Shipping and returns

Shipping

Free shipping is available on retail orders over $50 within the continental United States. Dental professional orders are excluded. Shipping charges for other eligible orders are calculated at checkout.

Orders are processed and shipped within 5 business days, excluding weekends and holidays. This is the processing window, not the delivery time.

We are currently unable to fulfill international orders.

Marked delivered, but not received?

Check with your neighbors or property office, then allow 24–48 hours in case the carrier marked your package delivered before it arrived. If it still has not arrived, contact the carrier and file a claim.

TWICE is not liable for packages marked delivered by the carrier. If you purchased the “Satisfaction Guarantee Insurance,” you can also file a claim through the Customer Portal for help with a replacement.

Cancellations and address changes

Email contact@twicetwicellc.com right away if you need to request a cancellation or address change. Requests are not guaranteed once your order has entered processing.

Holiday delivery

During holidays or peak seasons, please allow 5–7 business days for delivery. High carrier volume may cause delays outside our control.

Returns and refunds

Unopened, unused items purchased on smiletwice.com may be returned within 7 days of delivery. Return fees, exclusions and other conditions apply.

Read the return and refund terms before starting your request.
