Years ago I had a mould made by my dentist and regularly whitened my teeth. Due to becoming hypo and unable to afford dental appointments, whitening fell by the wayside.
I now wish to revisit this but have concerns as to whether this is a good idea due to being hypo. Does anyone know if there are any risks involved? Certainly it would appear that there's been some tightening up of buying these products.
Second question is to do with a dental irrigator - I've bought one and am struggling to find any info re how often this should be done. Anyone know?
