BLEACHING TEETH.

Dr. W. H. Atkinson. D. S., of New York, gives tlia lollowing directions for treating discoloured teeth : To bleach a tooth discoloured by the loss of its pulp: Carefully clean it out to the end of the root, going through the apex in the ahvai/s present latent afews at the end. After drying out as well as you can, proceed to fill nicely all the length of the canal in the root and the pulp chamber with oxychloride of zinc. As soon as it is well hardened excavate out all the discoloured dentine that can be spared without weakening the tooth. Then fill the nerve chamber with powdered alum and wet it with Labaraque's solution of chloride of" sodiurr (such as the laundress uses in washing). This will bleach any tooth that in stained by vegetable colour. Now dry well and fill with such shade of oxide ot zinc as will restore normal colour. When hard cut out the surface and cover with gold. Iu case iron be the colour agent, it may be removed by dissolving a frw crystals of oxalic acid in the cavity ; afterwards proceed as before directed. Faithfulness in following these instructions, the doctor says, will result in satisfaction to patient and practician by perseverance.
