I you have not had anaesthetic during your clean then absolutely. Although your teeth may feel so clean that you don’t want to. If you have had an “AirFlow” stain removal treatment, you should avoid food or drink that may stain for 2 hours. This will include tea, coffee, red wine, cigarettes, beetroot, curries etc. For cleans that included an anaesthetic, food and drink should be avoided until all feeling has returned.
