What are the differences between inlays, onlays, and fillings?

Q: What are the differences between inlays, onlays, and fillings?
A: Fillings repair minor cavities or damage within the tooth structure, while inlays and onlays are custom restorations for larger areas of decay. Inlays fit inside the tooth cusps, and onlays cover one or more cusps or the entire chewing surface.

Q: When is an inlay recommended over a filling?
A: An inlay is recommended when the damage or decay is too extensive for a filling but not significant enough to require a crown.

Q: What materials are used for inlays and onlays?
A: Inlays and onlays are typically made from porcelain, composite resin, or gold, with porcelain being the most popular for its natural appearance.

Q: Are onlays stronger than traditional fillings?
A: Yes, onlays are more durable than traditional fillings because they cover a larger surface area and provide additional structural support.

Q: How long do inlays and onlays last?
A: With proper care, inlays and onlays can last 10 to 20 years, depending on the material used and oral hygiene practices.

Q: Can inlays and onlays be done in one visit?
A: Modern technologies, such as CAD/CAM systems, enable same-day fabrication and placement of inlays and onlays in many cases.

Q: Are gold inlays still used in modern dentistry?
A: While less common, gold inlays remain an excellent option due to their durability and biocompatibility, especially for back teeth.

Q: How much do inlays and onlays cost?
A: Costs vary depending on the material, complexity, and location, ranging from Rs. 7,500 to Rs. 40,000 or more per tooth.

Q: What is the process for placing an inlay or onlay?
A: The process involves removing decayed or damaged tissue, taking an impression or digital scan, fabricating the restoration, and bonding it securely to the tooth.

Q: Can fillings be upgraded to inlays or onlays?
A: Yes, older fillings can often be replaced with inlays or onlays to provide better strength and aesthetics.

Q: How do these options affect tooth strength?
A: Inlays and onlays strengthen the tooth by reinforcing its structure, while fillings primarily restore functionality without additional reinforcement.
