This fellow’s tooth was wacked when he was young. Wear a mouthguard when playing sport please guys! The existing filling was leaking and broken and the tooth had gone dark. The blood in teeth stains when the nerve dies, and also the medicaments used in root fillings may stain the tooth. Ideally the tooth would be bleached as a conservative option. The filling was failing so the next best option would be a crown. Unfortunately this tooth is on its way out – it is so hollowed an weak it wont hold a crown but we had to do something because the current filling is failing.
We built him a new tooth using a carbon fibre post into the root, and bonding dental composite resin over the top. It is much cheaper than a crown, and if the tooth fails he is looking at a gap, denture, or implant. Hopefully we have delayed these options for some time to come and given back a smile.
