First appointment

At the first visit, dentist will examined your teeth. Sometime X-rays are taken if decay is found or there is a risk of infection or injury to the tooth’s pulp, in that case you may require first teeth filling or a root canal treatment

Your dentist will need to anesthetize (numb up) both your tooth and the gum tissue that surrounds it. So you will not experience any pain during whole procedure.If your teeth already root canal treated, you may not need of any anaesthesia.

Dentist put a paste or putty like material on a tray and put on your mouth for 1-2 until it gets set and remove it, if your shaped tooth is not recorded properly on material dentist may take new impression, because only accurate impression gives accurate crown fitting.

Then dentist record your colour of teeth with vita shade guide® which should match with natural tooth colour. The crown should match that of the tooth and surrounding teeth so that it is not noticed when it is placed inside the mouth. If you select a metal crown this step is not required.

At last a temporary crown is usually placed over the tooth to protect it until your final crown has been fabricated and is ready to be fixed on teeth. Final crown fabrication will take 3-10 days depending on type of crown you selected.

Temporary crown is cemented with temporary cement only so it will easily pop up while brushing, flossing and eating so you have to be careful while wearing a temporary crown. You should avoid sticky and hard foods and eat using the opposite side of your mouth.
