Make sure to keep food out of there and you will heal quickly.
There are two types of wounds to consider too. If a tooth that is "erupted" or exposed is removed the tooth socket must heal by filling in and growing epithelial cells over the space. This is referred to as healing by secondary intention and it will take longer to heal than a tooth that has been be exposed by "laying a flap" of tissue that can then be sutured (stitched) closed. The edges of the surgical wound are brought together and touch each other. The epithelial cells then grow across the incision space relatively rapidly. This is referred to as healing by primary intention. As a child you likely skinned your knee at one time or another. The scab took some time to eventually flake off. That is an example of secondary intention as the cells had to grow all the way across the skinned knee. You also likely cut your self and even with out stitches the edges of the cut approximated each other and the injury healed much faster. That is an example of healing by primary intention.
Finally, while the question was specifically about making "gums heal faster," we must recognize that any time a tooth is removed there is a bone injury that will take additional time to heal whether "exposed" or covered by soft tissue. Some tenderness may persist during this bone healing despite soft tissue (gums) being comfortable.
The good news is you are young so healing should be quicker (assuming you are a healthy individual). Warm salt water rinses can help healing and make sure you keep the healing sites nice and clean to avoid inflammation/irritation. Make sure you follow your provider’s post op instructions carefully and attend your follow up appointment.
Hope this helps!

It usually takes 7-10 days for the gums to partially close up and heal following an extraction. However, for the gums to fully heal it takes 6-8 weeks. Following an extraction one should not spit, rinse, smoke or use a straw for 24 hours. I recommend my patients to rinse with warm salt water a few times a day starting 24-48 hours after an extraction. Just keep the area clean, and allow the healing process to take place. You may also take Motrin or Ibuprofen, which reduces swelling and therefore allows healing to commence.
To help your gums heal faster, rinse with warm salt water two or three times a day. However, it will take about 4 to 6 weeks to completely heal after a wisdom tooth extraction.
