Hello dear and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
Your symptoms can be related to many medical conditions.
The most common cause can be microtrauma associated with dentures.
Other possible causes can be smoking tobacco or alcohol.
No treatment is required.
It will probably go away in a few days.
If the black spot continue for more than a week I recommend to visit an ORL specialist for a physical examination.
