Extraction might not be the only option when it comes to restoring dental health in patients that present with dental maladies. In many cases tooth repair can be an effective solution.
This dog presented with enamel hypoplasia. This condition occurs secondary to disrupted deposition of the enamel matrix in patients between 9 and 12 weeks of age caused by infection, poor nutrition or trauma. The condition can affect one or several teeth and may be focal or multifocal. The crowns of affected teeth have areas of normal enamel next to areas of hypoplastic or missing enamel, as pictured below.
What approach would you take to resolve this condition for the pet?
A. Restore the tooth with light-cured acrylic resin
B. Extract the tooth
C. Restore the tooth with light cured acrylic resin plus a metallic crown for added protection
D. Perform a root canal

If you chose A (restoring with light cured resin) or better C (restoring with acrylic and a metallic crown) you are correct!
Repair consisted of ultrasonic cleaning and polishing followed by application of phosphoric acid as an etchant. Light cured acrylic resin was added over the dental bonding agent and adhesive on the prepared areas void of enamel to protect the underlying dentin and pulp.
The canine was then prepared for crown restoration followed by an impression, which was sent to the dental laboratory for crown fabrication. Two weeks later the crown was cemented to further protect the tooth.
