You should not eat or drink anything for at least 30 minutes after getting sealants. This will give the sealants time to harden and bond to your teeth. After that, you can resume your normal eating and drinking habits. Just be sure to avoid chewing on hard foods or candies, as this can cause the sealants to come off. Also, be sure to brush and floss regularly to keep your teeth and sealants clean. If you have any questions or concerns about your sealants, be sure to talk to your dentist.
