After extraction along with analgesics to need to take antibiotics to prevent infection and to promote quick healing. i suggest you to take Augementin 625 mg along with diclofenac serratiopeptidase tablet twice daily for about 5 days . Definitly your swelling will subside . follow all the instructions your dentist had given post extraction. rinse your mouth regularly with lukewarm salt water or antiseptic mouthwash to keep the oral cavity clean, dont apply tooth brush in the extraction area, no smoking or alcohol for 5 days . i hope this will help you , take care

Hi,
Thank you for the query.
Swelling in your cheek indicates the severity of the infection in the teeth .Was the rootcanal treatment completed ? you didnot specify about it because if the treatment was not completed that shows the infection was still persisiting and after the extraction it will require some time to heal . So nothing to worry take a cousre of antibiotics- blueoxy- cvfor 5 days twice daily and anaglesics- keterol - dt will give you a fast relief.
Hope it helps you. Take care.

Some amount of pain and discomfort is expected for few days after tooth extraction. Amount of pain which occurs after tooth extraction is dependent on procedure which is used for the extraction of the tooth and the degree of trauma to the adjacent tissues.Pain can be managed after tooth extraction withover the counter pain medicaments.Analgesics are given after the tooth extraction to relieve the pain.During the first 24 hours after tooth extraction, you should take soft and liquid diet and should avoid taking food from the side where tooth was extracted. It is advised to do warm saline rinses 24 hours after the tooth extraction to reduce the pain and swelling. Take rest.You should avoid spitting, sucking, drinking anything with straw for minimum of 24 hours after tooth extraction and should not smoke for minimum of 2 days after tooth extraction.Smoking can create negative pressure and can cause dislodgement of clot and lead to dry socket.
It is also common to have pain in the jaw after the extraction as the mouth is held open for long time during the tooth extraction. Massaging the muscles gently, hot compresses application and over the counter analgesics can reduce the soreness of the jaw. Allow relaxation of the muscles and the jaw joint and don’t take hard crusted foods.
