Although toothaches are common, not all tooth pain originates from the same source. But regardless of its cause, you need to take prompt action to find out and begin treatment.
Sensitive teeth, for example, usually cause a quick stab of pain when you eat or drink something hot or cold or when you bite down. If the pain lasts only a second or two, you may have a small area of decay in a tooth, a loose filling or an exposed root. The latter often occurs either because of over-aggressive brushing or periodontal (gum) disease. In both cases, the gums may have shrunk back or receded to expose the root surface.
A sharp pain when biting down may be a sign of decay or a loose filling; it could also mean you have a fractured or cracked tooth. For any of those causes, you'll need treatment to repair the problem and relieve the pain.
You may also experience a lingering tooth pain ranging from dull to sharp, or localized to one tooth or seeming to radiate from a general area, such as above the upper jaw. There are a number of possible causes, but two prominent ones are an abscess (a localized area of infection that's become inflamed) or deep decay within the pulp, the heart of a tooth.
This usually calls for a root canal treatment for the affected tooth. In this procedure we drill an access hole into the pulp and clear it of infected and dead tissue. We then fill the empty pulp chamber and root canals with a special filling and seal the access hole. Later, we bond a permanent artificial crown to the tooth to further protect it from re-infection.
Whether your pain is momentary or lingering, dull or sharp, you should see us as soon as possible to determine its cause. You should still see us even if sharp, lingering pain goes away — this could simply mean the infected nerves in the pulp have died but not the infection. The sooner you have the cause of your pain treated, the better your chances of a happy and less costly outcome.

The change from primary teeth to permanent is an announcement to the world that a boy or girl is "growing up." "Growing up," though, is still not "grown"—the new teeth are still in a period of development that can affect how we treat them if they're injured or diseased.
While a new tooth erupts with all its anatomical layers, the middle dentin is somewhat thinner than it will be after it matures. The pulp, the tooth's innermost layer, produces new dentin and gradually increases the dentin layer during this early development period. While the pulp continues to produce dentin over a tooth's lifetime, most of it occurs in these early years.
To prevent or stop any infection, we would normally perform a root canal treatment in which we remove the pulp tissue and fill the empty pulp chamber and root canals. This poses no real issue in an older tooth with mature dentin. Removing the pulp from an immature tooth, though, could interrupt dentin development and interfere with the tooth's root growth. Besides a higher risk of discoloration, the tooth could become more brittle and prone to fracture.
That's why we place a high priority on preserving a younger tooth's pulp. Rather than a root canal treatment, we may treat it instead with one of a number of modified techniques that interact less with the pulp. Which of these we use will depend on the extent of the pulp's involvement with the injury or disease.
If it's unexposed, we may use a procedure called indirect pulp therapy, where we remove most of the tooth's damaged dentin but leave some of the harder portion intact next to the pulp to avoid exposure. If, though, some but not all of the pulp is damaged, we may perform a pulpotomy: here we remove the damaged pulp tissue while leaving the healthier portion intact. We may then apply a stimulant substance to encourage more dentin production to seal the exposure.
These and other techniques can help repair an injured young tooth while preserving most or all of its vital pulp. Although we can't always use them, when we can they could give the tooth its best chance for a full life.

There’s one sure thing about tooth decay: you can’t ignore it. In fact, the best outcomes result from finding it early and treating it before it enters the pulp in the center of the tooth, often a filling or similar treatment.
If it does advance to the pulp, you may need a root canal treatment to save the tooth. This is a moderately invasive procedure where we access the pulp and root canals, tiny passageways leading to the root and supporting bone. We then remove all the diseased tissue and fill the empty pulp chamber and root canals with a special filling. Later we’ll crown the tooth for added protection against future infection or fracture of the tooth.
But there’s also another less-invasive method than a root canal called pulp capping. It’s only appropriate to use, however, if the pulp has become exposed or almost exposed by decay, but hasn’t yet shown signs of disease.
Pulp capping can be either direct or indirect. We use direct pulp capping if the healthy pulp has been exposed by the disease process. We first isolate the tooth from the rest of the mouth to prevent contamination and then proceed to remove all of the tooth’s decayed dentin structure. We then apply a biocompatible material directly over the pulp to protect it from further decay and to facilitate healing. We then restore the tooth, usually with a filling, to its proper function and life-like appearance.
When the pulp is threatened by decay but not yet exposed, we may then use the indirect method. In this approach we first remove most of the decayed dentin, but leave a small amount next to the pulp to keep it covered. We then treat this remaining dentin with a material to help it heal and re-mineralize, followed by a temporary filling of the tooth. A few months later we’ll remove this filling and inspect the treated dentin. If it has regenerated sufficiently, we remove any remaining decay and permanently restore the tooth.
As we said, pulp capping is only used with patients with deep decay whose pulp tissue is healthy. But when we can use it we can avoid some of the permanent alterations that often come with a root canal treatment and still save the tooth.
