TrueLife SonicBrush K-series heads Whiten Plus black 2 pack
Replacement heads are specially designed for teeth whitening. The X-shaped rubber between the bristles glides easily over the teeth when brushing. This makes it easier to remove coffee or nicotine stains and polishes your teeth beautifully.
Each head can last up to 3 months of use, after which they begin to fray, lose effectiveness and accumulate bacteria. For convenience, the heads have special blue bristles that fade after 3 months, so you know exactly when it’s time to replace them.
