Your dentist will temporarily place the dental veneer on your tooth before permanently cementing it to confirm that it will fit correctly, and that the colour will match your existing teeth. The veneer may be trimmed multiple times to achieve the right fit.  To prepare the tooth for the veneer, the tooth will be cleaned, polished and etched to encourage a strong bonding process. Your dentist will also apply special cement to the veneer before fitting it to your tooth.  Once the veneer is properly positioned on your tooth, a special light beam will be used to activate chemicals in the cement, causing it to quickly harden or cure.  Finally, your bite will be evaluated and any necessary last adjustments will be made.  Your dentist may ask you to return for a follow-up visit in a couple of weeks to see how your gums are responding to the veneer.
