Healing is a job for your immune system. Heavy drinking makes that job harder.
After an extraction, gum treatment or an implant, your body has to repair itself. If you drink heavily, that repair can be slower and less reliable. Here's what's behind that, and what we do about it.
What Healing Needs
A healing mouth relies on a stable blood clot, a good blood supply, immune cells to keep bacteria in check, and new collagen to rebuild the tissue. Heavy drinking interferes with several of those at once.
What Alcohol Does to It
Clinical reviews describe alcohol suppressing immune cells, reducing collagen production, and leaving wounds more open to infection. In surgery generally, alcohol may also interfere with blood clotting, which raises the risk of bleeding. In the mouth, these effects are linked with delayed healing, infection around extraction sockets, and trouble around implants.
We'll be straight about the limits of the evidence. Much of it comes from surgery in general and from clinical reviews, not large dental trials, so we don't quote percentages. The direction of travel is clear enough, though, to plan around.
Where It Shows Up in Dentistry
Extractions, where heavier drinkers are more exposed to complications such as dry socket. Gum treatment, where healing determines how well the result holds. And implants, where the bone has to knit around the post, which is part of the picture we described in our post on smoking and bone loss.
Medicines Matter Too
Some medicines don't mix with alcohol. The NHS advises not drinking at all while taking the antibiotic metronidazole and for 2 days after finishing it. Heavy drinking can also change which painkillers are sensible for you. That's another reason to tell us your units before treatment, not after.
What We Ask of You
If you need surgery, we'll usually ask you to avoid alcohol for the first few days while the area heals, and to cut back beforehand if you drink a lot. We may plan treatment in stages. None of this is a judgement. It's about giving the work its best chance, and not asking your body to do more than it can. We explain why we ask in the first place separately.
