Aspects to consider

For these natural remedies to have the desired effect, it is essential to apply them constantly; however, if the sores remain for more than three weeks or seem to be getting worse, it is best to see your doctor immediately.

Despite the fact that these remedies are innocuous, it is best not to apply them all at once but to intersperse them. For example, you can rinse your mouth with aloe vera gel and then apply ice for a few minutes. Then the area is left to “rest” and, in case of discomfort, the same or another remedy is applied.
