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.

Root canal therapy is the unsung "hero" of dentistry. Although often falsely maligned as an unpleasant experience, millions of decayed teeth have been saved thanks to this routine treatment.
But although root canal therapy can save your tooth, we can't guarantee it won't be affected by another infection. There are other factors to consider how long a treated tooth will remain healthy.
Root canal therapy stops and limits the damage from tooth decay that has infected the inner pulp and root canals. A dentist or endodontist (a root canal specialist) drills into the tooth to gain access to the pulp. They remove the diseased pulp tissue and then fill the empty pulp chamber and root canals with a specialized filling called gutta percha. The tooth is then sealed and later crowned to protect it against future fracture or infection.
The probability of that occurring may depend on when a dentist performs the root canal in the disease progression—and the earlier the better. If decay has already infected the underlying bone, the tooth's long-term prognosis even with root canal therapy could be dim. That's why you should see a dentist as soon as possible for any tooth pain, even if it goes away.
The type of tooth could impact long-term health. Teeth with single roots are usually easier to treat. But those with multiple roots and an intricate root canal network can be more difficult to treat, and require specialized equipment and techniques.
Age can also impact root canal therapy longevity. The older a root canal-treated tooth is, the more brittle and susceptible to fracture it can become, which can pose complications. That's why we typically place crowns on treated teeth to protect them from both future infection and undue stress created while biting and chewing.
To help mitigate these possible factors, you should see your dentist regularly for checkups and at the first sign of pain or other abnormalities for the earliest treatment possible. And for more complex tooth issues, your dentist may refer you to an endodontist to perform your root canal. With early intervention and attentive care, your root canaled tooth could enjoy many years of life.

While braces are often the stars for straightening smiles, they're not the only cast members in an orthodontic production. Orthodontists occasionally turn to other appliances if the bite problem is challenging. Whatever the tool, though, they usually have something in common—they use the principle of anchorage.
To understand anchorage, let's first consider the classic kid's game Tug of War. With teams on either end of a rope, the object is to pull the opposing team across the center line before they pull you. To maximize your pulling force, the player at the back of your rope, usually your stoutest member, holds steady or "anchors" the rest of the team.
Like a Tug of War team, braces exert force against the teeth. This stimulates the supporting periodontal ligament to remodel itself and allow the teeth to move. The braces use the teeth they are attached to as anchors, which in a lot of cases are the back teeth. By attaching a thin wire to the brackets or braces on the teeth, the orthodontist includes all the teeth on the arch, from one end to the other. Anchored in place, the wire can maintain a constant pressure against the teeth to move them.
But not all bite situations are this straightforward. Sometimes an orthodontist needs to influence jaw growth in addition to teeth movement. For this purpose, they often use orthodontic headgear, which runs around the back of the head or neck and attaches to orthodontic brackets on the teeth. It still involves an anchor but in this case it's the patient's own skull.
In some situations, an orthodontist may feel he or she needs more anchorage as the teeth alone may not be enough. For this, they might establish a separate or additional anchor point using a temporary anchorage device (TAD). A TAD resembles a tiny screw that's inserted into the jawbone near the tooth intended for movement. The orthodontist can then attach the TAD to braces hardware using some form of elastics. After treatment, they remove the TAD.
These are just a couple examples of specialized tools an orthodontist can use for bite correction. Thanks to them and similar devices, even the most complex bite problem can be overcome to create a healthier and more attractive smile.
