Do you have cracked teeth or a large cavity that doesn't require a full crown? Dental inlays and onlays are a conservative solution that restores the strength and function of your tooth while preserving as much of your natural smile as possible.
At Elegant Smiles in Las Vegas, NV, we help patients know their options and choose the right treatment for their needs. If you're wondering how to fix a broken tooth or are facing other common dental issues, call now to schedule a consultation.
How dental inlays and onlays work
Inlays and onlays are common dental restorations used to repair teeth that are too damaged for a single filling but not severe enough for a full crown. They're made from materials like porcelain or composite resin and are made to fit precisely into or over the affected area of your tooth. Whether you require one or both treatments, inlays and onlays are designed to restore strength, protect the tooth, and blend seamlessly with your natural smile.
Inlay vs onlay: What's the difference?
The main difference between an inlay vs onlay comes down to how much of the tooth they cover. An inlay is used when the damage is confined to the center of the tooth or between the cusps. An onlay, sometimes called a partial crown, is used when the damage extends out to one or more cusps or covers a larger portion of the tooth.
During an appointment at Elegant Smiles, we will evaluate the damage and recommend the option that fits your needs. Dental inlays and onlays are great for several situations:
- You have a large cavity that's too big for a traditional filling
- You have cracked teeth that need reinforcement, but don't require a crown
- You want to preserve as much of your natural tooth structure as possible
- You need a durable, long-lasting restoration
Unlike fillings, which can weaken over time, inlays and onlays are incredibly strong and can last 10 – 30 years with proper care. They're also less invasive than crowns, which require more of the tooth to be removed.
How we place your dental restoration
Want to know how to fix a broken tooth with an inlay or onlay? During an appointment at Elegant Smiles in Las Vegas, NV, we will remove the damaged or decayed portion of the tooth and take impressions or digital scans. A temporary crown may be placed to protect the area while your custom inlay or onlay is being made. The restoration is then carefully fitted and bonded to your tooth. We will make any necessary adjustments to ensure a comfortable bite and seamless appearance.
Caring for your inlays and onlays
Caring for dental inlays and onlays is simple. Brush and floss every day, just as you would your natural teeth. Avoid biting down on objects like ice or pens, and visit Elegant Smiles regularly for checkups and cleanings. With consistent care, your inlay or onlay can last for many years, providing strength and protection without the need for more invasive treatments in the future.
