After-Care Instructions for Crowns and Bridges

Local anesthesia usually takes 1 to 3 hours to wear off after dental treatment. During this period, avoid chewy and tough food, and do not bite your tongue or inner cheek unconsciously. Numb oral tissues are easy to get scratched or bitten without awareness, which causes unnecessary oral damage.
Temporary crowns and temporary bridges rely on weak temporary cement for fixation. The bonding strength is far lower than permanent cement. Many users experience loose or dislodged temporary restorations due to daily eating habits. Once the temporary crown falls off or feels abnormal, do not use household glue for self-repair. Improper adhesion leads to tooth displacement, gingival irritation and poor fitting for future permanent restorations. Leaving the tooth uncovered for a long time also causes tooth sensitivity and slight tooth movement, affecting the final crown installation.
Denture adhesive products such as Fixodent can be used for temporary fixation before formal re-cementation. Simply clean the crown interior and apply a small amount of adhesive for temporary stabilization.
Mild cold sensitivity and slight gum soreness in the first few days after temporary crown placement are very common in dental restoration cases. Overly cold or hot food stimulates the tooth surface and aggravates discomfort. Most sensitivity symptoms relieve gradually within three to five days.
Hard and sticky food is the main cause of temporary crown damage and falling off. Common problematic foods include chewing gum, hard bread, taffy, hard candy, nuts, popcorn and sticky glutinous food. These daily foods easily pull, crack or loosen temporary restorations, which are the top causes of rework in dental labs. It is recommended to chew food on the opposite side to reduce biting pressure on temporary crowns and bridges.
Daily oral cleaning remains necessary after temporary restoration placement. Use a soft-bristle toothbrush for regular brushing. When flossing, slide the floss out horizontally from the tooth side instead of pulling upward vertically. Vertical flossing is one of the most overlooked reasons for loose temporary crowns. Keeping the gingival margin clean effectively reduces plaque accumulation, bad odor and gingival inflammation.
Many dental technicians and clinic owners encounter similar common problems: temporary crown deformation, marginal gap, easy falling off and short service life. Most issues relate to material properties, milling precision and post-operative maintenance. Standard temporary restoration materials and accurate milling workmanship greatly improve the fitting effect and stability of temporary crowns, reducing after-sales problems and repeated adjustments for dental labs.
