that naturally occur during pregnancy, your teeth and gums are at higher risk for dental disease. These changes can increase cravings for carbohydrates, particularly sugar. Increased sugar consumption feeds bacteria found in dental plaque, which is most responsible for tooth decay and periodontal (gum) disease.

Hormonal changes can also make your gums more susceptible to infection. Conditions may be favorable for a form of gum disease called pregnancy gingivitis, which can begin as an infection in the surface layers of the gums. But like other forms of gum disease, pregnancy gingivitis can advance below the gum line and lead to serious health consequences.

Because of this "pregnancy effect" on your teeth and gums, there are some things to which you should pay heed while you're expecting. First and foremost, keep up a daily regimen of brushing and flossing to remove accumulated dental plaque. You should also control your sugar intake to minimize bacterial growth that can cause disease.

It's also important for you to continue regular dental visits during your pregnancy. Your dentist will monitor your dental health and initiate treatment if you begin to show signs of disease. Besides professional cleanings, your dentist may also prescribe antibacterial mouthrinses to combat bacteria.

As far as dental procedures, essential treatments like fillings, root canals or extractions are usually considered safe to perform during pregnancy. But elective treatments of a cosmetic nature are best postponed until after your baby's delivery.

One last tip: because of the higher risk of tooth decay or gum disease, be on the lookout for any abnormal signs in your mouth. This includes spots on the teeth, tooth pain or swollen, reddened or bleeding gums. If you see any of these signs, see your dentist as soon as possible.

Your teeth and gums are indeed at risk for disease during pregnancy. But daily hygiene, regular dental care and attention to signs of disease can help keep that danger at bay.
