The left mandibular second and third incisors and canine affected by enamel hypoplasia. sensitivity to heat, cold and pressure, especially in younger animals. The goal of treatment is to seal the dentin tubules responsible for sensitivity with a dental bonding agent, smooth down the dental ridges that accumulate plaque and tartar with a white stone bur on a water-cooled high-speed handpiece, and restore the tooth with composite restoration. Unfortunately the composite restoration rarely lasts because of shearing forces. Repeated application of dental boding agents every six months until the dog is 2 years old allows for more dentin formation and increases the distance between outside influences and the pulp, decreasing sensitivity. Placing metallic crowns to protect larger teeth generally creates Figure 7A. A left mandibular first molar affected by enamel hypoplasia. long-term pain-free solutions. Metallic crown restoration should be considered when treating the eight larger teeth, including the canines, upper fourth premolars and lower first molars. Extraction of the affected teeth is usually not indicated as long as there is no evidence of endodontic disease (Figures 7A-7E). Figures 7D and 7E.
