GlaxoSmithKline (GSK) has added a new fresh mint mouthwash and flexible toothbrush to its Aquafresh Complete Care range.

The products, which launched on August 1, will communicate a new claim of 24-hour protection against sugar acid that extends to the Whitening, Extra Fresh and Original toothpastes in the range.

Using fluoride-containing products and brushing twice daily can protect against acid by strengthening enamel and promoting mineralisation, GSK explained.

The manufacturer said it hopes the new information will “invigorate sales” of its oral health products.

GSK will spend £2.5 million on marketing the products, including in-store “promotional activity” and a TV advertising campaign, which started in July and will run until the end of October.

The Aquafresh Complete Care Mouthwash retails at £3.49 for a 500ml bottle, and the Aquafresh Complete Care Toothbrush is £2.99.
