Yes, you will be able to eat normally after your Invisalign treatment. The clear aligners will need to be removed for eating and drinking. Please brush your teeth after every meal to ensure no food particles are sitting trapped in your aligners as this can lead to tooth decay. If you have attachments then it is best to avoid hard and sticky foods to prevent them from breaking and complicating the treatment progress. You are required to wear your Invisalign aligners for a minimum of 22 hours per day. It is important you follow these instructions in order for your teeth straightening treatment to work effectively.
