After your temporary onlay is placed, it is important to follow these care instructions while you await your final restoration immediately after your temporary onlay placement. It is important to avoid eating or drinking until the anesthesia has worn off to prevent possible injury to your lips, tongue, and cheeks. It's normal to experience some sensitivity to pressure, heat, and cold for several days following the procedure. What this should pass is your mouth adapts to the temporary onlay. If you experience discomfort, you can use desensitizing toothpaste. Your temporary restoration may be shaped slightly different than your original tooth. Your tongue may magnify these small differences, but you'll become accustomed to them within a few days. You should resume regular brushing and flossing immediately to keep the temporary onlay and supporting tooth free of plaque buildup and decay. However, use care when brushing around it and avoid flossing teeth adjacent to the onlay as this may cause it to come loose or fall off. It is common for a small portion of the temporary onlay to wear away or break off. However, if your temporary restoration comes off completely, save the temporary and call your doctor to resin it. It's important that your temporary restoration stays in place to protect the tooth from damage or decay and ensure the proper fit for your final restoration. If your bite feels uneven or if you experience persistent pain or sensitivity outside of the norm, it is important to contact your doctor's office for assistance.
