If there is a buildup of tartar on the denture and it seems your regular ultrasonic denture isn’t doing a great job, then you could visit your dentist. Dentists have their professional ultrasonic cleaner to remove tartars and debris buildup on your denture painlessly. At other times, your denture may only require submerging for a decent number of minutes in a good cleaning solution. This can be made from effervescent tablets, cleaning powder, or ready-made denture cleaning solution. With a good brush down after submerging in the solution, your denture could come out sparkling clean.
