Whitening trays
Over-the-counter versions ($45 to $75 for a two-week supply) lighten teeth only a shade or two; home-whitening trays custom-fit by your dentist ($300 to $800) give more dramatic results.
You can also get whitening done in-office for $500 to $1,000; it's no better than using custom trays, but takes under two hours.
