Inlays and Onlays

Inlays and onlays are used to restore teeth that are too decayed to repair with a regular filling, but not damaged enough to require a dental crown. An inlay is placed on the biting surface, or center of the tooth, while a dental onlay extends outside the cusps of a tooth. Made of composite, metal, or porcelain materials, durable inlays and onlays support a weakened tooth so it can retain strength and normal function.

Durable, Natural-looking Inlays and Onlays

Dr. Richard K. Hada provides durable, natural-looking inlays and onlays at his state-of-the-art dental practice in Mission Viejo, CA. They are usually recommended when a tooth is too damaged to repair with a filling, but not damaged enough to warrant a dental crown. Unlike dental fillings, inlays and onlays are fabricated before being fitted and bonded to a tooth. An inlay replaces a central portion of the chewing surface of a tooth, while an onlay can also replace the cusps, or outer edges of the chewing surface. To learn more, or to schedule an appointment, contact Hada Family Dental today.



Made from high-quality dental porcelain, inlays and onlays support a weakened tooth following treatment for damage or decay. Placing an overly large filling in a tooth can actually weaken its structure, leaving it susceptible to damage in the future. On the other hand, placing a crown (also called a cap) requires significant alteration of a tooth. Inlays and onlays can provide an ideal solution that gives a tooth the support it needs, while requiring only moderate alteration of the tooth.


Candidates for inlays and onlays have a tooth with too much damage or decay for successful treatment with a dental filling, but enough healthy tissue to make a dental crown an excessive solution. If the damage or decay does not affect the outer edges of the chewing surface, the patient will likely be a candidate for an inlay. When decay affects a cusp, or edge of the chewing surface, an onlay is required. These restorative dentistry techniques can also be used when old fillings require removal and replacement.


Because your restoration will need to be fabricated in a laboratory, it will take two appointments to complete your inlay or onlay treatment. During your initial appointment, Dr. Hada will numb the tooth with local anesthetic so you will be comfortable. Next, he will prepare the tooth by cleaning it and removing any decay or damage. Next, he will take an impression of the tooth with dental putty. The impression will be sent to Dr. Hada’s dental laboratory, and it will be used to guide technicians as they create the inlay or onlay. In the meantime, you will wear a temporary restoration. The second appointment will be scheduled when your inlay or onlay is ready. At that time, Dr. Hada will remove your temporary restoration and bond the inlay or onlay in place.


Inlays and onlays provide a wealth of benefits:

  • They are a more conservative treatment than dental crowns.
  • Inlays and onlays restore form and function.
  • They are very durable, and can last for 20 years or more.
  • Each inlay and onlay is custom-crafted to achieve a natural-looking result.
