Dental Crown Procedures

History and examination of patient, mouth and individual tooth.

The dentist will determine whether is necessary to place a crown on that particular tooth and you should understand what kind of treatment you will receive in the future.  Patient should agree with the charged fees and should clear any doubts regarding the treatment with the dentist. Crowns are usually placed on teeth which have good prognosis and patients who have excellent oral hygiene.

Study models/photographs.

An impression of your mouth is taken and after it being casted, we can observe the arrangement of your teeth, condition of the individual tooth. Having impressions taken might be an unbearable process but it is a necessary procedure so that the de

ntist can plan the crowning procedure beforehand. Photographs are usually taken to record the previous appearance of the tooth.


Sometimes your dentist will show you how your tooth will be look  like with the crown. This is called diagnostic wax up, in which wax will be added and carved into desired shape/contour  on the study model we have taken earlier.Shade taking is a very important procedure as it is best to have our crowns resemble the natural appearance of your teeth. Normallyshade taking is taken before any tooth preparations as eyes can be strained at the end of the day and it is taken under broad day light or artificial light. Various shade guides and devices is available to enable the dentist to find the best shade for you.

Tooth preparation.

Temporary crowns are meant to last for a short period until the actual crown is constructed. Temporary crown is placed to protect the prepared dentine, to maintain your appearance, to maintain occlusion, and etc.After that, your dentist will normally ask you to bite into a piece of wax or a material which is delivered using a automix gun.

Final impression.

After tooth preparation, a final impression is taken to record the prepared tooth surface so that the technician will be able to construct a well fitting crown.
