Inlays are much like fillings because they can seal a large cavity within the centre of a tooth. In cases where one or both of the corners — or “cusps” — of the tooth have worn away, an onlay can restore the full chewing surface of the tooth.
Your dentist will evaluate the condition of your tooth to determine whether an inlay or onlay is more appropriate for your needs.
A fitting for an inlay or onlay usually requires two appointments. During the first session, your dentist will prepare the tooth for the inlay or onlay.
Your dentist will then take digital 3D impression, using the revolutionary iTero® intraoral scanner, of the remaining tooth structure and send it off to a dental laboratory. This allows for a more accurate fit of the onlay. A technician will use the scan to produce your inlay or onlay. You will be given a temporary filling for protection and comfort.
At the next appointment, the dentist will remove the temporary filling and test the inlay or onlay to ensure it fits properly before cementing it into place.
Unless you choose gold, the most hard-wearing of the available materials, your new inlay or onlay will blend in with the rest of the tooth for a seamless appearance.
Also known as “indirect” restorations, a lab technician custom-makes your inlay or onlay and your dentist bonds it to the tooth. Conventional fillings, known as “direct” restorations, are materials applied directly to the affected tooth after decay removal.
If you have a medium to large cavity, moderate to severe breakage, or an old filling that no longer offers adequate protection, talk with your dentist at Mint Dental Clinic to find out if an inlay or onlay is a suitable option for you.
Although the structure must be reshaped, only decayed areas must be removed, and the fractured areas are smoothed. Our dentists take every precaution to preserve the natural tooth.
Once your anaesthesia has worn off, and the cement is set you can chew with the treated tooth. Our dentists will advise you on which foods are off-limits.
Inlays and onlays are strong and long-lasting. Conscientious daily brushing and interdental cleaning, in addition to professional cleanings and dental exams is all you need to make sure your restoration lasts for many years to come.
