Onlay Restorations

An onlay restoration is a custom made filling made of composite material, gold, or tooth-colored porcelain.  An onlay is sometimes also referred to as a partial crown.  It is made by a professional dental laboratory and is permanently cemented onto the tooth by your dentist.

Onlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma.  Onlays are an ideal alternative to crowns (caps) because less tooth structure is removed in the preparation of onlays.  Onlays are essentially identical to inlays with the exception that one or more of the chewing cusps have also been affected and need to be included in the restoration.

As with most dental restorations, onlays are not always permanent and may someday require replacement.  They are highly durable and will last many years, giving you a beautiful long lasting smile.

Reasons for onlay restorations:

  • Broken or fractured teeth.
  • Cosmetic enhancement.
  • Decayed teeth.
  • Fractured fillings.
  • Large fillings.

What does getting an onlay involve?

An onlay procedure usually requires two appointments.  Your first appointment will include taking several highly accurate impressions (molds) that will be used to create your custom onlay and a temporary restoration.

While the tooth is numb, the dentist will remove any decay and/or old filling materials.  The space will then be thoroughly cleaned and carefully prepared, shaping the surface to properly fit an onlay restoration.  A temporary filling will be applied to protect the tooth while your onlay is made by a dental laboratory.

At your second appointment, your new onlay will be carefully and precisely cemented into place.  A few adjustments may be necessary to ensure a proper fit and that your bite is comfortable.

You will receive care instruction at the conclusion of your treatment.  Good oral hygiene practices, a proper diet, and regular dental visits will aid in the life of your new onlay.

Testimonials

Dr. Leong is an amazing dental professional. I've been seeing her for a number of years and she has always been effective, responsive, personable and caring. She managed my Invisalign process and did a great job from start to finish. She's very gentle so pain is never in the equation during my visits with her. She's also just a wonderful person. I consider her both my dentist and my friend. I would recommend her to anyone who's looking for a skilled dental professional.

I have been consistently happy with how Dr. Leong and her staff have cared for my teeth. AND, I've had A Lot of Work for Dr. Leong to do with my teeth! Shortly after my first cleanings, I had cavities to fill, then a molar cracked and I had to get a crown, which Dr. Leong did really well (better than my last dentist for sure!)... Given these positive experiences, I trusted Dr Leong to create Veneers for 8 of my upper front teeth, to totally transform my smile! I am very happy with my smile, get lots of compliments, and have confidence that the work will last me a long time (probably longer than my teeth would on their own... She not only did expert work to prepare my veneers and my teeth, but she also went above and beyond to make sure everything fit and felt right for me.

Dr. Leong is hands down the best dentist I've ever had. She is extremely friendly and knowledgeable. She educated me about the right way to take care of my teeth without being pushy or judgmental. She explained everything she was doing very thoroughly so that I understood my own health better. She never made me feel rushed and she was never pushy trying to sell me dental work I didn't need, which has happened to me many times with other dentists. She and her staff were top notch.

My appointment was exactly on time and Anna at the front desk had already gotten my insurance information without me having to fill out anything. Everything was very well organized and we started my exam right away.
