  • Patent number: 4913176
    Abstract: A dental pick having an enlarged head for removing plaque between teeth is disclosed. The pick has a handle portion and an operational portion. The handle portion has two gripping portions to provide two different operational lengths for the pick. The operational portion includes a flexible neck portion and an enlarged head portion. Advantageously, the operational portion of the pick is of a substantially continuous, non-tapering thickness which enables the pick to be inserted into the interproximal spaces between adjacent teeth without the risk of becoming impacted. The pick is adapted to slide between adjacent teeth while in a vertical orientation, and is then rotated so that the larger vertical portion of the head assumes a generally horizontal orientation. Once the device is substantially horizontally oriented, the pick is agitated both vertically and horizontally so as to disrupt food, plaque and bacteria residing therein.
