I first developed signs of a periapical abscess about two months ago (I have had quite a few in the past) but have been without a dentist since then. The tooth has been relatively pain-free for around seven weeks but over the last week or so I have some slight submandibular swelling on that side. I am due to have an initial consultation with a dentist in two days. When that tooth is eventually extracted, will the swelling recede, or is is likely to make things more complex?
