A crown is applied to a tooth that has suffered excessive material loss, due to decay, fracture or other similar reasons, that cannot be restored with composite/porcelain fillings. Depending on the patient’s preference, a crown may contain metals (alloys of precious or non-precious metals) or be metal free (zirconium)
Utilized to fill a gap caused by the absence of one or more teeth by downsizing the supporting teeth, a bridge is used when implants cannot be fixed or not preferred by the patient. Like the crown, the choice of the base and the type of porcelain used depends on the size of the gap and the patient’s preference.
How are crowns and bridges produced?
Before a crown or a bridge can be fitted, the tooth (or teeth) must be reduced in size so that the prosthesis will fit over it properly. After the tooth reduction procedure, the dentist will take an impression to provide an exact mould. If porcelain is the selected material, the dentist will also determine the correct shade, to match the colour of your existing teeth. Using the impression, a dental lab makes your crown or bridge in the material specified by the dentist. A temporary crown or bridge is put in place to cover the tooth during that time. When the permanent crown or bridge is ready, the temporary prosthesis is removed, and the new one fitted and bonded over the tooth or teeth.
How long do crowns and bridges last?
Crowns and bridges can last for many years. The most important step you can take to ensure the longevity of your crown or bridge is to practice good oral hygiene. Keep your gums and teeth healthy by brushing with fluoride toothpaste twice a day and flossing daily. Also, see your dentist regularly for check-ups and professional cleanings.
