Depending on the active ingredients they contain, different types of mouth
rinse can be used to prevent dental caries, periodontal disease or reduce
Fluoride mouth rinse
Most of the fluoride mouthrinse on the market contains 0.05% Sodium Fluoride

toothbrushing, but it must be used under the dentist's instruction

toothbrushing is impossible.
Desensitizing mouth rinse is only suitable for
people with tooth sensitivity. It is advisable to consult your dentist
before you choose to use it and follow his instructions in using desensitizing
