Excess melanin can cause discolouration on the gum, which although not detrimental to the health, may be considered by the patient as not very aesthetically pleasing. People who have darker skin are more susceptible to melanin build up on the gums.
Gum discolouration can also be caused by amalgam (silver) filling particles that have absorbed into the gum. Certain types of medication and smoking may also cause the gums to darken.
Melanocytes (cells in the soft tissues which are responsible for producing melanin) are targeted by the laser and their rate of producing melanin is dramatically reduced. The gum bleaching procedure is quick and painless and in most cases. The treatment can be completed in one visit, allowing the patient to leave the surgery with pink gums again. Depending on the amount and type of pigmentation, more than one visit may be needed.
