Someone with a dark front tooth. We have all either seen it or experienced it ourselves. It usually happens after trauma in youth. With all the rough housing children do, it is surprising that there are not more adults with darkened front teeth.
Teeth are housed in sockets in the upper and lower jaws. They are not directly attached or fused to the jaw, as dental implants are. Between our teeth and the jaw bone is the periodontal ligament. This ligament or space acts like a shock absorb-er. It allows for some normal tooth movement. The periodontal ligament is also part or the gum disease story, but that’s a different story than this dark tooth tale. If the trauma to teeth is minor, the periodontal ligament can usually absorb the mild shock with little or no long term damage. If the tooth or teeth are so forcefully moved or luxated in the socket, the neurovascular bundle can be torn thereby causing a disruption or cessation of blood supply to the tooth’s pulp (commonly called the nerve.) If, as a result of this trauma, the pulp’s blood supply is terminated, the pulpal tissue will necrose, die, rot. The tooth’s change in color occurs after the decaying tissue’s by products permeate. If treatment is delivered early in this process, simple internal bleaching after root canal therapy may restore the natural color in the least invasive way possible. If the situation is not addressed for months, years or decades, root canal therapy and internal bleaching many not be the treatment of choice.
It is nearly impossible to match even the best zirconia based crown to a natural tooth in the midline. Although not perfectly undetectable, the improvement achieved here in my Palm Harbor Dentist office is remarkable.
