This is the dental photograph of a 24old year male who is a having dental malocclusion but he is not aware of his problem. He had come to me for some other dental complaint.
Now you can see in the above photograph that when he clenches his upper and lower teeth, the lower teeth are hardly visible. We call it closed bite –or Deep Bite. It is a type of dental malocclusion ie the relationship of upper and lower teeth is not normal. And problem is further compounded by the upper canine teeth in lock-bite ie instead of lying outside to the lower canines, these are placed lingually to the lower canines ie lying inner to lower canines.
Apart from being malocclusion which hampers the functioning of dental arches, is harmful for the overall well-being of the dentition because such irregular relationship of teeth leads to trauma to the healthy teeth which lead to periodontal disease, this condition affects the appearance of an individual- it imparts an aged look to the person.
