The Impact of Diet on Orthodontic Treatment: What to Eat & What to Avoid

Find Confidence in Your Smile

Kees Grill

Orthodontic treatment is an investment in a healthier, more confident smile—but did you know that what you eat can affect your results? Whether you have braces, Invisalign, or a retainer, your diet plays a crucial role in keeping your teeth strong, preventing damage to appliances, and ensuring smooth progress throughout treatment.

At Cooper Orthodontics, we want our patients to have the best experience possible. That’s why we’re sharing how your diet impacts orthodontic treatment and what foods to enjoy and avoid for the best results.

How Diet Affects Orthodontic Treatment

The foods and drinks you consume can impact your treatment in several ways:

1. Protecting Your Appliances

Brackets, wires, and aligners are delicate and can be damaged by hard, sticky, or chewy foods. Avoiding these foods helps prevent broken appliances and delays in your treatment.

2. Preventing Tooth Decay

Orthodontic appliances create small spaces where food can get trapped, increasing the risk of cavities. A balanced, low-sugar diet reduces this risk and keeps your teeth healthy.

3. Strengthening Teeth & Bones

Calcium, vitamin D, and other nutrients help keep your teeth and jaw strong, supporting efficient tooth movement and a healthier smile.

Best Foods to Eat During Orthodontic Treatment

Soft & Nutritious Foods

  • Yogurt
  • Scrambled eggs
  • Smoothies
  • Mashed potatoes
  • Cooked vegetables
  • Soft fruits (bananas, berries, peaches)

Protein-Rich Options

  • Soft chicken or fish
  • Tofu
  • Beans and lentils
  • Nut butters (like peanut or almond butter)
  • Calcium & Vitamin D Sources

  • Almonds

Hydration is Key!

Drink plenty of water to keep your mouth clean and rinse away food particles. Avoid sugary drinks like soda and sports drinks, which can lead to cavities.
