TheRightTreatmentforYourChildsInjuredToothIncreasesitsSurvival

Children have a lot of energy that's often channeled through physical activities and sports. Unfortunately, this also increases their risk of injuries, particularly to their teeth.

Injuries to the mouth can endanger permanent teeth's survival. For an older tooth, a root canal treatment might be in order. Not so, though, for a pre-adolescent tooth, even if it is permanent.

A young permanent tooth is still developing dentin, the large layer just below the enamel. This growth depends on the connective tissue, blood vessels and nerves within the pulp in the center of the tooth. Because a root canal treatment removes all of this tissue, it could stunt dentin and root growth and endanger the tooth's future.

Instead, we may need to treat it with one of a number of modified versions of a root canal, depending on what we find. If the tooth's pulp is unexposed, for example, we may need only to remove the damaged dentin, while still leaving a barrier of dentin to protect the pulp. We then apply an antibacterial agent to minimize infection and fill in the area where we've removed tooth structure.

If some of the pulp is exposed, we may perform a pulpotomy to remove just the affected pulp and any overgrown tissue. We then place a substance that encourages dentin growth and seal it in with a filling. If we go deeper toward the root end, we might also perform procedures that encourage the remaining pulp to form into a root end to stabilize the tooth.

If the entire pulp has been damaged beyond salvage, we may then turn to a procedure called an apexification. In this case we clean out the pulp chamber; at the root end we place mineral trioxide aggregate (MTA), a growth stimulator that encourages surrounding bone to heal and grow. We then fill in the root canals and chamber with a special filling called gutta percha to seal the tooth.

The deeper we must penetrate into the pulp, the higher the chances the young tooth's dentin and roots won't form properly, leading to later problems and possible loss. But by employing the appropriate one of these methods, we can minimize the risk and give your child's damaged tooth a fighting chance.

TheTypeofToothPainYouHaveCouldbeTellingYouWhatsWrong

As with the rest of the body, tooth pain is an indication that something’s wrong. While the exact cause requires a dental exam, the location, quality and duration of the pain could narrow the possibilities. With that in mind, here are 3 types of tooth pain and what it might be telling you.

Sensitivity. Pain or discomfort when you eat or drink cold foods or bite down could mean you have a small area of decay in the tooth, a loose filling or an exposed root surface from gum recession. Dental work to repair a decayed tooth or filling could alleviate the pain; in the case of gum recession, you may need to reduce overaggressive brushing or seek treatment for periodontal (gum) disease, the two main causes of the condition.

Dull or lingering pain. A dull ache in the rear sinus area could indicate a problem with a back tooth — they share the same nerve pathways as the sinuses, so you may be feeling referred pain. In the case of lingering pain after eating or drinking something hot or cold, there may be decay within the inner pulp chamber of the tooth that’s damaging or even killing the nerve tissue. If so, a root canal treatment might be in order.

Sharp pain. That sudden, excruciating pain when you bite down could mean you’re experiencing advanced decay, a loose filling or possibly a cracked tooth. If the pain seems to radiate from the gums — and they’re swollen and sensitive — you may have developed an abscess brought on by periodontal (gum) disease. In all these cases, appropriate dental treatment like decay removal and filling, root canal treatment or plaque removal may be necessary, depending on the cause and extent of the problem.

Regardless of what kind of pain you’re feeling, you should see us as soon as possible — in many situations waiting will only make the problem worse. The sooner we discover the cause, the sooner we can begin the right treatment to solve the issue and alleviate your pain.

ToothTroublesforNBAStarIsaiahThomas

All eyes were on Boston Celtics point guard Isaiah Thomas in Game 1 of the second-round NBA Playoff series against the Washington Wizards — and not just because he scored a game-high of 33 points! Even more dramatic was the moment his jaw collided with an opponent’s elbow, sending one of his front teeth flying out of his mouth and onto the floor.

Press reports said the Celtics’ team physician attempted to reinsert the tooth, but it didn’t remain in place when Thomas resumed playing the game. Over the next several days, he reportedly underwent a total of ten hours of oral surgery, and was fitted with a four-piece temporary bridge. A statement from the team noted that Thomas suffered “a complete fractured tooth and two other subluxed/shifted teeth… [He] will receive a permanent bridge at a future date.” So what does all that mean?

When we say a tooth is fractured, it means the crown (visible part) of the tooth has broken off from its roots, either above or below the gum line. Depending on the severity of the fracture, it is sometimes possible to save the natural tooth by performing a root canal to prevent bacterial infection, and then placing a crown (cap) on the tooth to restore its appearance and function. In more severe cases, however, the tooth can’t be saved and must be extracted.

Unfortunately, that isn’t Thomas’ only problem. He also has two subluxed teeth — that is, teeth that have shifted from their original position, but haven’t been knocked out of their sockets. Subluxed teeth often result from a severe blow to the mouth, and may be treated by stabilization or splinting. Team officials haven’t said exactly what was done during Thomas’ dental treatment, but it could very well have involved extracting the roots of any teeth that couldn’t be saved, and possibly placing dental implants in his jaw for future tooth restoration.

A dental implant is a small screw-shaped titanium post that is inserted directly into the bone of the upper or lower jaw in a minor surgical procedure. In time, it becomes fused with the bone itself, offering a sturdy anchorage for replacement teeth. One implant can support one replacement crown; two or more implants can support a number of replacement teeth joined together as a unit. This is called a dental bridge.

Bridges can also be supported by adjacent healthy teeth — but first, the outer surfaces of the crown must be prepared (reduced in size), so that the bridge can be attached over the remaining part of the crown. In many instances, implants are preferred because they do not compromise the structure of healthy teeth nearby.

Dental difficulties didn’t end Isaiah Thomas’ season — but an earlier hip injury that became aggravated finally did.  As unfortunate as this is, maybe now at least the NBA star will have a chance to let those injured teeth heal, and show up next season with a smile that’s as good as new.
