Patients with fixed appliances should avoid certain foods to prevent damage to the appliance and maintain good oral health. Some foods to avoid include:
- Candies, snack foods, margarine, cheese, soft drinks: These foods are high in sugar and may contribute to tooth decay and damage the appliances.
- Whole milk, bacon or sausage, sweetened cereals, apple or berry pie: These foods are high in sugar and can also cause dental issues and damage to the appliances.
