After even minor trips to the dentist for routine check-ups, you may be instructed to avoid eating to ensure that your treatment is as effective as possible. With more serious procedures, you may be instructed to not eat for a short period of time and then to only eat very soft or liquid foods for up to 7 days following treatment. This standard is important to maintaining the dental implants you’ve just received, as any deviation from the soft food diet could result in a malfunctioning implant.
