Thank you for shopping at Oki. We want you to be completely satisfied with your purchase, and we understand that sometimes things don’t work out as expected. That’s why we offer a hassle-free replacement and refund policy to ensure your peace of mind.

Replacement Policy

At Oki, we strive to create a custom night guard that fits perfectly. If you experience any issues due to:
✅ Manufacturing defects
✅ Improper fit due to impression inaccuracies
✅ Operational errors (e.g., typing mistakes on your order)
✅ Errors caused by Oki (e.g., loose, tight, or uncomfortable fit)
✅ Package loss or missing items

We offer a free replacement to ensure your night guard meets your needs.

Exclusions

Our replacement policy does not cover:
❌ Natural wear and tear from teeth grinding
❌ Discoloration due to improper care
❌ Bacterial buildup
❌ Wrong thickness or size selection by the customer

If replacement is required due to these reasons, an additional fee may apply.

Return of Defective Products

If a replacement requires us to remake your night guard, you must return the defective product for evaluation and testing. Without the original product, we cannot proceed with a replacement.

📌 Note: During the thermoforming process, a 20%-40% thickness reduction is normal. This is not covered under our replacement policy.

📦 Shipping Cost: We cover the shipping cost for all eligible replacements.

If you are not satisfied with your purchase, you can return your custom night guard within 60 days of receiving it.
