The species received its German name to the two characteristic ‘little teeth’ in the aperture of the shell. The animals live in marshy river floodplains, reed meadows and in the siltation area of standing waters. All known populations of the species have been destroyed by bank stabilisation, drainage and river regulation. The two-toothed snail is currently considered ‘lost’ in Salzburg.

The animals mainly live in damp, semi-natural meadows on calcareous ground, which is considered worth protecting. For this reason, the narrow-mouthed snail was included in Annex II of the EU Habitats Directive. The highly coiled shells of the species measure only about 1.8 mm. Small teeth and folds are formed around the aperture of the shell. This is to prevent predators from penetrating the snail's shell.
