Lay back, relax, and wait for whiter teeth while enjoying the soothing treatment room at WestcoastSmile. Aromatherapy, dimmed lights, falling water, massage chairs, ambient music and a paraffin wax hand treatment make this whitening procedure feel more like a spa visit than a trip to the dentist. To ensure effective whitening, new patients are asked to have a dental examination and professional cleaning within 30 days of starting treatment.
