Korea is an excellent place for teeth whitening since dental procedures are generally affordable and high quality. Here's what to know:

In-office whitening: 200,000-500,000 won per session. Uses strong peroxide gel with LED or laser activation. Takes about 1 hour. Most dramatic results.
Custom take-home trays: 150,000-300,000 won. The dentist makes custom trays for your teeth and gives you professional-grade whitening gel to use at home for 1-2 weeks.
Scaling + whitening combo: Many clinics offer packages. Scaling is covered by insurance once a year, so you only pay for the whitening part.

Whitening strips: Available at Olive Young and pharmacies. Brands like Crest (imported) or Korean brands. 15,000-30,000 won.
Whitening toothpaste: Median, 2080, and Perioe brands all have whitening versions. 3,000-8,000 won at any convenience store.
LED whitening kits: Available on Coupang. 30,000-80,000 won. Results vary.

Should you go to a dentist?

For best results, definitely yes. Professional whitening is much more effective than at-home products.
Korean dental clinics are modern and well-equipped
Many dentists in Gangnam, Sinsa, and near university areas speak English

Search on Naver Map for dentist or whitening
Check reviews on Naver or Kakao Map
Gangnam and Sinsa areas have the highest concentration of cosmetic dentistry clinics

Get a dental scaling first (covered by insurance once per year for about 15,000 won copay). Clean teeth whiten better.
Sensitivity is normal for a few days after professional whitening
Avoid coffee, tea, and dark foods for 48 hours after treatment
Results from professional whitening typically last 6-12 months
