The time to eat after filling depends on the filling material, usually you can eat after 2 hours, it is recommended to chew with the opposite side to eat soft food. The time you can eat after filling depends on the filling material, the material solidification time is different, the complete solidification time is different, now the filling material has ionic mixing material, silver mercury material and resin material. 1. Ion mixing materials, common glass ions, zinc polycarboxylate, mixing well filled into the cavity about two minutes to reach the clinical solidification, the center and bottom of the material needs 24 hours to completely solidify, in the absence of complete solidification of the teeth, easy to cause the material breakage or fall off. 2. Silver-mercury material, prohibited for those who are allergic to silver-mercury material, when filling, it takes 2~5 minutes to reach clinical solidification, and 24 hours to reach complete solidification, and it is only after complete solidification that the tooth can be used when eating. 3. Resin material, also light-curing material, after filling the resin into the cavity, the light will clinically solidify in 30~60 seconds, and it will be completely solidified after 2 hours, and you can use the tooth to eat at this time. Filled teeth need regular follow-up checkups to check whether the filling material has been dislodged or whether secondary caries has been produced. Do a good job of cleaning and maintaining intraoral hygiene on a daily basis.
