Types of Teeth Whitening Available

In-practice whitening uses a concentrated gel activated by a special light. Results are immediate, usually achieved in a single appointment lasting 60 to 90 minutes. Common brands include Zoom, Enlighten, and Beyond.

Take-home whitening kits involve custom-made trays and a lower-concentration gel that you wear for a set period each day, typically over two to three weeks. Results are gradual but long-lasting.

Combination treatments offer an in-practice session followed by a take-home kit for maintenance. Many Westminster practices offer premium combination packages, and it is worth asking about these when you book a consultation.
