Is it uncomfortable or painful to have an onlay made?
No. The procedure is not painful because a local anaesthetic is used during the preparation of the tooth and the taking of the impression.
What are the benefits?
- Onlays are very strong and usually last much longer than fillings.
- They are especially suitable for the chewing surfaces of back teeth and can mimic better the shape of occlusal and interproximal surfaces of natural teeth.
- Better contact points with adjacent teeth make onlays better cleansable and minimise the chance of tooth getting secondary decay long term.
What role does the dental technician play?
- The dental technician plays an important part in the making of an onlay. It takes skill and experience to fabricate an onlay from the impression that the dentist provides. The onlay must be very precise in its colour and dimensions.
- The impression that is received from the dentist is used to make a plaster or stone cast of the prepared tooth or teeth. The cast is a copy of the tooth or teeth.
- It allows the technician to make an onlay over the exact copy of a prepared tooth.
- The technician will use the same shade/colour guide as the dentist, to ensure that the replacement onlay will match the colour of the adjacent teeth.
