Roridula dentata is currently not listed on the South African Red Data List of 1996. However, the Millennium Seed Bank team based at Kirstenbosch are working with the Threatened Species Programme (TSP), currently revising the Red Data List under IUCN guidelines.

It has been noted that although this shrub had a wide distribution historically, many populations listed in herbaria are no longer in existence. This is due to too frequent fires; fires at the wrong season when seeds are germinating; and habitat destruction by agriculture.

With the data now at hand it is envisaged that Roridula dentata may be given a status of Vulnerable (VU) or even Endangered (EN). Although seed from this species is known to have an ample longevity in storage, the parent plant often does not produce large quantities of seed. Thus there is often insufficient seed for seed banking and also to regenerate the soil seed bank in situ.

The most devastating threat to R. dentata populations is farming, specifically of rooibos, which is one of the only crops that can be grown in the mountains of the Cape, in the same habitat as this species. Due to the unique relationship of R. dentata with the insect, Pameridea marlothii, both species are rare or threatened: Pameridea marlothii  occurs only on R. dentata, a leggy insect that may hold the key to the growth and pollination of this perennial shrub.
