Only if it’s somehow injurious to flesh. The brightness of light and the loudness of sound correspond to the amount of energy contained, and naturally the extremely sensitive (and thus delicate) sense organs can’t cope with too much energy at once - but very high-energy, ‘bright’ invisible radiation, like UV or microwaves could just as easily damage the eyes. So it’s not the fact that it’s perceptively bright, but that it’s high in energy.
I’m not a scientist, and the next part is more WAGgish territory, but boldly I proceed nonetheless. The intensity of a taste depends, I assume, on the configuration of the sense receptors on the tongue. If a molecule fits well, it activates the sensors strongly; the chemical listed is just one that is shaped just right for your sweetness receptors. There’s nothing about that that should cause damage to your tongue.
