If you have a cavity or broken tooth, most Atlanta dentists will give you one of two options to repair it, either a filling or a full coverage crown. With a filling, you can repair an area inside of a tooth, such as when a cavity is present. If too much of the tooth is damaged or decayed, filling the thin shell of enamel that is left simply puts you in a position of additional fractures and breakage from everyday wear. It just can’t hold up to normal use.

On the other hand, a crown covers your entire tooth surface. It requires the tooth to be gently prepared and reshaped so that a “cap” can be bonded over it without looking or feeling too bulky. If your cavity is too large for a filling, most of the time the dentist will use a crown.

The Missing Link

Fortunately, there’s another restorative dentistry option that might be more appropriate for your moderately damaged tooth. An inlay or an onlay. Sometimes referred to as a “three-quarter crown,” inlays and onlays restore a larger portion of your tooth than a filling can. However, it doesn’t cover the entire surface of your tooth the way a crown would. Instead, the lab-formed porcelain “filling” is customized for each patient. It restores the damaged area but leaves healthy enamel intact.

The design between the two is just slightly different. An inlay extends further inside the grooves of a tooth, while an onlay rests over a greater portion of the “cusps” to rebuild the chewing surfaces. The benefits and treatment process is essentially the same for each.

What are the Benefits of Inlays and Onlays?

Advantages of inlays and onlays make them a great selection if you need more than a filling but don’t quite require a crown. Instead of crowning the tooth, an inlay or onlay allows you to:

  • Preserve more tooth structure, as healthy enamel does not need to be drilled away for a crown
  • Maintain structural integrity for biting and chewing
  • Enjoy improved oral hygiene, as there is no “crown margin” circling along the gumlines
  • Improve aesthetics with custom matched porcelain
  • Have a more natural appearance to the tooth
  • Prevent the enamel from fracturing even further, so you can avoid root canal therapy

Unfortunately, placing a crown on a tooth requires the entire surface of enamel to be drilled away (or “prepped”) so the crown will fit properly and not be bulky. If your enamel is healthy, it’s easy to see why removing it can sound extreme. However, if your general dentist isn’t familiar with inlays and onlays, the only option left may be to have the tooth crowned. Seeing a specialist, such as a prosthodontist, can make getting an inlay or onlay as simple as possible, giving you the chance to save your enamel and your smile.

Is This a New Procedure? Why Don’t Many Dentists Offer Them?

Inlays and onlays are not new. In fact, they’ve existed for decades. Unfortunately, not many dentists choose to use them in their practices. This most likely because the procedure is just as time and energy-intensive as a crown. Years down the road, if the tooth wears out, the tooth may need a crown anyway. This kind of reasoning typically causes general dentists to bypass the inlay or onlay altogether.

However, inlays and onlays are very popular with restorative experts like prosthodontists. The American Dental Association recognizes the prosthodontic specialty as dentists that have received an additional two to three years of formal education in restorative and prosthetic dental techniques.

Attaining a higher level of training enables prosthodontists to perform less frequent procedures (like inlays and onlays) with a greater level of expertise than a general dentist. They should not be confused with a “cosmetic” dentist, as cosmetic dentistry is not recognized by the ADA as a specialty. Prosthodontists are the most highly skilled dental specialists when it comes to restorations like inlays, onlays and cosmetic treatments such as porcelain crowns or veneers.

The Treatment Process

Having an inlay or onlay procedure has many similarities to placing a crown. However, since most dentists do not receive extensive training in the procedure, it’s best to see a prosthodontist. With the right dentist, you can ensure that your procedure will be performed as efficiently and successfully as possible.

First, your tooth will be thoroughly numbed so that you do not experience any discomfort. Then, the damaged or decayed area of your tooth will be removed, leaving healthy enamel in place.

Next, an impression is made of your tooth. We then create a model of the tooth and send it to our lab. There, the lab technician hand-designs a customized inlay or onlay to reflect the unique needs of that specific tooth. A temporary filling will be placed over your tooth to prevent any sensitivity while you wait for the custom restoration to be made. About 10 business days later, your inlay/onlay will be ready.

