Can I avoid a Root Canal?

The best way to avoid root canals and other invasive treatments is to get regular dental check -ups, Of course and focus on preventive dentistry and great home care. However, in case of very deep cavities that threaten the nerve/pulp of the tooth, we now have a great option! A biomimetic material called Theracal that helps "heal" the tooth from inside. Of course, this therapy cannot be used on teeth that are irreversibly inflamed or already necrosed. But, it is a great treatment for teeth with deep decay and even teeth with reversible inflammation! TheraCal LC is a light-cured, resin-modified calcium silicate filled liner designed for use in direct and indirect pulp capping and as a protective liner designed to be placed under other base materials. TheraCal LC performs as a barrier and protectant of the dental pulpal (the nerve canal of the tooth and root) complex, helping to stimulate secondary dentinal bridge formation in an effort to avoid root canal. TheraCal LC’s precise placement allows it's use in all deep cavity preparations. Its proprietary formulation allows for a command set with a light curing unit while maintaining ease of placement due to thixotropic properties. The proprietary hydrophilic resin formulation creates a stable and durable liner.

There are several studies showing that Theracal may be far superior to other agents used for "tooth healing". Here is one recent study...

Chemical-physical properties of TheraCal, a novel light-curable MTA-like material for pulp capping. Gandolfi MG, Siboni F, Prati C.


AIM: To evaluate the chemical-physical properties of TheraCal, a new light-curable pulp-capping material composed of resin and calcium silicate (Portland cement), compared with reference pulp-capping materials (ProRoot MTA and Dycal).

CONCLUSIONS: TheraCal displayed higher calcium-releasing ability and lower solubility than either ProRoot MTA or Dycal. The capability of TheraCal to be cured to a depth of 1.7 mm may avoid the risk of untimely dissolution. These properties offer major advantages in direct pulp-capping treatments.
