Types of Teeth Whitening Procedures
Teeth whitening options range from over-the-counter to professional treatments. Whitening toothpastes lighten teeth by one or two shades through polishing. Whitening strips are peroxide-based and show results in about two weeks, lasting up to four months, costing between $10 and $60. Whitening gels are applied directly to teeth and also last around four months, costing $15-$20. Professional whitening involves dentist-applied gels and light, offering the most significant color improvement and lasting results, but can cost up to $800.
