Final answer:
The patient likely developed a dental abscess due to untreated dental caries or gingivitis. This can happen when pus from an abscess breaks through the buccal or lingual cortical plate post tooth extraction. Treatment involves good dental hygiene, drainage of the abscess, and antibiotics.
Step-by-step explanation:
The patient's symptoms after tooth extraction might be indicative of a dental abscess, often the result of untreated dental caries or gingivitis. Cavities or dental caries can cause damage to the teeth and can eventually infect the underlying dentin or pulp. If not treated, the infection can form an abscess which can extend to deeper tissues such as the root or even to the bloodstream.
An abscess can appear when pus from said abscess breaks through the buccal or lingual cortical plate without perforating the overlying periosteum. This can also happen after a flap has been raised during a surgical procedure, such as a tooth extraction. Typically these abscesses are painful and can cause redness, irritation, and swelling of the gums.
Proper dental hygiene plays a vital role in preventing the progression of dental caries and gingivitis which can lead to more serious conditions such as a dental abscess. In severe conditions, antibiotics such as tetracycline or doxycycline can be prescribed. Treatment for the abscess would typically involve drainage and potentially more antibiotics to eliminate any residual infection.
