You can use a tooth pick.
In some cultures, showing teeth can be considered rude or aggressive, particularly when it involves smiling or baring teeth in a confrontational manner. For example, in certain Indigenous cultures in the Pacific Islands, exposing teeth may be seen as a sign of aggression or disrespect. In contexts where a smile is not customary, such as formal or solemn occasions, showing teeth may also be viewed as inappropriate. Always consider the cultural context to avoid misunderstandings.
It's not appropriate to do it in public places.
