Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you develop new or persistent tongue, lip, jaw, or facial movements.
Bring a complete medicine list, including medicines you have stopped and non-prescription products.
An earlier appointment is appropriate if the movements are worsening, causing mouth injuries, or affecting eating or speech.
And for anyone, someone who:
has noticed a lump, a mole that has changed, or unexplained weight loss

Sudden one-sided facial weakness is not typical linguofacial dyskinesia and may be a sign of stroke.
Every sign above is quoted from the sofidex article on Linguofacial dyskinesia. If you are not sure, err upward — it is always reasonable to be checked.
