តើ ការបំភ្លឺធ្មេញ ជាអ្វី?

Teeth whitening is a popular cosmetic dental procedure that lightens teeth and helps remove stains and discoloration. It can be performed in-office by a dentist using stronger bleaching agents, or at home using custom-fitted trays with lower-concentration whitening gel. Results can last from several months to years depending on habits.
