What are the symptoms of dentinogenesis imperfecta type ii?

Shell teeth: Dentinogenesis imperfecta (hereditary opalescent dentin) is a genetic disorder of tooth development. This condition causes teeth to be discolored (most often a blue-gray or yellow-brown color) and translucent. Teeth are also weaker than normal, making them prone to rapid wear, breakage, and loss. Type iii shows thin dentin and extremely enormous pulp chambers and are known as shell teeth.

YelloW, brown, gray: Dgi type ii has only dentin abnormalities and no bone disease. Both primary and permanent teeth have unusual translucent and opaque appearance and the colors associated can range from yellow to brown and gray. The reason is the abnormal dentin beneath the enamel. The enamel can sometimes fracture easily because again the dentin below it is abnormal.
