After the initial healing period, patients with All-on-4 implants can gradually introduce crunchy or hard foods into their diet. However, it is important to exercise caution and avoid biting directly into extremely hard or crunchy foods. Instead, it is recommended to cut them into smaller, bite-sized pieces to minimise any potential stress on the implants. Additionally, chewing slowly and thoroughly is advised to ensure proper digestion and to prevent any discomfort or damage to the implants.
