I had all my upper teeth pulled 10 days ago. should i wear my denture all day and all night or should i take them out when i sleep?

Dentures: It is best to take our dentures out during the night . Continue to follow up with your dentist during this healing period. The fit of your denture will change as you heal and you will need adjustments.

Full dentures: In general, removable dentures should be taken out at night in order for your gums to "breathe". Having said that, this is a question you should discuss with the dentist actually treating you as it is his\her responsibility for your aftercare and well-being and not for a dentist over the internet to advise you what you should or should not do.

Remove them at nigh: It is recommended to have the denture soak in cleaning solution while you are sleeping... That keeps the mouth and the denture fresh
