Teeth are harder to burn than bones, but even teeth can be totally destroyed if a fire burns hot enough and long enough:

...The destruction of teeth by fire is a matter of professional interest to forensic dentists involved in the identification of bodies. A study conducted by German forensic dentists in 2001 found the following:
- After 30 minutes in fires with temperatures of 752 degrees Fahrenheit (400 degrees Celsius) the front teeth are totally destroyed. The molars (the grinding teeth in the back of the mouth) start to crack.
- At between 45 and 70 minutes in fires with temperatures between 1832 degrees Fahrenheit (1000 degrees Celsius) and 2012 degrees Fahrenheit (1100 degrees Celsius), all the teeth are totally carbonized. 3
- In a civilian crematorium furnace, a temperature between 1400 to 2100 degrees Fahrenheit (760 to 1150 degrees Celsius) is generated to ensure the disintegration of the remains. Even then teeth and some bones are still intact and are crushed in a machine.... 4
BUT, fire investigators have said that if the children were in the house, there should be bone fragments that were at least a couple of inches long. Also, the children and the grandparents could have been in different parts of the house, but still, it seems odd that the grandparents' bodies were found and identified almost immediately (as was a third body, originally thought to have been a child, but it turned out to be a dog), and yet there's not even a tooth left of one of the children.
