Teeth Grinding Symptoms: What You Need to Know
September 17, 2025Starting Invisalign is exciting because every tray brings you closer to a straighter smile. But along with the progress comes a few changes in daily habits, especially when it comes to eating and drinking. Knowing what works well with Invisalign, and what to stay away from, makes treatment smoother and helps keep both your teeth and aligners in good condition.
This guide breaks down the best foods to enjoy, what to avoid, and a few everyday tips to make eating with Invisalign a little easier.
Foods That Work Well
When you remove your aligners before meals, you can technically eat most foods. Still, some choices are gentler on your teeth and easier to clean up afterward:
- Soft fruits like bananas, melons, or berries are simple to chew and less likely to get stuck.
- Cooked vegetables such as carrots, squash, or green beans are safe once softened.
- Dairy options like yogurt, cheese, or pudding are smooth and easy to rinse away.
- Tender proteins including fish, chicken, or scrambled eggs are filling without being tough on teeth.
- Grains and starches like rice, pasta, and quinoa provide energy and are easy to manage.
- Soups and smoothies can be especially soothing if your teeth feel sensitive after switching to a new set of aligners. Just be sure to take trays out before enjoying them.
These foods are less likely to leave behind stubborn food particles and are easier to clean from your teeth before you put your Invisalign tray back in.
Foods and Drinks to Avoid
Some foods can make life with Invisalign aligners harder, or even damage your aligners if you forget to take them out first:
- Sticky foods such as gum, caramel, and taffy cling to teeth and are difficult to clean away.
- Crunchy foods like popcorn, nuts, or hard candies can break into small pieces that wedge between teeth.
- Dark or staining foods including coffee, tea, red wine, and tomato sauces can leave marks on trays or cause discoloration on teeth.
- Sugary or acidic drinks like soda, citrus juice, and sports drinks can wear down enamel if trapped under aligners.
- Very hot drinks such as coffee or tea can distort aligner trays if you sip them without removing the aligners first.
Avoiding these foods does not mean you cannot enjoy them occasionally, but it does mean being careful. If you choose to indulge, take your trays out first, eat or drink, then rinse and brush your teeth before putting aligners back in.
A Note on Drinks
The safest drink when wearing Invisalign is plain water. Drinking anything other than water with your trays in carries some risk. Hot drinks can change the shape of the plastic, while colored drinks stain quickly. Even clear drinks that contain sugar or acid can be harmful, since aligners trap the liquid against your teeth.
Whenever you want something other than water, remove your aligners first. Afterward, rinse your mouth or brush your teeth before putting trays back in place. This small step helps protect your enamel and keeps aligners clear.

Keeping Your Aligners Clean
Good habits make a big difference in how comfortable Invisalign feels day to day. Here are a few basics to follow:
- Always remove your aligners before eating.
- Rinse or brush your teeth after eating, even if it is just a quick rinse when brushing is not possible.
- Clean aligners daily with a soft brush and mild soap or the cleaning solution provided. Avoid abrasive toothpaste that can scratch the plastic.
- Store aligners in their case whenever they are not in your mouth to avoid losing or damaging them.
Keeping both your teeth and your aligners clean reduces the risk of cavities, staining, and odors. It also ensures your aligners stay clear and comfortable throughout your Invisalign treatment.
Staying on Track with Invisalign
Wearing Invisalign means aiming for 20 to 22 hours each day. Frequent snacking can make this harder since trays need to be removed and cleaned every time you eat. Sticking to regular meals and limiting snacks helps you stay on schedule and keeps treatment moving forward.
It can also help to plan ahead. For example, carry a travel toothbrush and floss picks so you can clean your teeth when you are not at home. Keeping a water bottle nearby makes rinsing your mouth easy after eating or drinking. Small steps like these keep your treatment on track and your smile healthy.
Final Thoughts
Eating with Invisalign does not mean giving up the foods you love. It simply means being mindful of your choices, removing aligners before meals, and practicing good hygiene before putting them back in. With these habits in place, you can enjoy a wide variety of foods and drinks while keeping your Invisalign treatment moving forward.If you are considering Invisalign or have questions about caring for your aligners, the team at Regehr Family Dental is here to help.
