We decided we'd rather be a peasant than a member of a noble family but an advantage of being a noble would be bathing and keeping your clothes clean...if you were a peasant you'd have to wash your only set of clothes at the same time as your body and that was only about twice a year in the nearest river.
But a nobleman or woman bathed at least four times a year and had spare clothes to change into while the rest of their wardrobe was washed...by a washerwoman pounding the linens on rocks by the riverside.
She would have used soap...a cake of good quality white soap for fine linens which came from Northern Spain and cost about 4d and is still called Castile to this day... and a much cheaper harsh black soap which had been made locally which was liquid...you bought it by the bowlful. The washerwomen had permanently blistered legs, arms and hands from using the cheaper caustic soap...in the absence of a river or lake, they washed the clothes in wooden tubs which were big enough to stand in while you trampled the linens underfoot.
So, that's your clothes sorted. Now, what about bathing yourself? There were public spas and baths where gentlemen could go and soak in water scented with rose petals and lavender while having their backs scrubbed by a nubile young woman. As prostitution was ignored, the public baths offered the opportunity for the gentlemen to indulge in more than a back scrub if they so wished.
Ladies were bathed at home by their maidservants...but their hair would have been washed weekly using a mixture of spices because the soaps were simply too caustic. It wasn't so much the fact that people liked being dirty...the moralists of the 1300's frowned upon frequent washing and bathing as being a sign of vanity and criticised the Danes because they combed their hair daily and bathed every week.
And teeth cleaning...we all know how important regular tooth cleaning is for keeping decay and bad breath at bay...in the 1300's rotten teeth were less important than having sweet smelling breath so everyone chewed cardamom, aniseed or fennel to keep their breath fresh. Sugar in various forms had begun to make an appearance at table which led to the formation of caries but that connection was lost on the people then...it was the worms who burrowed into your teeth which caused the problems...not your recently acquired taste for sweetness.
So, how to rid your teeth of those pesky worms...opium was one solution...at least it would have taken the pain of toothache away if nothing else. If you couldn't afford opium then you could use a candle made from mutton fat into which you'd pressed the seeds of sea holly...holding the lighted candle as close as possible to the affected tooth while leaning over a bowl of water will make the tooth worms fall into the water and drown.
If that didn't work you could go to a tooth drawer who'd yank the tooth out for you...
And he could make you a set of false teeth...but they were wooden and didn't fit terribly well and there wasn't a dental fixative in a handy tube like nowadays...

So, although in general I'd have preferred to be an ordinary peasant I'd have liked enough money to be able to buy a regular supply of opium actually...for me teeths. And I'd have liked to have bathed four times a year rather than twice...and had clean clothes to put on. And a maid to comb my hair and squash the head lice.
