There's a party in my mouth and you're invited!

"...The Oral Disco is a multi-coloured light cleverly concealed inside a plastic mould. This easily and comfortably slides onto your upper or lower teeth. When you switch it on, it makes your whole mouth glow in an array of colourful light! The light moves from tooth to tooth as if dancing, hence the ‘disco' name...."
