Primary (baby) teeth don't last long. But despite their short life span, they do a number of important things, like enabling a child to eat solid food. But perhaps their most important long-term function is “paving” the way for their permanent replacements.
If one is lost prematurely, though, the permanent tooth might not come in properly aligned. That's why if a primary tooth is in danger of loss due to decay or injury, we'll do our best to save it.
But that could get a little tricky if the infected or damaged part of the tooth is the innermost pulp. If it were an adult tooth, the best course might be a root canal treatment: access the pulp, clear out the diseased tissue, and then fill the space with a special filling. But with a primary tooth (or a young permanent tooth for that matter) that may not be advisable.
That's because the pulp plays a more important role in a child's tooth than an adult's. Its nerves and other tissues stimulate dentin growth; a full root canal could disrupt that growth and weaken the tooth in the long run.
With a child's tooth, we proceed carefully depending on how infected or damaged the pulp might be. If it's only slightly exposed or not at all, we try then to remove as much decayed tooth material outside the pulp as necessary, then apply antibacterial agents or dentin growth stimulators.
If we do have pulp exposure, we'll try to remove only as much of the affected pulp as necessary through a procedure called a pulpotomy. This technique will only be used if the remaining pulp looks healthy or restorable to health.
If not, we may need to perform a pulpectomy to remove the entire pulp. Most like a typical root canal, it's a last resort: without the pulp, dentin growth could be stunted and the tooth won't develop as healthy as it should.
Of course, the best approach is to prevent teeth from developing such problems in the first place. So, be sure to practice effective daily hygiene with your child and keep up regular dental visits beginning at age one.

While we often associate tooth decay with cavities forming in a tooth’s visible or biting surfaces, the occurrence of this all too common disease isn’t limited to those areas. Cavities can develop in any part of a tooth exposed to bacteria.
Gum recession, the shrinking back of the gums from the teeth, can cause such exposure in areas normally covered by the gums. Because these areas are usually more vulnerable to infection when exposed, cavities can develop at or right below the gum line. Because of their location it can be difficult to fill them or perform other treatments.
One way to make it less difficult is to perform a crown lengthening procedure. While the term sounds like we’re increasing the size of the tooth, we’re actually surgically altering the gums to access more of the affected tooth surface for treatment. It’s typically performed in a dental office with local anesthesia by a general dentist or a periodontist, a specialist in the gums.
During the procedure, the dentist starts by making small incisions in the gums to create a tissue “flap” that can be lifted out of the way. This exposes the underlying bone, which they then reshape to support the gum tissue once it’s re-situated in its new position. The dentist then sutures the gums back in place. Once the gums heal, the decayed area is ready for treatment.
Crown lengthening is also useful for other situations besides treating cavities. If a tooth has broken off at the gum line, for example, there may not be enough remaining structure to support a crown. Crown lengthening can make more of the underlying tooth available for the crown to “grab” onto. It’s also useful in some cases of “gummy smiles,” in which too much of the gum tissue is visible in proportion to the tooth size.
Because crown lengthening often involves removing some of the bone and is thus irreversible, you should discuss this procedure with your dentist in depth beforehand. It could be, though, this minor procedure might make it easier to preserve your teeth and even make them look more attractive.
Teeth lost to tooth decay can have devastating consequences for a child’s dental health. Not only can it disrupt their current nutrition, speech and social interaction, it can also skew their oral development for years to come.
Fortunately, we have a number of preventive tools to curb decay in young children. One of the most important of these, dental sealants, has been around for decades. We apply these resin or glass-like material coatings to the pits and crevices of teeth (especially molars) to help prevent the buildup of bacterial plaque in areas where bacteria tend to thrive.
Applying sealants is a simple and pain-free process. We first brush the coating in liquid form onto the teeth’s surface areas we wish to protect. We then use a special curing light to harden the sealant and create a durable seal.
So how effective are sealants in preventing tooth decay? Two studies in recent years reviewing dental care results from thousands of patients concluded sealants could effectively reduce cavities even four years after their application. Children who didn’t receive sealants had cavities at least three times the rate of those who did.
Sealant applications, of course, have some expense attached to them. However, it’s far less than the cost for cavity filling and other treatments for decay, not to mention future treatment costs resulting from previous decay. What’s more important, though, is the beneficial impact sealants can have a child’s dental health now and on into adulthood. That’s why sealants are recommended by both the American Dental Association and the American Academy of Pediatric Dentistry.
And while sealants are effective, they’re only one part of a comprehensive strategy to promote your child’s optimum dental health. Daily brushing and flossing, a “tooth-friendly” diet and regular dental cleanings and checkups are also necessary in helping to keep your child’s teeth healthy and free of tooth decay.
