A tooth can get damaged or need to be extracted as the result of injury or infection. When this happens, and a gap results in the teeth, a good option for filling in that gap or otherwise improving the look of a smile is with dental crowns and bridges. These are both dental prosthetics which are fixed onto existing teeth or implants.
Dental crowns can be used to:
In order to place a crown, the tooth receiving it must first be filed down to make room for it. The tooth and surrounding gum tissue are anesthetized (numbed) before this work begins. If the tooth has any decay, it will also be removed. Once the filing is complete, impressions are made of the tooth, which is used to create the crown. Normally, there is a waiting period needed during which the crown is created. However, because we have a ceramic lab on-site at Dental Health Centre, this waiting period can be minimized. The advantage is that a shade or adjustments can be made without the patient needing to go to another location It will be fitted on the tooth, the dentist making adjustments as necessary, then cemented into place.
If a tooth has been lost or been extracted and a gap has resulted, a bridge could be used to fill it. Leaving it untreated can allow the remaining teeth to move around into the empty space or even rotate. This can result in a bad bite or in the development of gum disease or temporomandibular joint (TMJ) disorders.
A bridge is made up of two parts – the pontic, or false tooth, and abutment teeth, or anchoring teeth, which hold the pontic in place. The abutment teeth are first treated to receive a crown. A temporary bridge is placed to protect the teeth which have become exposed after being filed down, as well as the gums. Once the permanent bridge has been created, it will be fitted and cemented into place. Multiple visits may be necessary to check the framework and bite of the bridge as well as to get it into the right placement.
