Dental onlay is used to repair rear teeth with mild to moderate decay or cracked and fractured teeth that are not damaged enough for a crown procedure.
Firstly, the dentist creates an impression of the tooth and send it to the laboratory, where the dental onlay will be made, using the specifications of the tooth that needs restoration. The porcelain the laboratory uses to create the dental onlay, will match the shade of the patient’s teeth.
When to use dental onlay?
Dental onlay is similar to inlay, but covers one or more cups or the entire biting surface of the tooth. An onlay is necessary when the extent of the damage is greater. This type of filling is a transition between the dental crown and the dental inlay.
Unlike the crown, there is no need to remove the undamaged part of the tooth. Dental onlay enables perfect fitting on the given surface. It is very durable and wear-proof.
The material of dental onlay
Dental onlay can be made of plastic, ceramic and gold.
The plastic onlay is fixed using a special glue in the cavity. At the closing point of the filling, after sticking, polishing is the next step, to ensure the perfect closure. The plastic onlay may discolor after a while.
Gold does not discolour at all. It has a long lasting life. Its colour is completely different from the natural tooth and it is much more expensive.
Ceramic dental onlay is the most aesthetic solution. It is almost invisible because it can fully adapt to the colour of the natural tooth.
How to care your dental onlay?
You need to care your dental onlay the same way you care for your natural teeth. Preserving and controlling oral hygiene is possible with the help of proper tooth brushing technique, soft toothbrush, flossing and regular dental check-up (half yearly).
