Teeth whitening strips are an at-home whitening option that provides a convenient way to brighten teeth. These strips are coated with a peroxide-based whitening gel and are applied directly to the teeth for a specified duration. Clients should be instructed on the proper use of whitening strips, including how long to leave them on and how frequently to use them. This tip is particularly useful for clients who want to maintain their whitening results between professional treatments. Proper usage of whitening strips can help clients achieve consistent, safe, and effective results.
