A temporary crown is a protective covering placed over a tooth prepared for a permanent crown. This interim restoration is typically made from resin or acrylic, which is less durable than the final crown. It is secured with temporary cement, designed to be easily removable by the dentist. Because the material is less robust and the cement is weaker, careful dietary modifications are necessary to prevent damage, dislodgement, or fracture.
Foods That Must Be Avoided
Foods must be categorized carefully to minimize mechanical forces that could compromise the temporary crown. Hard and crunchy items risk fracturing the crown material or loosening the bond by applying excessive pressure during biting. These items include:
- Hard candies
- Ice
- Popcorn kernels
- Nuts
- Raw, firm vegetables like carrots
Sticky and chewy foods are particularly dangerous because they adhere strongly to the crown’s surface and can pull it away from the tooth. The adhesive forces generated by items like chewing gum, caramel, toffee, and very crusty bread can exceed the retention strength of the temporary cement. This action easily dislodges the restoration, exposing the sensitive prepared tooth underneath.
Extreme temperature items should also be limited, even though they may not mechanically dislodge the crown. The prepared tooth beneath the temporary crown is often sensitive, and exposure to very hot or very cold foods and drinks can cause significant discomfort. While temperature extremes can potentially weaken the temporary cement, sensitivity is the primary concern.
Recommended Safe Foods
Selecting soft, non-abrasive, and temperature-neutral options is the best strategy for protecting a temporary crown. Dairy products like yogurt, cottage cheese, and soft cheeses can be consumed safely without risk of damage. Cooked starches and vegetables that are soft enough to mash, such as mashed potatoes, well-cooked pasta, and smooth soups, are excellent choices.
For protein sources, soft options like scrambled eggs, flaky fish, and soft tofu are recommended. The goal is to choose foods that require minimal chewing force and lack the tensile strength to pull the crown off. Soft fruits such as bananas and applesauce, along with cooked cereals like oatmeal, provide nutrients without posing a threat to the restoration.
Safe Eating Techniques While Wearing the Temporary Crown
The manner in which food is consumed is just as important as the food choices for protecting the temporary crown. Patients should chew food exclusively on the side of the mouth opposite the temporary crown to minimize direct forces on the restoration. This shifts the bulk of the masticatory load to the secure side, greatly reducing the risk of dislodgement or fracture.
To further reduce stress, cut all food into small, manageable pieces before eating. This practice minimizes the tearing or pulling actions that can loosen the crown. It is also important to completely avoid biting directly into food with the temporary crown; items like apples, corn on the cob, or sandwiches should be sectioned first.
The temporary cement is designed to last for a limited period until the permanent crown is ready for placement. These dietary and chewing restrictions must be maintained diligently until the dentist removes the temporary crown and permanently cements the final restoration. Opting for lukewarm food and beverages will also help manage any sensitivity that may be present during this period.
