The unpleasant taste that develops in your mouth after wisdom tooth extraction is the taste of blood, and it may last for about a day after your surgery. During this time, is not advisable for you to rinse your mouth, as the blood around the wound needs to clot in order for the wound to heal. Once the 24-hour post-extraction period has passed, you can gradually start rinsing and gently brushing, advises the Mayo Clinic.
Swallow your saliva periodically during the first 24 hours after surgery. During this period, the blood from the wound may mix with your saliva. Do not let too much saliva accumulate in your mouth, as this can dislodge the blood clot forming over the wound.
Drink 236ml. of water every hour after surgery to keep your mouth from becoming dry, which promotes bacteria growth. Avoid using a straw to drink water, since it can promote bleeding and cause the blood clot to dislodge.
Pour 1/2 tsp of table salt in a cup and mix in 227gr. of warm water. Mix the salt in the water until the salt completely dissolves. Rinse your mouth using all of the salt water -- bit by bit -- and gently spit out the solution. Repeat the salt water rinse every two hours. Do not begin doing the rinses until the 24-hour post-extraction period has passed.
Brush your teeth gently with a soft-bristle toothbrush to remove plaque and any food particles that accumulated during your post-surgery waiting period for brushing. Brush very gently around the wound to keep from reopening it.
