Ask any kid and they'll tell you just how valuable "baby" teeth really are—out of the mouth, of course, and under their pillow awaiting a transaction with the Tooth Fairy. But there's more to them than their value on the Fairy Exchange Market—they play a critical role in future dental health.
Primary teeth provide the same kind of dental function as their future replacements. Children weaned from nursing can now eat solid food. They provide contact points for the tongue as a child learns to speak. And they play a role socially, as children with a "toothsome" smile begin to look more like what they will become when they're fully mature.
But primary teeth also serve as guides for the permanent teeth that will follow. As a future tooth develops below the gum line, the primary tooth preserves the space in which it will erupt. Otherwise, the space can be taken over by other teeth. This crowds out the intended tooth, which may erupt out of position or remain impacted below the gum line.
In either case, the situation could create a poor bite (malocclusion) that can be quite costly to correct. But if we can preserve a primary tooth on the verge of premature loss, we may be able to reduce the impact of a developing malocclusion or even prevent it.
We can help primary teeth last for their intended lifespan by preventing tooth decay with daily oral hygiene or clinically-applied sealants and topical fluoride. If they do become infected, it may be worth the effort to preserve them using procedures similar to a root canal treatment.
If a tooth can't be preserved, then we can try to reserve the empty space for the future tooth. One way is a space maintainer, which is a stiff wire loop attached to metal band bonded around an adjacent tooth. This keeps other teeth from drifting into the space until the permanent tooth is ready to erupt, at which time we can remove the appliance.
Your child may be anxious to get another tooth to put under their pillow. But helping that primary tooth go the distance will be more than worth it for their future dental health.

Although costly in the beginning, dental implants often turn out to be the least expensive tooth replacement option. That's because their enviable record for longevity often outpaces dentures or bridges. Over the long-term you might spend less for implants than these other restorations.
But even with the high success rate of dental implants (greater than 95% survive the ten-year mark), we can't guarantee they won't fail. And if you're a tobacco smoker, the risk of failure might be even higher. One study, for example, found early implant failures were twice the rate for smokers over non-smokers. Although implant failures overall are low, smoking seems to be a factor in those that do.
There are a number of reasons to account for this. For one thing, inhaled smoke can damage salivary glands, reducing the flow of this important fluid. Saliva helps control bacterial growth and neutralize mouth acid, so without it you're more susceptible to tooth decay or periodontal (gum) disease. Either infection could ultimately weaken implant-supporting bone.
The nicotine in tobacco can also restrict oral blood vessels and lower their ability to supply antibodies and nutrients to the teeth and gums. This slows healing, which could have one particular effect on implant durability.
During the intervening weeks between implant placement and crown attachment, the implant's titanium post attracts bone cells that grow and adhere to its surface. The effects of nicotine on healing, especially right after implant surgery, can interfere with this integration process so that the implant doesn't anchor in the bone as well as it should.
If you're a smoker, you can increase your chances of implant success—and have a healthier mouth overall—by quitting smoking beforehand with the help of a cessation program. Or at the least, consider stopping smoking for one week before implant surgery and for two weeks afterward.
And be sure to brush and floss your teeth daily and visit your dentist regularly to keep your teeth and gums as healthy as possible. Stopping smoking and practicing effective oral hygiene could make a big difference in the success or failure of your implant.

As Spring turns to Summer, millions of students will depart high school in the time-honored rite of passage called graduation. At the same time, quite a few of these graduates will be experiencing another maturity milestone: the eruption (coming in) of their last permanent teeth.
Typically, these are the back third molars, better known as “wisdom teeth,” emerging on either end of both the top and bottom jaws sometime between the ages of 18 and 24. Their arrival heralds the end of a long development process that began in infancy.
But this auspicious event can give rise to dental problems. Because they’re the last to come in, wisdom teeth often erupt in an environment crowded by earlier teeth. Depending on jaw size and other factors, there may not be enough room for a normal eruption.
Wisdom teeth can thus erupt out of position, creating a poor bite (malocclusion). Or they might not erupt at all—becoming stuck fully or partially within the gums and bone, a condition known as impaction. Impacted teeth can also cause problems for the adjacent teeth, damaging the roots of the second molars or disrupting the surrounding gum tissue, making them more susceptible to periodontal (gum) disease.
Because of these and other issues, impacted wisdom teeth are among the most common type of teeth removed: an estimated 10 million each year. And many of these are removed before they show signs of disease or complications as a preemptive strike against developing dental problems.
Although unnecessary surgery should always be avoided, according to some research, there’s a one in three chance that erupting wisdom teeth that are not showing signs of trouble will eventually become problematic. And the earlier they’re removed, the lower the risk of post-extraction complications.
Wisdom teeth should always be evaluated on a case by case basis. Those with obvious signs of disease or complications do require prompt treatment, including possible extraction. Others that are asymptomatic can be monitored over time: If they’re tending to become problematic, we can adjust the treatment plan accordingly. Our goal is to ensure these particular teeth signaling the end of childhood won’t detract from dental health in adulthood, so a measured approach seems to be the best and safest one.
