Although a special diet should not be followed after masseter botox treatment, there are some points to be careful about. In this context, it is necessary not to chew hard foods, especially for the first 12 hours after masseter botox treatment. On the day of masseter botox treatment, care should be taken to consume liquid or pureed foods that do not require much chewing. Chewing gum, consuming large amounts of snacks and hard meat products can cause intense chewing movements and thickening of the jaw muscles.
