My first-ever extraction of an adult tooth was a molar (I think) some twenty-odd years ago. Because of inability to schedule the extraction (it was an emergency, due to inflammation and pain), it was done on the afternoon of the day that the family started a one-week vacation trip. I had some of the same concerns that you have now, I’m sure: what is this going to do to my plans?
The dentist had given instructions on how to avoid complications: soft foods and soups, no sucking through straws or equivalent (because the vacuum that would create in my mouth could threaten sutures and cause bleeding), pain meds, etc. etc.
In the end, the extraction caused me zero problems, and I didn’t even need the pain meds. (I was advised to keep a wadded gauze pad pressed in place for the rest of the day of the extraction, and that was bloody and uncomfortable as the extraction site started its healing process that day. But that was not “painful”, just swollen, tender and – for the rest of the afternoon – a bit bloody. The trip was otherwise enjoyable, and the next morning I was fine.) I think I may have had three extractions since then; the first was the worst.
The only issue that I had with that first one was that chewing brittle foods such as potato chips, for example, or hard foods such as nuts and seeds, did cause problems and tenderness on that side of my mouth, when I would forget myself. So I would definitely recommend that you avoid such foods until the sutures are healed and the gum in that area is somewhat toughened from exposure to normal chewing, food textures, temperature changes, etc.
Regarding the implant, however, my first implant was begun nearly ten years ago when I had the implant itself – with its temporary cover plate (not a temporary crown) – installed, with instructions to come back in six months or so for the crown. Because of various reasons, I never did get around to having the crown placed… for about six years. The temporary implant plate caused zero problems: no pain, no unsightliness (it was for another molar, after all), no trouble or effect on eating, drinking, speaking or any other oral activity. (As I recall, and just like with any other dental procedure, it took several days – maybe even weeks – for my tongue to get used to the new feel of my mouth, but that’s normal – at least for me – with nearly any dental work.)
When I finally had the new implant put in by another dentist (and I was so afraid that he would criticize and cavil about the earlier dentist’s work, the time that had elapsed and the conditions that he’d be starting from – but there were zero complications there, either), the new implant felt – for weeks! – as if I had a cement column installed in my mouth. Boy, was that awkward for awhile. It felt huge; it felt rough; it felt like it didn’t belong in my mouth at all. But in short order I got used to it, and have had no problems with it.
I’m sure you’ll be fine. Enjoy your travel! Mind the potato chips and mixed nuts.
