CROWNS AND BRIDGES
Today most crowns are made from alloys. Sometimes these alloys are coated with a layer of porcelain for natural appearance.
The patient is given a temporary crown to wear while the permanent one is being constructed. After a «try-in» appointment any necessary changes are made and the crown is put into place.
When a single crown is not sufficient to mask the defects and the patient has enough natural teeth remaining, a fixed partial denture (bridge) can be used.
For some dental problems, for example, insufficient remaining teeth affected by periodontal disease, a removable partial denture may be recommended. Both fixed and removable partial dentures depend on the existing teeth for their support, and caution must be taken to avoid damage to these supporting teeth. Thorough brushing and flossing, eating a balanced diet, and visiting the dentist regularly will help to ensure the health of the remaining teeth. Moreover, some precautions are necessary to avoid fracturing the replaced teeth.
