A bright, white smile can boost confidence and make a lasting impression. With numerous whitening options available, understanding the differences between professional and at-home treatments is crucial for making an informed decision.

Understanding Tooth Discoloration

Types of Stains

  • Professional supervision ensures safety
  • Customized treatment based on individual needs
  • Immediate problem-solving if sensitivity occurs
  • Higher upfront cost ($500-$1,500)
  • May cause temporary sensitivity
  • Results can fade without maintenance

Take-Home Professional Kits
