Wearing Invisalign aligners can affect your diet in a number of ways. When you only have 2 hours of throughout the day to spend with your aligners removed (ie. on meals and cleaning your teeth), you may find that you start avoid snacking. Talk to your general health care provider or nutritionist about whether you need to set up an nutritional plan for the duration of your treatment. Also, your mouth may salivate excessively when your aligners are in, which could lead to some dehydration. So, we recommend increasing your water consumption. Water should be the beverage of choice when you are wearing your aligners.
