What are Inlays and Onlays?
Inlays and onlays help restore moderately damaged or decayed teeth at the back of the mouth to provide strength and stability for normal chewing. They are made by a technician in a dental laboratory. The material used can be tooth-coloured porcelain, composite or gold.
Why do I need an Inlay or Onlay?
Sometimes you may need an inlay or onlay if a cavity is too big to hold a normal filling. Less invasive than a normal crown, both provide better resistance to the forces exerted during chewing and biting.
What is the difference?
An inlay repairs the central part of a back tooth whereas an onlay is bigger, repairing one or more cusps (raised points).
Frequently Asked Questions
An impression of the tooth is taken once the decay and damaged tooth has been cleared. This records the shape of the tooth being repaired and the teeth around it. A temporary inlay will be placed to protect the tooth while the laboratory makes the inlay. On the next visit the inlay will be bonded to the tooth and slight adjustments will be made to the bite if necessary.
Made from porcelain, plastic resin or gold, both inlays and onlays can last up to 5-10 years where oral hygiene is maintained and with regular check-ups to your dentist.
