Sometimes it is beneficial to not stitch the area of treatment due to several clinical reasons which would be in the best interest of the patient's healing, etc. Leave this judgement upto your dentist/surgeon as they would know best what would be ideal in your specific situation..
Hello, if you had implants placed 6 months ago and your gums are fully healed you can use denture glue while you wait for the to be clipped over your dentures, yet it would be best to have them clipped soon, regular implant integration takes 4-6 months so you are safe to have your dentures...
If the tooth was for extraction it is probably because there was an infection which triggers bad odor. The next thing would be that after the extraction of the infected tooth, the odor improves.
