After tooth extraction, the dentist will evaluate the need for stitches/sutures. There are two types of stitches/sutures. One should confirm the type of suture with the dentist, if used.
Non — absorbable sutures won’t degrade and will only reduce in strength over time. They have to be removed 7 – 10 days after the stitches were originally placed.
Resorbable sutures (plain gut/chromium gut) get resorbed and do not have to be removed. They may deteriorate over 8 – 15 days. But, it may take 70 – 90 days for them to be completely resorbed within tissues. Resorbed means that the suture material will be broken down and assimilated gradually.
