Garden Treatment.

Before we moved in, the previous owners of out house treated the garden for dandilions, in the summer.

When will it be ok for the buns? I am not sure??

Depends what they were treated with. Dandelions are perennial weeds so it's likely to have been a systemic herbicide which will have been absorbed by the leaves and taken down into the roots. You really would need to know what the chemical was that was used to know how long any residue will remain in the soil.
