Your child's permanent teeth come in gradually, starting just as they begin losing their primary ("baby") teeth and not ending until late adolescence or early adulthood. That's when the third molars or "wisdom teeth" close out the process.
Because of their late arrival, wisdom teeth have a high potential for dental problems. With a greater chance of crowding or obstruction by other teeth, wisdom teeth often get stuck fully or partially below the gums and bone (impaction) or erupt out of position. In one study, 7 in 10 people between the ages of 20 and 30 will have at least one impacted wisdom tooth at some time in their lives.
It's not surprising then that wisdom teeth are among the most extracted teeth, to the tune of about 10 million per year. Besides those already diseased or causing bite problems, many are removed preemptively in an attempt to avoid future problems.
But wisdom teeth usually require surgical extraction by an oral surgeon, which is much more involved than a simple extraction by a general dentist. Given the potential consequences of surgical extraction, is it really necessary to remove a wisdom tooth not creating immediate problems?
That's not an easy question to answer because it's often difficult to predict a wisdom tooth's developmental track. Early on it can be disease-free and not causing any problems to other teeth. But as some researchers have found, one in three wisdom teeth at this stage will later develop disease or create other issues.
For many dentists, the best approach is to consider extraction on a case by case basis. Those displaying definite signs of problems are prime for removal. But where there are no signs of disease or other issues, the more prudent action may be to keep a watchful eye on their development and decide on extraction at some later date.
More than likely, your dentist will continue to have an ongoing discussion with you about the state of your child's wisdom teeth. While extraction is always an option, wisdom teeth that aren't yet a problem to dental health may be best left alone.
Cavities can happen even before a baby has his first piece of candy. This was the difficult lesson actor David Ramsey of the TV shows Arrow and Dexter learned when his son DJ’s teeth were first emerging.
“His first teeth came in weak,” Ramsey recalled in a recent interview. “They had brown spots on them and they were brittle.” Those brown spots, he said, quickly turned into cavities. How did this happen?
Ramsey said DJ’s dentist suspected it had to do with the child’s feedings — not what he was being fed but how. DJ was often nursed to sleep, “so there were pools of breast milk that he could go to sleep with in his mouth,” Ramsey explained.
While breastfeeding offers an infant many health benefits, problems can occur when the natural sugars in breast milk are left in contact with teeth for long periods. Sugar feeds decay-causing oral bacteria, and these bacteria in turn release tooth-eroding acids. The softer teeth of a young child are particularly vulnerable to these acids; the end result can be tooth decay.
This condition, technically known as “early child caries,” is referred to in laymen’s terms as “baby bottle tooth decay.” However, it can result from nighttime feedings by bottle or breast. The best way to prevent this problem is to avoid nursing babies to sleep at night once they reach the teething stage; a bottle-fed baby should not be allowed to fall asleep with anything but water in their bottle or “sippy cup.”
Here are some other basics of infant dental care that every parent should know:
- Wipe your baby’s newly emerging teeth with a clean, moist washcloth after feedings.
- Brush teeth that have completely grown in with a soft-bristled, child-size toothbrush and a smear of fluoride toothpaste no bigger than a grain of rice.
- Start regular dental checkups by the first birthday.
Fortunately, Ramsey reports that his son is doing very well after an extended period of professional dental treatments and parental vigilance.
“It took a number of months, but his teeth are much, much better,” he said. “Right now we’re still helping him and we’re still really on top of the teeth situation.”

While wearing braces is the path to a healthier and more attractive smile, it can be a difficult journey. One of your biggest challenges will be keeping your teeth clean to avoid a higher risk of tooth decay.
Tooth decay starts with dental plaque, a thin film of bacteria and food particles that accumulates on teeth. Daily brushing and flossing clear this accumulation. But the hardware of braces makes it difficult to access all tooth surfaces, and can even become a haven for plaque.
One sign in particular of tooth decay while wearing braces is the appearance of chalk-like spots on the teeth known as white spot lesions (WSLs). WSLs occur because the minerals in the enamel beneath them have begun to break down in response to decay. The spots can eventually cause both structural and cosmetic problems for a tooth.
The best approach to WSLs is to prevent them from developing in the first place. You'll need to be extra vigilant with daily oral hygiene while wearing braces to reduce plaque buildup. To help with the increased difficulty you might consider using a special toothbrush designed to maneuver more closely around orthodontic hardware. You may also find using a water flosser to be a lot easier than flossing thread.
Preventing tooth decay and WSLs also includes what you eat or drink to reduce the effects of enamel de-mineralization. The bacteria that cause decay thrive on sugar, so limit your intake of sweetened foods and beverages. And to avoid excessive demineralization cut back on acidic foods as well.
If despite your best preventive efforts WSLs still form, we can take steps to minimize any damage. For one, we can give your enamel a boost with fluoride applications or other remineralization substances. We can also inject a tooth-colored resin beneath the surface of a WSL that will make it less noticeable.
With any of these and other treatments, though, the sooner we can treat the WSL the better the outcome. Practicing good hygiene and dietary habits, as well as keeping an eye out for any WSL formations, will do the most to protect your new and improved smile.
