thank you for your post youre literally the first person whos ever shared this same thing ive struggled with myself its nice seeing all the comments and knowing im not alone  i really struggle with sensory issues too not sure if this is helpful for you but i found using an electric toothbrush massively helped since i switched ive always had positive comments from dentists  think its something about the fact the brush is vibrating rather than crunching against my teeth and the small round shape of the bristles rather than a big chunky rectangle that makes the difference  anyway good work - keep it up and be gentle with yourself if you miss a dayeven though its basic hygiene its still hard forming new habits and youre doing great