Finally, the temporary filling is removed, and your inlay/onlay is cemented permanently into place. Your bite is assessed to ensure that there are no irregularities that could alter the way you chew or cause TMJ concerns.

What Are They Made Of?

Traditionally, inlays and onlays have been made of either porcelain or gold. Gold is sometimes preferred in areas where chewing forces are greater, but they pose an aesthetic concern. Thankfully, porcelain dental materials have tremendously improved over the past several years, making them more durable and cosmetically pleasing. It’s now possible to use porcelain for nearly all of the inlay and onlay procedures we perform in our Atlanta office.

With a porcelain restoration, we’re able to closely match the shade of the inlay or onlay to the color of your natural tooth. This allows the restoration to blend in seamlessly with the entire tooth, giving us the option of using them just about anywhere in the mouth. When you talk or smile, other people won’t be able to tell that anything is there.

Is an Inlay or Onlay Right for You?

An inlay or onlay is a great option if you’ve experienced:

  • A large, failing or leaky filling
  • Fractured/chipped teeth
  • Fillings that fall out over and over again
  • Cavities that are too large to fill

Ultimately, the unique health, integrity and existing damage to a tooth will determine whether or not an inlay/onlay is appropriate. That being said, most Atlanta dentists will not suggest inlays and onlays because they simply do not perform the procedure on a regular basis. Instead, they move to a more comprehensive and invasive crown.

Fortunately, our prosthodontists at AIDA are experts at placing inlays and onlays. If you’re considering having an inlay or onlay made to save your tooth, you want someone with the specialized skill and training for this less-than-common procedure. This is instead of a “cosmetic” dentist that only does a few each year.

Dr. Zelby was recommended to me by both my dentist and periodontist. I could not agree more. the kindness, caring, and professionalism that I experienced at Aesthetic & Implant Dentistry of Atlanta is above and beyond. I highly recommend Dr. Zelby, his assistants, and the staff. I couldn't be happier with my new teeth and wish I had done this years ago! five stars to you guys

Catherine W.

Everything about my experience was enjoyable. I felt like the practice used all of the most advanced and best technology out there which gave me a wonderful feeling of confidence. They were very professional and straight forward and I have never had a better dentistry experience. I'd highly recommend checking them out if you're looking for a new dentist. They're friendly and efficient and they really do know what they're doing there.

Meghan D.

Dr Zelby has been my dentist now for almost 17 years. Not only is he a really nice person, his dentistry is completely top notch. If you need any restorations, I don't think that there is another place to even consider. You'll be amazed with his work!

Brian S.

Dr. Levine was great, and Dr. Zelby stopped by and answered some questions I had about sheering forces on enamel. They were both very friendly, and the hygenist (whose name I forget, unfortunately) gave one of the most thorough cleanings I've ever had. The office was clean, the devices all seem shiny and well maintained, and overall it was a great experience

Benjamin S.

After going to another dentist, doctor Zelby was able to fix my front two teeth so that the front two teeth were back to the same length and color. I'm so thankful he was able to make them look normal again. Dr. Zelby and his staff are so pleasant to be around as well. I highly recommend this office if you have a major problem with your teeth that need to be fixed. He can get it done and he will make sure you are happy.

Carrie G.

I had been going to the same dentist for many years and switched to Aesthetic and Implant recently. My experience with Dr Levine was incredible. I cannot be happier with the decision I made. The cleaning and other services I received were well above and beyond any other I have ever had. Highly recommend this practice to everyone!

Matthew G.

Couldn't be happier! Absolutely worth the travel time. Dr Zelby is without doubt the best - caring, knowledgeable, reassuring and very professional. Couldn't ask for better dentistry. Staff also very competent and professional. Beautiful, clean environment

Diane W.

Megan is the best dental hygienist I’ve ever had. She does a phenomenal job keeping your teeth clean, is super nice, and makes you feel right at home. The whole staff is very friendly and I couldn’t recommend this place enough!
