Initially, I tried to further secure the teeth in position with a wire staple alongside contact adhesive. The wire hook proved to make the tooth sit more loosely along the gum line, as it moved about inside the plastazote and rarely stuck into the head securely. I opted to use a blob of contact adhesive instead, having let the glue half cure in the air before applying it to the tooth. I then simply placed the teeth on the flattest areas of the gum line, though I sometimes had to angle the base of the tooth in order for it to sit properly. The bottom row was left to set for an hour before I was confident to turn the head upside down and set the top row of teeth. The top row proved more difficult to attach as the gum line is thinner, giving an uneven base for the tooth to attach to. Some of the teeth do not fit at a 90degree angle to the gums, and sit at juxtaposing angles like the teeth found in real crocodiles. In order to fit the teeth far enough back in the head, some had to sit along the brim of the bike helmet to blend in with the rest of the gum line. These teeth were slit down the centre so that they could slot on the thin line of the plastic.
The tongue was simply glued into the mask and at the tip where it joins the inside of the mouth. This was further secured with duct tape whilst the glue dried, though I removed the tape later as it would inevitably peel off. The glass eyes were also secured with contact adhesive run around the edges. For the right eye, fine filler was used to pack out the uneven surface behind. The eye was added while the filler was still wet for a good fit. This meant that some filler got onto the glass surface of the eye, which i removed using lighter fluid and a scalpol. Once the eye socket's surface was sanded back and cleaned up, I disguised the filler with black and copper acrylic paint. In response to the client's feedback, each eyeball is circled with black to help it stand out and appear more sinister looking.
Once the contact adhesive had set, there were a few gaps where the tooth had not met the gum line. I used a toothpick to fill these gaps with fine car body filler before running the filler around the base of each tooth for extra security. The yellow filler was then easily blended into the tooth and gums with white acrylic paint. As a finishing touch, black spots were added with a toothpick. This simulates the detail on my crocodile imagery and helps to merge the light pink of the gums into the green scales.
