Teeth straightening treatments like Invisalign or traditional braces can transform your smile, but they require proper care and maintenance. One crucial aspect of ensuring the success of your orthodontic treatment is watching what you eat. Certain foods can damage braces, interfere with aligners, or even prolong the treatment period. If you’re wondering which foods should you avoid during teeth straightening, this expert-backed guide has you covered.
Why Diet Matters During Orthodontic Treatment

Your diet plays a vital role in maintaining oral hygiene and the effectiveness of your orthodontic treatment. According to orthodontic specialists, foods that are too hard, sticky, or sugary can lead to broken brackets, stained aligners, and increased plaque buildup. Following dietary guidelines recommended by dental professionals will help you achieve the best results in the shortest possible time.
Top Foods to Avoid During Teeth Straightening
Sticky and Chewy Foods
Sticky and chewy foods can get stuck between brackets and wires, making them difficult to clean. They can also pull on braces and dislodge them. If you’re using Invisalign, sticky foods may stick to your aligners, causing discomfort and bacterial buildup.
Examples to Avoid
- Caramel
- Chewing gum
- Taffy
- Gummy candies
- Toffees
Hard Foods
Biting into hard foods can lead to broken wires or damaged aligners. Even if you’re using Invisalign, hard foods can cause discomfort if you eat them while your aligners are in.
Examples to Avoid
- Hard candies
- Popcorn kernels
- Nuts
- Ice cubes
- Raw carrots and apples (unless cut into small pieces)
Crunchy Snacks
Crunchy foods can exert unnecessary pressure on your braces or cause small pieces to get stuck in between wires and brackets.
Examples to Avoid
- Pretzels
- Chips
- Hard taco shells
- Granola bars
Sugary Foods and Drinks
Sugar increases the risk of plaque buildup and tooth decay, which is already harder to control with braces or aligners. Sugary drinks can also stain Invisalign trays, making them appear yellow.
Examples to Avoid
- Soda
- Sports drinks
- Candy bars
- Pastries and cakes
- Ice cream with caramel or nuts
Acidic Foods and Beverages
Acidic foods can erode enamel and cause sensitivity, especially if you have brackets or aligners that trap food particles against your teeth. According to the American Dental Association (ADA), prolonged exposure to acidic foods can weaken enamel, increasing the risk of cavities.
Examples to Avoid
- Citrus fruits (lemons, oranges, grapefruits)
- Vinegar-based dressings
- Soda and energy drinks
- Tomatoes and tomato-based sauces
Tough Meats
Chewy and tough meats require excessive chewing, which can be uncomfortable and put stress on braces or cause aligners to shift.
Examples to Avoid
- Steak (unless cut into small pieces)
- Beef jerky
- Ribs
- Whole chicken drumsticks (unless shredded)
Foods That Stain
If you have Invisalign, be mindful of foods that can stain your aligners, causing them to look dull and unattractive.
Examples to Avoid
- Coffee
- Red wine
- Berries (blueberries, blackberries)
- Soy sauce
- Curry
What Can You Eat Instead?
While it may feel like many foods are off-limits, there are still plenty of delicious and orthodontic-friendly options:
- Soft fruits like bananas, mangoes, and berries (in moderation)
- Cooked vegetables like steamed carrots, spinach, and zucchini
- Dairy products like yogurt, cheese, and milk (great for calcium intake!)
- Lean proteins like eggs, fish, and tofu
- Soft grains like oatmeal, pasta, and rice
Expert Tips for Eating With Braces or Invisalign
- Cut food into small pieces to reduce pressure on braces or aligners.
- Drink water frequently to wash away food particles and reduce staining.
- Use a straw for beverages that may stain your teeth or aligners.
- Remove aligners before eating (if using Invisalign) and brush before putting them back.
- Maintain good oral hygiene by brushing and flossing after every meal.
FAQs
Can I eat pizza while wearing braces?
Yes, but it’s best to opt for soft-crust pizza and avoid hard or crunchy toppings. Chewing tough crusts can damage brackets and wires.
Is it okay to chew gum with braces or Invisalign?
No, chewing gum can stick to braces, damage wires, and cause unnecessary tension on aligners. It’s best to avoid gum entirely.
Are smoothies a good alternative for hard fruits and vegetables?
Absolutely! Smoothies are a great way to get essential nutrients while avoiding damage to braces. Just be mindful of sugar content to prevent cavities.
Can I drink coffee with Invisalign?
You can, but it’s best to remove your aligners before drinking coffee to avoid staining them. Always rinse your mouth before putting aligners back in.
How can I reduce discomfort while eating with braces?
Stick to soft foods, cut food into small pieces, and chew slowly. Over-the-counter pain relievers can help manage any initial discomfort.
Can I eat popcorn if I have braces?
No, popcorn should be avoided as the kernels can get stuck in braces and cause damage or irritation.
What should I do if I accidentally eat something hard and my braces break?
Contact your orthodontist immediately to get the issue fixed. Avoid attempting DIY repairs, as this could worsen the problem
