Porcelain Onlays

An onlay restoration is a custom made filling made of composite material, gold, or tooth-colored porcelain.  Porcelain onlays are popular because they resemble your natural tooth.  An onlay is sometimes also referred to as a partial crown.  Porcelain onlays are 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.

Dr. Thai has been my dentist for over 3 years now and I'm still fully satisfied with this office! The main thing I like about this office is that they really care about the patient.
So if you're looking for an office that pays attention to personalized care and a dentist that listens to your needs and concerns, this is the office for you!
They accept most insurances so if you're not sure if they are in network, make sure to give them a call and they will help you through the process!

I strongly disagree with Peter Z. I doubt that his review is for Dr Thai. I've been with Dr. Thai for 2 years and she never did what Peter Z has described. Dr. Thai is not a pushy person, I don't believe she would repeatedly up-sell unnecessary procedures to her patients. She is professional, knowledgable, skillful, experienced, down to earth, sincere, friendly. There are a lot of great values I found on her as an outstanding dentist.

I would highly recommend her to anybody.

This review is long overdue! I have been a patient of Dr. Thai for over 7 years now. I concur with the other reviews that she is sincere, friendly, and will go above and beyond to help with getting your dental needs taken care of. She would take the time to answer all of my questions and was very thorough with her cleanings, screenings, and overall dental care. The best thing about her is that she is gentle and patient. If you happen to see her during the holiday season, you may get a chance to try her homemade muffins or cookies. Her assistant told me that she loves to bake during the holidays, and she would share them with patients and colleagues. Her office even have cool dental items like bacon, pickle, and cupcake toothpaste/floss for you to try. So if you want a personalized and friendly office where the dentist knows all of her patients by name, then I highly recommend Dr. Thai. You won't be disappointed.
