Quick answer
Professional vs. At-Home Teeth Whitening
Professional whitening uses higher-strength gel under supervision, giving faster, more even results with less gum irritation. Store kits are cheaper but weaker and use generic trays. Custom take-home trays from your dentist are a middle ground.

In-office whitening
Several shades brighter in about an hour — ideal before an event.
Custom take-home trays
Dentist-made trays fit your teeth so gel stays where it belongs.
Store-bought kits
Convenient but slower, and strips may miss curved teeth.
