When over 50 percent of a tooth’s surface is injured, an inlay or onlay can help repair the damage. Arizona Family Dentistry offers inlays & onlays, as well as many other restorative dentistry solutions.
Inlay and onlay restorations are made of composite resin, porcelain, or gold. These fillings are bonded to damaged teeth. Like a traditional filling, an inlay is placed inside the cusps of a tooth. However, onlays are used for more extensive tooth repairs. For that purpose, onlays extend over the cusps.
Gold has been the traditional choice for this type of dental restoration, but in recent years porcelain has grown in popularity. This is because porcelain is very strong and natural-looking. Porcelain restorations blend in seamlessly with the existing teeth.
Two visits are required to place inlays & onlays in Phoenix, AZ. At the first appointment, the decay or damage, or old filling will be removed. Then the affected tooth will be prepared for the new restoration. An impression will be made and sent to an outside lab. This will ensure the inlay or onlay fits your tooth and bite properly. Next, your dentist in Phoenix, AZ will place a temporary sealant to protect the tooth until the next visit.
When you return, the sealant will be removed. Your Phoenix, AZ dentist will then inspect the finished inlay or onlay and ensure a proper fit. If the restorations fit properly, it will then be permanently bonded to the affected tooth. The last step is to polish the surface to a smooth finish.
Traditional dental fillings can reduce tooth strength by as much as 50 percent. In contrast, inlays and onlays can add up to 75 percent more strength to a damaged tooth. This is due to the high-strength resins. What’s more, inlays & onlays can last as long as 10–30 years. For patients with not enough tooth damage to warrant a crown and too much for a filling, a dental onlay may be the right alternative.
