A dental crown is a cap placed over a damaged tooth to restore its shape, strength, and appearance. After the procedure, knowing when you can safely eat depends on two factors: the dissipation of the local anesthetic and the initial setting time of the dental cement. Following post-procedure instructions is necessary to protect the new restoration and avoid complications.
The Immediate Post-Procedure Wait Time
The first step is to wait until the local anesthetic has completely worn off, typically one to four hours. Eating while your cheek, lip, or tongue is numb risks accidental biting and soft tissue injury. Once sensation returns, the focus shifts to the dental cement, which needs time to achieve an initial bond. For both temporary and permanent crowns, a minimum waiting period of 30 to 60 minutes is required before consuming anything. This time allows the cement to stabilize the crown before it is subjected to chewing forces.
Eating Guidelines While Wearing a Temporary Crown
If you receive a temporary crown, eating restrictions are stricter because the restoration is less durable than a final crown. Temporary crowns are made from materials like acrylic resin and secured with temporary cement for easy removal. The goal is to prevent the crown from cracking or becoming dislodged before the permanent one is ready. You must avoid chewing on the side of the mouth with the temporary crown for the entire period you wear it. Sticky foods, such as caramel, taffy, or chewing gum, must be eliminated as they can pull the crown off. Hard or crunchy items, including nuts, ice, and crusty bread, should also be avoided because they can chip or break the temporary material. Opt for soft foods like yogurt, scrambled eggs, or cooked vegetables to keep the restoration intact.
Caring for Your New Permanent Crown
Once the permanent crown is cemented, immediate restrictions ease, but caution is necessary. Although the initial bond is quick, the permanent cement requires up to 24 hours to reach maximum strength. During this first day, continue eating softer foods and avoid chewing directly on the new crown. After 24 hours, you can gradually return to your normal diet. Temporary post-placement sensitivity is common, and the tooth or gum tissue may feel sensitive to extreme temperatures for a few days or weeks. Long-term care involves regular brushing and flossing, and avoiding habits like chewing on ice or hard non-food items to prevent chipping.
