The sooner you get treated for tooth decay, the less likely you'll lose your tooth. That could mean a simple filling—or you might need a root canal treatment if decay has reached the inner pulp.
There's also another procedure for advanced decay called pulp capping. It's a bit more involved than filling a cavity but less so than a root canal. We can use it if decay has exposed or nearly exposed the pulp, but not yet infected it—otherwise, you may still need a root canal treatment to remove the diseased pulp tissue.
There are two types of pulp capping methods, direct and indirect. We use direct pulp capping if the pulp has been exposed by decay. After isolating the tooth to protect other teeth from contamination, we remove all of the decayed dentin up to the pulp. This may cause some bleeding, which we'll stop, and then clean and dry the tooth area.
We'll then apply a protective biocompatible material directly over the pulp to promote healing and protect it from further infection. We then restore the tooth's appearance and function with a life-like filling.
We use the indirect method, a two-part process separated by six to eight months, when the pulp tissue is close to the surface but not yet exposed. We initially remove the majority of decayed tooth structure, but leave some of it in place next to the pulp chamber. Although this remaining dentin is softened and decayed, we'll treat it with antibacterial chemicals, then cover it with a biocompatible material and a temporary filling.
Over the next several months the treated structure has a chance to re-mineralize as it heals. We then remove the temporary filling and assess the level of healing progress. If the regenerated dentin appears healthy, we can then remove any remaining decay and restore the teeth as we would after a direct pulp capping.
At the very least, pulp capping could buy your affected tooth time before a root canal will finally be needed. Under the right circumstances, it's an effective way to save an otherwise lost tooth.

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.
