Oral devices such as a pacifier, bottle cap, teething tools and toys, and methods for using the same are provided. An oral device includes a bulb portion configured to be disposed inside a mouth of a user and a wider neck portion coupled distally to the bulb portion and configured to be held by user's lips. The neck portion is configured such that, when it is sucked on by the user, the neck portion moves in the lateral direction transverse to a longitudinal axis of the oral device from a first, unexpanded configuration to a second, expanded configuration such that a lateral contact area of the neck portion with the user's lips increases. The oral device can include one or more expansion accommodation features that facilitate expansion and retraction of the neck portion. |
