Aphtae on the tongue are not uncommon and affect at least everyone at least once in a lifetime. Some people are more burdened by them, others do not notice them at all. The initial phase of aphtha formation on the tongue usually goes unnoticed, only when it is already pea-sized and painful does it become noticeable.
During the healing process this is exactly the opposite. The pain suddenly disappears again and the tongue aphthae becomes smaller. If aphthae on the tongue occur frequently or permanently, a visit to the family doctor is recommended in order to perhaps be able to narrow down the possible cause. In general, however, they are harmless and disappear again as quickly as they were formed.
