Dental inlays or onlays refer to porcelain/ precious metal fillings that are used to close up the gap created by a decayed tooth that has just been treated. When a tooth decays, the dentist removes the affected area, treats and cleans the tooth. The resultant cavity that is created needs to be filled.
This is where dental inlays or onlays come into play. The porcelain filling is specially made to order in a laboratory, and are then bonded to the tooth in question. The advantage of this filling is that it matches the colour of the tooth, does not stain, covers most of the tooth, and looks and feels completely natural.
Other options for fillings are gold and composite resin, but porcelain inlays are the most popular ones used today.
Frequently Asked Questions
What are Inlays and Onlays?
Inlays and Onlays are types of dental restorations used to repair damaged or decayed teeth, particularly in the back teeth (molars and premolars). An inlay fits within the grooves of a tooth, while an onlay extends over one or more cusps of the tooth. Both are custom-made from materials like porcelain, composite resin, or gold, and are designed to match the natural color of your teeth.
When are Inlays and Onlays recommended over fillings or crowns?
Inlays and Onlays are recommended when a tooth has too much damage for a regular filling but not enough to require a full crown. They provide a more durable and long-lasting solution than fillings, particularly for larger cavities or areas with significant wear. Inlays and Onlays preserve more of the natural tooth structure compared to crowns.
What is the procedure for getting an Inlay or Onlay?
The procedure for getting an inlay or onlay typically involves two visits. During the first visit, the dentist removes the damaged or decayed portion of the tooth and takes an impression to create the custom restoration. A temporary filling may be placed to protect the tooth. At the second visit, the inlay or onlay is bonded to the tooth, ensuring a precise fit and natural appearance.
How long do Inlays and Onlays last?
Inlays and onlays are durable dental restorations that can last anywhere from 10 to 30 years, depending on several factors. Their longevity largely depends on the quality of the material used (such as porcelain, composite resin, or gold), the patient’s oral hygiene practices, and habits like teeth grinding or chewing hard objects. With proper care, including regular dental check-ups, good oral hygiene, and avoiding habits that can damage teeth, inlays and onlays can provide long-lasting results and help preserve the tooth’s natural structure.
