Frequently Asked Questions
How long does teeth whitening take?
Express whitening takes 30 minutes, premium whitening takes about 1 hour. You can walk in and get it done between shopping!
Is teeth whitening in Korea safe?
Absolutely. We use the same FDA-approved whitening agents used worldwide, applied by licensed dentists. Professional whitening is much safer than DIY kits.
How many shades whiter will my teeth get?
Typically 4-8 shades whiter with premium whitening. Results depend on your original shade and tooth condition. We'll show you a shade guide before starting.
Can I eat Korean BBQ after whitening?
We recommend waiting 48 hours before eating heavily pigmented foods like kimchi, gochujang, or drinking coffee. Plain rice, tofu, and light foods are fine immediately after.
